Vodafone was the first Italian provider to open the 5G network in four cities on June 16th. The others will be arriving shortly and the signal is clear: Italy has entered the 5G era, at least from the point of view of the network offer.

We are therefore: we will see a growing number of announcements, declarations, proposals, considerations, ongoing analyses, first disservices, sector initiatives.

In this sense, it is already time to take stock of the state of the network with whom the network, in the broad sense, has helped to build it in Italy: we are talking about Joy Marino, president of Mix company that manages and coordinates the methods of peeling among most

In an interview Marino expressed with us about all 5G, except the value of the trials. •No comment • he told us at the request of an evaluation of the pilot projects carried out in Italy. For the rest we have addressed the issues of backhaul, or what will happen to them, latency,…edge and the SMEs, security and health.

What impact will 5G have on backhaul networks?

Significant, no doubt. It will be mainly in terms of capillaries rather than strengthening the transmissive band. With a little imagination I can imagine that to tend there will be a fiber ending (1 Gbps) for a 5G station every 4-5 doors of access in fiber of fixed users, with the same geographic distribution. This means reviewing the definition itself of what we mean by backhaul.

Latency and cloud: how much edge will we have and with what growth curve in the medium term?

We’ll have more and more edge, so the world of networks goes. We must realise that content caches, as well as multicasting appliances, are now essential elements of network infrastructure, they are no longer just components of the Cloud Computing IT infrastructure. The next step will be the virtualization of these appliances in NFV mode (Network Function Virtualization); it is a paradigm change

Security issue: with 5G increase the fronts of attack? How’s he getting out? What strategy?

For the end user, it does not change much: the risks are proportional to the number of devices and apps that are used, and especially to their……………………. I will never tire of repeating that security is a matter of ‘end-to-end’, you cannot and you must not rely on those who only transport bits. Other considerations apply to operators, because the war (cold) between the US and China may cause some victims, perhaps hit by the fire of friends.

How much is mobile video traffic weighing now and how much will it weigh with 5G?

There is a general trend towards increasing on-line average consumption, measured in number of minutes of use per week. Translated: we use our smartphone more and more to inform and entertain us. Some physical limitations seem to me to be there: in 24 hours there are other essential activities and \\’not compressible \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\ I may be an all-time old man, but I still believe that mobile traffic will never reach the volumes conveyed by the fixed network (including WiFi and the like).

Let us address the health issue. In Switzerland, an Orthodox opinion movement is being formed, calling for a real fact checking on the risks of 5G. We Italians have a softer attitude. Can the problem exist?

Measuring risks is a difficult, very difficult job, like all those who have to do with calculating odds. I find it very easy to use the precautionary principle (expressed as: If we had always applied it, perhaps the Romans would never have used lead-coated glazes in the dishes, but we would still live in the caves.

Collecting large-scale epidemiological data is difficult, but it is not much more than what the many data miners do that grind our identities and trample our privacy day by day. I certainly trust science more than empirical thought; like what, for example, asked us to turn off WiFi in schools, without making any problem of the use of smartphones by our children. Just to understand: WiFi = 100 mW on the area of a school, GSM/3G/4G in transmission = some W near the brain. 5G will be omnipervasive, but the powers in the circle will be much closer to those of WiFi than those of previous cellular networks.

Pragmatically the typical Pmi of Italian manufacturing what should be expected from 5G? Perhaps a new round of investments in network infrastructure?

There will certainly be psychological pressure from operators and technology suppliers to adopt 5G, but I do not think that it will be strictly necessary to chase the technology and invest in advance. If there is one thing that has made the Internet sovereign in this complex world, it is interoperability: both between operators and between applications and devices, and, in this case, with the recent past and the near future. There is no obligation to chase the latest technology, at least until the territorial coverage of 5G is predominant. If I may be allowed to compare, the technology user, whether it be an SME or a family, should not be so concerned about when the new technology (FTTH, 5G) will begin to be available, as about when the old technology (copper, 3G) will The

So, is Italy ready for 5G?

On the side of the offer I think it is true: the major operators have done their experiments and have well-structured investment plans. They’re warming up the engines. I think there are still a few unknowns. The cycle with which smartphones are aged and replaced is always fast, but the lack of economic growth can have its weight, at least in the short term. In addition, beyond the great communication batage, if there will be any specific 5G killer application we will discover only ex-post.
