Data transmission method and relay device

Abstract

The invention relates to the technical field of wireless communication, and discloses a data transmission method and a relay device. The data transmission method comprises the steps that functional devices in the same space respectively establish first communication connection with a first relay device; the functional devices in the same space perform data transmission with the first relay devicethrough the first communication connection so as to realize data transmission among the functional devices in the same space; the first relay devices in different spaces respectively establish secondcommunication connection with a second relay device; and the first relay devices in the different spaces respectively perform data transmission with the second relay device through the second communication connection so as to realize data transmission among the first relay devices in the different spaces, so that data transmission among the functional devices in the different spaces is realized. The data transmission distance and the data transmission efficiency can be improved according to the method.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a data transmission method and a relay device. Background technique [0002] The inventors of the present invention found in the long-term research and invention process that the frequency bands where the communication protocols based on the existing repeater stations with long transmission distances generally have small bandwidths, and cannot realize fast transmission of a large amount of point-to-point data. For example, the communication protocols in this frequency band cannot Adapt to 4K ultra-clear video and VR technology, etc.; or the communication protocol based on the large bandwidth of the existing relay station, although it can meet the fast transmission of a large amount of point-to-point data, but its scalability is poor, the transmission distance is short, and it cannot be bypassed. With obstacles open, only line-of-sight communication can be a...

For example, the communication protocols in this frequency band cannot Adapt to 4K ultra-clear video and VR technology, etc.; or the communication protocol based on the large bandwidth of the existing relay station, although it can meet the fast transmission of a large amount of point-to-point data, but its scalability is poor, the transmission distance is short, and it cannot be bypassed. With obstacles open, only line-of-sight communication can be achieved, that is, face-to-face communication without obstacles
