Major U.S. Technology Milestone: COMTek, City of Manassas Deliver First City-Wide Availability of Broadband Over Powerline (BPL) In The U.S.

The 37,000-person Washington, D.C.
suburb of Manassas, Virginia, is now home to a major national success story in
broadband access: the first city-wide commercial deployment of broadband-
over-powerline (BPL) technology anywhere in the United States, according to
Communication Technologies, Inc. (COMTek), the Chantilly, Va.-based "Inc. 500"
company that owns and operates the BPL network in Manassas. BPL technology
uses the electricity grid in a city and the wiring in individual homes to
provide direct "plug in" broadband access through electricity sockets, rather
than over phone or cable TV lines.
COMTek said that the roughly 12,500 households in Manassas now are within
the reach of its BPL network and that commercial services are available
throughout the city to 2,500 businesses on an on-demand basis. COMTek already
has an estimated 700 customers in Manassas, with another 500 requests for
service now being processed. In addition to Manassas, COMTek is in
negotiations to deliver similar services for nine other investor-owned
utilities, municipal-owned utilities, and other entities.
COMTek Founder and CEO Joseph E. Fergus said: "This is truly a historic
day for COMTek, which is the U.S. leader in broadband over powerline services.
The major national technology milestone that we are announcing today with the
City of Manassas is the most eloquent possible expression of our commitment to
grow the BPL category of broadband access. Make no mistake about it: What
we are announcing today in Manassas is something that we could be rolling out
in a year or two from now in literally scores of communities across the U.S.
The Manassas experiment is a good thing for every American who lives in any
city or town with little or no access to affordable broadband."
City of Manassas Mayor Douglas Waldron said: "Manassas resolved to move
forward with broadband over powerline as a major enhancement of what our city-
owned utility provides to its customers. COMTek accepted the challenge of
working with us by building a BPL network that would serve all of our
citizens. This has proven to be an extraordinarily positive and results-
oriented partnership in which every citizen of Manassas can take pride. We
have accomplished something here that will be a model for other cities and
towns across the United States."
Congressman Frank Wolf (R-VA) said: "Congress is looking closely at ways
to improve broadband access in rural and other non-urban settings and that is
why I am so encouraged by the Manassas success with broadband over powerline.
The City of Manassas and COMTek are to be applauded for their leadership roles
in pioneering access in a way that has never been achieved anywhere else in
the United States. Now, the challenge before us is to make this same sort of
success story blossom across the nation."
American Public Power Association President and CEO Mr. Alan H. Richardson
said: "The American Public Power Association's member-supported Demonstration
of Energy-Efficient Developments (DEED) program provided a grant in 2001 to
the City of Manassas for the initial investigation of how BPL could provide
Internet access to consumers and businesses, while enhancing the efficiency
and reliability of the electric utility. The City of Manassas has led the way
for many other community-owned electric utilities. Its successful deployment
and 'lessons learned' will help other public power communities evaluate the
communications and utility opportunities of this technology."
In July 2004, the City of Manassas selected COMTek to provide BPL services
over the city's electric system. COMTek owns and operates the BPL network and
also serves as the ISP, providing email and Web hosting services for
customers. COMTek signs up and services the needs of Manassas customers. The
City of Manassas provides utility staff to install BPL couplers and repeaters
and to maintain the fiber connections that link COMTek servers and routers to
the power lines. The city receives a portion of subscriber revenues to offset
the manpower and equipment resources that they contribute to the BPL services.
In addition to delivering broadband access to residential and commercial
customers, COMTek has enabled the Manassas utility to save money and respond
more quickly in identifying outages at both the transformer and customer
level, central control for traffic signals, and operating video surveillance
systems at substations. The City is exploring opportunities to use BPL for
other advanced utility applications such as automatic distribution switching,
which would restore power more quickly to the grid after outages, and
automated meter reading, which already is available on the Manassas network.
In February 2005, COMTek was identified as a national leader in broadband-
over-powerline technology by a report from the New Millennium Research Council
(NMRC). The report noted that trials and actual commercial deployments of BPL
systems are on the rise, with over 20 projects in operation in 2004 and more
expected to come online in 2005. Roughly a quarter million homes in the
United States already had the opportunity to choose BPL services in 2004,
according to NMRC.
Major investments in BPL technology have been announced in recent months
by such major entities as Google, Hearst and Goldman Sachs. Both the White
House and Federal Communications Commission (FCC) have highlighted BPL
technology as an important way to get broadband access to underserved portions
of the nation.

HOW BPL WORKS
Broadband over power line is the transmission of high-speed communications
services, including Internet access, over the existing electric infrastructure
using adaptive technologies. The wires that carry electricity, either on poles
above ground or through underground pipes, possess the capacity to also serve
as a conduit for data signals. These power lines are known as medium voltage,
carrying between 1,000 and 32,000 volts of electricity and travel the
distances between power substations and the customer's household or building.
The electric lines that connect to a household or other building from the
utility pole are known as low voltage, transmitting 120/240/480 volts.
By bundling radio-frequency (RF) energy on the same line with the electric
current that is already carried, data can be transmitted without the need for
a separate line. Since the electric current, which is used to provide power to
the end users, and RF energy signals carrying the data operate at different
frequencies (with electric current traveling at lower frequencies and data at
higher levels), the two don't interfere with each other.
Technological advances in the past several years have enabled electric
companies to place devices along existing wires and poles to provide broadband
services. Known as Access BPL, the systems require a connection from the
Internet backbone at a power substation, repeaters (in some cases) and
couplers along the medium voltage power lines that transmit the data signals,
and then a final converter that transfers the signal from the medium voltage
to the low voltage lines that go into homes. Once inside the home, the signal
can be accessed at any electrical outlet with a BPL modem.
