The Dual-Frequency Trunk Amplifieris traditional repeater, which can achieve the bidirectional simulated amplification of the base station uplink and downlink signal directly (without digital disposal). It is used to expand and extend the base station coverage, fill signal area where mobile signal is blind and weak.
Product Category:
The Wireless Repeater can be divided into Wireless Band Selective Repeater and Wireless Channel Selective Repeater.
Wireless Band Selective Repeater: amplify the signal of chose band. Bandwidth Fixed Single Wave Band Selective Repeater, Bandwidth Fixed Dual Wave Band Selective Repeater, Bandwidth Adjustable Single Wave Band Selective Repeater, Bandwidth Adjustable Dual Wave Band Selective Repeater.
Wireless Channel Selective Repeater: only amplifier the appointed signal in operating channel. The coverage products include Single Channelized, Dual Channelized, Four-channel Channelized, Six-channel Channelized, and Eight-channel Channelized Repeater.
According to the system composing the Wireless Repeater can be also divided into single system, dual system, and multi-system (above three).
