Algorithms for detecting feeder line radio-frequency power and antenna standing-wave ratio in mobile communication system through RFID

Abstract

The invention relates to algorithms for detecting feeder line radio-frequency power and antenna standing-wave ratio in a mobile communication system through RFID. A feeder line radio-frequency power algorithm comprises that: for a certain radio-frequency power tag R, the response sensitivity is a constant Pref, and the output power of full power of a reader can be detected through the output power of the reader; and an antenna standing-wave ratio algorithm comprises that: for a certain standing-wave ratio tag V, when an antenna is normal, the reflected energy of the antenna is insufficient toexcite the tag, the tag V cannot be stored in a reader disc, and the reader sets a reasonable value for the standing-wave ratio of the tag V for representing a normal state of the standing-wave ratio. The calculation methods for the feeder line radio-frequency power and the antenna standing-wave ratio can effectively monitor the antenna and the feeder line in the mobile communication system so asnot to monitor the system through wired connection without additional cable. The engineering difficulty can be reduced, and the cost of network lines and twisted pairs in the mobile communication system is saved.

Description

technical field [0001] The invention relates to a detection method of a wireless communication device, in particular to a calculation method for detecting the radio frequency power of a mobile communication system feeder and the standing wave ratio of an antenna through RFID. Background technique [0002] With the rapid development of my country's mobile communication industry, especially the continuous expansion of 3G networks, wireless network optimization and network coverage are increasingly showing their importance. Commonly used coverage technologies include outdoor macro cells, indoor micro cells, distributed base stations, various repeaters (trunk amplifiers, tower top amplifiers, wireless co-frequency repeaters, optical fiber repeaters, frequency shift repeaters, carrier pools ) and other technical solutions, according to different communication standards, can be divided into equipment of different standards such as GSM, CDMA, WCDMA, TD-SCDMA, and CDMA2000. But no ...

Problems solved by technology

At present, such a monitoring system has the following problems: the master-slave (stationary) machine uses a network cable to realize 1-wire communication, and its internal power supply is not a complete passive system; when using ordinary network cables, the communication distance between the master and slave machines is relatively long Short, the use of high-grade cables can increase the communication distance, but it will increase the cost; the twisted pair connection between the slave machine and the feeder monitoring terminal also increases the cost; the structure of the whole system is complicated, which brings inconvenience to the installation and construction
