Method for communication in coordinator-based wireless network, and method for communication between coordinator-based wireless networks connected with back bone network

A first adjuster connected to the underlying wireless network and the backbone network, the second coordinator-based wireless communication methods between the network data transmission containing information needed for the second coordinator-based wireless network and a remote channel time allocation from the access point for connecting the backbone network notification and receiving the frame step, the relay device is the first mediator by the said relay unit is provided in the channel time step, and assigned for transmitting a remote CTA frame to the request to the second coordinator a channel time allocation and a step of receiving a data frame from the wireless network based.
