The gsm rf repeater is designed to solve problems of weak mobile signal, which is much cheaper than adding a new base station (bs). Main operation of this repeater is to receive low-power signal from bs via radio frequency (rf) transmission and then transmit the amplified signal to the areas where network coverage is inadequate. And the mobile signal is also amplified and transmitted to the bs via the opposite direction.
According to your requirement for working frequency, you can choose either type of our gsm rf repeaters:
-ª Band selective rf repeater: to amplify all signals in the whole band (bandwidth is customized)
-ª Channel selective rf repeater: to amplify only the signals transmitted by the customized 1 (2 or 4) channel (a narrow band with customized central frequency)
The cdma rf repeater is designed to solve problems of weak mobile signal, which is much cheaper than adding a new bs (base station). Main operation of this repeater is to receive low-power signal from bs via rf (radio frequency) transmission and then transmit the amplified signal to the areas where network coverage is inadequate. And the mobile signal is also amplified and transmitted to the bs via the opposite direction.
According to your requirement for working frequency, you can choose either type of our cdma rf repeaters:
-ª Broadband rf repeater: to amplify all signals in the whole band (bandwidth is customized)
-ª Channel selective rf repeater: to amplify only the signals transmitted by the customized 1 (2 or 4) channel
The gsm frequency shift repeater is designed to solve problems of weak mobile signal, which can expand more coverage than rf repeater and reduce investment for the areas where fiber optic or dedicated cable is not allowed.
The system consists of two parts: donor unit and remote unit. The donor unit receives the bs signal via open air rf transmission or direct coupler closed to bs, then converts it from the working channel to transmission channel that is out of working frequency band, and transmits the amplified signal to the remote unit that will reconvert the signal to the working channel and provide signal to the areas where network coverage is inadequate.
