NetMotion to update Mobility with VPN, routing support

NetMotion Wireless Inc. is set to release an update to its Mobility wireless connectivity and security software in early June that will add the ability to automatically switch users to the most reliable wireless network available to them, boost the encryption used in the software and add support for Nortel Networks Corp.'s Contivity VPN devices.

The new version of Mobility, 3.51, will be released on June 10, according to Shelly Julien, vice president of marketing at NetMotion, located in Seattle. Mobility is a client-server product designed for Windows PCs and Pocket PC handhelds that allows users to maintain connections to their applications while roaming across networks and subnets, as well as ensuring continuity of their wireless service across a broad range of IP (Internet Protocol) networks, she said.

In order to bolster connectivity, Mobility 3.51 adds "best bandwidth routing," which allows the Mobility server to automatically switch a device into the most stable and high-performance wireless service available to it, Julien said.

To do so, the server samples the various wireless services to determine their quality and then switches the device, she said. For instance, if a laptop were equipped with both an 802.11b card and a GPRS (General Packet Radio Service) card, the server would check both services and give the laptop most reliable service. If the laptop were moved out of range of the service being used, it would be switched onto the service still in range, she said.

Best bandwidth routing supports most IP-based protocols, including 802.11a and b, GPRS, GSM (Global System for Mobile Communications) and Bluetooth, she said.

Mobility 3.51 adds new, faster encryption algorithms to the product, support for Nortel's Contivity VPN (virtual private network) line, which a number of NetMotion customers use, and the ability for users to sign on to networks and applications from a single log-in thanks to support for Cisco Systems Inc.'s LEAP (Lightweight Extensible Authentication Protocol), she said.

NetMotion Mobility server runs on Windows NT and 2000 and the client runs on all Windows versions, including CE, Pocket PC and Pocket PC 2002, Julien said. The software will cost US$6,000 for 10 users.
