Systems And Methods For Initial Authentication Of Wireless Communication
First Claim
1. A method, comprising using at least one programmable integrated circuit of a first wireless device to determine whether to initially authenticate a wireless connection with a second wireless device based on a comparison between an angle of arrival (AoA) of a first wireless signal received from the second wireless device to a predefined range of allowable AoA values;
- and then to establish an authenticated wireless connection between the first and second wireless device only if it is determined to initially authenticate the wireless connection with the second wireless device.

Abstract
Systems and methods are provided that may be implemented to use angle of arrival (AoA) of a signal transmitted between two Bluetooth Low Energy (BLE) wireless devices to initially authenticate a connection between the two BLE devices. In one example, bonding or pairing with a first BLE device may be restricted to only those other BLE devices having an antenna currently positioned to transmit a signal to the first BLE device from an allowed direction and within a predefined permitted range of AoA relative to the first BLE device.

9. An apparatus, comprising at least one programmable integrated circuit coupled to radio circuitry and configured to be coupled to an antenna as a first wireless device, the at least one programmable integrated circuit being programmed to:
-
determine whether to initially authenticate a wireless connection with a second wireless device based on a comparison between an angle of arrival (AoA) of a first wireless signal received from the second wireless device to a predefined range of allowable AoA values; and then to establish an authenticated wireless connection between the first and second wireless device only if it is determined to initially authenticate the wireless connection with the second wireless device. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. A system, comprising:
-
a first wireless device and a second wireless device, the first wireless device including at least one programmable integrated circuit coupled to radio circuitry and an antenna, and the second wireless device including at least one programmable integrated circuit coupled to radio circuitry and an antenna; where the at least one programmable integrated circuit of the second wireless device is programmed to transmit a first wireless signal to the first wireless device; and where the at least one programmable integrated circuit of the first wireless device is programmed to; determine whether to initially authenticate a wireless connection with the second wireless device based on a comparison between an angle of arrival (AoA) of the first wireless signal received from the second wireless device to a predefined range of allowable AoA values, and then to establish an authenticated wireless connection between the first and second wireless device only if it is determined to initially authenticate the wireless connection with the second wireless device. - View Dependent Claims (18, 19, 20, 21)
