Current Technology Developments of WiMax Systems [PDF ebook] 

Support

Recent developments on wireless communication technology have resulted in tremendous innovations to make broadband wireless networks able to compete with 3G cellular network. IEEE 802.16X standards have not only specified Wi Max wireless access networks but also designed a framework of wireless metropolitan area networks with mobility functionality. It is obvious that with further development of various Wi Max technologies, wide range of high-quality, flexible wireless mobile applications and services could be provided, which will revolutionarily improve our modern life to achieve the goal of accessing the global information at any place and at any time by any mobile device in the future. Current Technology Developments of Wi Max Systems addresses the recent developments of Wi Max technologies for both academia and industry. It is expected to be a good reference for further research and development on Wi Max systems.
