LIMITING WIRELESS DISCOVERY RANGE
First Claim
Patent Images
1. A method comprising:
- determining, at a first device, a discovery range threshold that limits a distance from the first device at which a second device is operative to decode a discovery message;
adjusting a transmission attribute at the first device based on the discovery range threshold; and
sending the discovery message in accordance with the adjusted transmission attribute.

Abstract
Systems and methods of limiting wireless discovery range are described. A method may include determining, at a first device, a discovery range threshold that limits a distance from the first device at which a second device is operative to decode a discovery message. The method may include adjusting a transmission attribute at the first device based on the discovery range threshold. The method may include sending the discovery message in accordance with the adjusted transmission attribute.

15. A method comprising:
-
receiving at a second device a discovery message from a first device; determining a distance between the second device and the first device based on at least one attribute of the discovery message; based on determining that the distance is within a discovery range threshold, processing the discovery message; and based on determining that the distance is outside the discovery range threshold, discarding the discovery message. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23)
