Jammers put you in control of your new life

  Almost everyone uses GPS, including cell phones, car navigation devices, and nearly every conceivable commercial vehicle. Commercial aircraft use GPS to safely land the aircraft, especially in extremely low visibility.

Jammers put you in control of your new life

  Shipping lines use GPS to deliver products on time. Farmers use GPS to determine where to apply fertilizers and pesticides. This technology allows you to increase productivity and reduce waste. Troops use GPS coordinates to protect their troops and attack the correct targets.

  But you can turn passive into active with the help of jammers. You can turn off your device if you want others to know your location, but you don't want them to know you have GPS jammers turned on.

  Some hope to build a sprawling nationwide 4G cable network through satellite integration. Allowing them to use part of the frequency range (basically radio waves) for almost a decade, they say they want to use it now. Now they can start building, just need FCC approval.

  The problem is that this frequency range is adjacent to the range used for GPS signals. Opponents say the powerful network is swamping GPS transmissions, making it a disaster, economical and potentially life-threatening.

  Civil GPS systems use L1, L2, and L5 at frequencies of 1575.42 MHz, 1227.6 MHz, and 1176.45 MHz, respectively. The military uses the L3 band (1381.05 MHz) and the L4 band (1379.913 MHz).

  4G wireless networks use 1710-1755MHz and 2110-2155MHz for 3G frequencies, plus 2496-2690MHz for operation. LightSquared allocated spectrum from 1525 MHz to 1559 MHz.

  This is close to the GPS L1 band, and testing has shown that only 1% of the total frequency range used by GPS may be affected. If you want to protect your GPS from the new 4G network, you can use a jammer to block the new wireless network.
