Microwave zooming wireless shrouding system and method

Abstract

The invention discloses a microwave remote wireless covering system and method. In which, the system comprises: a microwave accessing unit for receiving a radio-frequency signal from base station, converting into microwave signal, sending out through a microwave transmission unit, receiving the microwave signal from the microwave transmission unit, converting into radio-frequency signal and transmitting to the base station; a microwave transmission unit for performing microwave signal space transmission; and a microwave remote unit for receiving the microwave signal from microwave transmission unit, converting into radio-frequency signal, sending out to performing area covering, receiving radio-frequency signal from mobile station, converting into microwave signal and sending out through the microwave transmission unit; The microwave remote wireless covering system in the invention adopts microwave as transmission medium, can effectively reduce equipment cost, reduce engineering construction complexity, and greatly increase repeater networking flexibility and communication reliability; At the same time, the invention can effectively extend base station covering distance while guarantees that the normal work of the base station is not influenced.

Description

technical field [0001] The invention relates to a mobile communication network optimization system, in particular to a microwave remote wireless coverage system and method using microwave as a transmission medium. Background technique [0002] In the mobile communication system, the repeater is used as a relay device to amplify and forward the downlink signal of the base station or the uplink signal of the mobile terminal, and realize the extension of the function of the base station at a lower cost than the base station, so that the mobile communication signal The coverage is further improved. [0003] A repeater is generally composed of a base station (near-end) duplexer, a downlink amplifier module, an uplink amplifier module, and a mobile station (far-end) duplexer. The downlink is composed of a duplexer, and the uplink is composed of a remote duplexer, an uplink amplification module and a near-end duplexer. [0004] In order to extend the actual range of action of the...

Problems solved by technology

However, these types of repeaters limit the flexibility of repeater networking when faced with scarce wired transmission resources in some areas, and have disadvantages such as high equipment costs and complex engineering construction.

[0006] Moreover, since the physical cable is used as the transmission medium, the transmission link has a great influence on the reliability of the repeater. When the optical fiber, network cable or coaxial line fails, the entire repeater will be damaged. The failure of the machine affects the normal coverage of the communication system

Therefore, the traditional repeater using physical cables as the transmission medium is difficult to apply in applications such as difficult wiring, high communication reliability requirements, and fast coverage.
