Motorola intros mobile VPN

Motorola intros mobile VPN

Motorola introduced a Windows-based, mobile virtual private network solution developed specifically for public-safety and government users dubbed Multi-Net
  • Written by Urgent Communications Administrator
  • 1st April 2006

Motorola introduced a Windows-based, mobile virtual private network solution developed specifically for public-safety and government users — dubbed Multi-Net Mobility — that provides the triple play of intelligent routing, session persistence and secure connectivity as users roam between multiple wireless data networks, including Wi-Fi and mesh networks.

The key to the platform is its unique ability to provide all three attributes, said Mike Fabbri, director of Motorola Data Solutions Operation, who added that competing platforms at best offer two of the three.

“We have a whole wireless broadband business targeting government and municipalities, both public safety and government services,” Fabbri said. “And what our customers were saying is that the mobile routers out there today don’t provide all three of the key things that Multi-Net Mobility will provide.”

The introduction is a significant development because most VPNs aren’t built for mobility, according to Rob Whitely, analyst for Forrester Research. “There are three shades of VPNs — those that are ‘friendly’ toward mobile devices; those that offer one, maybe two, of the important distinctions; and a much smaller subcategory that offers all three,” Whitely said. “Mobile links are, by nature, low bandwidth, high latency and quirky. … You need all of those tricks to make the mobile VPN work.”

The system consists of a client application that resides in the customer’s ruggedized laptop and a server application that resides in the core network, Fabbri said. The client application constantly monitors the wireless applications available and facilitates intelligent routing as the user moves between networks. Meanwhile, the server application ensures the connection is secure.

Fabbri added that the Multi-Net Mobility platform’s authentication and encryption applications meet government standards for secure connectivity, while the session-persistence capability eliminates the need to restart applications when short-term lapses occur as users move between networks. Also, the intelligent routing capability lets users better manage applications across multiple networks.

“For example, you wouldn’t want to send a high-bandwidth requirement, such as streaming video, over a lower-bandwidth network,” he said. “Users can create profiles for the various networks based on speed or, potentially, cost.”

Not only does the client application select the proper network based on application, it also will make certain adjustments on the fly.

“Depending on the size of the pipe, the software might throttle back [on video] from good quality 15 frames per second to a more moderate three or four frames per second,” Fabbri said. “So the footage gets choppier, but at least there still is some level of video.”

Of the three primary capabilities, session persistence is most important to first responders, according to Steve Devine, patrol frequency coordinator for the Missouri State Highway Patrol.

“Session persistence has been kind of problematic … and I think Motorola’s goal is mobility that’s seamless to the end user,” Devine said. “It needs to be where [first responders] don’t have to do anything. … They have more important things to do.”

Although Fabbri said Motorola sees application for the Multi-Net Mobility platform in the enterprise sector in the future, Whitely said mobile VPNs chiefly are a public-safety and government play now.

“Most enterprises already have invested in a VPN infrastructure of some kind, and while they also have mobility plans, they don’t have their businesses absolutely dependent on mobility — it’s a productivity enhancer,” Whitely said.

Base station for broadband networks

Nokia’s Flexi base station is designed for broadband wireless networks operating in frequencies from 1700 MHz to 2100 MHz, including wireless-CDMA (W-CDMA), HSPA (high-speed packet access) and WiMAX. The device will be available for W-CDMA and HSPA (2100 MHz, 1700 MHz, 1800 MHz and 1700/2100 MHz) in the second half of 2006, with additional frequencies (including 850 MHz, 900 MHz and 1900 MHz) scheduled to be added in the first half of 2007. A 700 MHz version eventually will be added as well, the company said.

Intelligent battery backup

A battery backup module developed by ICT resides between the base station and the battery to provide uninterruptible power to 12 V devices. A microprocessor control prevents over-discharge of the battery by disconnecting the load should voltage fall below 10.5 V. In addition, the module ensures that the base station receives adequate power while the battery recharges after commercial power returns, the company said. It is available in both stackable and stand-alone designs.

Lightweight, hand-held base station analyzer

Anritsu introduced the MT8222A BTS Master, a hand-held base station analyzer that weighs just 8 lbs. It incorporates the company’s Site Master cable and antenna analysis technology to deliver “highly accurate” return loss/VSWR, cable loss and distance-to-fault (DTF) measurements, the company said. In addition, the device conducts two-port measurements — such as gain, isolation and insertion loss — to verify sector-to-antenna isolation. Such measurements are necessary because of the proliferation of diplexers, duplexers and tower-mounted amplifiers in many 3G base stations. An optional built-in bias tee eliminates the need for an external power supply.

Wireless system alerts crew of ‘man overboard’

Ember’s ZigBee networking technology is now featured in Raymarine’s LifeTag personal wireless “man overboard” system. The system protects boats with up to 16 crewmembers by wirelessly communicating each member’s status to a LifeTag base station. For example, when a person or animal has gone overboard, saltwater rapidly degrades the wireless signal on the LifeTag device and triggers an alarm to alert the crew. The LifeTag alarm also is activated when a member moves beyond 30 feet of the boat, as well as through manual activation by pressing and holding a red button for 3 seconds.

Each LifeTag system consists of a base station and two wearable LifeTags. The base station handles communication with each LifeTag and provides outputs for external alarm sirens and relay contacts.
