Abstract

The invention provides a device and a method for reading data in spectral analysis. In a system composed of network management equipment and AP (assembly program) equipment, the device is specifically a logical device formed by computer instructions of a CPU (central processing unit) performing memory of the network management equipment, and performs the following processes including that A, the network management equipment is used for reading frequency interference data acquired by the AP equipment from periodicity on an MIB (management information base) of the AP equipment, a reading period of the network management equipment is greater than that of the AP equipment acquiring the frequency interference data; and B, after reading is completed, multiple frequency interference data are judged whether to jump or not, if yes, all frequency interference data are abandoned, and the step A is returned to read the data once more. By the technical scheme of the device and the method for reading data in the spectral analysis, the problem of inaccurate interference signal graphs caused by reading distortion of the frequency interference data in the prior art is solved effectively.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a device and method for reading data during spectrum analysis of a wireless AP in a WLAN network. Background technique [0002] WLAN (Wireless Local Area Networks, wireless local area network) provides a wireless connection service of a local area network, which can provide high-speed wireless data access. Compared with the traditional wired access method, WLAN makes the use of the network more free, completely getting rid of the shackles of cables and port locations, and WLAN has the advantages of being portable and easy to move. [0003] The 2.4G and 5G frequency bands where WLAN works are open and free to use, and various radio frequency devices may cause interference to wireless signals. For example: Bluetooth devices, cordless phones, paging systems, and wireless cameras. The analysis of interfering signals in a wireless network is called spectral analysis. ...
