Wireless receiving and dispatching system

Abstract

A wireless receiving and sending system is used to compensate the loss of transmission, it includes antenna, transceiver, tower top amplifier and transmission loss detector. The transceiver is used to send power and the first signal. The tower top amplifier is connected with the cable to receive the second signal from the transceiver, and zoom the second signal; the second signal is the first signal which passes the attenuation of cable. The transmission loss detector is connected between the tower top amplifier and the transceiver to detect that whether the transceiver remit signal, calculating the loss between the transceiver and the tower top amplifier. The tower top amplifier is used to remit signal to antenna or receive signal from antenna based on the detect result of the transmission loss detector, and compensates said transmission loss. Said wireless receiving and sending system can compensate transmission loss between the transceiver and tower top amplifier precisely.

Description

【Technical field】 [0001] The invention relates to a communication system, in particular to a wireless transceiver system. 【Background technique】 [0002] Referring to FIG. 1 , it is a schematic diagram of a traditional wireless transceiver system. A traditional wireless transceiver system includes a transceiver 10 , a Tower Mounted Amplifier (Tower Mounted Amplifier, TMA) 20 and an antenna 30 . The antenna 30 and the tower mounted amplifier 20 are located outdoors, and the tower mounted amplifier 20 is connected to the antenna 30, and the transceiver 10 is located indoors. The indoor transceiver 10 is connected to the outdoor tower mount amplifier 20 through a cable. Therefore, there is a transmission loss between the transceiver 10 and the tower mount amplifier 20 , which includes cable loss (Cable Loss) and connection loss (Connector Loss). [0003] Since the transmission loss between the transceiver 10 and the tower mounted amplifier 20 cannot be accurately measured be...

Problems solved by technology

Therefore, there is a transmission loss between the transceiver 10 and the tower mount amplifier 20, which includes cable loss (Cable Loss) and connection loss (Connector Loss)

[0003] Since the transmission loss between the transceiver 10 and the tower mounted amplifier 20 cannot be accurately measured before the installation of the wireless transceiver system is completed, the tower mounted amplifier 20 cannot accurately compensate for the transmission loss, which may cause the output power of the tower mounted amplifier 20 to exceed the legal power, It may also cause the tower mount amplifier 20 to be unable to work in the linear region, thereby reducing the performance of the wireless transceiver system
