merging technologies such as GPRS, EDGE and UMTS and protocols such as WAP will enable cellular providers, ISPs and ASPs to roll out new wireless services, including converged data and voice, m-commerce, mobile Internet and mobile videoconferencing. Preparing for the day when broadband cellular access becomes a reality, cellular operators are migrating their 2G circuit-based transmission networks from TDM, SDH or ISDN to packet-based ATM or IP backbones. This transition period is expected to continue for several years. Cellular operators will have to maintain and manage hybrid networks for some time, as legacy and 3G services co-exist side-by-side.

AD's flexible transport solutions offer a smooth migration path to evolving 3G networks while supporting current technologies and services. They provide the link to all types of equipment for both circuit-based and packet-based networks. The value proposition: Cellular operators can use the same infrastructure for all services and customers, for better utilization of resources and improved economies of scale.
