1.1 The challenge of dense and scalable wireless systems

For many decades wireless designers have focused on range and link performance. Communications systems were assessed in terms of their range and data-carrying capacity. Early cellular system designers and architects were concerned that the towers and base stations were assured to have sufficient range to provide complete coverage. However, the pervasiveness of wireless communications has almost reversed this consideration, and the emphasis in the development of wireless architectures must adapt itself to address fundamentally new technology objectives, since the success of future networks will be driven by network density and scalability.

While radio engineers once ...
