Radio vendors intro solutions at CES

Radio vendors intro solutions at CES

The International Consumer Electronics Show has started to serve as a launching pad for radio products for both the high-end consumer and commercial/government
  • Written by Urgent Communications Administrator
  • 1st February 2006

The International Consumer Electronics Show has started to serve as a launching pad for radio products for both the high-end consumer and commercial/government sectors. This year’s show highlighted a GPS-enabled scanner, an award-winning low-profile satellite antenna for vehicles with an integrated Wi-Fi hotspot in the supporting electronics, a hot-swappable hydrogen fuel cell, and a low-cost cellular phone signal extender for homes and small businesses.

Uniden’s BearCat BCT15 scanner uses GPS to provide automatic scanning selection based upon a user’s location. Users also can customize the scanner display to show location-based information. “Say I’m driving from Fort Worth to Dallas,” said Paul Optiz, Uniden’s product manager. “As I get closer to Dallas, it starts monitoring the frequencies associated with Dallas, and it drops monitoring frequencies around Fort Worth.”

The scanner is pre-programmed with state and local public-safety frequencies. It also can be programmed to deliver GPS-triggered alerts at areas of special interest, such as dangerous intersections and school zones.

Additional features include the BearTracker warning system, Uniden’s Close Call RF Capture Technology — which instantly tunes to signals from nearby transmitters — and dynamic memory management. In addition, the device has 2500 channels with a frequency range of 25 MHz to 1.3 GHz (excluding cellular and UHF TV frequencies). The BCT15 should hit retail shelves over the summer with a list price of about $380.

RaySat, a manufacturer of in-motion low-profile phased-array satellite antennas for vehicles, garnered substantial attention with its introduction of the StealthRay. The 5.7-inch high antenna is mounted securely on the vehicle’s roof and provides on-the-move, high-speed, two-way data connections for enterprise, government, military and public-safety users.

“The unique point for StealthRay is that it is the only system available for two-way connectivity. All other systems require you get to a remote location and then set up for data connectivity,” said Lynette Henley, RaySat’s director of marketing.

The system employs proprietary technology to receive a satellite signal using a unique set of phased-array panels that rotate and pivot inside a self-contained, weather-resistant housing. The panels automatically track a satellite to maintain a steady signal for clear data reception and transmission. Available now with price dependent upon service and configuration needs, StealthRay can operate with most of the Ku-band satellites worldwide and can be integrated with most VSAT terminal platforms in the market.

First responders also will want to take a look at Jadoo Power’s NABII fuel cell.

“There’s a clear need for mission-critical, off-grid reliable power,” said Jack Peterson, vice president of sales and marketing for Jadoo. “Over [a] year or two, without a trickle charge, a battery is dead. In the case of a fuel cell, you have the fuel and have 100 percent charge available.”

Initially marketed to the professional broadcast industry, the portable fuel cell power system is now being offered to first responders and other off-grid users to power laptops, radios and other portable devices. The NABII uses hydrogen gas in combination with air to generate power and has a virtually infinite shelf life when compared with batteries. It uses a hot-swap capability to avoid power interruptions and has a rapid refill/recharge time for fuel canisters. The fuel cell weighs a little less than 5 pounds and is able to generate 130 W/hr. of power at a 50 W load when combined with a 2-pound N-Store hydrogen fuel canister.
