Introduction RSN-CDMA-37-C is used to fill out areas in CDMA mobile systems, such as base station fringe areas, business and industrial buildings, etc. RSN-CDMA-37-C receives signals from a base station, amplifies and retransmits the signals to mobile stations. Also it receives, amplifies and retransmits signals in the opposite direction. Both directions are served simultaneously with the following features: „ 65MHz bandwidth service „ Band Selection (5MHz , 10MHz , 15MHz , 20MHz , 5MHz+5MHz , 10MHz+5MHz, 15MHz+5MHz, 20MHz+5MHz, 5MHz+5MHz+5MHz) service „ Roll Offs: 50dBc at 1 MHz outside pass-band The RSN-CDMA-37-C is controlled by powerful microprocessors. Operational status LEDs are visible on the bottom of the repeater. The repeater works with convection cooling without fan because it has a radiator behind the body of RSN-CDMA-37-C. Alarm LEDs Local port Remote port Server antenna port UL and DL output monitoring port AC in and Switch Donor antenna port Ground contact DC Outlet for external device System Manual RSN-CDMA-37-C Proprietary & Confidential Page 5 Issue: 1.0 Operational parameters, such as gain, power levels, alarm condition, Automatic Gain Control condition, etc. are set using a desktop or notebook and the remote access is capable of control the RSN-CDMA-37-C.
