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

Contributed by Aveek Purohit, Shijia Pan, Kaifei Chen, Zheng Sun, Pei Zhang.

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.

Cheers,
Tristan
