As the FCC itself has made abundantly clear, the definition of "broadband" is an ever-changing one, and its latest report has now revealed just how hard it is for the US to keep up with those changes. According to the report, a full 68 percent of "broadband" connections in the US can't really be considered broadband, as they fall below the agency's most recent minimum requirement of 4 Mbps downstream and 1 Mbps upstream. Also notable, but somewhat buried in the report, are the FCC's findings on mobile broadband use. The agency found that mobile wireless service subscribers with mobile devices and "data plans for full internet access" grew a hefty 48% to 52 million in the second half of 2009, and that when you consider all connections over 200 kbps, mobile wireless is actually the leading technology at 39.4 percent, ahead of cable modems and ADSL at 32.4 and 23.3 percent, respectively. When it comes to connections over 3 Mbps, however, cable modems account for a huge 70 percent share. Looking for even more numbers? Hit up the link below for the complete report.
