There are all kinds of ways of transmitting GPS information. Garmin Rinos use FRS radio frequencies to transmit GPS information. The ability to pass GPS information is built into E911-compliant cellular telephone networks. Other techniques are also available but generally require a license from the FCC when used in the United States.
