Problems solved by technology

But all these methods do not guarantee the best sending rate
In the 802.11b and 802.11g standards, this shortcoming is not obvious, but under the higher rate 802.11n standard, the throughput can reach more than 150M, and one access point (AP) can access dozens of user stations (STA), at this time, because the influence of the number of subscriber stations in the same wireless channel on the transmission rate is not considered, the performance improvement of the wireless LAN using the above rate adjustment method is not significant

Embodiment Construction

[0018] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

[0019] figure 1 It is a flow chart showing a transmission rate adjustment method in a wireless local area network according to an embodiment of the present invention.

[0020] like figure 1 As shown, in step S110, the transmission rate adjustment factor of the wireless communication device is measured. Here, the transmission rate adjustment factor may be the packet loss rate / frame loss rate, detection packet success rate, continuous packet sending success rate, signal-to-noise ratio, and long-term smooth evaluation of the wireless communication device. However, these five factors are only exemplary adjustment factors that can be used by the present invention to determine whether to increase or decrease the transmission rate, and those skilled in the art can use any one of the transmission rate adjustment factors in the prior art or the prior art Any combina...

Abstract

The invention provides a transmitting speed adjusting method in a wireless local area network and a device using the same. According to the method, a conflict factor related to cochannel active equipment is introduced into a current rate adaption method, so that the influence of multiple pieces of wireless communication equipment in the same wireless channel can be considered, the performance of the wireless local area network when the wireless local area network has a plurality of users is improved, and better user experience is brought to the users.

Description

technical field [0001] The present application relates to wireless communication, and more particularly, to a transmission rate adjustment method in a wireless local area network (WLAN) and a device using the method. Background technique [0002] Wireless LAN technology is a technology that uses wireless electromagnetic waves to transmit signals. According to the propagation characteristics of wireless electromagnetic waves, the signal will be stronger near the wireless signal source, and the signal strength will gradually decrease as the signal propagates to a distant place. In order to make the signal cover a larger area, 802.11 technology adopts different modulation methods, high-order modulation is used in the near area, and the data transmission rate is high, and low-order modulation is used in the far distance, and the data transmission rate is low. The 802.11b standard supports four transmission rates: 1Mbps, 2Mbps, 5.5Mbps, and 11Mbps. The 802.11a standard supports...
