1 In troduc tion to GX S ys tem MobileAccessGX offers a scalable, cost-effective 20/40W (43/46dBm) high power remote outdoor coverage solution for Corning MobileAccess Distributed Antenna Systems (DAS).
1.1 Features and Capabilities Multi-Frequency/Multi-Service RF Transport Platform: Accommodates GSM, UMTS, HSPA, LTE, EDGE, EV-DO, and more. Three model-dependent bands per enclosure. Scalable: Expandable tri-band to up to six bands. MIMO support: 2x2 MIMO configuration for LTE700, AWS and UMTS bands Cost-Effective Higher Power: Optimizes and reduces the number of antennas required to cover open and outdoor areas by offering 43dBm or 46dBm (GX-20/40) composite power per frequency band.
1.2 System Architecture MobileAccessGX provides a complete solution consisting of GX remote units at the remote locations, and head-end elements, which are shared with any existing or new MA1000/MA2000 deployment. In the downlink, at the head-end, the BTS or BDA signal is conditioned by the RIU, ensuring a constant RF level.
1.2.1 Signal Path 1.2.1.1 SISO Signal Path On the DL, combined signals up to tri-band from the OCH converted into optical signals. Then the optical signals are transmitted to the RU via optical fiber. The Optical TX/RX Module of RU converts the DL optical signals into RF signals. After filtering signal for each band and amplification, the signals are transmitted at the output port (700MHz/CELL850/PCS/AWS) to the service antenna.
350 OCH element (that is connected to the controller). Thus, the controller monitors views and manages the GX via the OCH to which the GX is connected. The following shows the Config(uration) tab of the selected GX unit. The system configuration and management is described in Chapter 4.
1.4 GX Unit Interfaces All of the GX interfaces are located externally on the underside of the unit (facing down when unit is mounted). The unit interfaces include the RF, power and optical link connectors.
The following tables provide a description of the GX LEDs. LED Description RUN GREEN – Power on ALM OFF – Normal operation RED - Fault FSK (Frequency Shift Keying) Flashing 1s – Normal FSK OFF – Fault in FSK operation Table 1-2.
2 S ys tem Ins talla tion This chapter describes the installation procedure for the MobileAccessGX Remote Units. 2.1 2.1.1 Site Considerations The distance between the GX service antenna and the coverage area should correspond to LOS (Line of Sight) requirements for maximum coverage area. The maximum fiber path loss is 6dB. The system delay of the optical system must be taken into consideration when there are neighboring BTS sites overlapping in coverage.
2.1.5 Cable Routing Ensure all cables, e.g. power cable, feeder cable, optic fiber, commissioning cable, connecting are properly routed and secured so that they are not damaged. 2.1.6 Manual Handling During transportation and installation, take necessary handling precautions to avoid potential physical injury to the installation personnel and the equipment. 2.2 Installation Requirements 2.3 Working space available for installation and maintenance for each mounting arrangement.

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.
Appendix B: Ordering Information Fiber Optic Rules Either single mode or multimode fiber can be used with MobileAccess2000M products, while MobileAccess2000 products can only be used with single mode fiber. Only Multimode fiber, 50/125 or 62.5/125um complying with ANSI/TIA/EIA-568-B series, EN50173-1 or ISO/IEC 11801 can be used. The fiber length can be up to 300 meters assuming the following qualifications: All fiber in a given length of fiber must be of the same core diameter.
Appendix B: Ordering Information 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 pl aced 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).
Appendix B: Ordering Information Circuit Breakers Install fuse protections for the system according to the following criteria: The following system elements require external fuse protection: RIUs, BUs, and SC450 Controllers. Referring to Table 4-2, calculate the required fuse protection. Example: a set of three elements consisting of a BU, RIU and SC-450 controller requires a 2A circuit breaker.
Appendix B: Ordering Information The following figure illustrates fiber optic routing to Remote Cabinets. Figure 4-7. Illustration of Fiber Optic Routing For remote power supply configuration - cable bundles are routed from the main communication room and individual wire pairs are terminated into the power feed of individual units. By providing power from a single distribution point, maintenance can be reduced and UPS backup can be easily provided.
