ARLB055 Pro-BPL comments lack technical substance, ARRL says
The ARRL said Broadband over Power Line (BPL) proponents have failed
to substantiate their claims that the technology will not cause
widespread interference. In reply comments filed August 20, the
League said that if the FCC is going to rely on industry statements
in making decisions on BPL deployment, the industry should back up
its assertions with technical studies and hard data and make these
public.
While BPL advocates claim no interference, ARRL said its own field
tests lead inescapably to the conclusion that BPL will, if deployed,
create widespread harmful interference. "The interference was
manifest and widespread and would be so even to an untrained
observer," ARRL said.
The ARRL supplemented its text comments with technical exhibits that
document the results of testing at several BPL field trial sites.
The League also noted that comments in the proceeding so far have
been silent on the interference susceptibility of BPL to ham radio
signal ingress.
"It is past time that the Commission acted in its proper role as a
steward of the radio spectrum and recognized the interference
potential of BPL to the sensitive incumbent licensed services in
these bands," the League concluded.
