A method, apparatus, and system for providing temporary access point (AP) functionality to an intermediary device to provide wireless network credentials to a wireless device (STA) to be connected to a wireless network including an AP is described. The intermediary device may mimic the AP to provide wireless network credentials to the wireless device and discontinue an onboarding session to allow the wireless device to access the AP directly.

Secured credential sharing over Wi-Fi protected setup

Methods for seamlessly onboarding commonly owned wireless local area network (WLAN) enabled devices to a wireless network are provided. Generally, the method includes exchanging an UID, encryption algorithm and key between the devices to form a common-onboarding-group (COG), manually provisioning credentials to onboard a first device of the COG, and automatically provisioning credentials to onboard a second device. In one embodiment, the first device registers with the network the UID and an encrypted-connection-profile encrypted using the algorithm, the network responds to a probe from the second device with the UID and encrypted-connection-profile, and the second device decrypts the encrypted-connection-profile using the secret key and joins the network. In another embodiment, the first device monitors the network and responds to a probe from the second device with the UID and encrypted-connection-profile. Alternatively, after onboarding the first device starts a private network and provisions the second device with the connection-profile.

System and method for efficient onboarding to a wireless network of a group of WLAN devices owned by a user

Disclosed are methods and systems for a WLAN device to select an operating dynamic frequency selection (DFS) channel that minimizes the probability of radar interference by using aiding information. The aiding information may be a crowd-sourced database of geo-tagged radar zones including one or more DFS channels used within the geo-tagged radar zones that are detected by a plurality of WLAN devices. The WLAN device may query the crowd-sourced database for a geo-tagged radar zone that is nearby to determine if a radar operates on an overlapping DFS channel so it may switch to a different channel. In one aspect, the aiding information may be periodic special action frames broadcast by a WLAN beaconing device over the operating channel of the WLAN device. The special action frames may carry information on one or more channels used by a near-by radar and recommended alternative channels to use by the WLAN device.

GPS-assisted collaborative and signaling-aided WLAN DFS operation

A system includes an apparatus and a station. The apparatus includes a first access point (AP) function configured to operate on a first channel of a first frequency band and a second AP function configured to operate on a second channel of a second frequency band. The apparatus also includes a processing device. In response to detecting that the second channel is unavailable for use by the second AP function, the processing device is configured to transition the second AP function to operate on a third channel of the first frequency band. The station can be used in an automotive application and is configured to communicate with the first AP function in the first frequency band, or communicate with the second AP function in the first frequency band or the second frequency band.
