Motorola demonstrated its vision for seamless mobility at its Moto4U event in Abu Dhabi on April 13. The activity was part of a four day programme of technical briefings to United Arab Emirates (UAE) service provider Etisalat. Motorola has carried out six seamless mobility technology trials with operators in the EMEA region. The physical demo centred on using a radio frequency identification (RFID) tag to identify when the user was moving from mocked up home, car and office environments and allow multimedia content to seamlessly follow the user. In this way, the user could be watching a music DVD at home and when he moves to the car, it switches to a CD of the same music without the user needing to button press the equipment. The IP-based technology that Motorola has developed behind the scenes is vital to the success of seamless mobility, says the vendor. “Without an IP-based network you couldn’t make the vision a reality. IP underpins everything from the wireless world to the mobile world,” says Margaret Rice-Jones, corporate vice president, Motorola Networks EMEA. “Problems such as being able to restart content where you left it off, say when moving from the home to the car, are solved by IP technology. This is because it is very much designed around enabling content and being able to start and stop sessions. All of these concepts have been built in to IP and the designers envisaged these kind of uses when they originally designed the protocol,” she adds. Motorola uses the IP multimedia subsystem (IMS) core architecture as its ‘glueware’ layer. This allows an operator with many different applications, and with servers from a variety of manufacturers, to use a common architecture to connect elements of the network. It also links to billing and provides an application layer that allows developers to take specific applications and link in to the network. Motorola is seeing operators upgrading their networks to IP-based technology, to take advantage of this new generation of functionality, although they can overlay IP technology into various pieces of the infrastructure without undergoing a complete upgrade.
