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.

Claims

1. A system for enabling a mobile phone to transmit and receive on non-cellular radio frequency channels, the system comprising:

a radio appliance, the radio appliance comprising;

a first connection to a radio, the first connection configured to receive audio and channel information from the radio, the audio corresponding to a broadcast on the channel over a non-cellular radio frequency; and

a second connection to a server, the second connection configured to transmit the audio and channel information received from the radio to the server over a network; and

a server comprising one or more processors and a non-transitory computer-readable storage medium storing computer program code, the computer program code when executed by the one or more processors causing the server to;

receive the audio and channel information from the radio appliance over the second connection;

catalog the audio received from the radio appliance according to the channel over which the audio was broadcast on the non-cellular frequency;

receive a request from a mobile device to access the channel over the network;

transmit the audio to the mobile device over the networks;

queue information received from the mobile device for broadcast on the channel over the non-cellular radio frequency;

monitor the second connection to detect a silent line when the audio is not actively being received from the radio appliance; and

in response to detecting the silent line and responsive to a position of the information received from the mobile device in the queue, transmit the information received from the mobile device over the network to the radio appliance for broadcast on the non-cellular radio frequency.

2. The system of claim 1, wherein the second connection to the server is a Voice Over Internet Protocol (VoIP) connection.

3. The system of claim 1, wherein the server catalogs a network address of the radio appliance on the network.

4. The system of claim 3, wherein in response to receiving the information for broadcast from the mobile device, the server identifies the network address of the radio appliance based on its associated with the radio for broadcasting on the channel over the non-cellular radio frequency.

5. The system of claim 3, wherein the information includes a location of the mobile device, the computer program code when executed performing further operations to:

authorize transmission of the information over the network to the radio appliance in response to determining the location of the mobile device is within an authorized transmitting area.

6. The system of claim 3, wherein the second connection of the radio appliance to the server is further configured to receive the information from the server, the radio appliance further comprising:

a signal generator, the signal generator configured to generate a signal in response to receiving the information.

7. The system of claim 6, wherein the first connection to the radio is further configured to provide the signal and the second information to the radio for broadcast on the channel over the non-cellular radio frequency.

8. The system of claim 1, wherein the information includes audio and identifies the channel on the non-cellular radio frequency for broadcasting the audio.

9. A system for enabling a mobile phone to transmit and receive on non-cellular radio frequency channels, the system comprising:

a server comprising one or more processors and a non-transitory computer-readable storage medium storing computer program code, the computer program code when executed by the one or more processors causing the server to;

receive information for broadcast over a non-cellular radio frequency channel from a mobile device;

identify a radio appliance associated with a radio for broadcasting over the non-cellular radio frequency channel;

queue the information received from the mobile device for broadcast by the radio over the non-cellular frequency channel;

monitor a first connection to a radio appliance over a network to detect a silent line when audio is not actively being received from the radio appliance; and

in response to detecting the silent line and responsive to a position of the information received from the mobile device in the queue, transmit the information received from the mobile device over the network to the radio appliance for broadcast by the radio on the non-cellular radio frequency.

a radio appliance, the radio appliance configured to;

receive, over the network on the first connection, the information for broadcast over the non-cellular radio frequency channel;

generate a signal in response to receiving the information; and

provide the signal and the information to the radio over a second connection to broadcast, by the radio, the information received from the mobile device over the non-cellular radio frequency channel.

10. The system of claim 9, wherein the received information for broadcast includes audio.

11. The system of claim 9, wherein the first connection between the server and the radio appliance is a Voice Over Internet Protocol (VoIP) connection.

12. The system of claim 9, wherein the information received from the mobile device for broadcast includes location information, the received information indicating a radio function for broadcasting the location.

13. The system of claim 12, wherein the information received from the mobile device for broadcast is included in a message transmitted over a short message service by the mobile device.

14. The system of claim 9, wherein identifying the radio appliance comprises identifying a network address of the radio appliance associated with the radio for broadcasting over the non-cellular radio frequency channel.

15. The system of claim 9, wherein the information includes a location of the mobile device, the computer program code when executed performing further operations to:

authorize transmission of the information over the network to the radio appliance in response to determining the location of the mobile device is within an authorized transmitting area for the non-cellular radio frequency channel.

16. The system of claim 9, wherein the second connection of the radio appliance to the radio is configured to receive second information from the radio included in a broadcast over the non-cellular radio frequency channel, and the radio appliance is configured to transmit the second information received from the radio to the server on the first connection over the network.

17. The system of claim 16, wherein the server further comprises computer program code that when executed performs operations to:

receive the second information from the radio appliance over the second connection, the second information including audio and channel information;

catalog the audio received from the radio appliance according to the channel over which the audio was broadcast on the non-cellular frequency;

receive a request from a mobile device to access the channel over the network; and

transmit the audio received from the radio appliance to the mobile device over the network.

18. The system of claim 17, wherein the server catalogs a network address of the radio appliance on the network received in the second information.
