"Source" Disavows Inflated NTIA BPL Figure

The National Telecommunications and Information Administration (NTIA
<http://www.ntia.doc.gov/> ) report Networked Nation: Broadband in America
2007
<http://www.ntia.doc.gov/reports/2008/NetworkedNationBroadbandinAmerica2007.
pdf>  that was released on January 31, 2008 includes the following: 

	Reliable BPL [broadband over power lines] subscribership figures are
difficult to find. The FCC's most recent data identify fewer than 5,000 BPL
customers as of yearend 2006. That figure appears low, however. TIA [The
Telecommunications Industry Association] estimates 200,000 current BPL
subscribers. 

Five years of experience in dealing with BPL systems as a radio interference
source have given the ARRL, the national association for Amateur Radio,
considerable insight into the BPL industry. Based on that experience, the
ARRL has concluded that the FCC's figure of fewer than 5000 BPL customers is
entirely credible. Therefore, the ARRL set out to determine the source of
the "estimate" of 200,000 current BPL subscribers. 

We contacted TIA <http://www.tiaonline.org/>  and were advised that the
figure came from a market study prepared by Wilkofsky Gruen Associates Inc
<http://www.wilkofskygruen.com/>  and based on research conducted by In-Stat
<http://www.instat.com/> , a unit of Reed Business Information. 

So we contacted In-Stat and asked how the figure was derived. They
responded: "The 200,000 number for BPL subs did not come from In-Stat. In
our US broadband forecast, we estimate about 231,000 broadband subscribers
in the 'other' category besides DSL, cable, satellite. Other includes BPL,
but is not solely BPL." 

We then contacted Wilkofsky Gruen Associates. They responded: "Our source
for the BPL figures was In-Stat." When In-Stat's denial was shared with
them, they responded, "It was our understanding that BPL was the principal
component as it was the first item listed by In-Stat." 

TIA was invited to comment but declined to do so. 

In other words, here is what we have learned: In-Stat does not claim to know
how many BPL subscribers there are, but provides an estimate of 231,000
broadband subscribers who receive service via delivery systems other than
DSL, cable, and satellite. Wilkofsky Gruen Associates, on the basis of
nothing more than that BPL is listed first, assumes that the bulk of these
231,000 are BPL subscribers and arbitrarily attributes 200,000 of them to
BPL. In turn, NTIA -- not satisfied with an FCC figure that is derived from
required reports from service providers -- cites this arbitrarily chosen
figure -- a figure that is entirely unsupported by any data whatsoever -- as
evidence that the FCC's figure -- which is fully supported by data --
"appears low." 

On February 1 we called upon the NTIA to issue a corrected report
<http://www.arrl.org/news/stories/2008/02/01/101/?nc=1> . We renew that call
now.
