Evolution of Personal Wireless Broadband Services from 3G to 4G

The chapter covers the basic conceptual model of the 4G system and the operations of its physical systems. It starts from the very basics of the wireless communication services, and then the author goes though the different standards of the systems which provide wireless broadband services, like the 3G, and other wireless broadband systems, like WiMAX etc. The author then looks through the 3GP project and its visions, then goes through the 3GPP2. The vision and the achievements of the 3GPP LTE are then discussed including the 4G and its successor systems. After that the authors turn towards the technical ideas behind the wireless broadband services like the 3G and 4G. 4G system architecture and its features are looked into, the differences between the 3G and 4G are discussed, and then the whole chapter is concluded with the impact of the 4G system on the present mobile communication scenario.
