Description


Round-trip Time-of-flight Measurements from a supermarket

The dataset is meant to aid development and evaluation of indoor location in complex indoor environments using round-trip time-of-flight (RToF) and magnetometer measurements. The dataset provides Round-trip time-of-flight (RToF) and magnetometer measurements at 1589 mobile node locations from 30 deployed stationary anchors in the 26m x 24m New Wing Yuan supermarket in Sunnyvale, CA. The data was collected during working hours over a period of 15 days. The nodes are equipped with chirp spread spectrum Nanotron nanoLoc radios (802.15.4a) and a Honeywell's HMC5843, a 3-axis digital magnetometer. At every location, 20 distinct readings were obtained for RToF signatures as well magnetometer measurements, to capture the variance, giving a total of 31780 readings. ; apurohit@ece.cmu.edu
