The invention discloses a channel distribution method and device, a data transmission method and access points. The defect that at present, the WiFi transmission speed is sharply reduced at an AP intensive distribution area is overcome. The channel distribution method includes the steps of receiving position information reported by the APs, computing to obtain the distances between the APs according to the position information of the APs, determining the adjacent AP, closest to the corresponding AP, of the corresponding AP according to the distances between the APs and the number of communication channels, and carrying out time division channel distribution on the APs to enable the APs and the adjacent APs of the APs to use the different communication channels at the same time slot to carry out data transmission. The embodiment of the channel distribution method and device, the data transmission method and the access points overcomes the defect that the WiFi transmission speed is sharply reduced at the AP intensive distribution area, and signal interference in the AP intensive distribution area is avoided.
Description
technical field [0001] The invention relates to communication technology, in particular to a channel allocation method and device, a data transmission method and an access point. Background technique [0002] The public WiFi provided by the operator uses the industrial, scientific and medical (Industrial Scientific Medical, ISM) working frequency band in the wireless local area network. In this frequency band, the frequency bands that do not interfere with each other and do not overlap each other are very limited. For a high-density wireless local area network (WLAN), when the same channel is crowded with different access points (APs), the transmission areas of these APs will be very large. Easy to overlap. As a result, AP signals back off each other, thereby degrading performance. Especially when there are multiple APs working simultaneously within 100 meters of a certain AP radiation, the influence of this mutual interference will be very obvious, which will lead to a sh...
