Abstract: Systems and methods for detecting and protecting against phase manipulation during AoA or AoD operations are disclosed. For AoA operations, the network device receiving the constant tone extension (CTE) generates an antenna switching pattern, which may be randomly generated. The network device then receives the CTE using a plurality of antenna elements. In one embodiment, the network device compares the phase of portions of the CTE signal received that utilize the same antenna element. If the phase of these portions differs by more than a threshold, the network device detects a malicious attack and acts accordingly. In another embodiment, if the AoA algorithm cannot determine the angle of arrival, the network device detects a malicious attack and acts accordingly. For angle of departure operations, the network device that transmits the CTE signal generates the antenna switching pattern and transmits it to the position engine, which performs the comparisons described above.
