Current mobile communications architectures have increasing energy costs on both a unit, and often a per bit, basis. As requirements for bandwidth to mobile devices increases, it is important that the linear growth in energy consumption be avoided, or mobile communications will become an increasing source of energy consumption. This paper discusses the potential evolution of mobile architectures that can be both more responsive to usage growth and provide lower energy consumption through more localized access to mobile points of presence. This transition will dependent on a number of technology developments that can be foreseen in the reasonable future. These technologies include cognitive radio and networking, interference tolerance, and advanced wireless system architectures.
