Abstract

The invention discloses an IEEE802.11AF (Institute of Electrical and Electronic Engineers 802.11AF) detection rate selection method. Three levels of rate table are used, wherein the matrix resource pool is formed by combining all physical rates specified by the IEEE 802.11 AF standard according to a certain mapping rule, and the matrix resource pool is a first-level rate table; a detection rate resource pool constructed by a dichotomy algorithm, a rate peripheral algorithm and a rate filtering mechanism is a second-stage rate table, and a rate resource pool to be detected selected from the second-stage rate table is a third-stage rate table finally used for detection; the method can avoid waste of channel bandwidthand performance fluctuation and reduction caused by improper detection rateselection, so as to shorten the period of dynamic rate selection, reduce the fluctuation of system throughput rate, and improve the data throughput of IEEE 802.11 AF wireless equipment in a wireless network environment.

Description

technical field [0001] The present invention relates to the wireless network transmission protocol of the IEEE 802.11AF standard, in particular to an IEEE802.11AF detection rate selection method applied to the dynamic rate selection part of the protocol, which can accurately locate the detection rate and shorten the selection period of the detection rate , to further improve the throughput and success rate of network data transmission. Background technique [0002] At present, with the rapid development of IEEE 802.11 wireless network technology, it has become a focus of attention and research due to its scalability, mobility and flexible network architecture. In the process of promoting the development of wireless network standards, the IEEE 802.11 working group successively formulated IEEE 802.11a, b, g, n, ac, ax and other standards. In recent years, on the basis of the original technology, the IEEE 802.11AF wireless network standard based on the blank frequency band not...
