Abstract: Mobile device access to a guest network is facilitated. A method comprises: detecting a home network having an associated access point based on the device being within a first defined proximity of the associated access point; and transmitting information indicative of a request to establish a guest network via the associated access point of the home network and providing authentication information for an entity associated with the device. The method also comprises establishing the guest network according to one or more assigned resources based on receipt of an acknowledgement message received from a cloud device, wherein receipt of the acknowledgment message from the cloud device is based on cloud device determination that the entity associated with the device is authenticated and based on receipt of an authorization by an entity associated with the home network.

Abstract: Over the air signaling of dynamic frequency selection operating parameters to client devices is disclosed. In an embodiment, a multi-channel master device determines a maximum range value of a radar detection umbrella associated with the multi-channel master device based on a first range representing a range at which the multi-channel master device detects a first radar transmission transmitted by a radar device at a defined transmission power; determines a compliance range value based on a second range representing a range at which the multi-channel master device detects a second radar transmission transmitted by the radar device at a dynamic frequency selection (DFS) compliance threshold transmission power; and determines a margin range value based on a third range representing a range at which the multi-channel master device detects a third radar transmission transmitted by the radar device at a transmission power that is lower than the dynamic frequency selection compliance threshold transmission power.
