Motorola said it has completed the initial phase of its first 4.9 GHz broadband solutions in Tulsa, Okla.

Started in September, the trial included a network management terminal and two access points in suburban locations. Three vehicles equipped with Motorola's ML 900 laptop terminals tested applications such as Web browsing, instant messaging, e-mail and streaming video. During the trial, the system has been reliable and stable, according to the Motorola project team and Tulsa public-safety agencies participating in the trial.

Motorola also recently announced it has entered into an agreement with Nextel to implement Next Generation Dispatch (NGD), an IP-based P2T call-processing engine. Used with Motorola's iDEN technology, NGD is designed to replace the call processing system currently used in Nextel's nationwide network.

The NGD contract includes development of the IP based P2T server and an all-frame-relay backhaul solution from cell sites to the switching core, Motorola said.
