SPEEDLAN 9200 User Guide Part # 34357-MNL Rev. B 4-5 Wireless menuChoose one of the options from the Wireless menu: •If you choose Configuration, you will be able to set the following radio parame-ters: SSID, wireless mode, channel, signaling rate, turbo mode, Tx power and preamble. For more information, see Configuration, page 3-44 for more details.•If you choose Tx Retries, you will be able to set the Transmit Retry Limit and Sig-naling Rate Fallback. For more information, see Max Tx Retries and Signaling Rate Fallback, Chapter 3.•If you choose Max Throughput, you will be able to set the Max Transmit Data Rate in Kb/s. For more information, see Max Throughput (Regulating Band-width), Chapter 3.•If you choose RTS/CTS and enable RTS/CTS for a particular node, it will refrain from sending a unicast data frame until the node completes the "RTS/CTS hand-shake" with the receiving node. For more information, see Request to Send (RTS) / Clear to Send (CTS), page 4-5.•If you choose Rx Threshold, you will be able to set the threshold for each mesh router on the network. For more information, see Receive (Rx) Threshold Param-eter, page 4-6 for details.•If you choose Blocked Links, you will be able to block or unblock mesh routers. For more information, see Blocked Links, page 4-8 for more details.•If you want to enter the number of times that a neighbor node can fail to reply to a neighbor discovery probe before it is declared unreachable, seeLink Expiration, page 4-9.Request to Send (RTS) / Clear to Send (CTS)RTS/CTS allows you to fine-tune the operation of your wireless LAN. RTS/CTS will help minimize collisions between transmissions from hidden nodes on the wireless network.When you enable RTS/CTS for a particular node, it will refrain from sending a unicast data frame until the node completes the "RTS/CTS handshake" with the receiving node.Here is how the process works:Node A transmits a RTS frame. Node B, on the receiving end, retrieves the RTS and sends a response with a CTS frame. Before Node A sends the data frame, it must receive a CTS frame from Node B. Both the RTS and CTS frames contain the length of the data frame to
Part # 34357-MNL Rev. B SPEEDLAN 9200 User Guide 4-6alert other nodes to wait to access the network, while the node initiating the RTS sends its data.To enable RTS/CTS, choose RTS/CTS from the Wireless menu. The following screen will appear. Figure 4-4: RTS/CTS•To turn on RTS/CTS, click the Enabled option. •To turn off RTS/CTS, click the Disabled option.•Threshold: The minimum size (in bytes) of unicast data frames whosetransmission will be preceded by a RTS/CTS handshake. The effective range is 50 through 1500. The optimal value depends on many factors, but a starting value of 100 is recommended. (The factors include the number of hidden nodes, the statis-tical distribution of frame lengths, and the amount of retransmissions caused by RF interference.) •Select those nodes for which you want to enable RTS/CTS and click the Apply to Selected Nodes button. Receive (Rx) Threshold ParameterFrom a single mesh unit connected to a mesh network, you can set the receive threshold (given in dBm), for every mesh router in the network. The receive threshold specifies the minimum acceptable receive level for a datagram (defined for signaling rates, depending on the Wireless Mode you selected on the Wireless Configuration page). Any datagrams
SPEEDLAN 9200 User Guide Part # 34357-MNL Rev. B 4-7 received below these levels will be discarded. This will provide better network stability for networks containing marginal links, since link state changes (and the corresponding routing changes) will be avoided for marginal links which are not capable of consistent communication. By clicking the Defaults button, the values will go to their default values. If you enter a value of 0 (zero), you are turning the receive threshold parameter off. Figure 4-5: Rx Threshold pageThe current Rx thresholds for your wireless mesh router(s) are listed in the Current Rx Thresholds section. Their signaling rates are also listed, as described above. If you click Default, it will load the current default setting for the Configurator. Click Apply when finished.
Part # 34357-MNL Rev. B SPEEDLAN 9200 User Guide 4-8Blocked LinksFigure 4-6: Blocking Mesh RoutersThis feature allows you to block all traffic from a specific hardware address. This is most often used when a marginal signal exists between two nodes in a mesh network, such that the network functions more reliably when no direct communication occurs between the nodes. To completely block a link you must perform the same action on the remote node. Note: If you blocked a mesh Link, the next time it is rebooted it will remain blocked. If you want to unblock the Link, make sure that the Blocked check box is not selected.Note: Click Apply when finished.Select the checkboxunder Blocked to blocka Link. Leave it unselectedwhen you want to leavethe Mesh Link unblocked.

