Embodiment Construction

[0039] Such as figure 1 As shown, the front of the repeater is provided with an external MIC jack, a liquid crystal display, a multi-function button, a power indicator, a transmitting indicator, a receiving indicator, a line input indicator, an alarm indicator, and an internal speaker from left to right. The back of the repeater (not shown) is provided with a reserved antenna interface, a Line line input and output interface, a grounding post, an AC power input interface, and an antenna interface in sequence from left to right. Through the existing advanced mobile terminal vehicle-mounted station, handset, etc., the transmitting module and the receiving module are composed, and then the purpose of signal forwarding is achieved through the setting of the control board, so as to realize wireless communication.

[0040] Such as figure 1 As shown, when the two repeaters Tx1 and Rx1 are working, they can automatically switch between A and B modes, which is equivalent to dual-machi...

Abstract

A wireless communication system for performing signal forwarding through a duplex-mode relay station is characterized by comprising two relay stations which can be automatically or manually switched in the backup working mode of an A machine and a B machine, wherein each relay station comprises a transmitting module and a receiving module which are independent, and each module has both the functions of receiving a radio frequency signal and transmitting the radio frequency signal; the transmitting module and the receiving module are communicated with a duplexer respectively; the duplexer is communicated with an antenna; the antenna is wirelessly communicated with a handset; and the wireless communication system has a conventional mode (namely, the transmitting module and the receiving module can work independently and back up each other) and a mutual control mode (namely, each module has both the functions of transmitting and receiving, and two channels backing up each other are formed on a relay station). The volume of the relay station is minimized, the signals at different frequency ranges can be received or transmitted, different base stations can be accessed, the functions of the A and B machines are fulfilled, receiving and the transmitting can be independent, and the 300-1000m remote mutual control can be realized.

Description

technical field [0001] The present invention relates to a repeater in duplex mode, and also relates to a wireless communication system for signal forwarding by the repeater in duplex mode, which has the functions of floating charge for AC and DC, automatic adjustment of transmission power, and upgrade of analog cluster. Background technique [0002] In the prior art, the analog repeater (or repeater) can perform signal forwarding in half-duplex mode, and the coverage of the repeater needs to be determined by the setting of the transmission power and the height of the antenna; a single product can only When performing inter-frequency transceiving repeater mode, the base station mode of co-frequency transceiving cannot be enabled. In the analog repeater station of the prior art, there is a lack of functions of AC and DC dual-purpose floating charging, automatic adjustment of transmission power, and upgrade of analog trunking. Contents of the invention [0003] The object of...
