3. Broadband over power lines (BPL) is a method
of that allows relatively
high-speed digital data transmission over the
public wiring.
With broadband over power lines, or BPL, you can
plug your computer into any electrical outlet in your home and
instantly have access to high-speed Internet. By combining the
technological principles of , ,
and , developers have created a way to send data over
power lines and into homes at speeds between 500 kilobits and
3 megabits per second (equivalent to DSL and cable).

5. How Broadband Over Powerlines Works
An emerging technology may be the newest heavy
hitter in the competitive world of broadband
Internet service. It offers high-speed access to
your home through the most unlikely path: a
common . (Broadband over
Power Line) technology makes possible high-
speed Internet access over ordinary residential
electrical lines. BPL offers an alternative
to or broadband Internet
services.

14. Broadband Over Power Lines
In summary, Broadband can be provided by:
• Wired connections: Telephone (POS), Cable (POS)
• Wireless: Satellite (WAN), WiFi (LAN)
• Optical Fiber (POS)
The Newest in Internet Service is
Broadband over Power Lines
(or “Access Broadband”)
with some unique features . . .

31. Broadband Over Power Lines
Wavelength λ = C / F, and C = 186,000 mi/sec
At 1 MHz λ ~ 1000ʹ, at 10 MHz λ ~ 100ʹ,
and at 100 MHz λ ~ 10ʹ
Less than about 3 λ is considered the Near
Field where unusual “echo” effects occur, and E
& M fields need to be measured separately, for
proper assessment.
3 λ at 10 MHz is ~ 300ʹ
32. Broadband Over Power Lines
BPL is covered under FCC Regulations, Part 15,
which implies that the information will not radiate,
However, the FCC overlooked some details . . .
36. DSL and cable modem Internet services bring high-speed
networking to the home and small business at an affordable
price. When comparing DSL vs cable, business and technical
advantages of both are apparent.
DSL and BPLSpeed - Bottom Line
Cable modem Internet services on average promise
higher levels of bandwidth than DSL Internet services, and
this bandwidth roughly translates to raw speed. However,
while cable Internet will theoretically run faster than DSL,
several technical and business reasons can reduce or even
eliminate this advantage.
37. DSL vs BPL Speed - Advantage Cable
In terms of theoretical peak performance, cable modem
runs faster than DSL. Cable technology supports
approximately 30 of bandwidth, whereas most forms of
DSL cannot reach 10 Mbps.
One type of DSL technology, can match cable's
performance, also supporting 30 Mbps. However, Internet
service providers generally do not offer VDSL, but rather the
cheaper and slower or services.

39. •Utilities can offer broadband service to every home with
their ubiquitous network.
•Broadband is the fastest growing telecom segment in
United States.
•Utilities see a promise of various utility applications on
the broadband, IP enabled network piggy riding on their
electric network.
40.
41. •BPL will be a niche Broadband Access technology – most
probably in the semi-urban towns.
•The technology is under close market scrutiny for its ability
to support a successful business model.
•Some utilities may delay their AMR decision with a hope of
using BPL one day.
•You need to keep our ear on the ground for meter
manufacturers planning to offer BPL enabled solutions.
