xG Technology is conducting demonstrations for media and analysts showing how its xMax platform can be used to broadcast a data stream equal to full-motion MPEG-2 video with stereo sound at a distance of 18 miles using only 50 milliwatts of power.
Covering more than 1,018 square miles, the low-power digital broadcast was sent using the ISM 900 MHz unlicensed spectrum, the company says. The demonstration last week was conducted using an omni-directional antenna on a single tower in the Ft. Lauderdale-Miami area. Another demo was planned for this week in Fort Lauderdale.
The company says that by improving range, xMax reduces the amount of infrastructure required to provide coverage to a given area. Less power translates into improved battery life for mobile devices.
