Abstract
A method of enabling a first wireless information device to access absolute location data in which the first wireless information device does not possess its own absolute location finding system but is instead able to receive, over a wireless network, absolute location data from a second wireless information device that does have its own absolute location finding system.The present invention hence enables wireless information devices to share absolute location data: for example, a mobile telephone with GPS capability can be used as a local ‘beacon’ to broadcast its absolute location to any nearby devices over a personal area wireless network (e.g. a Bluetooth network) so that those nearby devices can use that location data. Hence, a camera with no location finding system of its own could obtain location data from a nearby GPS equipped mobile telephone over a Bluetooth PAN and watermark its images with location data.
