Preemptive Bewegung in einem zellularen drahtlosen lokalen Netz |
摘要 |
A communications network comprising a cellular local area wireless network includes a plurality of access points (5) connected to a house computer (4) and each other, and a plurality of mobile units (2) each mobile unit being arranged for association with an access point. The mobile units are arranged to periodically scan for and identify the most eligible access point for association on the basis of the criteria of best quality signal strength and loading factor. In order to identify when mobile units are being removed from a predetermined area, access points having directional antennae (22) are situated adjacent exit points (21) to detect when mobile units are in a vicinity. <IMAGE> |
