Self-configuring, adaptive, three-dimensional, wireless network
View Patent ↗A network for wireless transmission of a media data in a building includes a plurality of access points. A first access point receives the media data from a source and transmits the media data downstream at a first data rate. A plurality of additional access points is distributed about the building, each of which includes an upstream transceiver to receive the media content on a first channel and a downstream transceiver to re-transmit the media content at substantially the first data rate on a second channel. 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.
1. A wireless access point comprising:
a plug for insertion into an electrical outlet;
a power supply unit coupled to the plug for converting an A.C. voltage provided by the electrical outlet into a D.C. voltage;
at least one wireless transceiver powered by the D.C. voltage, the at least one wireless transceiver being configured to receive a digital data stream as a pipeline of packets in a first frequency band, each packet being received during an odd time interval of a sequence of intervals, each time interval of the sequence being of equal duration, the at least one wireless transceiver being further configured to buffer each packet in a memory, and then re-transmit each packet in the first frequency band over a distributed wireless repeater network at a data rate of 11 Mbps or greater during a subsequent even time interval, the at least one wireless transceiver not transmitting during the odd time intervals;
a housing, the power supply unit and the at least one wireless transceiver being enclosed within the housing, the plug being attached to the housing such that the electrical outlet physically supports the wireless access point in a position against the electrical outlet when the plug is inserted into the electrical outlet; and
a processor that executes a computer program to configure frequency channels used for receiving and re-transmitting the one or more digital data packets in accordance with a combination of frequency channels that provides an optimum data throughput across the distributed wireless repeater network.
2. The wireless access point of claim 1 wherein the processor, when executing the computer program, is further operable to dynamically re-configure the frequency channels used for receiving and re-transmitting the one or more digital data packets responsive to changes in the wireless network or any disturbance or channel conflict that causes signal transmissions to fall below a threshold value.
3. The wireless access point of claim 1 wherein the at least one wireless transceiver comprises a device compliant to an IEEE 802.11 standard.
4. The wireless access point of claim 1 wherein the at least one wireless transceiver receives and re-transmits each packet on a single frequency channel of the first frequency band.
5. The wireless access point of claim 1 wherein the at least one wireless transceiver receives each packet on a first frequency channel of the first frequency band and re-transmits each packet on a second frequency channel of the first frequency band.
6. The wireless access point of claim 1 wherein each packet comprises audio data.
7. The wireless access point of claim 1 wherein each packet comprises video data.
8. A wireless access point comprising:
a housing;
a plug fixedly attached to the housing for insertion into an electrical outlet, the electrical outlet physically supporting and powering the wireless access point;
at least one transceiver for wirelessly receiving one or more data packets of a digital data stream during a first time interval of a sequence of intervals, and wirelessly re-transmitting over a distributed wireless repeater network the one or more data packets at a data rate of 11 Mbps or greater during a second time interval delayed by one interval from the first time interval, the at least one transceiver being enclosed within the housing;
a port independent from the electrical outlet that provides a physical data interface; and
a processor that executes a computer program to configure frequency channels used for receiving and re-transmitting data in accordance with a combination of frequency channels that provides an optimum data throughput across the distributed wireless repeater network.
9. The wireless access point of claim 8 wherein the physical data interface comprises an IEEE 1394 interface.
10. The wireless access point of claim 8 wherein the physical data interface comprises an optical interface.
11. The wireless access point of claim 8 wherein the at least one transceiver receives and re-transmits the one or more data packets on a single frequency channel.
12. A wireless access point comprising:
a housing;
a plug fixedly attached to the housing for insertion into an electrical outlet, the electrical outlet physically supporting and powering the wireless access point;
means enclosed in the housing for repeating audio/video data repeated from another wireless access point at a data rate of 11 Mbps or greater, the means and the another wireless access point communicating on a single frequency channel, the means comprising at least one wireless transceiver that receives one or more digital data packets during an odd time interval of a sequence of intervals, each time interval of the sequence being of equal duration, buffers the one or more digital data packets in a memory, and then re-transmits the one or more digital data packets over a distributed wireless repeater network during a next even time interval, the at least one transceiver not transmitting during the odd time interval; and
a port independent from the electrical outlet that provides a physical data interface coupled to the at least one wireless transceiver.
