Public address system using wireless mobile communication devices

1. A mobile phone comprising:

a short range communication subsystem;

one or more communication subsystems; and,

a processor configured to:

send, using the one or more communication subsystems, a request, and responsively receive connection data for accessing a sound system using the short range communication subsystem, the connection data configured to trigger the processor to launch a wireless microphone application for using the short range communication subsystem to transmit wireless signals to the sound system; and,

in response to receipt of the connection data, launch the wireless microphone application.

2. The mobile phone of claim 1 , wherein the one or more communication subsystems comprise a long range communications subsystem, and sending the request occurs using the long range communication subsystem.

3. The mobile phone of claim 2 , wherein the long range communications subsystem comprises a cellular network communications subsystem.

4. The mobile phone of claim 1 , wherein the short range communication subsystem comprises at least one of a Bluetooth transmitter and a WiFi transmitter.

5. The mobile phone according to claim 1 , wherein the wireless microphone application enforces frequency damping to avoid feedback.

6. The mobile phone according to claim 1 , wherein the processor is further configured to provide a confirmation indicating that the request is pending.

7. The mobile phone according to claim 1 , wherein the wireless microphone application comprises one or more of: a pre-loaded application; a downloaded application from one or more of a wireless service provider and a web application provider; an automatically downloaded application that includes the connection data; and, an application downloaded from a radio frequency identification/near field communication tag.

8. A method comprising:

at a mobile phone comprising: a short range communication subsystem; one or more communication subsystems; and, a processor,

sending, using the one or more communication subsystems, a request and responsively receiving connection data for accessing a sound system using the short range communication subsystem, the connection data configured to trigger the processor to launch a wireless microphone application for using the short range communication subsystem to transmit wireless signals to the sound system; and,

in response to receiving the connection data, launching the wireless microphone application.

9. A mobile phone comprising:

a short range communication subsystem; one or more communication subsystems; and, a processor configured to:

receive, using the short range communication subsystem, connection data comprising password data for accessing a sound system;

in response to receipt of the connection data, send, using the one or more communication subsystems, a request and responsively receive a connection authorization message using the one or more wireless communication subsystems or the short range communication subsystem; and,

in response to receipt of the connection authorization message, launch a wireless microphone application for using the short range communication subsystem to transmit wireless signals to the sound system.

10. The mobile phone of claim 9 , wherein the one or more communication subsystems comprise a long range communications subsystem, and sending the request and receiving the connection authorization message occurs using the long range communications subsystem.

11. The mobile phone of claim 10 , wherein the long range communications subsystem comprises a cellular network communications subsystem.

12. The mobile phone of claim 9 , wherein the short range communication subsystem comprises at least one of a Bluetooth transmitter and a WiFi transmitter.

13. The mobile phone according to claim 9 , wherein the wireless microphone application enforces frequency damping to avoid feedback.

14. The mobile phone according to claim 9 , wherein the processor is further configured to provide a confirmation indicating that the request is pending.

15. The mobile phone according to claim 9 , wherein the wireless microphone application comprises one or more of: a pre-loaded application; a downloaded application from one or more of a wireless service provider and a web application provider; an automatically downloaded application that includes the connection data; and, an application downloaded from a radio frequency identification/near field communication tag.

16. A method comprising:

at mobile phone comprising: a short range communication subsystem; one or more communication subsystems; and, a processor,

receiving, using the short range communication subsystem, connection data comprising password data for accessing a sound system;

in response to receipt of the connection data, sending, using the one or more communication subsystems, a request and responsively receiving a connection authorization message using the one or more wireless communication subsystems or the short range communication system; and,

in response to receiving the connection authorization message, launching a wireless microphone application for using the short range communication subsystem to transmit wireless signals to the sound system.

17. A back-end system of a public address system, comprising:

an audio interface;

one or more antennas; and,

a computer configured to:

arbitrate between requests to access the public address system received from a plurality of mobile phones using the one or more antennas;

transmit, using the one or more antennas, connection data to a mobile phone of the plurality of mobile phones, the connection data configured to trigger the mobile phone to launch a wireless microphone application for using a short range communication subsystem to transmit wireless signals;

receive the wireless signals using the one or more antennas;

convert, using the audio interface, the wireless signal to audio signals; and,

transmit the audio signals to a sound system for amplification and broadcast over at least one speaker of the sound system.

18. The back-end system of claim 17 , wherein the connection data comprises a password for accessing the sound system.
