Embodiment

[0028] Such as figure 1 As shown, the wireless device signal transmission method provided by the present invention aims to achieve a balance between the three aspects of packet loss rate, bit error rate and bandwidth utilization rate. The specific steps are as follows:

[0029] First, the wireless access device and the wireless client implement 802.11 link negotiation through multiple antennas, establish a connection, and start data packet transmission. Assume that in a home environment, initialization is performed by the initialization module, so that seven wireless clients establish 802.11 link connections with the same wireless access device in turn to complete the preparation before the data message.

[0030] At this time, first check whether the number of connections of the wireless client to the wireless access device reaches the preset threshold, assuming that the preset threshold is 1, then check whether the number of connections on each wireless client reaches 1, if n...

Abstract

The invention discloses a wireless device signal transmission method which comprises the following steps(1) a wireless access device and wireless clients carrying out 802.11 link negotiation, establishing connection and beginning data message interaction; (2) checking whether the link number of the wireless clients on the wireless access device is smaller than a preset threshold, if the link number is smaller than the preset threshold, utilizing at least two antennas to send a beacon frame Beacon simultaneously and enlarging sending power, or otherwise, utilizing a single antenna to send a beacon frame Beacon according to a conventional power; (3) checking the transmission rate of data messages and adjusting a STBC function and RTS / CTS function according to the relationship of the transmission rate and the 802.11; and (4) transmitting the data message and finishing information interaction. The invention also provides a corresponding wireless device signal transmission device. With the combination of the transmission device and the transmission method, not only packet loss probability and error rate are reduced, but also the bandwidth utilization rate is ensured; and the wireless device signal transmission method and device have very high practical value and popularization value.

Description

technical field [0001] The present invention relates to a wireless device, in particular to a wireless device signal transmission method and device thereof which can improve transmission reliability. Background technique [0002] In recent years, with the continuous increase in the number of mobile users and the volume of real-time multimedia data traffic, users' demands on bandwidth, performance, and coverage of wireless local area networks (WLAN) are increasing. Currently, the representative standard of WLAN is 802.11. However, due to factors such as the effective signal coverage of wireless network equipment and available network bandwidth, no signal or unstable signal often occurs in practical applications; in addition, due to the unreliability of wireless network transmission channels, data transmission in WLAN There is a large packet loss rate or bit error rate. For this reason, some schemes to effectively improve system transmission performance have been proposed. F...
