Problems solved by technology
When two AP devices working on working channel 1 and working channel 6 are installed relatively close together, the signal sent to working channel 1 may fall within the working frequency band of working channel 6, occupying the resources of working channel 6 and affecting the work. The normal operation of channel 6, and the signal sent to the working channel 6 may also fall in the working frequency band of the working channel 1, occupying the resources of the working channel 1, affecting the normal operation of the working channel 1, so that the two adjacent channels mutually serious interference

The present invention provides a WLAN device and a method for interference suppression by the WLAN device, and belongs to the communication technology field. The device comprises: an antenna, a band pass filtering unit, a transmitting-receiving switch and an integrated chip, wherein the operation bandwidth of the band pass filtering unit is a channel bandwidth of a preset operation channel. With the present invention, the operation bandwidth of the band pass filtering unit in the WLAN device is the channel bandwidth of the preset operation channel. The band pass filtering unit is used to filter wireless signals in the channel bandwidth of the preset operation channel so as to suppress interference signals outside the channel bandwidth of the preset operation channel, and the interference from other adjacent channels is suppressed, thus the mutual interference problem of two adjacent WLAN devices is solved.
Description
technical field [0001] The invention relates to the field of communication technology, in particular to a wireless local area network device and a method for suppressing interference of the wireless local area network device. Background technique [0002] Wireless Local Access Network (WLAN for short) refers to the application of wireless communication technology to interconnect computer equipment to form a network system that can communicate with each other and realize resource sharing. Wireless LAN no longer uses communication cables to connect computers to the network, but connects them wirelessly, which makes network construction and terminal movement more flexible. The WLAN includes a 2.4G frequency band and a 5G frequency band, wherein the 2.4G frequency band is specifically 2.4Ghz-2.4835Ghz, and the 5G frequency band is specifically 5.15Ghz-5.85Ghz. For example, the entire 2.4G frequency band can be divided into 13 sub-channels, each with a 5Mhz bandwidth. Usually W...
