Introduction 

 

In-building repeaters provide enhanced coverage of cellular 

telephone signals for areas that are confined or enclosed such as 

tunnels, underground parking garages, and within buildings.  Many 

buildings are constructed of materials like metal, brick and concrete 

that attenuate cellular telephone signals.  Symptoms such as 

dropped calls, broken audio and static indicate the need for an in-

building repeater.

 CR300 Small Office Home Office (SOHO) 

Cellular Repeater extends cellular services into buildings, parking 

garages, tunnels and other poor coverage areas.  The CR300 is 

designed for use with iDEN cellular handsets and offers a cost-

effective solution for small business and residential applications. 

 

The SignalReach

TM

 CR300 is a stationary device that automatically 

reradiates signals from cellular base stations without channel 

translation, for the purpose of improving coverage of existing 

service by increasing the signal strength in dead spots.  The 

repeater is a network-compatible device that amplifies cellular 

signals in both the uplink and downlink directions.  The repeater is 

simple to install, and contains circuitry to ensure proper operating 

power levels, and as well, includes an automatic feedback and 

detection circuitry that detects poor isolation between the subscriber 

and donor antennas.  In this condition the repeater will adjust its 

gain to compensate for the abnormality, and warn the user through 

a visual indicator LED.  The CR300 will enhance the cellular 

telephone user’s experience while complying with cellular network 

specifications.  Linear operation is guaranteed under all conditions. 

 

The CR300 allows up to two indoor antennas to be used without the 

need of external components.  Its auxiliary indoor antenna port 

allows a second indoor zone to be easily covered.  

 

This product is designed for installations where cellular coverage is 

available outside the building, and indoor coverage is inadequate.
