New numbers from Nielsen show how mobile broadband is increasingly playing a role in our lives. Via Phil Goldstein of FierceWireless:

In the first quarter of 2012 the average U.S. mobile subscriber used 450 MB of data per month, according to research firm Nielsen. That figure is more than double the average of 208 MB per month for all U.S. mobile subscribers in the first quarter of 2011.

While this is definitely good news — mobile broadband is a driving force in closing the digital divide — it also highlights the critical importance of freeing up more airwaves for wireless use.
