Abstract: Off channel scanning on workgroup bridge (WGB) devices for fast roaming may be provided. First, it may be determined, by a first WGB, that a second WGB is not off-channel. The second WGB may be peered with the first WGB. Next, the first WGB may perform channel scanning in response to determining that the second WGB is not off-channel. The first WGB may then prioritize a first WGB channel list based on results from the channel scanning performed by the first WGB. Next, the first WGB may roam while the second WGB in not off-channel, from a first access point to a second access point on a channel with the highest priority in the first WGB channel list.

Abstract: An apparatus includes a first wireless bridge device configured to transmit signals to and receive signals from wireless network access points located along a pathway, and a second wireless bridge device configured to transmit signals to and receive signals from the wireless network access points. The first wireless bridge device and the second wireless bridge device are coupled to and communicate with each other. When the first wireless bridge device is wirelessly connected to a first access point and about to initiate a roaming mode to attempt to wirelessly connect to a second access point, the first wireless bridge device notifies the second wireless bridge device of the initiating of the roaming mode and determines whether the second wireless bridge device is in the roaming mode while the apparatus is moving along the pathway.
