Ericsson Review
Jambala Mobility Gateway—Convergence and inter-system roaming
Written by: André Bertrand
Download PDF file
As business becomes truly global and international, the need to communicate anytime, anywhere becomes more crucial. The demand for international roaming has grown spectacularly and is expected to continue growing into the new millennium. With the tremendous installed base of GSM and TDMA/AMPS wireless networks in the world, international roaming has evolved to require inter-system roaming capability; that is, roaming between GSM and TDMA/AMPS networks. In addition, operators seeking to enter established wireless markets are increasingly requiring the use of inter-system roaming to enable them to use the cellular coverage offered by partners in the same or neighboring areas. The author describes the Jambala Mobility Gateway, a new application from Ericsson that provides the level of convergence necessary to interface GSM and TDMA/AMPS networks.
