Abstract
In order to reduce power consumption of battery-powered devices to which location data is to be dissemination by short range communication, the devices are arranged to wake-up to listen for location data at known times as judged against a reference time standard. This time standard is also available to the transmitters of location data which accordingly transmit their location data at the known times.
