Postal Letter

how does UPS or Fedex tracking status get updated ?

i have noticed that within minutes of the package getting delivered, the tracking website gets updated? do they have some sort of wi fi internet on their trucks? How does that information get transmitted?

1. They are linked, via satellite.
2. Yes. The drivers carry hand held devices.
3. the computer you sign on transmits something to the car and the car ttransmits something to the center and it updates the backages that are in the warehouse have labels on them and they have cameras that really sensitive and can read the lables n can update where the packages are and where they are going.
4. the use of radio frequency communications. This is one of the reason why the govt went to high-def was to free up low band freq
