One of the greatest brakes on progress of cellular services was always the slow and painful path to inter-operator roaming. The complex issues surrounding billing, customer ownership and cross-payments continue to plague the roll-out of every new service, including most recently, MMS messaging. If WiMAX is to achieve broad uptake on an international scale, it needs to address roaming at an early stage, and a first step has been taken with the formation of the WiMAX Global Roaming Alliance (WGRA). Such a system, according to its founder, will enable 802.16-based services to stop “striving to make WiMAX appear complementary to 3G†and set themselves up as a direct price/performance challenge.
