From the ARRL web page:
FCC Releases Broadband Report (Nov 5, 2007) — The FCC has released their latest report summarizing the state of broadband in the US as of December 2006. It shows that in December 2006, Internet-access BPL has increased slightly over December 2005, but also shows that it has been decreasing slightly from a peak that occurred sometime around mid-2006. According to the report, BPL ended up with a deployment total of 0.006 percent of the total broadband lines in the US, compared to 0.011 percent at the end of December 2005.
OK, let’s just see how BPL is doing in terms of adoption. Here are the number of BPL subscribers listed in the report:
June 2005: 4872
December 2005: 4571
June 2006: 5208
December 2006: 4776
So in the last six months of the study, BPL actually declined in use while the other broadband technologies increased by 17 million. See Slow Death for Broadband Over Powerline.
