An access control device according to one embodiment includes an access control mechanism, a housing, an antenna array secured within the housing and including a first, second, and third antenna adapted to radiate away from the exterior side of the door, a processor, and a memory. The memory includes a plurality of instructions that, when executed, causes the access control device to determine signal strengths of signals received by the first, second, and third antennas from the mobile device, determine whether a location of the mobile device relative to the access control device is indicative of the mobile device user's intent to access the passageway based on the signal strengths, and automatically unlock the access control mechanism in response to the location being indicative of the user's intent to access the passageway.
