The walls of the chambers are covered by material that absorbs electromagnetic radiation and prevents it from bouncing back off the walls (hence "anechoic"). The large chambers hold all the necessary equipment used to measure the transmission and reception of electromagnetic waves, for communication between vehicles, between vehicles and their surroundings, and through the windows of buildings. This will become increasingly necessary in the future with the advent of 5G and self-driving vehicles.

The investment of around 10 million euros, with support from the Walloon government, will also serve as a technology platform for various players involved in the challenge of connectivity in Wallonia, including the public authorities together with various industries such as transport, construction, telecommunication etc. The new facility will create around 20 jobs.
