Embodiment Construction

[0040] In order to realize the purpose of the present invention, the present invention provides a multi-transceiver channel multiplexing method, at first the 8MHz frequency band of the Internet of Things is divided into smaller bandwidth sub-channels, and the access point with multiple transceivers makes each transceiver operate separately On different sub-channels, each transceiver manages multiple STAs and receives video surveillance data sent by multiple STAs, that is, STAs on different sub-channels run in parallel in frequency division multiplexing, splitting them into sub-channels is equivalent to increasing Independent channels realize parallel transmission, thereby increasing the channel access time; moreover, when the channel bandwidth is reduced and the transmission power remains unchanged, the STA can correspondingly increase the MCS (Modulation and Coding Scheme, modulation and coding strategy) level and data transmission rate , therefore, the multi-transceiver confi...

Abstract

A configuration method for multiple transceivers, a channel multiplexing method and device for multiple transceivers. The multi-transceiver configuration method includes the following steps: the access point obtains Ri(n) of the highest data transmission rate of N terminals STAi on each sub-channel n in the specified sub-channel combination, where 1≤i≤N, N is a positive integer greater than 1; calculate the channel access time Ti(n) required for STAi to transmit the average amount of data on sub-channel n, and when the specified sub-channel combination meets the allocation requirements of N STAi, access point to configure at least one transceiver for each subchannel n in the specified combination of subchannels. The invention realizes the parallel transmission of STAi by configuring multiple parallel transceivers on the access point side, increases the channel access time, reduces the channel bandwidth, improves the data transmission rate of the STA, and thus improves the network throughput.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a multi-transceiver configuration method, a multi-transceiver channel multiplexing method and a device. Background technique [0002] With the development of the Internet of Things, the wireless local area network oriented to the Internet of Things has a good development prospect. Among them, the wireless video surveillance network is a specific application scenario of the wireless local area network oriented to the Internet of Things. [0003] The wireless local area network standard IEEE 802.11ah for the Internet of Things divides China's 779-787MHz frequency band into eight 1MHz channels, four 2MHz channels, two 4MHz channels and one 8MHz channel. According to the channel division method of 802.11ah, the maximum channel bandwidth of the Internet of Things frequency band below 1 GHz used for various control or sensor devices in China is only 8 MHz (779-787 MHz frequency ...
