Trapeze and DaVitas create seamless convergence for Wi-Fi and cellular handsets.

LAS VEGAS—Wireless mobility provider Trapeze Networks has teamed with DaVitas Networks, a new provider of mobility software and appliances, to deliver the ability for handset users to roam freely between Wi-Fi and cellular networks without interrupting a call. DaVitas will deliver handset software and an appliance for enterprise networks. Together with the Trapeze Mobility System Software and the companys new LAN Mobility Exchange switches, companies will be able to give users the ability to communicate using VOIP (voice over IP) over internal wireless data networks.
When the need arises to move outside of the enterprise coverage area, the Trapeze-DaVitas products will allow the user to roam between network types without interrupting a call.
"Were using WMM [wireless multimedia] with the 802.11e standard," said Trapeze CTO Dan Simone. According to Simone, this allows the Trapeze solution to be interoperable with offerings from other manufacturers because they can use compatible approaches to QoS (quality of service). "DaVitas brings the handoff capability for the handset," Simone said. He said that this code includes software that runs on the phone and on an appliance installed on the enterprise network. "Were carrier-agnostic," Simone said, adding that the convergence capability should work regardless of what type of cell phone a company decides to use.

While a number of companies have demonstrated handsets that can use either Wi-Fi or cellular technology, Trapeze said that this is the first that can move freely between these different systems. Simone said that the hardware for the convergence is already shipping, and that handsets with this capability should be available within a few weeks. "This is one of the first working fixed mobile convergence devices," said analyst Joel Conover, who is research director for Current Analysis. "Trapeze has reached out very early to partner with DaVitas," Conover said. He added that this will give them field experience that other companies dont have. Next Page: Making it work together.
