Marconi: The visionary

“I think I am safe in saying that if radio has already done so much for the safety

• f

life at sea, for commerce, and for commercial and military communications it is also destined to bring new and, until recently, unforeseen

• pportunities

for healthy recreation and instruction into the lives of millions

• f human beings.”

[Guglielmo Marconi, 1922]

Forecasting Entertainment in 1922

Broadcasting [...] is not

• the

most significant part of modern communications, in so far as it is a one way communication. A far greater importance attaches, in my opinion, to the possibility afforded by radio of exchanging communications wherever the correspondents may be situated: whether in mid-ocean, or on the ice pack of the pole, or in the waste of a desert, or above the clouds in a airplane!

Localization, C‐V2X and distributed processing for beyond 5G

• Active and Passive localization (D. Dardari):
• Ultra‐wide bandwidth (UWB) technologies
• Crowd‐based learning and tracking algorithms
• mm‐wave beamforming (5G initial access, single‐anchor localization)
• Environment radio mapping  Crowd mapping and personal radar

for “mapless” and “infrastructureless” localization

• Backscatter passive communication and power transfer
• Simultaneously Localization and Mapping (SLAM)
• 5G technologies for connected self‐driving cars (B. Masini – A. Bazzi): performance

evaluation of Cellular‐Vehicle to Everything (C‐V2X) and hybrid communications for future vehicular scenarios

• Consensus algorithms (G. Pasolini – F. Zabini): computation of globally relevant statistics

exploiting only local communications among sensors applied to spectrum sensing, cooperative driving, drone formation and environmental monitoring.

Networks ethics

1927: Alfred North Whitehead

• Creativity is the universal of universals
• Creativity is the ultimate principle by which the many, which are

the universe disjunctively, become the one actual occasion, which is the universe conjunctively

=> Creativity is the ultimate metaphysical principle!
