CWDP: Certified Wireless Design Professional v303 — Question 21

What metric implements the simplest algorithm and lowest accuracy in networks requiring locations?

Answer options

• A. Angle of Arrival (AoA)
• B. Time of Arrival (ToA)
• C. Time Difference of Arrival (TDoA)
• D. Received Signal Strength Indicator (RSSI)

Correct answer: A

Explanation

Angle of Arrival (AoA) uses a straightforward method for estimating location, which results in lower accuracy compared to other metrics. Time of Arrival (ToA) and Time Difference of Arrival (TDoA) utilize more complex algorithms that yield better precision, while Received Signal Strength Indicator (RSSI) can also provide more reliable location estimates than AoA.
