Hams Encouraged by NEW Motorola BPL Technology
Newington, Conn., May 23, 2005
--ARRL, the national association for Amateur Radio, announced today that "The
ARRL is pleased to hear Motorola's announcement of its Powerline LV system.
This is the first Access Broadband over Power Line (BPL) system that has been
designed from the start with radio interference concerns in mind."
Motorola's Powerline LV system avoids
using the medium-voltage (MV) power lines and introduces broadband signals only
on the low-voltage (LV) side of the power transformer. This greatly reduces the
potential for interference to and from radio users, especially radio amateurs.
ARRL Chief Executive Officer David Sumner commented, "We
know that medium-voltage (MV) power lines are no place for broadband energy,
since there is overwhelming technical evidence that radio interference from BPL
is unavoidable if MV lines are used. By confining their Access BPL system to LV
lines and by adding hardware notch filters for additional protection to amateur
radio frequency allocations, Motorola has addressed our interference
concerns."
While sometimes pictured by BPL proponents
as opposing all BPL implementation, the ARRL has always maintained that radio
amateur "hams" are not interested in blocking new technology but are
justifiably concerned about pollution of the radio spectrum. Significant
interference has been documented at numerous sites where other BPL systems are
being tested, and other BPL developers have been unwilling to share information
about their systems. By contrast, Motorola invited ARRL's suggestions and
welcomed its input during product development.
Sumner concluded, "We look forward to seeing the
first Powerline LV system in operation, and to continuing to work with Motorola
to ensure that their new product is indeed the first BPL system that is a
solution, not a problem."
There are approximately 670,000 Amateur
Radio operators in the United States. Many other countries are watching events
unfold in the US as they plan their own BPL systems. There are
approximately 2.5 million Amateur Radio operators around the world. If the new
Motorola system lives up to its initial promise in actual deployment, this
new "shortwave-friendly" system will have many advocates.
