System Description RSN-4GIR-24S Proprietary & Confidential Page 4 Issue: 1.0 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.
