Abstract
A data communications network including a number of stationary access points and a number of mobile units.
Each mobile unit is configured to scan for and select a most eligible access point for association therewith on the basis of received access point signal quality and loading factors at the access point. A physical area is defined within which all mobile units must be kept and access points are provided adjacent the exit point(s) from the physical area.
Each mobile unit is configured to scan for and select a most eligible access point for association therewith on the basis of received access point signal quality and loading factors at the access point. A physical area is defined within which all mobile units must be kept and access points are provided adjacent the exit point(s) from the physical area.
Claims (2)
1. A data communications network including a plurality of stationary access points and a plurality of mobile units wherein:
each mobile unit scans for and selects a most eligible access point for association therewith on the basis of received point for association therewith on the basis of received access point signal quality and loading factor at the access point and wherein:
a physical area is defined within which all mobile units must be kept and access points are provided adjacent the or each exit point from the physical area.
each mobile unit scans for and selects a most eligible access point for association therewith on the basis of received point for association therewith on the basis of received access point signal quality and loading factor at the access point and wherein:
a physical area is defined within which all mobile units must be kept and access points are provided adjacent the or each exit point from the physical area.
2. A network as claimed in claim 1 in which the or each access point at the respective exit point includes a directional (horn) antenna providing a strong signal in the vicinity of the exit point.
