1000 kb/s (i.e. 1 Mb/s) nel 2018 per un'abitazione, con tutto il video di cui si parla nello studio, non è un po' pochino? Oppure sulla scala delle ordinate c'è un errore (kb/s invece di Mb/s)?
Roberto, a parte il fatto che la scala e' logaritmica, i numeri indicati sono quello che noi chiameremmo la "banda minima garantita"...
It can be seen that in 2008 the busy-hour bandwidth requirement per household in the UK is around 24kbit/s (of which about 20% originates from video services). Under Scenario 1 this was forecast to grow at a compound annual growth rate (CAGR) of 29% to reach around 300kbit/s per household by 2018. Under Scenarios 2 and 3 the bandwidth requirement grows to around 950kbit/s per household in 2018 and in Scenario 4 to about 2000kbit/s per household.
For comparison with historical trends, in 2001 ISPs typically provisioned 5-6kbit/s per user for busy-hour bandwidth. The growth rate between 2001 and 2008 was therefore 23% per annum. It seems reasonable to expect a higher rate of growth in the future given the increasing availability and user awareness of video services.
