3G MOBLE NETWORK

摘要

The provision of megabit/s data rates to thousands of radio and mobile terminals per square kilometer presents several challenges. Some key technologies permit the progressive introduction of such networks without jeopardizing existing investment. Disruptive technologies are needed to achieve high capacity at low cost, but it can still be done in a progressive manner. The key enablers are: • Sufficient spectrum, with associated sharing mechanisms. • Coverage with two technologies: parent (2G, 3G, WiMAX) for real-time delivery, and discontinuous Pico cell for high data rate delivery. • Caching technology in the network and terminals. • IP mobility. • Multi-technology distributed architecture.
