Communication module passes through the UART interface with microprocessor and links to each other, and shielding module passes through the SPI interface with microprocessor and links to each other, and communication module passes through the SPI interface and links to each other with shielding module, reaches and only disturbs basic station transmitting signal.
The communication module is connected with the microprocessor through a UART interface and used for information transmission between the microprocessor and the communication module, the AT command is used for controlling the communication module to carry out the task execution of frequency sweeping and monitoring, and meanwhile, the execution result of the communication module is transmitted and reported. The control shielding module is connected with the microprocessor through an SPI interface, and the microprocessor sends data to the shielding module through the SPI and controls the shielding device to transmit power commands. And the GPIO of the communication module is connected with the shielding module duplexer to realize time interval emission of TDD.

When a mobile phone accesses a cell, the base station sends a signaling to the mobile phone on a random access channel, so that the mobile phone is accessed to the base station, and functions of mobile phone conversation or internet access and the like are realized. And the microprocessor receives the frequency sweeping result of the communication module, issues an AT command to the communication module through the UART interface, and commands the communication module to enter a monitoring mode.
After receiving the command of the monitoring mode, the communication module detects the Received Signal Strength Indication (RSSI) of the cell, monitors the random access channel of the cell and analyzes the signaling.
