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. 37 CFR 1.72(b).

Claims

1. A system comprising:

a source device operable to alternate between transmitting and not transmitting data for a plurality of successive time intervals that includes first, second and third time intervals, the source device transmitting on a first frequency during odd-numbered time intervals and not transmitting during even-numbered time intervals, a first block of data being transmitted during the first time interval, the source device ceasing transmission during the second time interval, and transmitting a second block of data during the third time interval;

a destination device; and

a plurality of wireless repeaters arranged to provide a pipelined data transmission link between the source device and the destination device, each of the repeaters having a transceiver coupled with a non-directional antenna, a first wireless repeater being operable to receive the first block of data from the source device during the first time interval, store the first block of data in a memory, and then transmit the first block of data within the second time interval, a second repeater within an in-band interference range of the source device being operable to receive the first block of date from the first wireless repeater during the second time interval, store the first block of data, and then transmit the first block of data within the third time interval on a second frequency that is non-interfering with respect to the first frequency,

wherein the first repeater receives and stores data in the memory during the odd-numbered time intervals, and transmits the stored data within the even-numbered time intervals.

2. The system of claim 1 wherein the second repeater receives and stores the data during the even-numbered time intervals and transmits the data using the second frequency during the odd-numbered time intervals.

3. The system of claim 1 wherein the destination device receives the first block of data from a last repeater in the pipelined data transmission link.

4. The system of claim 1 wherein the second frequency is in a 5 GHz frequency band.

5. A system comprising:

a source device that transmits data packets;

a destination device that receives the data packets;

a plurality of wireless repeaters configured to provide a pipelined data transmission link between the source device and the destination device in accordance with a transmission protocol, at least two of the wireless repeaters in the pipelined data transmission link being located within an in-band interference range of each other, each of the wireless repeaters having only a single transceiver coupled with a non-directional antenna, in accordance with the transmission protocol data throughput being maintained in the pipelined data transmission link as additional ones of the wireless repeaters are inserted in the network chain;

wherein the source device is operable to alternate between transmitting and not transmitting data packets for a plurality of successive time intervals, the source device transmitting during odd-numbered time intervals and not transmitting during even-numbered time intervals;

and wherein the destination device is located beyond an in-band interference range, yet within a maximum bandwidth range, of a last repeater in the network chain.

6. The system of claim 5 wherein at least one of the wireless repeaters transmits in a 5 GHz frequency band.

7. The system of claim 5 wherein each of the wireless repeaters transmits and receives in a 2.4 GHz frequency band.

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

9. A system comprising:

a source device operable to alternate between transmitting and not transmitting data for a plurality of successive time intervals, the source device transmitting on a first frequency during odd-numbered time intervals and not transmitting during even-numbered time intervals;

a destination device; and

a plurality of wireless repeaters arranged to provide a pipelined data transmission link between the source device and the destination device, each of the wireless repeaters having a transceiver coupled with a non-directional antenna, a first wireless repeater being operable to receive data during the odd-numbered time intervals and transmit data within the even-numbered time intervals, a second wireless repeater located within an in-band interference range of the source device being operable to receive a first block of data from the first wireless repeater during a second time interval, store the first block of data, and then transmit the first block of data within a third time interval using a second frequency that is non-interfering with respect to the first frequency, one or more of the wireless computers being located in the pipelined data transmission link beyond an in-band interference range, yet within a maximum bandwidth range, of a next wireless repeater in the pipelined data transmission link, and further

wherein at least one of the wireless repeaters includes;

an input/output (I/O) unit to receive encryption key information that authenticates use in the pipelined data transmission link; and

a ROM to store the encryption key information.

10. The system of claim 9 wherein at least one of the wireless repeaters further comprises a connector coupled to the I/O unit, the connector for receiving a wire plug coupled to an external device that provides encryption key information.

11. The system of claim 9 wherein at least one of the wireless repeaters further comprises an indicator panel that provides a visual indication of transmission signal strength, the indicator panel being coupled to the I/O unit.
