Bluetooth Signal Strength Measurements

Introduction

We performed a series of measurements involving Bluetooth and the Active Bat system in order to understand propagation characteristics of Bluetooth in a typical office environment. The experiements were performed in the Digital Technology Group, Computer Laboratory, University of Cambridge.

We are making available selected data sets of the fine-grained measurements publicly so other researchers and interested parties may use the data. Data Sets Walls

The laboratory walls are given in the following file with the format:

x1

y1

x2

y2

The laboratory walls are contained within the coordinates:

(x = 990, y = 997) and (x = 1008, y = 1050)
