Abstract

A microwave system comprises an antenna, antenna feed, a radio transceiver, and appropriate cabling among the aforementioned. Cost, performance and reliability improvements are achieved with further integration of these elements and with design improvements in the antenna feed. One improvement is the integration of the radio transceiver with the antenna feed. This improvement has many benefits including the elimination of RF cables and connectors. Another improvement is the utilization of the digital cable to power the integrated radio transceiver and a center fed parabolic reflector. One embodiment is disclosed for a radio gateway supporting OSI layers 1-7 supported by an Ethernet cable. Another embodiment is a radio with a client controller suitable for supporting OSI layers 1-3, and supported by a USB cable.

Claims

1. A microwave system comprising:

a center fed parabolic reflector.

a radio transceiver; and

a client station

wherein the radio transceiver is physically integrated with the center fed parabolic reflector, wherein the radio transceiver receives power through a digital cable, and wherein the digital cable is coupled to the client station.

2. The system of claim 1 wherein the digital cable is an Ethernet cable.

3. The system of claim 2 wherein the radio transceiver couples to a passive adapter via the Ethernet cable, which in turn the passive adapter couples to a client station via another Ethernet cable, wherein the passive adapter receives power by a USB cable that is coupled from the client station;

whereas the passive adapter injects power into the Ethernet cable that is coupled to the radio transceiver.

4. The system of claim 3, wherein the radio transceiver comprises a radio gateway supporting OSI layers 1 to 7.

5. The system of claim 1 wherein the digital cable is a USB cable.

6. The system of claim 5 wherein the radio transceiver couples to a USB repeater via the USB cable, which in turn the USB repeater couples to a client station via another USB cable, wherein the length of the USB cables is selected such that there is sufficient power to support the operation of the radio transceiver

7. The system of claim 6, wherein the radio transceiver comprises a client controller supporting OSI layers 1 to 3.

12. The method of claim 1 wherein the digital cable is a USB cable.

13. The method of claim 12 wherein the radio transceiver couples to a USB repeater via the USB cable, which in turn the USB repeater couples to a client station via another USB cable, wherein the length of the USB cables is selected such that there is sufficient power to support the operation of the radio transceiver.

14. The method of claim 13 wherein the radio transceiver comprises a client controller, supporting OSI lay ers 1 to 3.

8. A method of powdering a microwave system, the method comprising the steps of:

integrating a radio transceiver into a center fed parabolic reflector;

coupling a digital cable from a client station to the radio transceiver; and

supplying power from the client station to the radio transceiver over the digital cable;

wherein the digital cable also provides a baseband signal to the radio transceiver.

9. The method of claim 8, wherein the digital cable is an Ethernet cable.

10. The method of claim 9, wherein the radio transceiver couples to a passive adapter via the Ethernet cable, which in turn the passive adapter couples to a client station via another Ethernet cable, wherein the passive adapter receives power by a USB cable that is coupled from the client station;

whereas the passive adapter injects power into the Ethernet cable that is coupled to the radio transceiver.

11. The method of claim 10, wherein the radio transceiver comprises a radio gateway supporting OSI layers 1 to 7.

15. A microwave system comprising:

a center fed parabolic reflector;

a radio transceiver; and

a client station

wherein the radio transceiver is located between the client station and the center fed parabolic reflector, and is powered over an digital cable coupled to the client station.
