1. An access control method of a control unit, wherein the control unit determines whether a user has authority to access a target device corresponding to first device when a terminal carried by the user is located in a predetermined range, wherein the terminal is configured to obtain signals emitted by the first device, and wherein the first device comprises first antenna and second antenna, the access control method comprising:
obtaining an angle of departure of the signals at the first device based on first and second signals, wherein the first signal is emitted by the first antenna and the second signal is emitted by the second antenna, and wherein a terminal antenna of the terminal configured to receive the first and second signals when the terminal receives the signals from the first antenna and the second antenna;
determining whether the terminal is located in the predetermined range based on the angle of departure; and
performing authentication of the user as authorized to access the target device based on the terminal being located in the predetermined range.
