1. Introduction

RSN-4GIR-30S repeater is used to fill out areas in Mobile WiMAX systems, such as base

station fringe areas, business and industrial buildings, etc.

RSN-4GIR-30S 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 yzuT[npyTZWzGRepeaters 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 yzuT[npyTZWzUG

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.
