Description

A kind of data transmission method and equipment

Technical field

The present invention relates to communication technical field, particularly a kind of data transmission method and equipment.

Background technology

Wireless bridge can realize interconnection at the link layer of local area network (LAN) (Local Area Network, LAN) and can realize storage and the forwarding of message.Wireless bridge may be used for connecting the equipment being positioned at different separate network frequency ranges, has the advantages such as through-put power is large, long transmission distance, antijamming capability are strong.

At present, wireless bridge comprises following three kinds of bridge modes: 1) point-to-point bridge mode.Point-to-point type wireless bridge can be used to the network that connection two lays respectively at different location, is generally made up of a pair bridger and a pair antenna.This should be arranged to identical channel to bridger, and only need the channel of change one side bridger (being used frequency range), the opposing party's bridger just can change to corresponding channel automatically.2) point-to-multipoint bridge mode.The wireless bridge of point-to-multipoint can be connected multiple discrete long-range network, and structure is relative to more complicated point-to-point wireless bridge.Point-to-multipoint wireless bridge is some transmission wireless signal centered by a network usually, and other acceptance points carry out Signal reception.3) relaying bridge mode.Time not visible when needing to have barrier to block between two local area network (LAN)s connected, the method for wireless relay can being used to get around barrier, carried out the wireless bridging between 2.

Use Wireless Fidelity (Wireless Fidelity, WiFi) WLAN (wireless local area network) (Wireless Local AreaNetwork, WLAN) technology can pass through access point (Access Point, AP) and website (Station, STA) realizes wireless bridge function.AP with STA is connected with needing the equipment (as terminal, base station) communicated respectively, and by wireless transmission, those need the data between the equipment of communication, and the framework of system group network is shown in Figure 1, equipment B ₁, equipment B ₂need respectively to communicate with device A, equipment B ₁can by wire communication line and WiFi STA ₁connection, equipment B ₂can by wire communication line and WiFi STA ₂connect, WiFi STA ₁with WiFi STA ₂wireless communication line is connected with AP, and AP can be connected with device A by wire communication line, thus by wireless bridge transmission equipment B ₁with device A, equipment B ₂and the data between device A.

Current existing implementation is, AP comprises a radio-frequency module, uses identical frequency range to carry out transfer of data for realizing between each STA.Because WiFi is operated in unauthorized frequency range, the frequency range communicated may be subject to the interference that other are operated in similar frequency bands equipment, this radio-frequency module also needs periodically to scan the frequency range that AP supports,, because of disturbing change suitable frequency range for the radio-frequency module of AP and the radio-frequency module of each STA and proceed transfer of data during degradation with the transmission between AP and each STA.But, due in the process that AP changes in scanning and frequency range, cannot communicate between AP with each STA, thus the continuity of transfer of data cannot be ensured, and scan period transfer of data time delay greatly even packet loss, reduce Consumer's Experience.
