Overview

The holy grail of telecommunications services is a quadruple play where all services are offered on one access technology from one service provider. WiMAX has the potential to be that technology. In a fixed wireless configuration it can replace the telephone company's copper wire and cable TV's coaxial cable. In its mobile variant, WiMAX has the potential to replace cellular networks. In order for service providers to adopt WiMAX, platforms will have to demonstrate a strong quadruple play business case.

MIMO has the potential to transform WiMAX and other broadband wireless solutions to realize their true potential. Ultimately, emerging antenna technologies contribute to the erosion of incumbent landline market share and boost WiMAX and other broadband wireless access in the market place. This publication addresses the role and importance of antenna technology, including MIMO, to transform broadband wireless communications.
