how we’ve grown
13 September 2020
Exactly two years ago to the day, our group had our very first operational experimental testbed (see News from Sept. 14th, 2018 below). At that time our group consisted of only two people (David, and Okky as an intern). Now we are 13-people strong with 7 operational testbeds. O how we’ve grown!
