Abstract

A signal repeater system in a repeater unit having a repeater receiver, a repeater transmitter, a controller, a power source, and an optional network interface. The repeater unit performs an authentication of security codes contained in the received communication signals. If validly authenticated, the repeater unit retransmits the communication signals to a barrier operator. The transmitted communication signals may also contain predetermined functions that allow a remote transmitter to actuate an access barrier, such as a garage door opener, via the barrier operator. As such, the repeater system extends the effective range of the remote transmitter, allowing a user to actuate the barrier operator from a greater range. An optional network interface provided by the repeater unit, allows the repeater unit to be connected to any computer network. Accordingly, a remote host can access certain data content and invoke certain functions.

Claims

1. A repeater unit to retransmit communication signals received from a remote transmitter comprising:

a repeater receiver having a receiver antenna to receive the communication signal;

a controller adapted to store and authenticate the received communication signal;

a repeater transmitter having a transmitter antenna, said repeater transmitter coupled to said controller, wherein said repeater transmitter retransmits said stored communication signal if said communication signal is authenticated by said controller.

2. The repeater unit according to claim 1, wherein said repeater transmitter retransmits said stored communication signal during a dead-time period.

3. The repeater unit according to claim 1, wherein said stored communication signal is retransmitted until said repeater receiver receives a validation signal from a device receiving said retransmitted communication signal.

4. The repeater unit according to claim 3, wherein said validation signal comprises a light fixture command signal.

5. The repeater unit according to claim 1, further comprising:

an indicator connected to said controller.

6. The repeater unit according to claim 5, wherein said indicator identifies an operational status of said repeater unit.

7. The repeater unit according to claim 1, further comprising a selector connected to said controller.

8. The repeater unit according to claim 7, wherein said selector enables a learn mode provided by said repeater unit.

9. The repeater unit according to claim 1, further comprising a network interface connected to said controller to enable connection of the repeater unit to a computer network.

10. The repeater unit according to claim 9, wherein said network interface comprises an Ethernet adapter.

11. The repeater unit according to claim 9, wherein said network interface comprises a wireless interface.

12. A method of retransmitting a received communication signal from a remote transmitter comprising:

providing a barrier operator having a communication signal reception range;

providing a repeater unit having a communication signal transmission range;

positioning said repeater unit relative to said barrier operator, such that said communication signal transmission range of said repeater unit overlaps said communication signal reception range of said barrier operator;

transmitting a communication signal from a remote transmitter to actuate said barrier operator;

receiving said transmitted communication signal at said repeater unit;

storing said transmitted communication signal at said repeater unit;

authenticating said communication signal at said repeater unit to determine if said communication signal originates from said learned remote transmitter; and

retransmitting said communication signal to said barrier operator by said repeater unit if said repeater unit validates said communication signal at said authenticating step.

13. The method according to claim 12, further comprising:

receiving said communication signal;

storing and authenticating said communication signal received by said repeater receiver in a controller; and

retransmitting said authenticated communicational signal by a repeater transmitter coupled to said controller.

14. The method according to claim 13, further comprising:

providing an indicator coupled to said controller, so as to identify the status of said repeater unit.

15. The method according to claim 13, further comprising:

providing a selector coupled to said controller; and

enabling a learn mode of said repeater unit by actuating said selector.

16. The method according to claim 13, further comprising connecting a network device to a network interface provided by said controller.

17. The method according to claim 16, wherein said network interface comprises an Ethernet adapter.

18. The method according to claim 16, wherein said network interface comprises a wireless interface.

19. The method according to claim 12, further comprising:

including a security code unique to said remote transmitter in said communication signal.

20. The method according to claim 12, further comprising:

performing the retransmitting step during a dead-time period.

21. The method according to claim 12, further comprising:

repeating said retransmitting step until said repeater unit receives a verification signal transmitted from said barrier operator.
