The Road Ahead

The two IMT-Advanced technologies share many characteristics, as noted throughout this book. It has also been noted how little are the differences that exist between them. While much of the cellular market have chosen the 3GPP evolution track for future cellular networks, this does not mean the end of WiMAX as a technology. WiMAX applicability for fixed wireless broadband, in addition to its attractiveness to “Greenfield” wireless operators in various settings, indicates a sustainable existence for the IEEE technology. The general expectation, therefore, is that of co-existence, where each technology is appropriately deployed to achieve certain objectives – possibly non-overlapping.