Chapter 8Configurating SecurityParametersThis chapter covers those parameters needed to set up Security INTRODUCTIONOur previous 9200 products supported AES [advanced encryption standard] encryption used a single static key for all links in the mesh and all type of traffic over them. The new release adds support to WPA with TKIP & MIC and WPA2 with AES-CCMP which include a dynamic key management system. The new design also allows "Per Group" encoding of unicast and multicast packets as well as simultaneous and independent "Per Link" encoding of unicast packets in each link in the network.Wireless Security in SPEEDLAN 9200 units provide the following types of security: •WEP •WPA•WPA2 (RSN)•WPA/WPA2
Part # 34357-MNL Rev. B SPEEDLAN 9200 User Guide 8-2WPA and WPA2 are supported in SPEEDLAN Phase2 Release to provide the security for SPEEDLAN units in Mesh, Star, and PTP Network Topologies. WPA is a subset of the IEEE 802.11i specification. It replaces WEP with a strong new encryption technology Temporal Key Integrity Protocol (TKIP) with Message Integrity Check (MIC). It also provides a authentication scheme using either IEEE 802.1x or pre-shared key (PSK) technology.Like WPA, WPA2 supports IEEE 802.1x or PSK technology. It also includes a new advanced encryption mechanism Advanced Encryption Standard (AES) using the Counter-Mode/CBC-MAC Protocol (CCMP).There are 2 modes of WPA and WPA2 certification - Enterprise and Personal. Table below lists the authentication scheme and Encryption method used in each certification mode.WPA ad WPA2 Personal Mode certification is supported in SPEEDLAN 9200 Phase2 to provide per-link, per-packet encryption via TKIP with WPA or AES with WPA2.PSK Authentication PSK based authentication is supported in all three Network Topologies - Mesh, Star and Point to point (PTP). Using PSK authentication scheme, user configures a pre-shared key on both supplicant and authenticator SPEEDLAN units. This pre-shared key is used as the Pairwise Master Key (PMK) to derive four separate keys that will be used in protecting the link between two SPEEDLAN units. The collection of all four keys together is referred to as the pairwise transient key (PTK).Table 1: Modes of CertificationWPA WPA2Enterprise Mode Authentication IEEE 802.1 X/EAP Encryption: TKIP/MIC Authentication IEEE 802.1X/EAP Encryption: AES-CCMPPersonal Mode Authentication: PSKEncryption: TKIP/MIC Authentication: PSKEncryption: AES-CCMP
SPEEDLAN 9200 User Guide Part # 34357-MNL Rev. B 8-3 Table below lists the authenticator and supplicant in each Network Topology.Cipher Suites and Key ManagementCipher suites are sets of encryption and integrity algorithms designed to protect radio communication on wireless LAN, and they are:•WEP (Wired Equivalent Privacy) - a 802.11 standard encryption algorithm orig-inally designed to provide your wireless LAN with the same level of privacy available on a wired LAN. However, the basic WEP construction is flawed, and an attacker can compromise the privacy with reasonable effort.•TKIP (Temporal Key Integrity Protocol) - a suite of algorithms surrounding WEP that is designed to achieve the best possible security on legacy hardware built to run WEP. •CCMP (Counter Mode-CBC MAC) - an AES based cipher; which yields the high level of data privacy required by some enterprises, government agencies and other organizations. CCMP support is mandatory in both the 802.11i specifica-tion and WPA2. Pre-authentication will be optional for both 802.11i and WPA2. WPA replaces WEP with TKIP. WPA2 includes the advanced encryption mechanism AES into the support.SPEEDLAN unit uses the following cipher suites to protect unicast messages in Mesh, Star, and PTP networks, and the multicast/broadcast messages in Star, and PTP networks:•CCMP;•TKIP;•WEP-64, WEP-128 and 156.SPEEDLAN9200 unit uses the following cipher suites to protect multicast/broadcast messages in Mesh network:Table 2: PSK AuthenticationMesh Star Base Star CPE PTP Primary PTP SecondaryAuthenticator XX XSupplicant XXX

Part # 34357-MNL Rev. B SPEEDLAN 9200 User Guide 8-8Per CPE KeyWhen PSK is used in a Star network, CPEs can negotiate a pairwise cipher. However, any CPE can derive the pairwise keys of any other that uses the same PSK by capturing the first two messages of the 4-Way Handshake. This provides malicious insiders with the ability to eavesdrop as well as the ability to establish a man-in-the-middle attack. To prevent such kind of attacks, SPEEDLAN9200 supports per station PSK. The "Per CPE PSK" configuration page is used to configure a unique PSK for each CPE. Figure 8-4: Network Security-Per CPE PSK

B SPEEDLAN 9200 User Guide 8-20Enabling WEP Security Between a SPEEDMesh-Enabled Client and SPEEDLAN 9200In a SPEEDLAN 9200 network, you can authenticate a SPEEDMesh-enabled client (PDA or laptop) with a standard security called Wired Equivalent Privacy (WEP). WEP encrypts data that is being transmitted over the wireless LAN. WEP protects the wireless links between clients and SPEEDLAN 9200 routers. Note: WEP is an encryption scheme used to protect wireless data communications. WEP uses 64-bit, 128-bit or 152-bit key sizes to provide access control to wireless network and encryption security for each data transmission. To decode a data transmission, each point in a network must use an identical 64-bit, 128-bit or 152-bit key.To enable WEP security, do the following:1If the Network Security Configurations page is not displayed on your screen, choose Security from the Network menu. On the bottom section of the Network Security Configurations page, choose WEP from the Encryption Type drop-down list. "None" is selected by default. (If you select None, encryption is disabled.) 2Choose Hexadecimal or ASCII Text from the Key Format drop-down list.•"Hexadecimal" is a Base-16 numbering system. The means the 16 sequential numbers are used as a base unit (i.e., "0-9" and "A-F"). •In ASCII text, each numeric, alphabetic or special character is represented with a 8-bit binary number (i.e., a consecution of eight 0s or 1s). 3Select Key 1-3 from the Transmit Key drop-down list. 4Select the length for the Transmit key by choosing either 64 Bits,128 Bits or 152 Bits from the Length drop-down list. Note: 40-bit WEP and 64-bit WEP are two different names for the same encryption method. This level of WEP encryption has been called "40-bit" because it uses a 40-bit secret key along with a 24-bit initialization vector (i.e., 40 + 24 = 64). The same is true for 104-128 bit and 128-152 bit WEP.5In the "Key1-3 text" boxes, enter the key value. For hexadecimal: a maximum of "10 "characters for 64 bits, "26" characters for 128 bits and 32 characters for 152 bits). For ASCII: a maximum of "5 characters for 64 bits, "13" characters for 128 bits and 16 characters for 152 bits.)6Click Apply to implement your changes.

