Multi-channel multiplexing method of super-high-speed wireless personal area network

Abstract

The invention discloses a multi-channel multiplexing method of a super-high-speed wireless personal area network, and belongs to the technical field of wireless communication. According to the invention, under a precondition that the time period occupied by a beacon period is not changed, an original time slot allocation time period without competitive access is modified as a channel switching period and a monitoring period; a second channel, except a main channel, is recorded as a secondary channel, a beacon period of the secondary channel is synchronous with that of the main channel; after a control node of the wireless personal area network detects that the secondary channel is idle, source equipment and destination equipment are switched to the secondary channel for communication; and when the secondary channel arrives at a channel switching start moment, if the information, which is sent to the control node of the personal area network by the source equipment and the destination equipment, shows that the source equipment and the destination equipment are not suitable to communicate in the secondary channel, the source equipment and the destination equipment are switched back to the main channel for communication. According to the method, an idle channel is utilized fully, and a gain of system throughput in a multi-frequency band multiplexing system is acquired.

Description

technical field [0001] The invention relates to an ultra-high-speed wireless personal area network multi-channel multiplexing method, which belongs to the technical field of wireless communication. Background technique [0002] Wireless Personal Area Network (WPAN) is a short-range (less than 10 meters) communication wireless network that connects devices such as personal computers, printers, storage devices, digital cameras, and high-definition digital televisions (HDTVs). Since the transmission of uncompressed high-definition video and large-capacity data files (such as high-definition pictures and lossless music, etc.) requires a transmission speed of gigabits per second (Gbps), it is necessary to increase the data transmission rate of short-distance wireless links. Current wireless technologies (such as UWB, Bluetooth, IEEE802.11n, etc.) support rates lower than 1Gbps, so they are not suitable for application in these scenarios. Therefore, many countries and regions hav...

Problems solved by technology

[0003] 60GHz millimeter wave technology can be applied to WPAN with a rate of Gbps level mainly for the following reasons: ① There is a wide continuous unlicensed frequency band in the 57-66GHz frequency band, which can enable high-speed transmission within the available bandwidth; ② 60GHz signal Due to the high path attenuation characteristics of indoor millimeter wave signals, the effective range of indoor millimeter wave signals is generally limited to within a few meters. If there are many obstacles in the room, the range may be smaller

When other channels are not occupied, that is, when the channel is idle, the channel cannot be used by the current personal area network, making the channel utilization rate of the entire system low
