Two press articles on the Terahertz revolution mention the IEMN, its partners and one of its researchers, Guillaume Ducournau, a professor at the University of Lille and a specialist in wireless telecommunications.

Terahertz, promising waves for non-invasive monitoring, medical applications and telecommunications

"Wireless networks are under increasing pressure to deliver greater volumes of data to users. What's more, for new uses, such as real-time remote surgery or autonomous vehicles, these networks will need to have zero latency, which means drastically increasing their throughput. Terahertz waves would be the solution of choice". (extract from the article in The ResearchNo. 561-562, July-August 2020)

Guillaume Ducournau in The Research Fibre optics, mobile telephony (3G, 4G, 5G, etc.), wi-fi: all these telecoms technologies are designed to interconnect us. The technology used depends directly on the location of the transmitter and receiver. For example, on a fibre-optic network, the transmitter and receiver are fixed; this mainly corresponds to global network cores (submarine networks), fixed communications between major cities, and now covers homes gradually connected to fibre. The main purpose of cellular networks (3G, 4G, 5G) is to link portable receivers to a base station (antenna), managing a geographical area of 1 km (urban areas) to 10 km (less dense areas) on average, with performance depending greatly on location, geography, building density, etc. Wi-fi networks manage shorter-distance communications, on the scale of a small building, a train, etc., using radio waves. LiFi, which uses light transmitted through the air, also makes it possible to cover several fixed users in a meeting room, with greater speed than wi-fi.
