RSN-4GIR-24S
1. Introduction
RSN-4GIR-24S repeater is used to fill out areas in Mobile WiMAX systems, such as base
station fringe areas, business and industrial buildings, etc.
RSN-4GIR-24S 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:
„
188MHz bandwidth service
Band Selection (Continuous 30MHz) service
„
Roll Offs: 40 dBc at 1 MHz /80 dBc at 3.5 MHz outside pass-band
The RSN-4GIR-24S Repeaters are controlled by powerful microprocessors. Operational status
LEDs are visible on the front of the repeater.
The repeater works with convection cooling without fan because it has a radiator behind the
body of RSN-4GIR-24S.
Operational parameters, such as gain, power levels, alarm condition, Automatic Gain Control
condition, etc. are set using a desktop or notebook and the Local GUI or WEB GUI, which
communicate, either locally or remotely via the UTP(Unshielded Twisted Pair Wire) cable, with
the repeater.