Part # 34357-MNL Rev. B SPEEDLAN 9200 User Guide 9-2Basics of IP Addressing IP Addressing is important because it tells the network how to locate the computers or network equipment connected to it. IP addresses are given so each computer or equipment on the network has a unique routable address. IP addressing provides the following information: •Provides communication between different platforms and diverse systems •Provides universal data transfer over large geographic distances •Has been "adopted" as a standard in the computer industry What is an IP address? An IP address is a unique 32-bit identifier that contains: •Four octets (e.g., decimal 192.0.2.56). •Two sections: the network address and the node address (also known as the host address).The following examples show the conversion of the same IP address into several different formats: •Hexadecimal (82.39.1E.38)•Binary (10000010.00111001.00011110.00111000). Internet Address Classes Understanding this methodology is difficult; therefore, let's explain this in easier terms. The first octet(s) defines the "class" of the address, which is the only method to tell the size of the network (how big) and where the internet address belongs. There are three main classes: •Class A: 35.0.0.0 •Class B: 128.5.0.0 •Class C: 192.0.2.0 -non-bolded text = Part of network address-bolded text = Part of local address (node section)
SPEEDLAN 9200 User Guide Part # 34357-MNL Rev. B 9-3 This specification simplifies the way routers handle the messages (packets) and speed up the forwarding process. In fact, IP defines five classes:•Class A addresses uses 1 octet for the network portion and 3 octets for the node (or host) section of the address. This provides up to 128 networks with 16.7 mil-lion nodes for each network. •First octet is assigned as network address •Remaining octets used for node addresses •Format: network, node, node, node •In IP address 49.22.102.70, "49" is network address and "22.102.70" is the node address—all machines on this network have the "49" network address assigned to them •Maximum of 16,777,216 node addresses •Class B addresses uses 2 octets for the network portion and 2 octets for the node (or host) section of the address. This provides up to 16,384 networks with 64,534 nodes for each network. •First 2 octets are assigned as network address •Remaining octets used for node addresses •Format: network, network, node, node •In IP address 130.57.30.56, "130.57" is the network address, and "30.56" is the node address •Maximum of 65,534 node addresses •Class C addresses use 3 octets for the network portion and 1 octet for the node (or host) section of the address. This provides 16.7 million networks with 256 nodes for each network. •First three octets are assigned as network address •Remaining octet used for node address •Format: network, network, network, node •In IP address 192.0.2.102, "192.0.2" is the network address, and "102" is the node address •Maximum of 28 or 254 node addresses
Part # 34357-MNL Rev. B SPEEDLAN 9200 User Guide 9-4•Class D •Range is 224.0.0.0 to 239.255.255.255 •Used for multicast packets (i.e., host sends out router discovery packets to learn all of the routers on the network) •Netmask = /32•Class E •Range is 240.0.0.0 to 255.255.255.255 •Reserved for future use Note: Class D & E should NOT be assigned to network assignment of IP addresses. In addition, the first octet, 127, is reserved. In each network defi-nition, the first node number (i.e., "0") is used to define the network (i.e., "255"). The last number is known as the broadcast address.Note: Public addresses can include a network address assigned from the network administrator or from the IP provider. Also, there is one network in each class that is defined for private use, allowing the creation of internal networks. These addresses are Class A: 10.0.0.0, Class B:172.6.0.0, and Class C: 192.168.0.0.
SPEEDLAN 9200 User Guide Part # 34357-MNL Rev. B 9-5 Subnetting a NetworkThe increasing number of hosts and networks make large impractical address blocks that are not smaller than 255. In order to keep the IP address block small, so routers can manage them more efficiently, a smaller network definition is created. This is called a subnet. Subnets are intended to: •Reduce network traffic •Optimize performance •Simplify management •Create more effective and efficient addresses for large geographic distances Default Subnet masks•Class A: 255.0.0.0. •Class B: 255.255.0.0. •Class C: 255.255.255.0. Note: Subnet mask is bolded and corresponds to the network portion of the IP address. What is a Subnet? A subnet allows you to create multiple networks within one Class A, B, or C network. Each subnet contains a netmask that helps routers identify the subnet beginning and size. What is a Subnet Mask?A subnet mask allows you to mask section(s) (depending on the class specified) of the octets in the network address. Each octet used in the subnet mask is assigned to a data link. The leftover octet(s) are assigned to the remaining nodes. For more information on subnetting, see the example below and Diagram of Subnetting a Network, page 9-6.Example of Subnetting: For example, a Class C network contains three masked octets (255.255.255). The last octet (0) identifies nodes (i.e., computers). If Router D is reading IP Addresses 192.0.2.1 (let's call this IP Address 1) and 192.0.2.64 (let's call this IP Address 2) on this Class C network, it would send IP Address 1 to Subnet
Part # 34357-MNL Rev. B SPEEDLAN 9200 User Guide 9-6A and IP Address 2 to Subnet B. The remaining nodes in each subnet (A through D) on this network can contain up to 254 pieces of network equipment (computers, printers, fax machines, bridges or routers, etc.). Diagram of Subnetting a NetworkFigure 9-1: Subnetting diagramStill confused? An easier method to explain this concept is to use the classic "mailing" analogy used in IP addressing. Consider that this network, called Long Street, is four blocks long. There are 254 houses on Long Street, and each block contains 64 houses. Houses 1 to 63 reside on Block A. Houses 64 to 127 reside on Block B. Houses 128 to 191 reside on Block C. Houses 192 to 254 reside on Block D. Think of each block as a subnet. This means that Blocks A, B, C, and D are all part of Long Street, which is also known as the network in this example. The mailman would organize the letters (or IP addresses for network InternetRouter DRouter BRouter CComputer ComputerComputerComputerComputer Computer ComputerComputer Computer ComputerLong StreetSubnet AIP Address: 192.0.2.1Subnet Mask: 255.255.255.192Subnet BIP Address: 192.0.2.64Subnet Mask: 255.255.255.192Subnet CIP Address: 192.0.2.128Subnet Mask: 255.255.255.192Subnet DIP Address: 192.0.2.192Subnet Mask: 255.255.255.192Router A
