Installation of Repeater

DC Power Cable

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 t o 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

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 c onnected to the repeater with type-N connectors.

To prevent instability due to poor antenna isolation, R-TR ON 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 communic ate, locally via RS-232C cable, with the repeater. Remote operation is performed via CDMA net.

The repeater is housed in a cast aluminum chassis that is waterproof, class NEMA 4x, for outdoor use. The chassis has a design suited for outdoor use as well as indoor use.

The chassis consists of a cabinet and a cover joined with hinges. The cabinet contains the repeater circuitry. Inside the repeater, a number of amplifier boards are individually shielded and located under a metal cover that can be folded out. These amplifier boards are different types depending on the supported system.

The followings are the Technical Specification of NOTCHCELL Repeater.

CAUTION: The antenna used for this transmitter must not exceed 20.15dBi and must be installed to provide a minimum separation distance of 3 meters from all persons.

3.3 Sub Unit Overview

Functionally, repeaters are built up with several sub units. The sub units of main repeater are as follows:

Band selective repeaters can handle multi-carriers over a wide band. The bandwidth is adjustable. A band selective repeater requires two UDC (with LNA) units and two PA units in the repeater. One pair of UDC (with LNA)/PA units is for uplink signaling and one pair is for downlink signaling.
