USER MANUAL FOR RA-5700 RA-5700 QI Copyright - refer to title page Page 11 ENU Status : 1-1-2 1 GENERAL INFORMATION The RA-5700 Tri-Band Distributed Antenna System (hereinafter called “RA-5700”) is designed for working on 700MHz, 850MHz and 1900MHz networks. It provides flexible and scalable solution of multi-band, multi-operator coverage extension applications.It is the ideal solution to both indoor and outdoor as well. RA-5700 consists of Master Unit (MU) RA-5700-D and Remote Unit (RU) RA-5700-R. The low signal transmission loss of optical fiber is applicable for long distance transmission. RA-5700 can support the optical transmission of up to 5dB signal transmission loss. It can extend BTS coverage and eliminate blindspot, shadow area and weak-signal area to improve call quality. Main feature:  High output power with high linearity, which supports multiple carrier operation and ensures the signal source is of good quality.  Optical fiber transmission with long distance transition at the most path loss of 5dB.  Local Operation and Maintenance Terminal (OMT): operating status and parameters can be set or monitored by OMT PC locally. And the point-to-point setting and inquiry between MU and RU is realizable through the integrated wireline/wireless modem, which makes it convenient for on-site configuration.  Operation Maintenance Center (OMC): system working parameters and communication configuration can be set or inquired remotely through the integrated Ethernet adaptor. If alarm is generated, the equipment will dial up to OMC automatically in the mode of GPRS.  Build-in Li-ion battery ensures that alarm information can automatically report to OMC in case of equipment power failure.  RU is designed for all-weather outdoor operation - waterproof, damp-proof and omni-sealed.
