Description
The repeater works on the principle of receiving the handset signal
through a subscriber (indoor) antenna, amplifying or ‘boosting’ its
signal level, and then passing it on to the donor (outdoor) antenna
located outside the building. Signals from the cellular tower
(downlink) are also amplified and passed to the subscriber antenna.
The SignalReach
TM
CR300 in-building repeater is a Class B
Broadband device, and processes the iDEN/SMR 806-825/851-870
MHz band. Input and output duplexers and band pass filters in the
downlink and uplink path provide the repeater’s filtering and
isolation. The maximum gain in each of the downlink and uplink
path is 60dB. Both the downlink and uplink paths incorporate
automatic gain control, to ensure that downlink and uplink power
amplifiers operate free of distortion. The CR300 has primary and
secondary subscriber ports, allowing the repeater to expand the in-
building coverage area without degrading repeater performance.
