An information service such as an airport information system relies on a network of Bluetooth(TM) transceivers to transfer information to a user's mobile phone, which is equipped with basic calendar functionality. The transceivers are connected to (an information server, which downloads the calendar from each of the devices and writes or updates the reminder in each device as appropriate. The mobile phone calendar therefore provides a backup in the event that the user moves outside of the network coverage, while the server carries out all of the necessary processing, so that the system does not rely on complex calendar software within the mobile devices.