SPEEDLAN 9200 User Guide Part # 34357-MNL Rev. B 9-7 equipment) by creating four piles (one for each block, or subnet). As soon as the mailman picks up pile A in his hand, he knows which block to turn on. This same reasoning applies to piles B, C, and D as well. Router D knows exactly which subnet to transfer (or turn) the packets to by reading its IP and subnet mask address. Note that each subnet on this network is 255.255.255.192. Why is 192 the last octet in the subnet mask and not 64? The last octet, 192, is the mask that allows 64 "houses" to reside on the street. Note: If the network is managed by a Simple Network Management Protocol for local or Internet access, each interface must contain a unique IP Address. This is a benefit of static or dynamic addressing. How does a network administrator assign an IP address? IP addresses are supplied by the network administrator, the ISP, or hosting company. The two types of IP addressing—manual (static) and automatic (dynamic) addressing—are described below. •Manual (static) Addressing - Is ’Manually Configure’ option on Interfaces Parameters page of SPEEDLAN 9200 ConfiguatorEach device connected to the Internet must have its own unique IP address. Also, if a computer is being used as a server, you will assign it a permanent IP address. This enables other computers to connect to it. Static addressing is also beneficial to users that need to maintain a "constant" connection to the Internet. This will enable users to easily access the IP address. •Automatic (dynamic) Addressing - Is ’Use DHCP’ option on Interface Parameters page of the SPEEDLAN 9200 Configurator.A DHCP (Dynamic Host Configuration Protocol) server assigns the IP address to each computer as the computer connects to the network. If a computer moves to a new network (i.e., great for temporary employees or mobile users), it must be assigned a new IP address for that network. DHCP can be used to manage these assignments automatically. DHCP is described in further detail below. What is DHCP? Dynamic Host Configuration Protocol (DHCP) allows network administrators to assign dynamic IP addresses for the period of time needed to connect to the Internet. Think of DHCP as leasing an apartment. A prospective tenant may not need to live in an apartment for two years, maybe just a year. Therefore, the tenant will only sign a one-year lease
Part # 34357-MNL Rev. B SPEEDLAN 9200 User Guide 9-8agreement. For example, each time a computer is set up to connect to the Internet, the network administrator uses DHCP to automatically assign the computer a unique IP address. That computer will give up its IP address when it is no longer needed (when the lease has ended) allowing new a computer (or a new tenant) on the same network to use it. This benefits educational and corporate settings where users often log on to different computers. In this case more IP addresses outnumber computers because you can quickly reconfigure the network if needed from a centralized location. Servers that utilize DHCP resolve security issues, costly IP addressing services, and compatibility problems. DHCP is an alternative to BOOTP, which reduces the agony of assigning static IP addresses and also provides advanced configuration options. Note: The figure on the next page may help you understand how DHCP assigns and IP address. Figure of DHCP Addressing Figure 9-2: DHCP client and server1The client asks DHCP server for IP address and configuration if needed. 2The DHCP server assigns an available IP address to client.
SPEEDLAN 9200 User Guide Part # 34357-MNL Rev. B 9-9 3The client takes IP address from DHCP server and requests any additional configuration needed. 4DHCP server confirms IP address and configuration. What is NAT? Network Address Translation (NAT) is the conversion of an Internet Protocol address (IP address) used within one network to a different IP address within another network. One network is designated the inside network and the other is the outside network. Network Address Translation (NAT) occurs when there is a translation among an Internet Protocol (IP address) used within one network (designated as inside network) to a different IP addresses within another network (designated as outside network). Network Address Translators (NATs) allow companies to decrease the number of global IP addresses. This enables companies to communicate with other devices on the Internet with a single global IP address (or more than one IP address). For example, a company can provide its clients with one IP address, allowing access to the company's firewall only. This IP address is not a "real" address on the company's internal network, but it is successfully translated to the correct IP location through NAT (i.e., NAT router). Therefore, the company controls access through firewalls and provides multiple IP addresses to outside customers without excessive limited resources, or "global" Internet IP protocols. NAPT What differentiates NAPT from NAT? NAPT (or Network Address Port Translation) not only translates the IP address but also the transport layer port. Thus, if an inbound packet was addressed to a web server port on 80, the NAPT device would translate and pass to the packet to the private network's web server. Without port translation, the NAT device has no means of knowing which host in the private network can pass packets to other devices. For an example see, Diagram of Incoming NAT, page 9-12.
Part # 34357-MNL Rev. B SPEEDLAN 9200 User Guide 9-10Diagram of Outgoing NATFigure 9-3: Outgoing NATAs the packet is transmitted from the private network (in Building B) across the public network (public address in Building A and the Internet), the packet will be re-addressed as 192.0.2.3 (public address). When the packet returns to Building B, the packet will be re-addressed to the IP address of the private network by using the MAC address contained in the header to identify the destination.

