OFDMA based air interface eliminates the intra-cell interference
− Orthogonal transmission is ensured
Multiple Input Multiple Output (MIMO) configuration, up to 4x4 MIMO:
− Provides higher spectral efficiency
− Higher peak data rate
− Higher data throughput rates
Spatial Diversity Multiple Access (SDMA)
− Reduced interference
− Better cell coverage
Combining MIMO with SDMA optimizes network performance
Beamforming
− Reduced interference
− Improve capacity

Customer Environment UMB
Mobile Broadband is more and more important, Wireline will withdraw behind wireless access, ubiquity of wireless and bandwidth of wireline will together improve user experience.
New ISP such as Google� Ebay etc, and Intelligent terminals lead to the independence of service from network. Operators will lost the control of terminals and applications.
