System Description NOTCHCELL Repeater 1 Overview Å Installation of antenna Å Installation of Repeater DC Power Cable Feeder Line R-TRON NOTCHCELL repeaters are used to fill out uncovered areas in CDMA1900 mobile systems, such as base station fringe areas, road tunnels, business and industrial buildings, etc. A NOTCHCELL repeater 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. To be able to receive and transmit signals in both directions, the repeater is connected to a donor antenna directed towards the base station and to a service antenna directed towards the area to be covered. Control of the repeaters is performed using a desktop or notebook loaded with the R-TRON OMT, Operation and Maintenance Terminal, which can communicate with the repeaters either locally or remotely via wireless R-TRON Proprietary & Confidential Page 5
System Description NOTCHCELL Repeater data modem. Remote operation can be performed either via CDMA net. To be able to control many R-TRON NOTCHCELL repeaters in common, there is a Sprint EMS center. R-TRON NOTCHCELL Repeaters work as bi-directional amplifiers. A repeater receives, amplifies, and retransmits signals downlink and uplink simultaneously, i.e. from the base station via the repeater to the mobile stations and from the mobile stations via the repeater to the base station. The repeater can be connected to a donor antenna directed towards the base station, and to a distributor antenna directed towards the area to be covered. These antennas are connected to the repeater with type-N connectors. To prevent instability due to poor antenna isolation, R-TRON has developed NOTCHCELL Repeater. R-TRON NOTCHCELL Repeaters become clear of having superiority over the other RF repeaters in the world. The R-TRON NOTCHCELL Repeaters are controlled by powerful microprocessors. Alarm and operational status LEDs are visible on the bottom of the repeater. The repeater works with convection cooling without fan. Operational parameters, such as gain, power levels, alarm condition, Automatic Level Control condition, etc. are set using a desktop or notebook and R-TRON OMT, which communicate, locally via RS-232C cable, with the repeater. Remote operation is performed via CDMA net. R-TRON Proprietary & Confidential Page 6
