Abstract: A method for automatically retuning a specific broadcast program for a mobile or transportable device includes instructing the mobile or transportable device to stay on a specific broadcast program; monitoring a radio signal of the specific broadcast program broadcast from a first fixed location radio communication facility, when the radio signal is weaker than a threshold value, the mobile or transportable device searches a database thereof to find radio communication parameters of a second fixed location radio communication facility that broadcasts the same program as the specific broadcast program and locates most closely to the current location of the mobile or transportable device; and operably retuning the mobile or transportable device in the specific broadcast program broadcast from the first fixed location radio communication facility to the second fixed location radio communication facility according to the radio communication parameters of the second fixed location radio communication facility.

Abstract: A mobile or transportable device for radio communications include a mobile platform. The mobile platform has at least one antenna; a radio operating component coupled with the at least one antenna for receiving and/or transmitting radio signals; and a microcontroller coupled with the radio operating component, configured such that when a radio signal received by the radio operating component from one of fixed location radio communication facilities is weaker than a threshold value, the microcontroller searches radio communication parameters of a closest radio communication facility to a current location of the mobile or transportable device, and operably retunes the mobile or transportable device according to the radio communication parameters of the closest radio communication facility. According to the invention, certain functions of the mobile or transportable device may be performed remotely away from the mobile platform.
