The revolution of wireless communications has only just begun to transform the telecommunications industry worldwide. This book offers insight into the course ahead, the possible options for corporate stategists and government policy makers as they look to harness the expansion of wireless communications to meet the goals of sustainable telecommunications development. Using a multidisciplinary approach which combines policy research, legal analysis, business economics and models of sustainability from the environmental sciences, the book compares the development of wireless communications in four countries: the United States, the United Kingdom, Russia and Brazil. The comparative analysis points to common themes and opportunities, including: breaking down the barriers between wireless and wireline access by changing the regulatory design which constrains service providers; targeting the developmental potential of wireless access through the utilization of new technologies and service models; and using wireless access as the basis for full facilities-based competition in both developing and developed world markets.
