Description 22 LIBRA 5816 Series User ManualLIBRA 5816 System Components Base Station (BS) Equipment The BS controls communication within the wireless network and is the main access point to the Ethernet. The access point communicates with the SS’s in the system to provide each SS with Access to the main network (ie Ethernet). The access point is typically located at a distance away from the SS that will provide adequate radio signal strength for the specified data rates. The Base Station is responsible for any Subscriber Station (SS) data management functions. The LIBRA 5816 BS consists of three parts: " BS radio unit, " Ethernet Power Inserter with CAT-5 cable (bought separately) and weatherproofing kit(included), and " the External Antenna and cable (both bought separately) " LIBRA 5816 BS– The BS is the main piece of radio equipment. It is designed for outdoor installation but can also be installed indoors if needed. The BS is equipped with an N-type (F) RF connector so that the external antenna can be connected to it. Thus many different types of base stations can be deployed using sectoral, omni or other specialized antennas. " Ethernet Power Inserter– This piece of equipment is a small box that connects between the SS and the P.C. This box also provides power for the BS equipment to run. A CAT-5 outdoor cable is
Description 23 LIBRA 5816 Series User Manualused to connect the Power inserter to the BS. The weatherproofing kit is used with standard RJ-45 connector to ensure reliable connection for outdoor systems. " Antenna and Cable– In order to accommodate different frequency re-use plans and scalability of the base stations the BS is designed to be used with an external antenna. Antennas and cables are selected by the user based on the network requirements. Subscriber Station (SS) Equipment The Subscriber Station connects customers to the Base Station via a wireless link. The link enables customers to communicate with other users of the wireless network and the Ethernet. Subscriber Station has two parts: 1) SS radio unit and 2) Ethernet Power Inserter with CAT-5 cable (bought separately) and weatherproofing kit (included). " LIBRA 5816 SS– The SS is the main piece of equipment that would normally be installed outdoors (indoor installation is permitted when feasible) The SS contains all of the necessary radio equipment to provide a high-speed wireless link. The SS also has an integral antenna such that no RF cables are required for a typical installation. " Ethernet Power Inserter– This piece of equipment is a small box that connects between the SS and the P.C. This box also provides power for the SS equipment to run. A CAT-5 outdoor cable is used to connect the Power Inserter to the SS. The weatherproofing kit is used with standard RJ-45 connector to ensure reliable connection for outdoor systems. Wireless network activity focuses on the BS, which is both the main access point to the Ethernet (LAN or WAN) and the destination for SS-originated communications (SSs do not communicate directly with other SSs—they communicate only via the BS). SSs complete the customer-end of a wireless link. Long Range Subscriber Station (LSS) Equipment The Long Range Subscriber Station (LSS) also connects customers to the BS via a wireless link. The LSS enables the customer to reach longer ranges by allowing the connection to a higher gain external antenna. It can also be used for indoor installation of the units should severe weather conditions require it. The antenna is then mounted outdoors and connected via appropriate RF cables to the unit. One other alternative which customers may want to consider is to use lower gain

The LIBRA 5816 LSS consists of three parts: 1) LSS, 2) Ethernet Power Inserter with CAT-5 cable (bought separately) and weatherproofing kit (included), and 3) the External Antenna and cable (both bought separately). " LIBRA 5816 LSS– The LSS is the main piece of equipment. It is designed for outdoor installation but can also be installed indoors if needed. The LSS is equipped with an N-type connector so that the external antenna can be connected to it. Thus the range of the system can be significantly increased by use of higher gain antennas. Also, in situations where very severe conditions may be encountered outdoors the LSS can be installed indoors with cabling to the antenna outside. " Ethernet Power Inserter– This piece of equipment is a small box that connects between the LSS and the P.C. This box also provides power for the LSS equipment to run. A CAT-5 outdoor cable is used to connect the Power inserter to the LSS. The weatherproofing kit is used with standard RJ-45 connector to ensure reliable connection for outdoor systems.

Troubleshooting 74 LIBRA 5816 Series User ManualTroubleshooting General principles Proper management and maintenance can prevent the occurrence of many problems and discover and handle problems as early as possible before problems become serious. The following methods are recommended for regular maintenance. " Establish regular maintenance log rules. " Keep detailed records of failure points, symptoms, occurrence time and treatment methods. " Follow up failure treatment results. " Conduct planned link tests on a regular basis. " Check the installation tower, antenna, ODU, cables and adapters on a regular basis, especially after a bad weather. " Test the system performance on a regular basis, as environment changes, normal wear and cracks of the device may have an adverse impact on the system performance. " Keep the integrity of system design when adding or changing a system. When adding a new unit into the system, revise the network plan again to prevent problems. For example, installing an extra antenna at the same place improperly will lead to self-interference of the system. " Save the records of all changes, especially relevant files of the adding unit, software and hardware change, configuration and setting changes, as configuration error often leads to other problems. Compare current record files with the original record files to analyze and address failures. Considerations on Regular Maintenance and Failure Treatment 1. Network Integrity: ensuring the integrity of the network is vital to the network performance and reliability. If the network design is changed, the network operation will be affected. Fully acquaint yourself with recent change of the network. 2. RF Link Quality: data communication depends firstly on good RF link. If you set up and maintain high-quality RF link, you can ensure these links to bear high-speed data flow. If the quality of the RF link deteriorates, as a consequence, the quality of data communications will deteriorate too. 3. Transmission Module: the module consists of three parts, namely, ODU generating signals; antenna feed line including the cable, connector and oscillatory interference suppressor, antenna. The faulty device may be found out through tests and replacements. " To identify the state of the ODU unit, you may check the operating condition of the device on a regular basis and observe its changes in RSSI value and Cinr value; " To identify the state of the antenna feed line, you may use the integrated testing equipment to test the properties of cables, connector and lightning arrester and replace parts when necessary. " To identify the state of the antenna, you may use the integrated testing equipment to test the antenna and replace the antenna when necessary. 4. Proper Unit Configuration: the unit shall be properly configured as per the requirements of the network plan. A configuration error may lead to communication failure or poor communication performance. Adding a new unit in the system or making other changes to the system may need to change the configuration. 
