Abstract

A communication system includes a first communication module, and a second communication module. The first communication module may receive a first type of communication signal (e.g. a mobile telephone signal) and convert it into a second-type of communication signal (e.g., a millimeter wave radio signal). The first type of communication signal may be a mobile telephone signal from a first fire fighter'"'"'s mobile telephone who is located outside of the building. The first communication module may transmit the second-type of communication signal to the second communication module.

Claims

1. A communication system, comprising:

a first communication module adapted to;

receive a first type of communication signal, convert the first type of communication signal to a second type of communication signal and transmit the second type of communication signal to a second communication module;

the second communication module on a building and adapted to receive the second type of communication signal from the first communication module, and transmit the second type of communication signal inside the building to a third communication module at a power level based on a signal-to-interference level;

the third communication module located inside the building and adapted to receive the second type of communication signal, convert the second type of communication signal into the first type of communication signal, and transmit the first type of communication signal,

the third communication module is also configured to receive the first type of communication signal, convert the first type of communication signal into the second type of communication signal and transmit the second type of communication signal to the second communication module;

the second communication module is configured to receive the second type of communication signal from the third communication module and transmit the second type of communication signal to the first communication module; and

the first communication module is configured to receive the second type of communication signal, convert the second type of communication signal to the first type of communication signal and transmit the first type of communication signal.

2. The system of claim 1, wherein:

the third communication module comprises communication processing circuitry that is configured to validate the second type of communication signal; and

the third communication module only transmits the first type of communication signal if the second type of communication signal is validated by the communication processing circuitry.

3. The system of claim 1, wherein the first type of communication signal is a mobile communication signal.

4. The system of claim 1, wherein the first type of communication signal is carried over at least one of:

a 400 MHz frequency band;

an 800 MHz frequency band;

a 900 MHz band;

an 1800 MHz band; and

a 2 GHz frequency band.

5. The system of claim 1, wherein the second type of communication signal is a millimeter wave signal.

6. The system of claim 1, wherein the second communication module is mounted adjacent a window inside the building.

7. The system of claim 1, wherein the second communication module is mounted adjacent a window outside the building.

8. The system of claim 1, wherein:

the second communication module comprises at least one antenna that is a low to moderate gain array antenna.

9. The system of claim 8, wherein the low to moderate gain array antenna comprises interconnected beam-forming array patterns on both outward and inward facing sides, separated by an intervening ground plane.

10. The system of claim 1, wherein:

the first communication module comprises communication processing circuitry that is configured to validate the first type of communication signal; and

the first communication module only transmits the second type of communication signal if the first type of communication signal is validated by the communication processing circuitry.

11. The system of claim 10, wherein the communication processing circuitry validates the first type of communication signal if the first type of communication signal is an emergency telephone called, placed, or received by emergency personnel.

12. The system of claim 1, wherein the first communication module is mounted on top of a vehicle.

13. The system of claim 1, wherein the first communication module is mounted to a structure at ground level.

14. The system of claim 1, wherein the first communication module is mounted to an elevated structure.

15. The system of claim 1, wherein the first communication module comprises an antenna, wherein the antenna is a high gain fan beam antenna.

16. The system of claim 1, wherein the system is configured for floor-to-floor communication.

18. A communication system as recited in claim 1, wherein the first communication module is adapted to up-convert the first type of communication signal to the second type of communication signal.

19. A communication system as recited in claim 1, wherein the first communication module is adapted to down-convert the first type of communication signal to the second type of communication signal.

20. A communication system as recited in claim 1, wherein the second communication module is on the top of the building.

17. A communication system, comprising:

a first communication module adapted to;

receive a first type of communication signal, convert the first type of communication signal to a second type of communication signal and transmit the second type of communication signal to a second communication module;