For example, if a web server (IP Address 10.0.0.3) is being hosted on a private network in Building B, you can create a pair that will specify that all requests on the public IP address, Port 80, be forwarded to IP Address 10.0.0.3 on the private IP address, Port 80.Inbound Port 80 request is re-addressedto Private address 10.0.0.3.

Part # 34357-MNL Rev. B SPEEDLAN 9200 User Guide 9-12Basics of RoutingA router connects two or more networks or subnetworks together and decides which direction it should send each packet. A router is typically a gateway (where one network meets another). A router operates at the Network Layer of the OSI model. This means a router sends information based on the packet's IP address instead of the Ethernet (MAC) address (as in bridging).Routing protocols use special metric algorithms when determining the best path for a packet to travel. All of this information is stored in a routing table. Some of this information includes hop count and destination information. The routing table also stores when the receiver gets the packet and lets the sender know that is was received.Note: For more information about routing, see www.whatis.com, http://www.techweb.com/encyclopedia/, http://www.computeruser.com/resources/dictionary/dictionary.html, or search for "basics of routing" on the World Wide Web.

Chapter 10Public Safety Band
Part # 34357-MNL Rev. B SPEEDLAN 9200 User Guide 10-2Background Information on the 4.9 GHz Public Safety Band (PSB)The Federal Communication Commission (FCC) has allocated 50 megahertz (MHz) of spectrum in the 4940-4990 MHz band (4.9 GHz band) for fixed and mobile wireless data communications, designating the band for use in support of public safety (Public Safety Band, PSB). Specifically, the Commission adopted two emission masks limiting interference potential for the band, one for low power and one for high-power operations. These changes will allow public safety licensees to leverage commercial off-the-shelf (COTS) technologies available for the U-NII and ITS frequency bands. The FCC action allows for a nationwide focus on homeland security, and will ensure that all state and federal agencies possess the required commu-nications resources to adequately protect the public. This allocation will provide public safety users the additional spectrum required to support broadband applications such as high-speed data transitions and video over wireless, which in turn enhances local area networks for incident monitoring and supervision. The spectrum can also be used to support the dispatch operations communications as well as safety vehicle communications. Public safety agencies will be able to implement on-scene wireless networks for streaming video, rapid Internet and database access, and trans-fers of large files such as maps, building layouts, medical files, and missing person images. It also allows these agencies to establish temporary or permanent links to support surveillance operations. This allocation gives every jurisdiction in the country access to spectrum for deployable, interoperable, broadband commu-nications.The spirit behind the creation of the band was to allow the public safety organizations access to inex-pensive hardware already available for the ISM bands, but in a section of the spectrum that is not available to the general public.Key Facts of the 4.9 GHz PSB band• The FCC allocates the 4.9 GHz band for fixed and mobile communication.• The FCC designates the 4.9 GHz band for use solely in the support of public safety encompassing the protection of life, health and property• Users must be a state or local government entity or non-government entity authorized by a local or state public safety entity.• Provide services that are not commercially available to the public.• The FCC rules allow a maximum total power output of 33 dBm (2 W) per channel and a maximum antenna gain of 9 dBi for a maximum EIRP of 42 dBm.• Public safety agencies can apply for licenses to use the spectrum within their areas of jurisdiction. • The FCC rules permit broadband mobile operations, fixed hotspot use and temporary fixed links. • Fixed point-to-point operations are also permitted but this use requires a separate license from the FCC for each station.• The FCC rules prohibit use for services that are made commercially available to the public• The new looser emissions mask is designed to allow users to utilize off the shelf technology to signifi-cantly reduce cost and time
SPEEDLAN 9200 User Guide Part # 34357-MNL Rev. B 10-3 Eligibility for 4.9 GHz PSB UseAll state and local government entities that provide public safety services, this is defined as their primary focus being the protection for the safety of life, health, or property; are eligible to apply for a 4.9-GHz license. The control of the licensing is being managed at the state and local level to facilitate priority and availability of the 4.9 GHz band. Entities that do not meet these eligibility requirements, but that provide services in support of public safety, such as private infrastructure companies, can negotiate sharing agree-ments with license holders. 4.9 GHz PSB Frequency Band PlanThe 4.9 GHz band ranges from 4940.5-4989.5 MHz and can be segregated out using 1, 5, 10, 15, and 20 MHz of bandwidth. 4.9 GHz PSB Licensing RequirementsA 4.9 GHz band license gives the licensee authority to operate on any authorized channel in this band within the applicant's legal jurisdiction such as city, county, or state. The 4.9 GHz band is shared by all licensees, who must coordinate their usage of the band with other licensees within their areas of authority. The 4.9 GHz licenses are granted for a 10-year term. The license gives authority to construct and operate:• Any number of base stations anywhere within the area authorized by the license• Base and mobile units, including portable and handheld unitsA 4940-4990 MHz band license does not give the licensee authority to operate permanent fixed point-to-point stations. Licensees choosing to operate such fixed stations must license them individually on a site-by-site basis. Such fixed operation will be authorized only on a secondary, non-interference basis to base, mobile and temporary fixed operations.4.9 GHz PSB Peak Power LimitsThe transmitting power of radios operating in the 4940-4990 MHz band must not exceed the following max-imum limits:Channel Bandwidth in MHz Class A peak output power in dBm Class B peak output power in dBm120 7527 1410 30 1715 31.8 18.820 33 20
Part # 34357-MNL Rev. B SPEEDLAN 9200 User Guide 10-44.9 GHz PSB Emission MaskThe FCC has adopted two emission masks for use in the 4.9 GHz band. The first being DSRC-A, is a mask strictly for low-power applications. The second being the DSRC-C mask is strictly for high-power applica-tions. The DSRC-A mask is identical to the mask defined in the widely used 802.11Wi-Fi standard, which is most commonly used in-home wireless LANs and consumer hotspots. These 802.11 devices are readily available for purchase and significantly reduce cost and time to market for wireless deployments.

