METHOD, DEVICE AND SYSTEM FOR ESTABLISHING CHANNEL FOR WIRELESS SIGNAL TRANSMISSION

摘要

A method, device and system for establishing a channel for wireless signal transmission are disclosed in the present invention, and said channel relates to a wired medium for connecting an access device with a distributed node. The method includes the following steps: the access device obtains communication performance parameters of the distributed node; the access device determines a frequency used for transmitting a wireless signal via the wired medium according to the communication performance parameters and the frequency spectrum range in which the access device can work; the access device adjusts its parameters based on said frequency, and transmits a message including said frequency to the distributed node, so that the distributed node can adjust its parameters according to said frequency, thus a channel for wireless signal transmission is established via the wired medium. The method, device and system provided in the present invention transmit wireless signals via the wired medium, and can configure parameters of modem automatically and establish a tunnel transmission channel automatically, thus improving the through-wall capability of wireless signals and also improving the coverage range of wireless signals.
