Local area network services delivery system

摘要

A system is described for delivering information services to the users of Local Area Networks (LANs), and more particularly of wireless LANs (W-LANs), which readily lend themselves to usage in large-scale installations and which support considerable user-mobility around the installation. In order to provide improved delivery to mobile users of location-specific information services, the system is provided with a plurality of wireless access points, distributed around the installation. The system can identify an access point receiving an information request from a mobile user, and can correlate the position of that access point with that of at least one other access point and/or with the position of at least one other feature of the site covered by the W-LAN installation, depending upon the nature of the request. The correlated positional information can be used to determine at least part of the information content supplied to the mobile user.
