In live demonstrations at CTIA Wireless I.T. and Internet 2002, laptop data calls will be switched between the two network types with no interruption in service

Lucent Technologies today announced plans to demonstrate seamless handoffs of wireless data calls from a "WiFi" or wireless local area network (WLAN) to a third-generation (3G) CDMA2000 1xEV-DO network in its booth (#2400) at the Cellular Telecommunications and Internet Association (CTIA) Wireless I.T. and Internet show, taking place Oct. 16-18 at the Sands Expo and Convention Center in Las Vegas. The demonstrations will show laptop data calls being switched between these two types of wireless access networks with no interruption in service.

Lucent has developed this solution to help address the growing demand on the part of business users for uninterrupted high-speed data access by utilizing both 3G wide-area mobile networks, which offer ubiquitous geographic coverage, and WLANs, which offer high speeds but more limited coverage.

The demonstration will utilize Lucent's 3G CDMA2000 1xEV-DO network equipment, a laptop equipped with a Sierra Wireless AirCard(R) - a wide-area wireless PC Card, a Proxim ORINOCO(R) 802.11 WLAN card and ipUnplugged's Seamless Roaming Gateway solution. It also incorporates Mobile IP, a key standard established by the Internet Engineering Task Force (IETF), which enables seamless inter-technology handoffs between 802.11 and 3G technologies and is essential to maintaining "always-on" high-speed mobile Internet connections. This technique is made possible by a unique mobile network architecture developed by Bell Labs.

"We are excited to be able to demonstrate this capability, which has tremendous utility for mobile workers that need to access critical information while on the go using the fastest technology available," said John Marinho, vice president of offer management, Lucent's Mobility Solutions Group. "We are committed to helping mobile operators deliver secure 3G mobile data services such as this for the business marketplace."

There are also certain business segments that would find this capability useful. For instance, this technique would allow an IT field service engineer to begin downloading large files - such as technical schematics - from a wireless LAN at his dispatch center, and continue to receive this information while en-route to a service call, cutting response times substantially and making the travel time between locations more productive.

Lucent has also demonstrated seamless roaming capabilities between WiFi and 3G UMTS wireless networks.
