4G BROADBAND MAY JAM GPS The GPS industry is warning that a proposed broadband Internet network could effectively jam GPS signals. Further, it says it has data showing that any of the anticipated 40,000 (yes, four zeroes) transmitters can make a Garmin 430 go dark at a range of five miles. GPS World calls the proposal by LightSquared "disastrous" and warns of major problems for all kinds of GPS-reliant devices. The publication says a study (PDF) by GPS-industry stakeholders, including Garmin, determined the LightSquared network "will create a disastrous interference problem for GPS receiver operation to the point where GPS receivers will cease to operate (complete loss of fix) when in the vicinity of these transmitters." That, says the report, "will deny GPS service over vast areas of the United States." The industry told the Federal Communications Commission of the potential problem but the FCC approved the multibillion-dollar effort, which will carry 4G broadband throughout the country. In a podcast interview with AVweb, LightSquared spokesman Jeff Carlisle said the broadband system won't affect properly filtered GPS devices and his company is both mandated (by the FCC) and anxious to work with the GPS industry to identify devices that might be affected.
