摘要: A cellular communication system hand-off protocol which helps minimize down time associated with a mobile device roaming among different cells in employ channels (e.g., frequency hopping sequences). In preferred embodiment, each base station is configured to communicate its own particular sequence all other stations via the backbone. Each then provides devices are registered thereto information regarding sequences employed by servicing into may roam. Such includes together an indication of what location currently at any given time. addition, such include intervals transmit beacon packet (for passive scanning operation), or test pattern packets transmitted allow for signal quality evaluation.
