LightSquared is attempting to construct a new nationwide wireless communications network across the U.S., according to the Agricultural Retailersr Association. It has been shown that the LightSquared network could have a negative effect on GPS signals. In order to build their network Lightsquared needed to acquire a waiver from the Federal Communications Commission (FCC).

In January 2011, LightSquared was able to attain that waiver, however, many associations and industries reliant on GPS, specifically precision agriculture, have pushed back against the LightSquared proposal. Senator Chuck Grassley (R-Iowa) has taken the lead in the Senate to demand that FCC withdraw their waiver until the appropriate tests are done to find the effect that LightSquared’s network would have on our nation’s GPS capabilities.
