Methods and systems for determining local device proximity |
摘要 |
Methods and systems enable devices to discover each other when the devices are in a common location. Unique identifiers (UIDs) are associated with one or more location and each UID uniquely identifies a location. Devices that are located in a particular location that has a UID can register to create an association between the device and the UID. In turn, this creates an association between the device and a location. Subsequently, when another device (e.g. a laptop computer or PDA) enters the location, the device can discover the UID of the location and then ascertain which other devices are associated with that location.
