4G Revolution: WiMAX technology

Abstract

The 4G Revolution has begun with many of the advantages in wireless technology. The IEEE802.16 standard worldwide interoperability for microwave access is a technique which is used basically for the wireless and broadband for allowing high speed internet access for long distances. This new technique has made everything an mobile activity whether it is used as in business purpose or any other kind of task. The higher capacity and reliability of WiMAX make it useful in an efficient way. Security is the major challenge in wireless technology as because in wireless system it's very easy to tune with the radio signals. Security concerns in WiMAX with fixed and mobile stations. In fixed location WiMAX for internet access a fixed location radio technology is used rather than cable modem or DSL services. In mobile WiMAX a fixed location wireless access is provided to cable modem and DSL services. The comparative study between the fixed and mobile WiMAX in this research make some important issued to understand about this. The various generations of mobile technology are mentioned here to demonstrate the differences and the advantages of this new revolution. The very advance techniques of LTE and WiMAX are differentiated on various characteristics. And the security issues are there to resolve many of the problems that can harm to the wireless communication.
