MontaVista Linux at the Core of NexGen City’s VoIP, Push-to-Talk
Handheld Communicator For Public Safety Applications

Provides Fast Market Entry for New NexPaq Radio Handset for First Responders

SUNNYVALE, Calif., and RICHARDSON, Texas, July 19, 2004 — MontaVista Software Inc. today announced that NexGen City™, a manufacturer of mobile, high-speed wireless communications systems, has chosen MontaVista® Linux® Professional Edition as the operating system (OS) for its new NexPaq™ personal communicator for first responders. The NexPaq handheld communicator is an integral element of NexGen City's mesh-based NexLink™ wireless broadband mobile network, which combines data, VoIP (Voice over Internet Protocol) calls, and streaming video for police officers, firefighters, emergency medical teams, and municipal personnel.

“NexGen City chose MontaVista Linux with its large supporting software base to give us a fast entry into the market. We didn't want to have to reinvent the proverbial wheel. MontaVista Linux lets us do what we do best, develop advanced communications networks and applications for public safety,” said Kevin Farley, embedded software director, NexGen City. “We’ve used various RTOSes in the past and other embedded Linux products. We’re now planning to use MontaVista Linux on all devices throughout the NexLink network, and even in our Network Operations Center (NOC).”

The rugged, lightweight NexPaq unit is the industry’s first PTT/VoIP™ (Push-to-Talk/Voice Over Internet Protocol) radio handset. As part of its PTT functionality, the communicator has an emergency call button, a channel selection switch, and volume control. A command and control center can create virtual talk groups on the fly so that different first responder organizations arriving at the scene with NexPaq handhelds can communicate immediately on the same channel.

“The NexPaq communicator is an ingenious solution that will be extremely beneficial to local, state, and federal public safety officials and users,” said Mike Mathews, senior product marketing manager, MontaVista Software. “As wireless technologies rapidly evolve, the supporting software needs to be more robust to support their rich functionality and networking capabilities. MontaVista Linux provides a powerful systems software platform that can help quickly bring advanced devices such as the NexPaq communicator to market.”

Key Factors in the Selection of MontaVista Linux:
According to NexGen City, the following requirements led it to move to MontaVista Linux:

  • A commercial-grade software platform
  • A robust and versatile tools environment
  • Faster time-to-market for Nexgen City’s products.

Nexgen City says that the development effort was smooth and accomplished in a matter of months and, with the help of MontaVista Software, the project was carefully planned and executed.

The NexPaq Communicator
The rugged, lightweight NexPaq communicator runs embedded Linux on an Intel PXA255 microprocessor clocked at 400MHz. The first-generation device includes a backlit text display, keypad, cursor controls, and programmable multi-function keys in addition to its PTT functions.

NexGen City's NexLink Wireless Broadband Mobile Network
The NexLink network is a mesh-based communications system that can carry data, VoIP calls, and streaming video at broadband connection throughput rates of up to 1.5 Mbps (with bursts up to 6 Mbps), all while traveling at highway speeds in excess of 100 mph, according to NexGen City. Both mobile and fixed infrastructure devices are "network nodes" acting as repeaters and routers on the NexLink system. This creates a self-forming and self-healing network with ad hoc peer-to-peer networking capabilities. In the event of a major emergency that disables local fixed devices, first responders arriving on the scene can form a network automatically and seamlessly with their NexPaq communicators.

MontaVista Linux Professional Edition
MontaVista Linux Professional Edition (Pro) is the industry-leading comprehensive embedded operating system and cross development environment. It includes a modern OS featuring real-time functionality, multi-process capabilities and multi-threaded remote debugging, with extensive bundled software components including rich networking. Pro targets more than 25 processors from eight industry-leading architectures and supports more than 100 boards offering developers great freedom to choose the elements for their development environment, which, in effect, allows them to speed cutting-edge products to market faster and at a lower cost. Pro also incorporates MontaVista DevRocket™, a powerful integrated development environment that delivers state-of-the-art development tools.

The NexPaq intelligent communicator is currently undergoing extensive field-testing. The product is expected to be generally available in the fourth quarter of 2004.

MontaVista Linux product subscriptions provide developer teams with the MontaVista Linux kernel, deployment components, utilities, development tools, software updates, access to the MontaVista Zone (customer resource portal), comprehensive technical support and hands-on Linux training classes.
