Abstract

A method for radio frequency transmitting and receiving beamforming using both GPS guidance and wireless access points is disclosed. The method comprises providing a wireless networking device with preloaded wireless access point locations; calculating a relative vector to an access point based upon at least one of the preloaded wireless access point locations; steering a transmitted beam with a sounding packet to the access point; calculating a channel condition by the access point; and sending a packet by the access point to the wireless networking device to establish a connection.

Claims

1. A method for using beamforming to establish a wireless connection, comprising:

providing a wireless networking device with a plurality of preloaded wireless access point locations;

calculating a relative vector to an access point based upon at least one of the preloaded wireless access point locations;

steering a transmitted beam with a sounding packet to the access point;

determining a channel condition by the access point based upon the received channel condition; and

sending a packet by the access point to the wireless networking device to establish a connection if the channel condition is acceptable.

2. The method of claim 1 further including:

providing the wireless networking device with a global positioning system (GPS) and an electronic compass.

3. The method of claim 2 further including:

calculating the relative vector utilizing the compass and the GPS to establish the wireless networking device location.

4. The method of claim 1 wherein steering the transmitting beam comprises initiating a searching algorithm based on the calculated relative vector.

5. A computer readable medium containing programming instructions for using beamforming to establish a wireless connection, the instructions being executable for:

providing a wireless networking device with a plurality of preloaded wireless access point locations;

calculating a relative vector to an access point based upon at least one of the preloaded wireless access point locations;

steering a transmitted beam with a sounding packet to the access point;

determining a channel condition by the access point based upon the received channel condition; and

sending a packet by the access point to the wireless networking device to establish a connection if the channel condition is acceptable.

6. The computer readable medium of claim 5 further including the instructions for:

providing a wireless networking device with a global positioning system (GPS) and an electronic compass.

7. The computer readable medium of claim 5 further including the instructions for:

calculating a relative vector utilizing a compass and a GPS to establish the wireless networking device location.

8. The computer readable medium of claim 5 further including the instructions for:

initiating a searching algorithm based on the calculated relative vector.

9. A system comprising:

a wireless networking device for receiving and transmitting information;

an electronic compass;

a global positioning system (GPS); and

a plurality of preloaded wireless access point locations, wherein the GPS, electronic compass, and preloaded wireless access point locations work in cooperation to identify at least one access point for a connection.

10. The system of claim 9 wherein upon receiving the information regarding each new access point, the wireless networking device calculates a relative vector to the access point;

wherein based on the relative vector to the access point, the wireless networking device steers a transmitting beam and a sounding packet to the access point;

wherein the access point sends a packet to the wireless networking device and a connection is thereby established.
