<p>A global access point information server 400 is suitable for use with a plurality of mobile devices 310, 320, 330 each of which contains at least a first and a second type of transceiver for communicating with base stations 110, 120, 130 via a first communication technology and with access points 210, 220, 230 via a second communication technology respectively. The global access point information server (400) stores access point information and other associated information related to a first region and includes a receiver for receiving sensed information from a mobile device, a processor for processing the received sensed information to identify a subset of the access point information data stored by the server which is pertinent to the mobile device and a transmitter for transmitting this information to the device.</p> |
