Abstract

A smart antenna apparatus includes a casing, which supports an omnidirectional antenna array; a plurality of transceivers electrically connected with the antenna array; and a format converter and booster device electrically connected between the plurality of transceivers and a network port, said format converter and booster device comprising a multiplexer/de-multiplexer circuit for encoding plural USB signals from the plurality of transceivers to the network port and for decoding plural USB signals from the network port to the plurality of transceivers.

Claims

1. A secure wireless networking system comprising:

a local router configured to establish a virtual private network with a remote router, said local router disposed within a secure facility and comprising a first format converter and booster device, said first format converter and booster device comprising;

a plurality of USB ports connected in communication with the router processor;

a network port; and

a multiplexer/de-multiplexer circuit for encoding plural USB signals from the USB ports to the network port, and for decoding plural USB signals from the network port to the plurality of USB ports;

a smart antenna disposed without the secure facility and comprising a second format converter and booster device, a plurality of transceivers, and at least one antenna per transceiver, said second format converter and booster device comprising;

a second network port; and

a second multiplexer/de-multiplexer circuit for encoding plural USB signals from the plurality of transceivers to the second network port, and for decoding plural USB signals from the second network port to the plurality of transceivers; and

a network cable connected through a boundary of the secure facility between the network port of the first format converter and booster device within the local router and the second network port of the second format converter and booster device within the smart antenna.

2. The system as claimed in claim 1, wherein the router processor splits an outgoing data stream among more than one of the plurality of USB ports, and compiles an incoming data stream from more than one of the plurality of USB ports.

3. The system as claimed in claim 1, wherein the multiplexer/de-multiplexer at the local router and the second multiplexer/de-multiplexer at the smart antenna encode and decode in such a manner as to maintain one-to-one signal correspondence among the plurality of USB ports at the local router and the plurality of transceivers at the smart antenna.

4. The system as claimed in claim 1, wherein the multiplexer/de-multiplexer at the local router and the second multiplexer/de-multiplexer at the smart antenna encode and decode in such a manner as to shuffle signal packets among the plurality of USB ports and the plurality of transceivers.

5. The system as claimed in claim 4, wherein the shuffling of signal packets includes buffering.

6. The system as claimed in claim 1, wherein at least one of the plurality of transceivers is configured to operate in a different signal frequency from at least one other of the plurality of transceivers.

7. The system as claimed in claim 1, wherein the multiplexer/de-multiplexer circuits encode the USB signals onto a carrier power signal.

8. The system as claimed in claim 1, wherein the multiplexer/de-multiplexer circuits encode the USB signals in parallel with mode-of-control signals to and from the transceivers.

9. The system as claimed in claim 1, wherein the network cable is an AC power cable connected to the network ports via powerline network adapters.
