What is 5G for?
January 23, 2021CNRS
As mobile operators offer the first 5G subscriptions to the general public, this new standard for telecommunications raises doubts and resistance. The CNRS senior researcher Philippe Owezarski presents the issues involved.
Philippe Owezarski, you are the director of the Trustworthy Computing Systems and Networks (RISC) department at the CNRS Laboratory for Analysis and Architecture of Systems (LAAS). Can you explain what is driving the transition to 5G?
Philippe Owezarski: The growing bandwidth needs of cellular networks – and hence for throughput –are the first reason for the generation change from 4G to 5G. Users, who are increasingly hooked on streaming to mobile devices, want to watch videos in 4K on their smartphones, even though this is of questionable interest given the size of the screen. This sustained demand and the saturation of 4G are fuelling the development of new services, especially for professionals.
