Description:
The Frequency
Shifting Repeater (FSR)
consists of two parts: Donor Unit and Remote Unit. The Donor Unit
receives the downlink signal from base station and shifts it to
relevant channel, then transmits to the Remote Unit via relay
antenna. The Remote Unit reconverts the received signal to the
primary channel and covers the whole coverage areas. The Remote
Unit receives the mobile signal from coverage areas and also shifts
it to relevant channel, then transmits to the Donor Unit via relay
antenna. The Donor Unit will reconvert the signal to uplink signal
of the primary channel then send to the base station. Thereby
availably expand and fill signal area where mobile communication
coverage is blind, enhance communication quality. Applicable to
cover in the area where lack for fiber optic connection and uneasy
to lay cables or use to district network optimization, along with
occasion that installation is limited and the transceiver antenna
isolation is unsure. Such as: the telegraph pole nearby the road,
iron tower and the roof of the country etc.
Frequency Shifting Repeater Series:
According to relay frequency range the FSR can be sorted into In-band FSR and Out-of-Band FSR.
In-band FSR:the link frequency is within the working band of BTS;
Out-of-Band FSR:the link frequency is out of the working band of BTS.
As per the method of frequency shifting the FSR can be sorted into Band-selective FSR and channel selective FSR.
Band-selective FSR:shift and amplify the signal frequency in given band.
Channel selective FSR: shift and amplify the signal frequency in given channel (Single Channelized, Dual Channelized, Four-channel Channelized, Six-channel Channelized, and Eight-channel Channelized FSR).
As per the method of source picking up by the Donor Unit, the FSR can be sorted into Cable-Access FSR and Wireless-Access FSR.
Cable-Access FSR: receive base station signal via a coupler link to the base station;
Wireless-Access
FSR: pick
up base station signal in air via Donor Antenna (applicable when
the coverage areas under outspread are far away from base
station).
