Citing successful co-existence of in-home BPL (HomePlug®) and amateur radio,
FCC official says that "amateurs can operate and BPL can operate in a
compatible mode" and comments specifically on BPL-generated RF interference
issues in Briarcliff Manor, New York, and Cottonwood, Arizona

Broadband over power line trials in Briarcliff Manor, New York, and
Cottonwood, Arizona, are under attack by amateur radio operators for
interfering with their FCC-licensed operations

Towards the end of 2004, Broadband over Power Line World reported on a spate
of complaints regarding broadband over power line (BPL) interference with
amateur radio operations in Briarcliff Manor, NY and Cottonwood, Arizona.

Since both of these BPL trials, as well as all licensed amateur radio
operators, are operating under regulations issued by the Federal
Communications Commission (FCC), Broadband over Power Line World contacted
and interviewed Bruce Franca, Deputy Chief of the Office of Engineering and
Technology at the FCC, in order to get the latest information regarding that
agency's attitudes towards, and involvement in, the deployment of BPL
technology, with particular reference to issues of BPL-generated RF
interference with amateur radio operations.



Amateur radio technology is NOT "antiquated and irrelevant," according to
the FCC

In that interview, recorded today, January 3, 2005, Mr. Franca says that it
is NOT the position of the FCC that amateur radio is an "antiquated and
irrelevant" technology and that "There are enough frequencies that amateurs
can operate and BPL can operate in a compatible mode." He also said,
speaking of BPL RF interference with amateur radio operations, "I'm very
optimistic at the end of the day. Technology is going to solve this problem.

Manor, New York

Speaking about complaints from the American Radio Relay League (ARRL), the
leading association of amateur radio operators, about the Ambient
Corporation and Con Ed BPL trial in Briarcliff Manor, New York, Mr. Franca
said that "at least with regard to Briarcliff we thought that there were
still conversations going on between the parties....We've suggested to
Ambient and Ambient has made several modifications to its system..We've had
some indication from some amateur parties that progress has been made..Right
before the holidays, we thought that the parties were at least making some
progress and that things were being worked out among the two parties."

As of December 18, 2004, however, ARRL was saying that the FCC had not acted
on its repeated requests to shut down this trial because they (ARRL) were
not satisfied with the interference mitigation efforts implemented to this
point by Ambient-Con Ed.

Cottonwood, Arizona

Regarding the BPL trial underway in Cottonwood, Arizona, which was being
conducted under the authority of an experimental radio license granted by
the FCC to Electric Broadband, LLC, a founding partner of which has said is
no longer involved in that trial, Mr. Franca said of whoever is conducting
the trial "they either have to operate under our rules [Part 15] or they
have to basically come in for a new authorization."


Cottonwood, Arizona, BPL trial is under new management

That is, in fact, what's happened. Mountain Telecommunications, Inc., which
has already told Broadband over Power Line World (BPLW) that it can't
discuss the Cottonwood BPL trial and attendant RF interference issues on
account of its contractual obligations with Arizona Public Service Company
(APS), which has told BPLW that its only involvement in the BPL trial in
Cottonwood is providing its lines, was today granted an "Experimental Radio
Station Construction Permit and License" by the FCC, call sign WD2XMB.

Except for the file number and the name and address in the upper left-hand
corner of the first page, this Permit-and-License seems to be identical to
the Permit-and-License to operate an experimental BPL trial in Cottonwood,
Arizona, issued previously to Electric Broadband. Pertinently, they both
include the same "Special Condition #11": "Licensee must establish and
maintain a liaison relationship with the Verde Valley Amateur Radio
Association."

Links to both Permit-and-Licenses, and related materials, can be found on
the appropriate FCC "Call Sign Report" page. That page reports that the new
license, specifying Mountain Telecommunications, Inc., as the permit holder
and licensee, was applied for by Electric Broadband.

Whether that is in fact true, or not, won't be known, if at all, prior to
comments on this question from the chief of the Experimental Licensing
Branch, who had already left for the day when the issuance of the new
license became known to Broadband over Power Line World.

The Verde Valley Amateur Radio Association, which is already on record as
dissatisfied with previous efforts to mitigate RF interference with its
members' amateur radio operations, will now, presumably, need to direct any
new complaints (and possibly re-send its previous ones) to the name and
address of the trial operator listed in the upper left-hand corner of the
new Permit-and-License, call sign WD2XMB.
