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.

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.
