Description

technical field

[0001] The invention relates to data transmission protection technology, in particular to a data transmission protection method and device. Background technique

[0002] like figure 1 As shown, a basic service set (BSS, basic service set) of a wireless local area network (WLAN, Wireless Local Area Network) generally includes an access point (AP, Access Point) and multiple non-AP stations (non-AP stations). At present, the shared medium wireless network, especially WLAN, in order to share the transmission medium between multiple sites or multiple networks and avoid mutual interference, generally uses carrier detection technology to judge whether the channel is occupied. Carrier detection technology can be divided into two types, physical Carrier sense and virtual carrier sense. Physical carrier detection refers to monitoring the wireless channel to determine whether the received energy exceeds a certain threshold. If it exceeds the threshold, the channel is ...
