In fact,Intelligent Automobile development is too fast Articles Lightsquared indeed field interference problems, but also threatened the United States military. In May 2011, the national space-based national executive committee and the Federal Aviation Administration and aviation radio technical committee Lightsquared GPS interference testing, to come to interfere with a very significant conclusion. In some tests, the receiver of the United States Coast Guard, the United States Aeronautics and Space Administration for the scientific use of the GPS system to be severely affected, similar to the U.S. Federal Aviation Administration (FAA) test results.

Lightsquared LTE network, compared with the GPS system, qualification is too "soft". The GPS system was jointly developed in the 1970s by the United States armed space satellite navigation and positioning system, now run by the Air Ministry and the Ministry of Commerce, used by millions of users around the world, the GPS system's primary goal is to provide the U.S. military, public safety and law enforcement agencies accurate location information, although the GPS is used for commercial, but is still essentially a military system. Lightsquared is only in recent years came out of the emerging LTE network operators want to contend with the qualifications seasoned GPS system, little chance of winning. Economic efficiency point of view, the application of GPS technology is growing year by year, the estimated annual revenue-generating $ 122.4 billion, and GPS downstream industries to create 5.8 million jobs. More than 3.3 million industrial and agricultural jobs in the United States, involving GPS technology, Lightsquared to deploy 40,000 ground satellite receiving stations, the program will have a GPS to generate destructive interference caused direct economic losses amounted to $ 96 billion to the U.S. GPS users and manufacturers. Therefore, the number of civilian, commercial enterprises and organizations, such as Trimble, FedEx, United Parcel Service, Jia Ming Co., Ltd. for GPS manufacturers, Delta Airlines, Southwest Airlines and agriculture equipment manufacturer Deere & Company formed to protect GPS alliance to boycott Lightsquared wantonly laying the plan of the LTE network in the United States.

In fact, several years ago, the interference problem already exists, can be prevented. FCC in 2010, a hearing will be shortened to 10 days to respond will be shortened to seven days, and interfere with the test before the vote to approve the Lightsquared of broadband systems, so let the Lightsquared immediately completed thousands of high-performance terrestrial signal transmission The device construction.Main product: dvd player for car   Why FCC Chairman Genachowski so hastily approved Lightsquared programs, and skip a key test of interference, for reasons unknown. Another point, the FCC is an independent U.S. government agency responsible for the authorization and management in addition to the use of the federal government outside the RF transmission devices and equipment, directly responsible to Congress. Fragmentation, lack of communication between the Government of the United States, has also led to the FCC approval Lightsquared initial commercial hurried response to FOR interference problems, the Department of Defense, Department of Transportation.
