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

Embodiments of the present invention provide a WLAN coverage control method, a transmission parameter optimization method, device and system, so as to reduce the probability that network information is received by terminals outside the coverage area and enhance network security. The method includes: obtaining an optimal transmission parameter; according to the type of the current frame to be transmitted, using the optimal transmission parameter or the transmission parameter calculated according to the multi-antenna scheduling algorithm to transmit the current frame to be transmitted, the current frame to be transmitted Types of frames include management frames and data frames. The WLAN coverage control method provided by the embodiment of the present invention not only ensures the quality of signals received by terminals in the coverage area, but also ensures that the key network information carried in the management frame can only be received in a specific area, which enhances the security of the network, and At the same time, the transmission of data frames and management frames is treated differently, and a compromise between coverage control and multi-antenna processing gain is achieved to a certain extent, thereby obtaining sufficient multi-antenna scheduling flexibility.

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 ...
