Abstract

A method of pairing a first wireless access unit with a second wireless access unit in a mobile ad-hoc wireless pairing system includes determining that the second wireless access unit is available for pairing with the first wireless access unit and pairing the pairing the first wireless access unit with the second wireless access unit upon receiving an input from a user of the first wireless access unit. A location of the second wireless access unit is determined by adjusting a first wireless access unit weighting factor. The first wireless access unit weighting factor is adjusted until a threshold signal strength is received by the second wireless access unit. The first wireless access unit weighting factor is transmitted to the second wireless access unit, and feedback is received from the second wireless access unit. The feedback provides recommendations about the first wireless access unit weighting factor to the first wireless access unit.

Claims

1. A method of pairing a first wireless access unit with a second wireless access unit in a mobile ad-hoc wireless pairing system, the method comprising:

(a) determining that the second wireless access unit is available for pairing with the first wireless access unit;

(b) pairing the first wireless access unit with the second wireless access unit in response to receiving an input from a user of the first wireless access unit;

(c) determining a location of the second wireless access unit at least in part by adjusting a first wireless access unit weighting factor;

(d) adjusting the first wireless access unit weighting factor until a threshold signal strength is received by the second wireless access unit;

(e) transmitting the first wireless access unit weighting factor to the second wireless access unit; and

(f) receiving feedback from the second wireless access unit, wherein the feedback provides recommendations about the first wireless access unit weighting factor to the first wireless access unit.

2. The method of claim 1, further comprising:

(g) automatically re-establishing the pairing between the first and the second wireless access unit after a previous pairing connection between the first wireless access unit and second wireless access unit has been terminated.

3. The method of claim 1, further comprising:

(g) providing feedback to the second wireless access unit to adjust the second wireless access unit weighting factor until the first wireless access unit receives the threshold signal strength.

4. The method of claim 1, further comprising:

(g) receiving a selection from the user to pair the first wireless access unit with only the second wireless access unit; and

(h) adjusting the first wireless access unit weighting factor until the second wireless access unit receives the threshold signal strength and a non-cognizable signal is transmitted in a direction where the second wireless access unit is not located.

5. The method of claim 1, further comprising:

(g) receiving a selection from a user to pair the first wireless access unit with the second wireless access unit and the option of pairing with at least one other wireless access unit; and

(h) adjusting the first wireless access unit weighting factor until the second wireless access unit receives the threshold signal strength and a cognizable signal is transmitted in a direction where the second wireless access unit is not located..

6. A system for pairing a first wireless access unit with a second wireless access unit in a mobile ad-hoc wireless pairing system, the system comprising:

(a) a first wireless access unit having a first wireless access unit processor configured to control a first wireless access unit weighting factor and to facilitate transmission of the first wireless access unit weighting factor to the second wireless access unit; and

(b) a second wireless access unit having a second wireless access unit processor configured to control a second wireless access unit weighting factor and to facilitate the second wireless access unit weighting factor to the first wireless access unit, wherein;

(i) the first wireless access unit processor is configured to modify the first wireless access unit weighting factor to determine a location of the second wireless access unit and until the second wireless access unit receives a threshold signal strength;

(ii) the first wireless access unit is configured to receive an input from a user to pair the first wireless access unit with the second wireless access unit;

(iii) the second wireless access unit is configured to receive a signal from the first wireless access unit; and

(iv) the second wireless access unit processor is configured to provide recommendations about the first wireless access unit weighting factor to the first wireless access unit.

7. The system of claim 6, wherein the first wireless access unit processor is configured to automatically re-establish pairing between the first and the second wireless access unit after a previous pairing connection between the first wireless access unit and second wireless access unit has been terminated.

8. The system of claim 6, wherein the first wireless access unit processor is configured to provide feedback to the second wireless access unit to adjust the second wireless access unit weighting factor until the first wireless access unit receives the threshold signal strength.

9. The system of claim 6, wherein the first wireless access unit is configured to receive a selection from a user to pair the first wireless access unit with only the second wireless access unit, and wherein the first wireless access unit processor is configured to adjust the first wireless access unit weighting factor until the second wireless access unit receives a threshold signal strength and a non-cognizable signal is transmitted in a direction where the second wireless access unit is not located.

10. The system of claim 6, wherein the first wireless access unit is configured to receive a selection from a user to pair the first wireless access unit with the second wireless access unit and the option of pairing with at least one other wireless access unit, and wherein the first wireless access unit processor is configured to adjust the first wireless access unit weighting factor until the second wireless access unit receives a threshold signal strength and a cognizable signal is transmitted in a direction where the second wireless access unit is not located.
