Signal covering method for WLAN (Wireless Local Area Network) base station based on sector switch

Abstract

The invention provides a realization method for radio frequency of a WLAN (Wireless Local Area Network) base station based on multiple sectors. The WLAN base station adopts a multi-sector switch mechanism; each sector corresponds to one group of 3*3 MIMO (Multiple Input Multiple Output); sector network card chips are mainly used as receivers, correspond to all the sectors and are responsible for receiving corresponding sector data; a main network card is used as a transmitting chip for transmitting a management frame and a data frame to the sectors and also can be used for receiving any one link data; by multi-sector coverage, multi-channel transceiving and more sufficient time sharing multiplex, the number of concurrent users is greatly increased; the sector network cards are mainly usedas the receivers, and receiving of all the sectors is non-interfering, so that the antijamming capability of the base station is improved; when users in different sectors collide, one sector is only transmitted and further user collision of the base station is relieved; by adopting a multi-sector and multi-transceiving mechanism, an optimal path can be effectively selected, the signal processing capacity is improved and the covering range is widened.

Problems solved by technology

Because traditional APs generally use the 2.4G frequency band for coverage, the transceiver module used for coverage is generally composed of a single wireless communication module and a single radio frequency unit. When the AP is interfered by a certain direction, it may affect the performance of the entire device. , and the anti-interference ability is weak; due to the characteristics of the network card chip itself, the capacity of traditional APs is limited. For densely populated areas, in order to meet the coverage requirements, more devices are needed, which will lead to the deterioration of the networking environment and increase the difficulty of networking. ;Traditional AP improves the anti-interference ability by increasing the power of the device, which is difficult to achieve in actual networking. High power will lead to the deterioration of the entire networking environment. The power will cause the problem of unequal power between the transmitting link and the receiving link, which cannot effectively increase the coverage
