Problems solved by technology

[0005] However, in terms of coverage control of wireless local area networks, there is no good solution in the prior art. The access point still sends management frames with full power and omnidirectional. This technology without any coverage control measures is not suitable for wireless enterprises such as Network and other occasions that need control signal coverage

[0050] As a first embodiment of the present invention, the measurement point may be a location where M sensors are deployed within the coverage area of ​​the access point of the wireless local area network, where M is an integer greater than 1. In the early stage of wireless local area network establishment, the number and location of the required access points are preliminarily estimated according to the size of the area to be covered, the environment, the coverage strength and the capacity requirements. Then, different areas are divided according to different signal coverage strength requirements. A typical division method is to divide the area into three areas: the inside, the edge and the outside of the wireless local area network. Deploy a certain number of sensors (for example, M) in different areas, select a representative position for the propagation environment in a certain area between the sensors, and the propagation environment correlation of different sensor positi...

Abstract

The invention provides a WLAN coverage control method and a sending parameter optimization method, device and system in order to lower the probability that terminals outside the coverage area of network information receive the network information and enhance network security. The method comprises the steps of obtaining optimal sending parameters, and using the optimal sending parameters or sending diameters obtained by calculating according to a multi-antenna scheduling algorithm sending a current frame to be sent according to the type of the current frame to be sent, wherein the type of the current frame to be sent comprises a management frame and a data frame. According to the WLAN coverage control method, the quality of receiving signals of terminals in the coverage area is guaranteed, the fact that the network key information carried by the management frame only can be received in a specific area is guaranteed, the safety of networks is enhanced, meanwhile, sending of the data frame and sending of the management frame is distinguished to be treated, the compromise between coverage control and multi-antenna processing gain is achieved to a certain degree, and therefore enough flexibility of multi-antenna scheduling is obtained.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a WLAN coverage control method, a transmission parameter optimization method, a device and a system. Background technique [0002] With the rapid development of broadband wireless access requirements, wireless local area network (Wireless Local Area Network, WLAN) technology and industry are increasingly mature and popular. Mainstream wireless local area networks can provide high-speed data transmission performance at relatively low cost. Considering factors such as compatibility, cost, and transmission bandwidth, WLANs usually use open frequency bands and simple wireless access mechanisms. When WLAN technology is used in a relatively closed network, the coverage of the signal has an important impact on the performance of the WLAN. When there are multiple adjacent WLANs, the coverage of the control signals can avoid mutual interference, because the technology used by most ...
