From: Howard Ward [mailto:hlward@terrasw.com] Sent: Friday, July 22, 2011 12:22 PM To: Julius Genachowski; Michael Copps; Robert McDowell; Mignon Clyburn Subject: Lightsquared filing Dear Mr. Genachowski, Please do not issue final permits to Lightsquared to operate a ground‐based broadband network in its authorized mobile satellite service spectrum. This technology has been determined (by Lightsquared’s own study) to interfere with high precision GPS. We need the efficiencies that come with these high precision devices to provide us with authoritative spatial data with higher accuracy at a lower cost. Until a solution can be found to block or filter the interference, you should not allow them to proceed. Sincerely, Howard Ward, President, GISP TerraSystems Southwest, Inc. 738 North 5th Avenue, Suite 203 Tucson, Arizona 85705 p: 520.322.0334; f: 866.568.4097 hlward@terrasw.com; www.terrasw.com
