Data transmission method through one-way transparent relay access point

Abstract

The invention relates to a data transmission method through an one-way transparent relay access point and aims to solve the problems that according to an existing relay access point, users' throughput capacity is low, terminal throughput capacities are unbalanced and the relay access point is not compatible with existing management strategy of WLAN. The one-way transparent relay access point comprises a first wireless network card communicating with a wireless accessing point and a second wireless network card communicating with a secondary terminal. The method includes setting the first wireless network card as a mixed mode, and realizing the transparency of the wireless access point by a special address converting strategy. Since the first wireless network card and the second wireless network card are capable of operating in multiple non-overlapping communication channels simultaneously, the number of the terminals of each communication channel is decreased greatly, and the throughput capacity of each user is increased. Owing to the transparency of the one-way transparent relay access point corresponding to the wireless access point, the compatibility with the existing WLAN management strategy is guaranteed.

Description

technical field [0001] The invention belongs to the field of wireless local area networks, and in particular relates to a data transmission method using a one-way transparent relay access point. Background technique [0002] Although WLAN is widely used in various places and fields, the deployment of wireless access points (APs) is still relatively sparse in many large public places. Because most of the public wireless access points are uniformly deployed by a certain unit or organization, in order to cover the largest area at the lowest cost, the deployment density of wireless access points will be relatively low. When there are few users in a WLAN, the user throughput is acceptable. However, in real life, there will be a phenomenon that many users appear concentrated in a certain place. At this time, the WLAN will be overloaded, which seriously affects the throughput. Unfortunately, due to user mobility, when and where an overloaded WLAN occurs is difficult to determine. ...

Simple frame aggregation will lead to unfair upstream traffic between terminals

[0007] 2. For ordinary wireless access points, the relay wireless access point is only equivalent to an ordinary terminal, and the downlink bandwidth it can obtain is only equivalent to the downlink bandwidth obtained by an ordinary terminal, and the downlink bandwidth needs to be It is shared by the relay terminals belonging to the relay wireless access point, so the downlink throughput of any relay terminal is smaller than that of ordinary terminals, which leads to the unfair problem of downlink traffic between ordinary terminals and relay terminals

Because the existing relay wireless access point does not have the characteristics of transparent access, the access relationship between the relay terminal and the ordinary wireless access point is changed, so it will affect the existing WLAN management strategy
