Locating rate adaptation by evaluating movement specific parameters

Abstract

We introduce different techniques, to adapt the update rate of a Real Time Locating System (RTLS) using Angle of Arrival (AoA) and Round Trip Time (RTT). A dedicated algorithm is implemented to detect the speed of walking of a person by exploiting data on the steps from a 3-dimensional accelerometer. Its implementation is described and the results of two experiments are discussed demonstrating the gain of the adaptation in terms of an increased channel capacity.
