WLAN base station radio frequency achieving method based on multiple sectors

Abstract

The invention provides a WLAN base station radio frequency achieving method based on multiple sectors. A multi-sector switching mechanism is adopted in a WLAN base station. Each sector corresponds to one set of 3*3 multi-input multi-output (MIMO), a sector network card chip is mainly used as a receiver, and each sector is responsible for receiving the data in the corresponding sector; a main network card is used as a transmitting chip, transmits management frames and data frames to the sectors, and meanwhile receives data in any link; multi-sector coverage is achieved, multi-channel transmitting and receiving are achieved, time-sharing multiplexing is more sufficient, and the number of concurrent users is greatly increased; due to the fact that the sector network card is mainly used as the receiver, all the sectors do not interfere with one another in receiving, and the interference resisting capability of the base station is improved; when a user collision occurs on different sectors, only one sector is sent, and the base station user collision is relieved; due to the multi-section multi-transmitting-receiving mechanism, the optimal path can be effectively selected, the signal processing capacity is improved, and the coverage range is enlarged.

Description

technical field [0001] The invention relates to the technical field of communication equipment, in particular to a multi-sector-based WLAN base station radio frequency implementation method. Background technique [0002] WLAN base stations use electromagnetic waves to send and receive data in the air, effectively solving the problem of network channel connectivity that is not easy to achieve by wired methods. Due to the advantages of high mobility, low price, easy expansion, and high transmission rate, WLAN technology has been widely used at present. It is widely used in the field of wireless extension.

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
