According to Motorola, its new Melody platform lets push-to-talk and telephone interconnect users roam and communicate with other iDEN subscribers in four NII Holdings markets, Argentina, Brazil, Mexico and Peru, as well as with iDEN subscribers in the US. The Melody switching core platform has the ability to scale up in capacity over time to serve several million dispatch and interconnect subscribers and to expand to more than 1,000 cell sites.

Fred Wright, senior vice president for cellular and iDEN infrastructure business at Motorola, said: The iDEN Melody core architecture is a state-of-the-art design. It is a major mid-life network architecture upgrade program that will provide low-cost, scalable capacity to ensure long-term economic growth capability for iDEN network operators worldwide.
