Abstract
A system enables a device such as a mobile phone to operate as a transmitter and receiver over non-cellular radio frequencies such as very-high frequency (VHF) and ultra-high frequency (UHF) not natively compatible with the mobile phone. The system includes a radio appliance coupled to a radio that receives and transmits information over non-cellular radio frequencies. The radio appliance provides an interface between the radio and a web appliance accessible on a network such as the internet. The radio appliance receives information in broadcast from the radio and transmits the information to the web appliance over the network. The web appliance provides mobile devices access to the information received from the radio appliance, such as audio that was broadcast, over the network. Additionally, the web appliance may receive information from the mobile phone for transmission to the radio appliance and subsequent broadcast by the radio.
