LTE MIMO indoor optical fiber distribution system wireless signal monitoring equipment and method

Abstract

The invention discloses wireless signal monitoring equipment and method of an LTE MIMO indoor optical fiber distribution system. The monitoring equipment comprises a slave monitoring part and a wireless signal RFID detection terminal, wherein a communication end of the slave monitoring part is connected with an integrated optical transceiver of a far-end slave and used for receiving a signal detection instruction sent by a near-end host computer and uploading monitoring result signals to the near-end host computer, a radio frequency output end and a radio frequency input end of the slave monitoring part are connected with a dual-polarized antenna of the LTE MIMO indoor optical fiber distribution system and used for outputting radio frequency test signals and inputting terminal feedback signals received by the dual-polarized antenna, and a control output end of the slave monitoring part is connected with an integrated power-amplifier low-noise-amplifier module of the far-end slave and used for outputting radio frequency output control signals to the far-end slave. The wireless signal RFID detection terminal communicates with the dual-polarized antenna and is used for receiving the radio frequency test signals and feeding the terminal feedback signals containing the identity information of a terminal to the dual-polarized antenna. The wireless signal monitoring equipment and method of the LTE MIMO indoor optical fiber distribution system can find network blind spots in time and optimize indoor LTE wireless network signals.
