Last year’s VNI report, which projected surging demand on wireless networks, was an input into the spectrum demand analysis we released this past fall.

The bottom line is that Cisco continues to foresee an enormous surge in wireless demand. Let’s take a look at their North American regional breakout. Cisco estimates that in 2010, North Americans transmitted 49 Petabytes (PB)per month over mobile networks. That’s about 4,900 times the amount of information in the printed collection of the Library of Congress. By 2015, Cisco expects this number will grow to 986 Petabytes – nearly one Exabyte, equivalent to almost 100,000 Libraries of Congress.
