Abstract: A wireless device, for operation within a wireless network, the wireless device comprising: a RF transmitter, a RF receiver, and processing circuitry, where the RF transmitter sends a radar-detected message or a channel-switch announcement message to other wireless devices in the wireless networks. The other wireless devices receive the radar-detected message and abandon radar-detected channels designated in the radar-detected message. The other wireless devices also receive the channel-switch announcement message and switch to radar-free channels designated in the channel-switching message.

Abstract: A method for use in a IEEE 802.11 device, comprising: wirelessly connecting, by the device, to a gateway that is part of a wireless local area network (WLAN), the gateway configured to operate as an access point (AP) for the WLAN and bridge the WLAN to the Internet; receiving, by the device from the gateway, an announcement message including a network identifier (NI) of a subnetwork of the WLAN, the subnetwork including the gateway and a first node that is also configured to operate as an AP for the WLAN; transmitting, by the device to the gateway, a request message to join the subnetwork; receiving, by the device from the gateway, a response message including a confidential credential for connecting to the subnetwork; establishing a first connection to the first node based on the confidential credential and the NI and beginning to operate as an AP for the WLAN.
