Abstract

A first transmitting device is used to transmit a first signal on a first carrier frequency to a relay device. The relay device receives the signal by demodulating the first carrier frequency. Subsequently, the relay device retransmits the signal by modulating a second and/or a third carrier frequency. The signal is then recovered at one or more receiving devices by demodulating the second and/or third carrier frequencies. Further, a second transmitting device transmits a second signal on a fourth carrier frequency and the relay device retransmits the signal by modulating a fifth and/or a sixth carrier frequency. The signal is then recovered at one or more receiving devices by demodulating the fifth and/or sixth carrier frequencies. The transmitting and/or receiving devices are preferably voice terminals, such as a wireless telephones or data terminals, such as portable computers. The transmitting and/or receiving devices are optionally coupled to a communications network, such as a public switched telephone network or the Internet. The relay device is preferably a multiple beam satellite and/or a ground station covering several distinct geographical regions.

Claims

1-27. -27. (canceled)

28. A method of broadcasting a netted radio signal, comprising:

transmitting a message from a receiver, the message requesting participation in a distribution of the netted radio signal;

authenticating the receiver to participate in the distribution of the netted radio signal;

transmitting the netted radio signal to a plurality of recipients on an identified frequency using the distribution of the netted radio signal;

tuning a receiver to the identified frequency; and

receiving the netted radio signal on the identified frequency.

29. The method of claim 28, wherein the receiver is authenticated via a control channel.

30. The method of claim 29, wherein the control channel is separate from a channel used to transmit the netted radio signal.

31. The method of claim 28, wherein the netted radio signal is transmitted by a relay device.

32. The method of claim 28, wherein the relay device comprises a geosynchronous communications satellite.

33. The method of claim 28, wherein a plurality of netted radio signals are transmitted to a plurality of recipients.

34. The method of claim 33, wherein each netted radio signal in the plurality of netted radio signals is transmitted into a unique geographical area.

35. The method of claim 33, wherein each netted radio signal in the plurality of netted radio signals is transmitted into different geographical areas based on time.

36. The method of claim 28, wherein the netted radio signal is transmitted into a first geographical area at a first time and a second geographical area at a second time.

37. The method of claim 28, wherein the netted radio signal comprises a digital signal.

38. A method of broadcasting a radio signal, comprising:

receiving a message from a receiver requesting participation in a distribution of the radio signal, the radio signal being distributed to a plurality of recipients;

authenticating the receiver to participate in the distribution of the radio signal;

determining a frequency on which to transmit the radio signal; and

transmitting the radio signal on the determined frequency.

39. The method of claim 38, wherein the receiver is authenticated via a control channel.

40. The method of claim 39, wherein the control channel is separate from a channel used to transmit the netted radio signal.

41. The method of claim 38, wherein the radio signal is transmitted by a relay device.

42. The method of claim 38, wherein the relay device comprises a geosynchronous communications satellite.

43. The method of claim 38, wherein a plurality of radio signals are transmitted to a plurality of recipients.

44. The method of claim 43, wherein each radio signal in the plurality of radio signals is transmitted into a unique geographical area.

45. The method of claim 43, wherein each radio signal in the plurality of radio signals is transmitted into different geographical areas based on time.

46. The method of claim 38, wherein the radio signal is transmitted into a first geographical area at a first time and a second geographical area at a second time.

47. The method of claim 38, wherein the radio signal comprises a digital signal.
