MA 1000 Installation and Configuration Guide 20 2.2 Radio Interface Unit (RIU) The RIU is an operator dedicated unit that interfaces to up to three BTS sources and automatically adjusts the signal output according to changing environmental conditions in order to provide optimal coverage for the site. The RIU is remotely monitored and managed. Each RIU can support up to three BTS Conditioner (BTSC) sub-modules, where each sub-module provides interface to a BTS or BDA of the same type of service. Each RIU can be connected to four 8-port Base Units (real panel connections) or to eight 4-port Base Units. Additional BUs can be supported by using splitters and combiners connected to the front panel Expansion connectors. The following figures shows an RIU with three BTSC sub-modules. Figure 2-11. RIU Note: All connections are via RG223 coax cables with 1/2" N-type male connectors ATTENTION The RIU is factory set to 0dB gain on the uplink and downlink. In order to operate properly, an ADJUSTMENT process is required in the field. Any unused input and output connectors MUST be terminated with 50 ohms – otherwise the ADJUSMENT procedure results may be affected.

MA 1000 Installation and Configuration Guide 22 2.2.1.2 RIU Rear Panel The rear-panel provides all the connections on the BTS side and on the BU side as well as connections to the MobileAccess 410/430 controller and the power connection. Two types of BTS side connections are available for each BTS conditioner: simplex and duplex. Figure 2-13. RIU Rear Panel showing the RF Connection 2.3 MA Base Units The BUs (Base Units) perform RF to optical conversion of the signal on the BTS/BDA side. Each can support up to two services (provided by the same operator). Two models of MA BUs are available: four-port unit – supporting four RHUs, and eight-port unit supporting up to eight RHUs. The RHU models correspond to the services supplied through the BUs. The BU (and all the corresponding remote units) may be remotely monitored and managed via the MA NMS (Network Management System). The BUs are usually installed in the telecom room adjacent to the BTS/BDA signal source. RF ports on the rear panel provide interface to the BTS side (through connection to RIU or passive interface), while optic ports on the front panel provide interface to the RHUs (Remote Units). This following sections describe the MA BU front and rear panels, including indicators and connectors.

27 33 SSiittee PPrreeppaarraattiioonn 3.1 Infrastructure Preparation This following installation rules are based on the assumption that site survey and installation planning (including power requirements) have been completed. 3.2 Installation Requirements The infrastructure preparation consists of two main phases: A. Floor Planning: Planning the distribution of the antennas on each floor to provide the required coverage. B. Telecom Closet Planning: Planning the layout of the devices and cables in the telecom closet or shaft. This includes the MA 850, 802.11 Access Points, cabling and other voice service distribution systems that are relevant to the specific installation. 3.3 Coaxial Cable Connections 3.3.1 General Cable Installation Procedures Observe the general cable installation procedures that meet with the building codes in your area. The building code requires that all cabling be installed above ceiling level (where applicable). Each length of cable from the risers to each antenna must be concealed above ceiling. The cable must be properly supported and maintained straight using tie-wraps, cable trays and clamps or hangers every 10 feet (where practical above ceiling level). Where this is not practical, the following should be observed: • The minimum bending radius of the supplied ½” coax cable should be 7”. • Cable that is kinked or has a bending radius smaller than 7” must be replaced. • Cable runs that span less than two floors should be secured to suitably located mechanical structures. • The cables should be supported only from the building structure.
MA 1000 Installation and Configuration Guide 28 3.3.2 Fiber Optic Rules • Use only single mode fiber for indoor applications. • Use only 8-degree SC/APC connectors (green color). • Use only fusion splice for connecting two fibers. • Use minimum splicing/connectors to achieve minimum losses on the fibers (<0.5dB). • Use precaution while installing, bending, or connecting fiber optic cables. • Use an optical power meter and OTDR for checking the fiber optic cables. • Make sure the environment is clean while connecting/splicing fiber optic cables. • All fiber optic connections should be cleaned prior to attaching to termination points using a dry cleaning device (i.e. Cletop or equivalent). • Fiber connector protective caps should be installed on all non-terminated fibers and removed just before they are terminated. • Verify the Fiber Optic connections. You may use the Optical Test Procedure described at the end of this manual. • Pay special attention while connecting the SC/APC connectors - you must hear the “click” when the connection is made. 3.3.3 RF Rules • Use coax RG223, 50ohm, male-to-male N-type for RF connections from the BUs to the BTS/RBS and to the RIU. • When using the MobileAccess™ system in an environment in which other indoor coverage systems are installed, it is recommended (where possible) that the antennas are placed at least two meters apart • When bending coax cables, verify that the bending radius does not exceed the coax specifications. • Use wideband antennas supporting a range of 800Mhz to 2500Mhz • Use a VSWR meter (i.e. Site Master or equivalent) for checking coax cables, including the antennas. (<2). The VSWR must be measured prior to terminating the RHUs in the remote communication rooms • Terminate all unused RHU and RIU ports with a 50 ohm load
MA 1000 Installation and Configuration Guide 29 3.3.4 Coax Cable Lengths and Losses Use coax ½”, 50ohm, male-to-male N-type, (6-7dB for 1Ghz, 11dB for 2Ghz) for connecting to RHU and RHU ports.
