A communications network comprising a wireless local area network includes a plurality of access points connected to a host computer and each other, and a plurality of mobile units with each mobile unit being arranged for association with at least one access point. The mobile units are arranged to periodically scan for and identify the most eligible access point for association at the highest data rate on the basis of a performance criteria at the current data rate.

Data rate algorithms for use in wireless local area networks

A communications network comprising a cellular local area wireless network includes a plurality of access points connected to a housed computer and each other, and a plurality of mobile units 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 are situated adjacent exit points to detect when mobile units are in a vicinity. Each mobile unit may include paging facilities, including the capability of transmitting information in a coded form known both to the unit and to a host, and power-saving facilities.
