Fewer and fewer PCs and more and more tablets and smartphones, but how much does the wireless Internet cost us? The consumption of power of the wireless networks it is much higher than wired networks, not to mention the ultra-broadband LTE dedicated to mobile devices. This means that, in the face of the mass shift towards connections wireless we will consume more and more power and we will pollute more to produce it.
With the Internet more and more wireless, working on the net or playing Candy Crush will cost us more in terms of consumption of power. Audiweb Mobile, the new online audience survey system created by Audiweb in collaboration with Nielsen and Doxa, detected 9.2 million users online from smartphones and 4 million from tablets in Italy in August 2013 (this is data beta since Audiweb Mobile will officially start in January 2014).
Overall today 38 million Italians between 11 and 74 years of age declare that they can access the Internet from any tool and place thanks to network wireless: 35% more in a year from a smartphone (21 million Italians 11-74 years) and 160% more from tablets (6 million). On the other hand, fixed pc connections decreased: numerically by 3% compared to 2012 and by 7% in terms of online time for each user. The boom of the consumption of power related to wireless networks it has already begun in our hands.
According to the forecasts of the Center for Energy-Efficient Telecommunications Ceet in Melbourne, in 2015 90% ofpower consumed by an ICT infrastructure will be used by wireless networks, only 9% from the data center so far considered the main responsible for consumption of power. For consumption of course it also means the waste, that is the part of power which is lost in the form of heat.
In fact, the truth is that the total waste (non-consumption) of power of the networks Internet wireless used to access cloud services from network cell phones is up to 10 times higher than that of common data centers; this too is written in the Ceet study. In another document, this time by the American Barkeley Lab, it is stated that using applications directly online via a cloud infrastructure saves a lot of energy for a company. It would seem to understand that the cloud, by its very nature wireless, lower the consumption of power of the individual but the collective one increases. A theme to be explored.
