Mobile multimedia considerations

The author considers how two approaches appear to meet the communication requirements of mobile multimedia applications.

The other approach is to build a wireless equivalent of the successful local area networks that carry the bulk of todayʹs multimedia traffic. We need new approaches that can create the technological breakthrough required for the next generation of mobile multimedia systems. The author discusses user interfaces, data compression and protocols
