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.
