Exam 300-430 topic 1 question 45 discussion

The angle of arrival (AoA) method determines the location of a wireless device based on the angle of incidence of the signal arriving at the access points (APs). Here’s how it works: Angle of Incidence: The AoA method calculates the direction from which a client device’s signal is received by measuring the angle at which the signal arrives at multiple APs. By combining the angles from at least two APs, the location of the client device can be determined using triangulation. How it works: Each AP measures the angle at which the client’s signal is received. These angles are then used to calculate the intersection point, which represents the client’s location.

D. angle of incidence

Provided answer is correct

Scratch my previous comment, D is the right answer according to Cisco - not wiki. Angle of Arrival (AoA) The Angle of Arrival (AoA) technique, sometimes referred to as Direction of Arrival (DoA), locates the mobile station by determining the angle of incidence at which signals arrive at the receiving sensor. Geometric relationships can then be used to estimate location from the intersection of two lines of bearing (LoBs) formed by a radial line to each receiving sensor, as illustrated in Figure 2-5. In a two-dimensional plane, at least two receiving sensors are required for location estimation with improved accuracy coming from at least three or more receiving sensors (triangulation).

I think the correct answer should be C. https://en.m.wikipedia.org/wiki/Angle_of_arrival
