Non-interfering multipath communication system
A non-interfering multipath communication technique establishes a base transmit and receive period for a variety of spaced apart transceiver devices of a base station and communicates between at least one field station and the base station through those transceiver devices; a period of the base station is allocated amongst the transceiver devices to maintain the non-interfering multipath communication between the at least one field station and the base station.
1. A non-interfering multipath communication system comprising:
a base station in communication with one or more field stations;
a plurality of transceivers spaced apart on the base station;
a controller in the base station, configured to allocate transmit and receive periods to each transceiver of the plurality of transceivers, each transceiver configured to transmit a synchronization signal during an allocated transmit period; and
a first field station of the one or more field stations configured to receive a synchronization signal transmitted by one transceiver of the plurality of transceivers during an allocated transmit period, and configured to transmit a status signal to the base station during an allocated receive period, wherein the base station compares at least two status signals received from the first field station to determine whether a path to the first field station is blocked.
2. The system of claim 1 , wherein the controller is further configured to define the transmit and receive periods using a base station clock.
3. The system of claim 1 , wherein the first field station further comprises a clock used to define transmit and receive periods, and at least one transceiver.
4. The system of claim 3 , wherein the field station clock is configured to synchronize with the base station clock responsive to receiving a base station synchronization signal.
5. The system of claim 1 , wherein the first field station further comprises a sensor.
6. The system of claim 1 , wherein the controller is further configured to randomly allocate transmit and receive periods amongst the plurality of transceivers.
7. The system of claim 1 , wherein the controller is further configured to allocate transmit and receive periods amongst the plurality of transceivers according to a predetermined order.
8. The system of claim 1 , wherein the base station is further configured to establish a non-interfering multipath communication between one or more of the base station transceivers and the first field station.
9. The system of claim 1 , wherein the first field station is further configured to retransmit a signal to a second base station transceiver after determining that a path to a first base station transceiver is blocked.
10. The system of claim 5 , wherein the status signal includes information obtained by the sensor.
11. The system of claim 1 , wherein the base station is further configured to listen on the plurality of transceivers for an incoming field station status.
12. A method for establishing a non-interfering multipath communication system, the method comprising:
allocating, by a controller in a base station, transmit and receive periods to each transceiver of a plurality of transceivers spaced apart on the base station;
transmitting, by at least one base station transceiver of the plurality of transceivers, a synchronization signal to a first field station during an allocated transmit period;
receiving, by the base station during an allocated receive period, a status signal transmitted by the first field station; and
comparing, by the base station, at least two status signals to determine whether a path to the first field station is blocked.
13. The method of claim 12 , further comprising defining, by the base station, transmit and receive periods using a base station clock.
14. The method of claim 12 , further comprising defining, by the first field station, transmit and receive periods using a field station clock.
15. The method of claim 14 , further comprising synchronizing the field station clock with the base station clock responsive to receiving a base station synchronization signal.
16. The method of claim 12 , wherein receiving the status signal further comprises receiving a status signal including information obtained by a sensor on the first field station.
17. The method of claim 12 , further comprising establishing a non-interfering multipath communication between one or more of the base station transceivers and the first field station.
18. The method of claim 12 , further comprising retransmitting, by the first field station, a signal to a second base station transceiver after determining that a path to a first base station transceiver is blocked.
19. The method of claim 12 , further comprising listening, by the base station transceivers, for an incoming field station status.
