Embodiment Construction

[0022] figure 1A simplified block diagram of an exemplary wireless device in the form of a BLE module 100 that can be used to implement the disclosed systems and methods is shown. As shown, the BLE module 100 includes a first module segment 110 that includes one or more central processing units (CPUs), processors or other programmable integrated circuits 150 and memory 155 with application data ( For example, DRAM). As shown, application(s) 212 may be executed by CPU 150 to provide multiple different wireless connections to other connected RF-enabled devices across different wireless connections (e.g., such as between different BLE wireless connections) Resources (eg, such as different Bluetooth services, security managers, parts of Bluetooth services such as Bluetooth service characteristics, and / or any other computing services or wireless operation services). Angle of Arrival (AoA) authentication 275 may be performed by the CPU 150, for example, to limit the binding or pai...

Abstract

The invention discloses systems and methods for initial authentication of wireless communication. 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.

Description

technical field [0001] The systems and methods disclosed herein relate to wireless communications, and more specifically, to initial authentication of wireless communications between wireless devices. Background technique [0002] Bluetooth Low Energy (BLE) refers to Bluetooth wireless radio technology. It is designed for low-power and low-latency applications in short-range wireless devices. Today, BLE applications can be found in healthcare, fitness, security, smart energy, industrial automation, and home entertainment. However, BLE is not limited to these, but more and more new applications using BLE technology are designed. [0003] The difference between BLE and Classic Bluetooth is that BLE devices consume significantly less communication power than traditional Bluetooth devices. Additionally, BLE is capable of initiating data transfers much faster than traditional Bluetooth. This makes it possible for BLE devices to constantly and intermittently communicate with o...
