To make way for the GPS LTE networks trap trapped Dead Before the Ship Even Sank Lightsquared, is a privately held company, is hedge funds

In November 2011,Interference problems dreams shattered  Articles 150 GPS engineers gathered at Stanford University, Stanford Linear Accelerator Center, to discuss the GPS market in the $ 110 billion in military and commercial aviation system. In the meantime, a major topic Lightsquared LTE (LongTermEvolution, and Long Term Evolution) network seriously interfere with GPS signals, pose a threat to the future of the GPS. The Lightsquared emerging LTE operators, due to its operational LTE networks interfere with GPS signals in the United States became the target of public criticism, has aroused the strong opposition of the U.S. GPS manufacturers, U.S. Army, Department of Defense, Department of Transportation, Department of Homeland Security, Agriculture the Department and the U.S. Congress have been involved in this signal interference war.

To make way for the GPS LTE networks trap trapped Dead Before the Ship Even Sank

Lightsquared, is a privately held company, hedge funds, Philip  The Faer Ken investment and management, was established in late 2010 has been committed to the development of LTE technology and satellite converged network, starting in 2010, Lightsquared attempt by satellite and ground-based mutual use of the deployment of an L-band coverage nationwide LTE network, and ambition to the 2012 commercial LTE network to cover 92% of U.S. users by 2015. Lightsquared network interfere with GPS signals  Lightsquared use satellite L-light wave band (1525Mhz-1559Mhz), and the spectrum of GPS and other satellite positioning systems (1559Mhz-1610Mhz) very close, so will greatly interfere with the GPS receiver . As a private enterprise, Lightsquared why dare with the GPS running in the same spectrum, with the support of the Obama administration are not unrelated. Early as February 2011, at Northern Michigan University speech, Obama proposed a plan of building a national wireless network (NationalWirelessInitiative), the program aims to build high-speed wireless network across the United States 98% of the population in the next five years, when the development rapid smart phones and tablet PCs can quickly access the Internet through high-speed network connecting every corner of the United States, so that the United States into the digital age. Therefore, Lightsquared Obama administration authorized the GPS running in the same spectrum. In addition, it won the support of the U.S. Federal Communications Commission (FCC). As early as January 2011, its commercial network has received preliminary approval of the FCC. If you do not interfere with GPS, then Lightsquared everything will be smooth sailing smoothly to the FCC's final commercial approval, with great fanfare in the United States to deploy LTE networks.

Interfere with GPS, however, broke the Lightsquared dream of, and therefore into a crusade against the dispute. For GPS camp censure, Lightsquared resist an application by the umbrella of the FCC, the FCC, that the interference problems mainly due to the GPS receiver has not been granted the right. GPS receiver will automatically track,Main products: car dvd player and car dvd , are with good quality. collect location data, in addition to the specified frequency bands are also scanned the adjacent frequency bands. The receiver will be adjacent Lightsquared network signal. In fact, this argument is a smoke bomb the Lightsquared consolidate its legal status, does not authorize the FCC is usually the case of GPS or other radio receivers, users do not need such as car, radio FCC license.
