UWB measurement data


I believe that your theory needs realism by being involved and being in close touch with experimentalists... Don't stray far from the experiments if you are working on theory, and if you have talent for experiments, do them."  
Hermann A. Haus,
Institute Professor, MIT


To download the UWB measurement data file, please click here. The zip-file contains UWB measurement data taken by Prof. Moe Z. Win in 1995. Measurements are provided in 3 locations:
  • Room P, at typical high SNR,
  • Room H, at typical low SNR, and
  • Room B, at typical extremely low SNR.

At every location, 49 measurements were taken on a 7 x 7 grid. Additional technical details regarding the measurements (including a map) may be found in the two references below.

File formats

The zip-file contains 3 directories, one for each of the 3 rooms. Each directory contains 50 files: one file for each of the 49 measurement points, and an additional file used for calibration. Every filename ends with two numbers indicating the position in the grid at which the measurement was taken. For instance, a file ending with "13.DAT" corresponds to a measurement taken at position (1,3) on the 7 x 7 grid. The name of the calibration file ends with "99.DAT".


The measurements are provided as-is without any guarantees. The data is provided free of charge, and may be used for non-commercial, non-profit use only, provided the above references are properly cited. Additional measurements may be obtained by sending an e-mail to wgroup (at) mit dot edu.
