Description

technical field [0001] The invention relates to the field of communication technology, in particular to an access point device of a wireless local area network and a signal processing method thereof. Background technique [0002] At present, the packet data processing module and radio frequency module of the access point (Access Point, AP) device of the wireless local area network (Wireless Local Area Networks, WLAN) are connected through the mini Peripheral Component Interconnect (mini Peripheral Component Interconnect, mini PCI ) interface or a miniature accelerated peripheral component interconnection standard (mini PCI-Express, mini PCI-E) interface for communication connection, among which, the number of pins of the mini PCI interface is up to 188, and the pins of mini PCI-E The number is also as high as 52, which limits that the packet data processing module and the radio frequency module of the access point device of the WLAN must be bundled together.

Problems solved by technology

[0004] First, the form of the equipment is not flexible. Once the equipment is deployed, if it needs to be changed (such as increasing capacity, changing frequency bands, etc.), new equipment must be re-deployed, which makes the workload larger and less flexible.

[0005] Second, the access point device can only achieve remote and indoor distribution through the splitter and combiner of the radio frequency signal, such as the attached figure 2 Shown is a schematic diagram of a traditional remote WLAN access point device and an indoor setup. The channels in each coverage area are the same. Although the coverage area is increased, the coverage capacity is not increased, so more users are brought by the increase of the coverage area. Will create greater conflicts, thereby degrading the user's network experience

In addition, the splitters and combiners will increase the radio frequency insertion loss, so that even if the transmission power of the device increases, it will decrease at the user side due to the attenuation of multiple splitters and combiners, and the power consumption requirements of devices that support high-power transmission will also decrease. larger

[0006] Third, if multiple radio frequency modules are required, it is necessary to set up mini PCI interfaces or mini PCI-E interfaces corresponding to the number of radio frequency modules, and the increase of interfaces will increase the complexity of the system and the complexity of the main processor

Moreover, when there are multiple radio frequency modules, due to the short distance between the interfaces connecting the radio frequency modules, the radio frequency modules are relatively close to each other, and the interference is relatively large.

[0007] To sum up, the existing access point equipment layout lacks flexibility, limited coverage capacity, and poor scalability
