Quiz - Learning Nugget #2 These questions cover key principles and methods of indoor positioning discussed in the document. 1 / 5 What is "ranging" in the context of indoor tracking systems? The process of tracking objects in outdoor environments. Determining the distance between two objects using signals. Using GPS to track assets. A method to triangulate signals from satellites. 2 / 5 Which ranging method estimates distance based on signal power attenuation but is less accurate due to environmental factors? Time of Flight (ToF). Time Difference of Arrival (TDoA). Received Signal Strength Indicator (RSSI). Phase Difference of Arrival (PDoA). 3 / 5 What is the primary advantage of using Time of Flight (ToF) in indoor positioning systems? It does not require any synchronization between devices. It is the most affordable ranging method. It provides higher accuracy by measuring the time a signal takes to travel. It offers directional information using antennas. 4 / 5 How does trilateration differ from triangulation? Trilateration uses angles from two points, while triangulation uses distances from three or more points. Trilateration is only used in outdoor tracking, while triangulation is for indoor tracking. Trilateration relies on the strength of signals, while triangulation uses time measurements. Trilateration uses distances from three or more points, while triangulation uses angles from two points. 5 / 5 Which method determines the direction of a signal using an array of antennas? Angle of Arrival (AoA) and Angle of Departure (AoD) Time of Flight (ToF) Phase Difference of Arrival (PDoA) Received Signal Strength Indicator (RSSI) Thank you so much for participating in our quiz!
