Cell phones, televisions, and communication systems stop working the first day Malorie enters the home, but the car's GPS works days later. Cell phones have a range of up to 40 miles, and require towers. Televisions require either a physical cable or a local broadcast tower, either of which could lose power or be turned off. GPS uses satellites 12,000 miles above the earth, sending radio waves that cover the planet. Standalone GPS devices existed before the invention of smartphones. The satellites would need continuous control (currently from Schriever Air Force Base in Colorado, or Vandenberg Air Force Base in California) but it would likely be maintained as a priority by any working remnant of the US Air Force.
