1 IInnttrroodduuccttiioonn ttoo MMAA WWiiMMAAXX SSyysstteemm MobileAccess WiMAX Indoor Coverage Solution provides a complete, cost effective, scalable indoor coverage solution for up to two MIMO WiMAX. The MA-WiMAX solution enables distributing signals from a WiMAX BTS located at a central location over fiber optic connections to remote locations (different floors or areas) throughout the building infrastructure. The solution can be used as stand-alone - providing only WiMAX coverage via a dedicated antenna infrastructure, or in conjunction with MA-1000 or MA-2000 MobileAccess systems – combining WiMAX with other wireless services for distribution over a common antenna infrastructure. MA WiMAX system provides a truly integrated solution offering a combined services approach to distribute WiMAX and cellular/PCS through a single antenna infrastructure while maintaining a reliable application independent environment. The following block diagram illustrates the stand-alone MA WiMAX solution elements: the MA WiMAX front end equipment is installed near the WiMAX BTS. In the downlink, it conditions the signal and converts it to fiber optic for transmission to each remote site over the optic fiber. At each remote site it is reconverted to RF and distributed by two WiMAX antennas. Each MA WiMAX element is set up and monitored through a local connection from a computer running the MCT application.
WiMAX System User Manual MobileAccess WiMAX System User’s Guide 11 Figure 1. MA WiMAX System Architecture Roof
WiMAX System User Manual MobileAccess WiMAX System User’s Guide 12 Features and Capabilities • Supports two WiMAX MIMO • Scalable: Easily expands as needed to cover several million square feet • Enterprise Value: Solution is easily integrated with other wireless applications – opportunity to amortize deployment costs • Reduced Barrier to Entry: Modular design enables pay-as-you-grow model – add sectors and components as needed • End-to-end Management: Proactive management and control maximizes uptime • Local and remote end-to-end monitoring and control through interface to MA 410 controllers • Monitoring at the head-end through interface to MA-RIU 1.1 System Architecture The system is based on front-end elements that condition and convert the BTS WiMAX signal to an optic signal for transmission over single mode fiber optics to the head-end elements, and on head-end elements that reconvert the WiMAX optic signal to RF and distribute it over the antenna infrastructure at that location. In addition, Controllers located at the front-end provide end-to-end remote control and management. The MA WiMAX system can be converged with another MA mobile service indoor distribution systems (such as MA2000, MA1000, etc.), where the systems run in parallel and share some of the same front-end elements and the antenna infrastructure. The MA WiMAX system front end elements are: • MA WiMAX RIU – conditions the RF signal from the BTS to the level required by the Base Unit. Each RIU supports two WiMAX channels (for MIMO) and two base 4 units (for 8 remote units). See section 2.1.1 for unit description. • MA Multi-service Base Unit – converts the WIMAX channels to optic signal for transmission over one set of optical fibers. See section 2.1.2 for unit description. • MA 410 controller – provides management and control functions to all system elements. The Controller is directly connected to the RIU modules and to the BUs. See section 2.1.3 for unit description. Note: The RIU, Base Units and Controller are located at the head-end (i.e. communication room). The WiMAX systems remote location elements are: • WiMAX RHU – located at each remote location, IDF or telecom closet. Performs the optic to RF conversion of the WiMAX signals and provides the interface (power and communications) to the remote antenna unit (RU) via which the signals are distributed. See section 2.2.1 for unit description. • Remote Antenna Unit (RA) – provides final preparation of the WIMAX signals for distribution via the ceiling antenna(s). The RU has three antenna ports to support 2 MIMOs and one passive cellular antenna. See section 2.2.2 for unit description.
WiMAX System User Manual MobileAccess WiMAX System User’s Guide 13 1.2 WiMAX Standalone Solution – Basic System Operation Figure 1-2 shows the architecture of a stand-alone MA WiMAX system. The WiMAX system receives the services from the operator’s BTS converts them to an optical signal and runs them over optic fiber to each remote location. There, the WiMAX RHU reconverts the services to RF and distributes them to WiMAX antennas via the MA Remote Antenna Unit. The latter provides remote control and management to the passive WiMAX antennas. Figure 1-2. Architecture of a basic MA WiMAX system

Figure- 1-3 shows the architecture of an installation supporting the indoor distribution of WiMAX, together with cellular services over a common coax and antenna infrastructure. The figure shows two systems running in parallel: Cellular system along side of a WiMAX system (at the bottom). Both systems received the services from the operator’s BTS or BDA, convert them to an optical signal and run them over optic fiber to each remote location. There, the cellular RHU reconverts the cellular services to RF and the WiMAX RHU converges the cellular and WiMAX services and distributes them to the WiMAX and cellular antennas via the MA Remote Antenna Unit. The latter provides remote control and management to the passive WiMAX and cellular antennas. Figure- 1-3 –Architecture of MA WiMAX System Converged with MA 1000 System Services

General Checks – verifying that all units are operational and that the infrastructure is in tact allowing signals to be transferred between the units. 2. Performing Continuous Wave downlink gain adjustments 3. Performing a Continuous Wave test under each antenna. 4. Commissioning carriers onto the system Each of the above phases will be detailed in the following sections. 4.2 Requirements Testing Equipment/Documentation Required • Signal Generator for generating 2695 MHz • Optical Power meter 1310nm & 1550nm • MobileAccess Documentation • MobileAccess Data Sheets 4.3 General Checks The procedures described in this section are used to verify that all units are operational and that the infrastructure is intact allowing signals to be transferred between the units. Please read the entire document before you attempt to commission a MobileAccess system A summary of all the general checks is given below. Each step is detailed in the following sections. 1. Verify connections. 2. Set up MCT monitoring - from the MCT application, logon to the MA410. 3. Verify the controller clock settings – this enables correctly time stamping any generated events
WiMAX System User Manual MobileAccess WiMAX System User’s Guide 34 4. Verify end-to-end link in the topology tree by ensuring that all RHUs all visible. 5. Set the base line – ensuring that disconnected units are also displayed. 6. Check each RHU DL optical level from the Base Unit and verify the band configuration for the RHU. 7. Check Base Unit Optical Levels from the RHUs. 8. Name each BU, each RHU and each RIU. 4.3.1 Verify Connections 1. Check all RF, Fiber and Power connections before powering-up the units. 2. Apply power (first to the Bus and then to the RHUs) and verify all power and optical link lights are on for the RIU, 410, RHUs and Base Units. Swap between the connections between the To and From fiber ports if the link LED does not light. 3. Remove the fiber connected to each “From” port on the Base Unit(s) and use an Optical Meter to measure the signal. Expected level: >0dBm @ 1310nm. Corrective action: If the signal is not at the expected level, clean all connectors, if problem persists carry out a full sweep of the fiber connection using an Optical Time Domain Reflectometer (OTDR)
