The Channel-Selective RF Repeater (RFR) is designed to provide a more cost-effective solution than adding a new Base Transceiver Station (BTS) to improve signal coverage and communication quality in wireless network. And its easy installation and maintenance can help carrier get fast return.

The channel-selective function can amplify only the signals transmitted by the customized 1 (2 or 4) channel.

Based on the working frequency, the Channel-Selective RFR can be subdivided into 2 categories:

• Single-Band Channel-Selective RFR: the channel-selective RF repeater that works on only one wireless system;
• Dual-Band Channel-Selective RFR: the channel-selective RF repeater that works on two wireless systems simultaneously.

In comparison with FSR (frequency shift repeater) and FOR (fiber optic repeater), the RFR (band-selective/channel-selective) has the following benefits and disadvantages:
