world where things are controlled from a distance is the reality of every day: according to a research observatory
"Internet of Things " at the Politecnico di Milano , Italy in 2013 objects connected via the cellular network or Wi-Fi -
except computers , phones and smartphones - they were 6 million , 20 percent more than the previous year . A
