There has been a tremendous growth in the field of wireless communications. The main factor behind this has been the wireless medium’s ability to satisfy substantially any two components of the three that comprise the ultimate goal of telecommunications: any information, any time, any place. Wireless communications systems provide anytime, anywhere communications. The future of wireless lies in faster more reliable methods of transferring data and to a lesser extent increased use of voice commands and audio improvements. The most notable factors that have contributed to this exponential growth are the Internet boom, the need for mobility in an ever-changing environment, low costs (flat rate), increased data rates, increased battery life, application friendliness and innovativeness.A wireless infrastructure has more ‘flexibility’ than a fixed infrastructure, in which at least the part of the access network closest to the user is dedicated to a specific locations and its profitability depends on the use made of this access by that household or business. Wireless networks do not suffer from this limitation; their use can be shared and reassigned much more easily, and they can become profitable more rapidly. Due to these advantages of wireless technologies there has been a tremendous growth in this field.
