Towards the 4th Generation Mobile and Wireless IP Networks

摘要

This study introduces the background history of 1G to 4G, compares thedifferences between 3G and 4G and illustrates how 4G may work more powerfullyin future. The 4G has just been started. Besides, there are many technologies andstandards which are still in the developing process. However, a general idea can beenvisaged about 4G from academic research. The 4G evolution is based on 3G'slimitations and it will fulfill the idea of World Wide Wireless Web (WWWW)offering more services and smooth global roaming with inexpensive cost. Recently,wireless technology is getting popular and gaining importance in the network field.The main goal was to design a flexible, scalable, single wireless system that is morepractical, cost effective for mobiles and base-stations with characteristics requiredfor future business and service growth. This study made an effort to delve deepand wide into the exposition of the fourth generation (4G) wireless network system.