Glossary for Standard DataCommunications
Part # 34357-MNL Rev. B SPEEDLAN 9200 User Guide Glossary-2Glossary for Standard Data CommunicationsAdvanced Encryption Standard (AES)Advanced Encryption Standard was adopted by the National Institute of Standards and Technology in October of 2000. AES presents a new level in computer networking security, especially important in wireless communications because wireless circuits are easier to tap than their hard-wired counterparts. AES is more dif-ficult to crack than its predecessor Data Encryption Standard. SPEEDLAN 9200 products use an AES128-bit encryption key. Address Resolution Protocol (ARP)ARP is the abbreviation for Address Resolution Protocol, which maps an IP address to a machine's hardware address. Network administrators use ARP to locate systems on the LAN that are configured with incorrect IP addresses.AlignmentIn order to create a successful link, all related equipment should be associated to its respective attachments or equipment.Amplitude The magnitude of a waveform when measured from the mid-point to the peak of the wave.AnalogA signal in the form of a continuously varying quantity such as voltage, frequency or phase.AntennaDevice used to concentrate and direct the energy of a signal into a tight beam.

It is dimensionless and is instead referenced to a certain level.DiffractionThe distortion of a wave as it is partially obstructed by an object in its path.Digital Signal Processor (DSP)A specialized computer chip designed to perform speedy and complex operations on digitized waveforms.Direct Sequence (DS)A type of spreading technique that multiplies a higher rate PN code to the signal in order to spread the energy of the narrow band signal over a much wider bandwidth for transmission. Direct Sequence Speed Spectrum (DSSS)DSSS may be seen as the result of two processes. Data is multiplied with a higher rate digital sequence (spread-ing code). The sequence has many “chips” for every data bit.

Part # 34357-MNL Rev. B SPEEDLAN 9200 User Guide Glossary-61. Height above sea level. 2. The vertical angle in degrees between the ground and the direction the antenna is pointed.Encryption The method of converting data into a form that cannot be understood by unauthorized people. Encryption is very important when using wireless communication because wireless circuits are easier to tap into than wired circuits. There is also strong encryption, which means ciphers are used to make uncoding the signal almost impossible, unless you have the decryption keys.ESDElectro-Static Discharge happens when there is a transfer between objects at diverse voltages.EthernetThis is the most popular physical layer LAN technology in use today. Other LAN types include Token Ring, Fast Ethernet, Fiber Distributed Data Interface (FDDI), Asynchronous Transfer Mode (ATM) and Local Talk. Ether-net is popular because it strikes a good balance between speed, cost and ease of installation. Ethernet SwitchThis device helps expand the Ethernet network. LAN switches can link four, six, ten or more networks together, and have two basic architectures. This switch “cuts through” and “stores and forwards” as well. This technique takes more time to examine the entire packet, but it allows the switch to catch certain packet errors and keep them from propagating through the network. A switch also operates between the DataLink and Network Layer of the OSI model. It reads the MAC address and will either bridge it to the Physical Layer or route to the Network Layer.Fade MarginThe difference between the receiver signal input level and the receiver sensitivity. Fade margin is usuallyconsidered the safety factor allowing the system to remain operating under additional forms of attenuation.FadingThe loss of signal strength due to changes in the atmosphere.

