The correct answer is D. angle of arrival.

Angle of Arrival (AoA) is a technique used in wireless communication systems to determine the direction from which a signal is transmitted. In the context of client tracking, AoA can be used to determine the location of a wireless device by measuring the angles at which signals from the device are received by multiple access points (APs).

When a wireless device transmits a signal, it generates a radio wave that travels through the air and is received by nearby APs. The APs can then use the information in the received signal to determine the direction from which the signal originated.

To determine the location of a wireless device using AoA, multiple APs are needed to receive the signals from the device. By measuring the angle at which each AP receives the signal, it is possible to calculate the location of the device using triangulation.

Triangulation is a technique that uses the angle measurements from multiple APs to determine the location of a wireless device. By comparing the angle measurements from different APs, it is possible to calculate the location of the device using trigonometry.

In summary, the angle of arrival method uses the direction from which a signal is transmitted to determine the location of a wireless device. Multiple access points are used to receive signals from the device and measure the angle of arrival. The angles are then used to calculate the location of the device using triangulation.
