Trinity study confirms accuracy concerns on contact tracing apps

Trinity College Dublin:

A new measurement study released by Prof. Doug Leith and Dr Stephen Farrell, researchers at the CONNECT Centre in the School of Computer Science and Statistics at Trinity College Dublin, confirms that it is likely to be challenging to use Bluetooth to reliably detect when people using contact tracing apps are within 2m of one another.

The researchers took measurements in several locations in Dublin, in a supermarket, on board a train carriage, sitting around a meeting table, and walking outdoors on a city street and found problems with accurately measuring social distancing using Bluetooth wireless.
