xG peddling its xMax cognitive-radio system for public-safety use

Making a push to extend its all-IP cognitive radio network technology into the public-safety space, xG Technology said it will showcase its xMax private broadband wireless network solution during next month's APCO International Conference and Expo in New Orleans. The event should attract some 5,000 attendees and exhibitors and is the largest industry gathering of public-safety communications professionals.

The xMax is currently designed for the 902-928 MHz band.

The xMax system leverages software-defined radio (SDR) and cognitive radio access network technology to enable sharing of both licensed and unlicensed spectrum. The system's over-the-air waveform is designed for use in a fixed, low-latency cognitive radio network. The vendor contends its proprietary protocol "outperforms Wi-Fi, WiMAX and traditional cellular technologies like LTE in shared and interference prone radio bands."

Though xMax is technically frequency agnostic, it is currently designed to operate within the 902-928 MHz license-free band.

The xMax system includes access points, fixed and mobile personal Wi-Fi hotspots, mobile switching centers (MSCs) as well as network management and deployment tools. Once deployed, commercial devices with Wi-Fi connectivity, including smartphones, tablets and laptops, can be connected to an xMax System to enable voice, video, and data communications.

XG has been marketing xMax for use in numerous market segments, including incumbent wireless networks, rural telcos and wireless Internet service providers, defense, utilities and smart grid, mobile content providers and public safety. In public safety, the vendor is touting xMax as an answer to rapid-response emergency communications situations.

"Superstorm Sandy in 2012 knocked out 25 percent of the cellular towers in ten states, flooded dozens of communications centers, and wiped out power for weeks in some parts of the Northeast," noted Tim Moynihan, xG's vice president of sales. He said the xMax system is well suited to such situations because it is mobile and portable, self-contained and can be used to establish a private wireless network in about two hours.

Sarasota, Fla.-based xG claims 60 U.S. and more than 140 international patents and pending patent applications. The company has been pushing its technology since 2005 and completed an initial public offering of stock one year ago. For 2014's first quarter, xG's revenues were $250,000 compared to $0 revenue in the first quarter of 2013. Its quarterly net loss was $5.2 million, compared with a loss of $4.2 million during the first quarter of 2013.
