4G: The What, Why and When
There are many complex and interdependent moving parts that must work together before a standard definition of 4G is solidified. The benefits to service providers and end users drive the adoption of 3G services that, in turn, lead to the demand for even more advanced services. The realization of 4G tears down the wall between wireless and wireline services, a challenging endeavor. Realistically, wide-scale availability of 4G is several years away-somewhere in the middle of the next decade.
The purpose of this paper is to: Clarify the definition of 4G from a technology perspective; present business benefits of 4G-enabled services and propose a realistic timeline for the adoption of a 4G standard.