SPEEDLAN 9200 User Guide Part # 34357-MNL Rev. B Glossary-9Institute of Electrical and Electronics Engineers (IEEE)A membership organization that includes engineers, scientists and students in electronics and allied fields. It was founded in 1963.InterfaceThe standard signal for connecting a microwave system to the connecting equipment.InterferenceUnwanted signals that cause performance degradation or loss of information.InternetThis is a system of linked networks that are worldwide in scope and facilitates data communicate service such as remote login, file transfer, electronic mail, the World Wide Web and newsgroups. With the meteoric rise of demand for connectivity, the Internet has become the communications highway for millions of users. The Internet was initially restricted to military and academic institutions in its infancy, but now it is a full-fledged information channel for any and all forms of information and commerce. Internet web sites now provide personal, educational, political and economic resources to every cornet of the planet.IP AddressThis address tells the network how to locate the computers or network equipment connected to it. IP addresses are given so each computer or equipment on the network contains a unique address. There are two methods used when assigning an IP address:• Automatic (dynamic) AddressingA DHCP (Dynamic Host Configuration Protocol) server assigns the IP address to each computer as the computer connects to the network. If a computer moves to a new network (i.e., great for temporary employees or mobile users), it must be assigned a new IP address for that network. DHCP can be used to manage these assignments automatically. •Manual (static) AddressingEach device connected to the Internet must have its own unique IP address. Also, if a computer is being used as a server, you will assign it a permanent IP address. This enables other computers to connect to it. Static addressing is also beneficial to users that need to maintain a "constant" connection to the Internet. This will enable users to easily access the IP address.ISM (Industrial, Scientific, and Medical Bands)Ranges are 900 to 928 MHz; 2.4 to 2.4835 GHz; and 5.725 to 5.85 GHz. The FCC for unlicensed use allocated these bands with a restriction on the output power.IsotropicUniform in all directions.

The most common proto-col to retrieve the information associated to a specific object is SNMP.MDS (RIP2 MD5 Authentication) When RIP2 is used with an authentication algorithm, such as MD5, network security is increased since the desti-nation receiving the RIP packet knows that it was generated by a reliable source (i.e., the actual sender of the packet). RIP2-MD5 authentication transmits the output of the authentication algorithm rather than the RIP2 authentication key. Therefore, the RIP2 authentication key is never transmitted over the network and cannot be heard by other routers. This means a router can determine exactly who sent the message and not assume which router sent it. Mean Time Between Failure (MTBF)This is defined by a specific set of calculations. The formula of the system longevity is based on the thermal, elec-trical and environmental stresses on each component. MHz (MegaHertz)Millions of Hertz.ModulationThe process of varying characteristics of a carrier signal to represent changes in the transmitted information.MOdulator-DEModulator (MODEM)A device that converts a digital signal to analog, or vice versa, and is used to transfer data between computers over communications lines.Mb/sMillion of samples per second.Multi-path fading The condition in which the “true” signal from an antenna reflects off an object (usually the ground) and, as a

RF Signal LevelThe strength of the power received by the RF Unit from the antenna.Routing Information Protocol (RIP)RIP determines a route based on the fewest hop count between the source and destination. RIP, a distance vector protocol, routinely sends broadcasting to its neighboring nodes. There are different classes of RIP:RouterThis device filters out network traffic by specific protocol rather than by packet address. This device operates at the Network layer of the OSI model. Routers also divide networks logically instead of physically. An IP router can divide a network into various subnets so that only traffic designated for particular IP addresses can pass between segments. Network speed often increases due to this type of intelligent forwarding. Such filtering takes more time than exercised in a switch or bridge, which only looks at the Ethernet address.

SMTP is a TCP/IP protocol, and it defines themessage format and message transfer agent, which is used to store and forward the mail. Spread Spectrum Technology (SST)A method of encoding (with a PN code) a digital signal in a transmitter so as to spread it over a wide range of frequencies so that the average signal power is close to the noise floor. The same code is known to the receiver and is used to decode the signal. Keeping the code secret provides communications security.StarA topology (in the K2 polling protocol category) that includes point-to-point or point-to-multipoint activity, as long as those routers are within line-of-sight of each other.Subnet maskThis term allows you to mask section(s) (depending on the class specified) of the octets in the network address. Each octet used in the subnet mask is assigned to a data link. The leftover octet(s) are assigned to the remaining nodes.
SPEEDLAN 9200 User Guide Part # 34357-MNL Rev. B Glossary-17SubnetThis term allows you to create multiple networks within one Class A, B, or C network. Each data link (octet) con-tains its own unique identifier also known as the subnet. Also, each node on the same data link must belong on the same subnet as well.Symbol ThresholdAfter a signal has been acquired, the acquisition algorithm in the spread-spectrum chip continues to run a cross-correlation between the expected PN sequence and the received signal, but now uses the Symbol Threshold for comparison.

