In the last decade, developments in the telecommunications industry have changed our lives dramatically. Due to the high availability of broadband technologies, every piece of information we might ever need is within reach of our hands at work, at home, or wherever Internet access is provided. Cell phones enable us to stay ?on the phone? regardless of our location or the time of day. Now, the broadband Internet, which has previously only been provided via wireline technologies, is going wireless, providing more mobility and flexibility to users.
