Electrical outlets found on virtually every wall of every home in
America are poised to revolutionize home networking. Power-line
networking, which allows data to ride on electrical wiring at speeds up
to 14 Mbps, appeared to be killed off by cheap

wireless networking solutions in early 2002. But a new crop of
standardized, low-cost power-line routers and Ethernet and USB adapters
are poised to create a highly effective networking environment for homes
and businesses by complementing existing 802.11, or
Wi-Fi
(define -

According to research firm
InStat
MDR
(news

home networking entered the mainstream in 2003 and in early 2004, as
droves of broadband users installed home networks to share Internet
connections. InStat MDR estimates that the continued need for broadband
sharing and an exploding interest in entertainment networking will drive
the total value of equipment with a home networking connection of some
type from $8.3 billion in 2004 to $17.1 billion by 2008. Likewise, the
majority of enterprise

(define -

alert) budgets is going toward local and wide-area networking to
accommodate highly distributed workforces that require access to
centralized corporate information.
Most users are turning to wireless networking based on some flavor of
802.11 for their computer networking needs. According to Jupiter
Research, the percentage of U.S households using 802.11 is expected to
reach 8% in 2004, twice the percentage in 2003. The biggest advantage of
802.11 is its simplicity. One can connect computers anywhere in the home
or office without the need for wires. The computers connect to the
network using radio signals that provide coverage of 150 feet in every
direction.
Yet 802.11 networking technology alone is not the perfect solution.
While many 802.11 signals can travel farther than 150 feet, the radio
waves tend to degrade when they attempt to travel through the walls of a
home or office. Users have to move the 802.11 adapter around until they
receive a better signal to the gateway, if possible at all. Often signal
speeds can be as slow as 2 Mbps and are subject to intermittent signal
dropouts. A recent Wall Street Journal article
highlighted users’ frustration over various Wi-Fi dead spots. It seems
those who cut the computer wires expect to access the Internet, share
printers, files and gaming sessions in their bedrooms, attics, basements
and garages.
Power-line networking, based on
HomePlug PowerLine Specification 1.0.1
(news

networks. HomePlug hardware easily extends the reach of 802.11 networks
to the outer areas of the office or home. All users must do is plug
power-line adapters into their nearest electrical outlets to form a
network over their home electrical wiring. The network is entirely
self-discovering and self-configuring with transmission rates of up to
14 Mbps that incorporate powerful 56-bit
DES
(define -

additional software installations.
Older product versions of power-line networking technology were
expensive, slow and non-standardized, resulting in the belief that Wi-Fi
networks would trump the need for power-line networking forever. Today,
power-line networking devices cost less than $100 and are offered by
some 14 different manufacturers. The beauty of such products is their
true plug-and-play nature and their ability to operate using any
electrical outlet, regardless of how old the electrical wiring is
without degrading the existing power supply.
Many analysts agree that the home network of the future will not
encompass a single technology solution. The growth of broadband services
is exploding as computer users are quickly growing accustomed to the
integration of the Internet into every aspect of their lives. Homes with
multiple personal computers, Internet devices and smart appliances
require ubiquitous connection to the web. Using power-line networking
technology as the home local area network backbone, roaming from one
WLAN

is a reality.
A Jupiter Research study
concluded that no single standard or network type will dominate the
industry, despite the hype surrounding 802.11 networking. “Rather,
consumers will make their choice based on a variety of factors,
including convenience, price and ease of installation.”
A recent white paper from Parks Associates and Global Inventures
indicates that “wireless and wired backbone hybrid networking solutions
will be one situation where different connectivity solutions work in
concert to deliver greater flexibility and value to the end user.”
Power-line networking technology is ushering in a new type of home
networking: entertainment networking. Imagine a home theater that feeds
audio to its speakers via power lines, making speaker wires unnecessary,
a security camera that is immediately connected to a computer simply by
plugging in the device or a television that automatically connects to
the cable box, the DVD player, the digital video recorder the home
theater system and even the Internet once it’s connected to an
electrical outlet. That is the reality of the HomePlug AV standard,
which is being developed by the HomePlug Powerline Alliance to enable
audio and video streams to be sent over power line. This technology will
be built in to a wide variety of consumer electronics enable the
distribution of data and multi-stream entertainment throughout the home,
including high definition television and standard definition television,