Appendix E -Firmware HistoryThis appendix lists history of any prior firmware notes.
Part # 34357-MNL Rev. B SPEEDLAN 9200 User Guide E-2Version 2.2.0New Features:4.9 GHz PSB: Adds the capability to transmit Radio Frequency signals in the Public Safety Band of 4.9 GHz as per FCC Rules part 90, Subpart Y.Field Upgradeable: Adds the ability to upgrade the router, via software, to a different model configuration, without physically removing the router from the network. Bug Fixes: None.Known Problems: None.Version 2.1.0New Features: The following new features are added to this release: Stronger Security: adds the support of WPA with TKIP & MIC and WPA2 with AES-CCMP which include a dynamic key management system. The new design also allows “Per Group” encoding of unicast and multicast packets as well as simultaneous and independent “Per Link” encoding of unicast packets in each link in the network. Star or PMP Network Topology: adds the support of new SpeedLAN 9203 model, which can be configured as a STAR Base or as a CPE [Customer Premise Equipment]. It creates a bona fide PMP product in which the parameters of the network are easily controllable from the Base Station. Bandwidth Limiting: adds the support to allow the user to control the bandwidth use of each SpeedLAN unit in a mesh or a star network. This feature allows controlling the amount of traffic from the Wireless Port to the Ethernet Port and also from the Ethernet Port to the Wireless Port with independent parameters. ToS [Type of Service]: adds the support of ToS which provides a comprehensive traffic classification scheme and the choice of 8 levels of priority selection for each classification. Tagged traffic is classified by its DiffServ Code Point, and untagged traffic by other set of properties like for example the protocol and IP port. Configuration File Upload/Download: adds the support of configuration file upload/download to simplify the process of unit configuration that generally requires a good degree of expertise and can lead to errors.
SPEEDLAN 9200 User Guide Part # 34357-MNL Rev. B E-3 System Log: adds the configurable Sys Log capability to improve troubleshooting and general network management. Ethernet Port DHCP Client: replaces DHCP Client “PUMP” with ISC dhclient. The ISC dhclient corrects: 1) Non-zero Source IP address and, 2) “Do Not Fragment” bit problems in the IP header of DHCP Request packet generated by “PUMP”. The ISC dhclient also allows SpeedLAN unit to specify: 1) Subnet Mask, 2) Broadcast address, 3) Time-offset, 3) Routers, 4) Domain-name, 5) Domain-name-server, and 6) Host-name options in the DHCP Request packet. Wireless Port DCHP Server: adds the Server support to the Wireless Port to assign IP addresses to mobile mesh clients. License Control: adds the license control to allow a SpeedLAN unit to control the communication with a certain number of mobile clients that associate to it. The license is provided by uploading to a given unit a license file specific for that unit. Bug Fixes: 1) The problem in controlling the XMT power settings is fixed; the functions to handle the Calibration Table stored on Radio card is incorporated in V2.1.0. Known Problems: NoneVersion 1.0.8Bug Fixes:1This release fixes the problem that when DHCP Client is unable to obtain an IP address from the DHCP Server, or if a DHCP Server is just not available, then the Ethernet interface goes into “not functioning” mode. IPRecover then does not see the unit.2Also fixes the problem that the ACK timeout interval cannot support the link dis-tance, which is longer than 2.4 miles in 11a mode, 4.6 miles in 11b mode, and 4.1 miles in 11g mode.Known Problems: Same status as previous release minus the bug fixes indicated above.Version 1.0.6Bug Fixes:
Part # 34357-MNL Rev. B SPEEDLAN 9200 User Guide E-4Enlarges ACK and CTS timeout interval to support link with longer distance. Known Problems:Cannot fully control the settings of the XMT power; the functions to handle the Calibration Table stored on Radio card are not supported in the HALVersion 1.0.5Bug Fixes: The transmitted/received counters were reported incorrectly under the Wireless Statistics section on the Statistics page. (This page is located under the Diagnostics menu of the SPEEDLAN 9200 Configurator.) For more information, see Interface Statistics, page 3-81.Known Problems: The transmit power exceeds FCC certified power ranges. Version 1.0.4New Features:A new Transmit Rate Adaptation Algorithm allows the radio to transmit unicast packets at the optimum signaling rate. If there are changes, caused by either obstacles or interference in the wireless channel, the rate adaptation algorithm will automatically increase or decrease to an optimum rate, which is selected for each packet by the algorithm based on statistics of recent transmissions. This process creates reliable data transmission at the fastest possible rate.Bug Fixes:•There were collisions between broadcast packets (Mesh Neighbor Discovery Packet) when the network had hidden nodes, which caused some links to be unstable.•When the link had errors, the Signaling Rate dropped to the lowest enabled rate, and was slow to increase.•In few instances, the unit hung up when the link experienced heavy interference. This problem occurred when the unit was in 2.4 GHz DSSS mode.Known Issues:The transmit power exceeds FCC certified power ranges.
SPEEDLAN 9200 User Guide Part # 34357-MNL Rev. B E-5 Beta Version 1.0.3 Bug Fixes:•Unit loses connectivity via the Ethernet port (Version 1.0.1): Unit can be accessed via the RF port but cannot be seen via its Ethernet interface. A link light is seen on the computer. The Configurator command shows that the Ethernet interface is receiving no traffic. •Host route deleted by unit (Version 1.0.1): Under certain rare circumstances, a static host route was deleted from the routing table. •Auto-fallback kicks in with fixed rates: (Version 1.0.1): Unit does not report the Signaling Rate change to SPEEDView.Known Issues:•There are collisions between broadcast packets (Mesh Neighbor Discovery Packet) when the network has hidden nodes, which causes some links to be unstable.•When the link has errors, the Signaling Rate drops to the lowest enabled rate, and is slow to increase.•In few instances, the unit hangs up when the link is heavily interferenced. This problem occurs when the unit is in 2.4 GHz DSSS mode. Documentation Fixes•Removed SPEEDLAN 9205 references. Refer to Chapter 2, beginning on SPEEDLAN 9200 Hardware, page 2-1 for more information.•In Revision 02 of this User Guide, we stated that the 2.4GHz operates on a non-interference basis with other devices operating at the 2.4GHz frequency when using the 17dBi directional grid antenna. The correction is that it should read, "...when using the 18dBi directional antenna." Also, the Declaration of Confor-mity for RF Exposure Statement has been revised. Please see Declaration of Conformity for RF Exposure, page 2-3 for more information. •2.4GHz OFDM and DSSS references have been added to this User Guide. This means that the preamble setting is now functional. •The List of MIBs supported by SPEEDLAN 9200 table has been corrected to dis-play the right version.
