Abstract:
It is presented a method for determining whether a portable key device is located in an active area in relation to a barrier. The method is performed in an access control device and comprises the steps of: detecting an angle of arrival of a wireless signal from the portable key device using a pair of antennas provided such that a line between the pair of antennas crosses the barrier; and determining whether the portable key device is located within the active area based on the angle of arrival.
