Abstract

A system communicates with a mobile radio and includes a repeater that is operative for transmitting and receiving communications signals on respective first and second frequency hopping hopset. A mobile radio receives a communication signal from the repeater on the first frequency hopping hopset and transmits a communication signal to the repeater on the second frequency hopping hopset.

Claims

1. A system for communicating between “

N”

number of mobile radios comprising;

first and second repeaters that are operative for transmitting and receiving communications signals on different frequency hopping hopsets; and

“

N”

mobile radios that receive a communications signal from repeaters on a first frequency hopping hopset and transmit a communications signal to the respective repeater on a second frequency hopping hopset to reduce the number of radio paths participating in all-informed communications and enhance the probability that the “

N”

number of mobile stations may participate in a conversation with each other, wherein two mobile radios can be interlinked together using first and second repeaters and a dedicated single frequency hopping simplex communication.

2. A system according to claim 1, wherein said mobile radio comprises one of a handheld or manpack radio.

3. A system according to claim 1, wherein said mobile radio is operative as a combat net radio outstation within a combat net radio communications network.

4. A system according to claim 1, said mobile radio and repeater are operative for transmitting and receiving communications signals with one of Single-Channel Ground and Airborne System (SINCGARS) or Quicklook frequency hopping protocol.

5. A system according to claim 1, wherein said mobile radio is operative as a repeater.

6. A system according to claim 1, wherein said repeater comprises a mobile radio and includes a buffer for buffering communications signals.

7. A system according to claim 1, wherein said mobile radio is operative for transmitting communications signals having an identification for another mobile radio.

8. A system according to claim 1, wherein said communications signal comprises encrypted data.

9. A system for communicating between “

N”

number of mobile radios comprising;

a combat net radio communications network having “

N”

mobile radios and each operative for transmitting and receiving communications signals along different transmit and receive frequency hopping hopsets; and

first and second repeaters in communication with the “

N”

mobile radios contained within the combat net radio communications network and operative for communicating with the mobile radios on different frequency hoping hopsets such that mobile radios communicate to each other only through the repeater to reduce the number of radio paths participating in all-informed communications and enhance the probability that the “

N”

number of mobile stations may participate in a conversation with each other, wherein two mobile radios can be interlinked together using first and second repeaters and a dedicated single frequency hopping simplex communication.

10. A system according to claim 9, and further comprising another repeater and an interlink between repeaters and contained within said combat net radio communications network for enlarging the number of frequency hopping hopsets that can be used within the combat net radio communications network.

11. A system according to claim 9, wherein each mobile radio comprises one of a handheld or manpack radio.

12. A system according to claim 9, wherein each mobile radio and repeater are operative for transmitting and receiving communications signals with one of Single-Channel Ground and Airborne System (SINCGARS) or Quicklook frequency hopping protocol.

13. A system according to claim 9, wherein each mobile radio is operative as a repeater.

14. A system according to claim 9, wherein said repeater comprises a mobile radio and includes a buffer for buffering a communications signal.

15. A system according to claim 9, wherein each mobile radio is operative for transmitting communications signals having an identification for another mobile radio.

16. A system according to claim 9, wherein said communications signal comprises encrypted data.

17. A method of communicating between “

N”

number of mobile radios, which comprises;

receiving within “

N”

number of mobile radios a communications signal that had been transmitted from a repeater along a first frequency hopping hopset;

transmitting a communications signal from the “

N”

number of mobile radios to the repeater on a second frequency hopping hopset different from the first frequency hopping hopset to reduce the number of radio paths participating in all-informed communications and enhance the probability that the “

N”

number of mobile stations may participate in a conversation with each other; and

interlinking together two mobile radios using first and second repeaters and a dedicated single frequency hopping simplex communications.

18. A method according to claim 17, wherein the mobile radio comprises one of a handheld or manpack mobile radio.

19. A method according to claim 17, which further comprises transmitting the communications signals between mobile radios as combat net radio outstations in communication with the repeater within a combat net radio communications network.

20. A method according to claim 17, which further comprises transmitting and receiving communications signals on frequency hopping waveforms in accordance with one of Single-Channel Ground and Airborne System (SINCGARS) or Quicklook frequency hopping protocol.

21. A method according to claim 17, which further comprises transmitting and receiving communications signals to and from a repeater that is operative as a mobile radio.

22. A method according to claim 17, which further comprises communicating an identification within the communications signal identifying another mobile radio.

23. A method according to claim 17, which further comprises buffering the communications signal within a mobile radio operative as a repeater.

24. A method according to claim 17, which further comprises encrypting data within the communications signal.
