Network equipment providers and carriers are to boost interoperability between national wireless networks and enterprise wireless networks at the Cellular Telecommunications and Internet Association's CTIA Wireless 2003 show this week.

Nortel Networks and IBM, as well as carriers AT&T Wireless Services and Verizon Wireless, will lead the charge as the show kicks off in New Orleans.

Nortel will demonstrate technology that "incorporates data into existing networks", with a focus on bridging its public networks with corporate wireless Lans, according to Mark Morell, director of wireless strategic marketing at Nortel.

"We'll focus on demonstrating integration between WLans and public networks," Morell said. "We're helping carriers evolve their current networks to better integrate data along with voice."

Both Verizon and AT&T will focus on the enterprise customer and the extension of their collective networks to deliver more data services, officials said.

"We'll broaden our offerings to make them not as domestic-specific," said Ritch Blasi, a spokesman for AT&T Wireless.

"We're going to show GSM [Global System for Mobile Communications] and things that haven't been part of our business before. We're going to have new services and new devices."

Verizon will focus on the enterprise and detail capabilities within devices.

Wireless Lan interoperability is becoming increasingly important as companies try to achieve a seamless handoff between internal and public services, according to Keith Waryas, a wireless analyst at IDC. Wayras added that UMTS (Universal Mobile Telecommunications System) will be demonstrated in the United States for the first time.

UMTS is considered the next generation of networks for those operating on the older GSM, as do Cingular Wireless and AT&T.

Dejima, a maker of voice and text-driven controls for computers and gadgetswill announce its Direct Mobile Access, a carrier-grade product suite designed to enable single-step access to consumer information and services through text or speech.
