Abstract 

RSSI measurements collected by four anchors while receiving messages from a single mobile node transmitting advertisement and extended advertisement messages in all BLE channels (both primary and secondary advertisement channels).  Tests conducted in 10x10 m office area (no large obstacles), with 4 anchors located in the corners of the area.

Instructions: 

Unzip the archive measurements.zip

The 'csv' folder contains 4 subfolders:

  • diag0 and diag1 - contain measurements along the diagonals of the area
  • inside - contains measurements along a rectangular grid of side 1m. Some points missing due to obstacles, i.e. desks
  • perimeter - contains measurements along the perimeter of the area

Each folder contains 4 CSV files named S0, S1, S2, S3. Each file contains measurements by a corresponding anchors.

Each CSV file contains a single header line and 7 columns:

  1. anchor - identifier of an anchors. It is the same as name of the file
  2. x - real X coordinate of the location where RSSI was measured
  3. y - real Y coordinate
  4. distance - real distance in meters from (x,y) location to the anchor
  5. distance_cm - real distance in centimeters (rounded)
  6. channel - BLE channel used for transmission
  7. RSSI - RSSI measurement on the channel used

Each line of a CSV file contains information about a single measurement collected.
