A method for communication includes communicating between a first transceiver and a wireless communication terminal on a first channel, while identifying the first transceiver to the terminal with a transceiver identity. A roaming condition, which determines whether the terminal is to roam to a second transceiver operating on a second channel, is evaluated. Upon meeting the roaming condition, the terminal is instructed to switch to the second channel, and the terminal is subsequently communicated with using the second transceiver on the second channel while identifying the second transceiver to the terminal with the same transceiver identity as the first transceiver.
