摘要：

This paper first introduces the existing limitations of 3G network communication. It shows 4G is the inevitable trend of communication future development. 4G is a technology products which set 3G and WLAN in one, It has higher transmission speeds, greater capacity, better stability, may well make up for the deficiencies in 3G. The article discusses and analyzes key technologies of 4G such as OFDM, software radio, smart antennas, MIMO and so on. It points out the improvements of 4G in technology and analyzes changes in 4G network architecture. Final it concludes the improvements of 4G network compared with 3G. As the References of the new technology and the effectiveness improvement, this will bring 4G more broad application areas and market. © QingXia et al.; Licensee Bentham Open.
