Thursday, in Culture Médias, 5G was again at the heart of the debates.

Jacques Moulin, managing director of IDATE DigiWorld, highlighted the technological progress made possible by this new mobile network, while Yves Marry, from the association "Lève tes eyes", is worried about ecological and health risks. , but also social. 

Should we be afraid of 5G?

While France launched the auction on Tuesday for the allocation of the first frequencies, part of public opinion remains suspicious, while left-wing elected officials and associations are calling for a moratorium.

Thursday, on Europe 1, the usefulness of this future mobile network was once again on the menu of debates, between Jacques Moulin, general manager of IDATE DigiWorld and Yves Marry, co-founder of the association "Lève tes eyes" , which raises awareness of the risks associated with screen overflow.

An "extraordinary revolution"? 

For Jacques Moulin, 5G is above all "an extraordinary revolution".

With this new network, "associated with robotics and the Internet of Things", we are going to witness "a real transformation of production chains, maintenance chains, and the very design of the solutions that can be provided for them. consumers ". 

DECRYPTION -

 Utility, competitiveness, health: three questions to understand 5G

5G, he continues, will be "a pledge of competitiveness and job creation for tomorrow", and allow very concrete developments, for example in the field of health.

In the event of an accident, "you sometimes have to play by the minute. Thanks to 5G, you will be able to transmit the radio, an ultrasound, which will be done with a mobile or another device, because 5G gives the possibility of transmit this data ". 

In addition, concludes Jacques Moulin, for Europe and France, the success of 5G is "a question of competitiveness and competitive advantage". 

Or a health and social and ecological danger?

Yves Marry, co-founder of "Lève tes eyes", prefers to highlight the "democratic problem" posed by 5G, because "the French do not want it and have expressed it through the Citizens' Convention", in which 98% of participants called for a moratorium.

An observation that Jacques Moulin does not share.

"The moratorium concerns especially the millimeter zones which are for 26 GHz, which will intervene much later", he answers.

For him, "there is no known danger on the airwaves currently in use". 

The fact remains that if it is a revolution which is being prepared with the arrival of 5G, "it would be good to agree", believes Yves Marry.

However, he adds, "there are a lot of doubts, health risks not yet elucidated, with a major ecological impact".

Ecologically, digital "represents 4% of greenhouse gas emissions. It is more than the aviation sector", advances Yves Marry, according to whom 5G "promises to be three times more energy efficient than 4G ".

“What is programmed for digital is 7.5% of emissions in 2025 when we should start a decline,” he still annoys.

And to conclude: "The urgency must be to preserve living things rather than always having to connect more".

An argument which, once again, does not convince its opponent.

"'The energy efficiency of 5G is ten times better than that of 4G," he said. 

Finally, continues Yves Marry, 5G also raises questions about "human attention", while the French "spend an average of 10 hours in front of a screen".

However, "the 5G project is to increase the connection on a daily basis".
