Problems solved by technology

[0007] (1) Each communication must be forwarded by the access point AP, which increases the transmission delay;
[0008] (2) Two competition channels are required, which increases the competition delay;
[0009] (3) There can only be at most one link communicating at each moment, and the network capacity is small;
The above-mentioned shortcomings of the prior art make it impossible to meet this requirement

Embodiment Construction

[0045] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0046] In order to describe the present invention conveniently, make following simplification:

[0047] The access point is: AP;

[0048] The first station is: STA1;

[0049] The second station is STA2:;

[0050] The direct communication request frame is: eRTS;

[0051] The direct communication permission frame is: eCTS;

[0052] The request to send frame is: RTS;

[0053] The permission to send frame is: CTS;

[0054] The confirmation frame is: ACK;

[0055] Such as figure 1 Described, the concrete steps of the present invention are as follows:

[0056] Step 1, the station STA1 sends a frame eRTS to the access point AP;

[0057] Among them, STA1 respectively writes the address of AP, the address of STA1 and the address of STA2 into the receiving address, sending address and destination address of the frame eRTS in order; and then sends the eRTS to t...

Abstract

The invention discloses a low-frequency band and low-power consumption wireless local area network station to station (STS) communication method. The method comprises steps of transmitting a data or communication request through one access point of two communication stations; (2) after the access point receives the data or a communication request, judging whether the two stations satisfy STS communication conditions, and if the STS communication conditions are satisfied, transmitting requests for building STS communication to the two stations; and (3) after the two stations received the requests, completing an STS communication mode. According to the method, a plurality of STS communication pairs are allowed to be existed in a network, so that the network capacity is effectively improved, and the transmission delay is reduced.

Description

technical field [0001] The invention belongs to the technical field of network communication, and particularly relates to a site-to-site direct transmission communication method in a low-frequency low-power wireless local area network, which is mainly used to improve network capacity and throughput, reduce site energy consumption, and reduce transmission delay. Background technique [0002] The wireless local area network based on the IEEE802.11 standard allows wireless connection in the local area network environment using the 2.4 or 5.8GHz radio frequency band in the industrial technology medical ISM frequency band that does not require authorization. There are mainly two networking architectures, one with fixed infrastructure and the other with no fixed infrastructure. Wireless LANs with fixed infrastructure are used in a wide range of applications, from homes to businesses to Internet access hotspots. [0003] In a wireless local area network with fixed infrastructure, ...
