Abstract

A network for wireless transmission of data includes a source access point, a destination device and a plurality of wireless repeaters that provide a transmission link between the source access point and the destination device. The plurality of access points each includes a single transceiver with separate transmitter and receiver sections operable to simultaneously transmit and receive data on different frequency channels. It is emphasized that this abstract is provided to comply with the rules requiring an abstract that will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.

Claims

1. A wireless network comprising:

a source device;

a destination device; and

a plurality of repeaters to provide a pipelined data transmission link between the source device and the destination device, even numbered repeaters in the pipelined data transmission link having a transceiver that receives on one frequency channel and switches to another frequency channel to transmit, odd numbered repeaters in the pipelined data transmission link having a transceiver that receives and transmits on a single frequency channel, each of the repeaters being located beyond an in-band interference range, yet within a maximum bandwidth range, of adjacent repeaters in the pipelined data transmission link.

2. The wireless network of claim 1 wherein a first repeater in the pipelined data transmission link is located beyond the in-band interference range, yet within the maximum bandwidth range, of the source device.

3. The wireless network of claim 2 wherein the source device transmits data packets on a first channel and the first repeater receives and re-transmits the data packets on the first channel.

4. The wireless network of claim 3 wherein the destination device is located beyond the in-band interference range, yet within the maximum bandwidth range, of a last repeater in the pipelined data transmission link.

5. The wireless network of claim 4 wherein the destination device receives the data packets on a second channel and the last repeater receives and re-transmits the data packets on the second channel.

6. The wireless network of claim 1 wherein the source and destination devices operate in a 2.4 GHz frequency band.

7. The wireless network of claim 1 wherein each of the plurality of repeaters transmits and receives in a 2.4 GHz frequency band.

8. The wireless network of claim 6 wherein a first repeater in the pipelined data transmission link receives data packets from the source device in the 2.4 GHz frequency band and re-transmits the data packets in a 5 GHz frequency band, and a last repeater in the pipelined data transmission link receives the data packets in the 5 GHz frequency band and re-transmits the data packets to the destination device in the 2.4 GHz frequency band.
