Today’s illusive
home of the future is suddenly coming into sharper focus as new
home wiring systems set entirely new standards of convenience by
enabling devices to be connected tone another, as well as to the
world outside.
The term connected
home describes a collection of equipment linked throughout the
house. These devices can include anything from televisions, VCRs,
computers, close - circuit cameras, modems, and printers to
household appliances of every sort. With a fully connected home
the boundaries between community, work, family and entertainment
choices simply begin to disappear. The home becomes much more
accessible.
In a customer’s
connected home, they can have multiple PCs in different parts of
the house communication, exchanging files or playing the latest 3
– dimensional computer games. They can program a movie to play on
all of their home’s television sets. Music can be enjoyed
throughout the home, and they can monitor their baby’s nap on any
television or computer screen in the house. A connected home can
even answer the doorbell for them.
Your customers can
manage their home’s basic functions such as security, energy
management, and lighting, directly or through remote access.
Check or set their home’s alarm system or monitor fire and
intruder detection from the office. Set there heating and cooling
systems to be active when they’re home and inactive when they’re
asleep or away. Spot heat or cool certain parts of their house.
Adjust lighting for ambiance, activates, or for varying needs
throughout the day. A home outfitted with an adaptable, high-tech
infrastructure will enjoy growing value.
The connected home’s
true potential is based on the power of high-speed data
communications. Although products are available that allow
limited connections through existing phone jacks, electrical
wiring, or wireless, these schemes lack the ability to fully
utilize today’s powerful and sophisticated multimedia
communications. Today’s voice, data and video applications
require faster and more voluminous data rates than the traditional
home – wiring infrastructure can handle.
Making your customer’s home connected is a matter of installing a
network similar to the one they probably have in their office, but
much simpler. A new generation of residential wiring has been
developed for this purpose, which is known as structured wiring.
Structured wiring – which can be readily installed into new
construction – allows homeowners to integrate the control and
operation of telephones, VCRs, cable television, home – office
equipment, security systems and environmental management systems. |

The structured
wiring that will enable their connected home is similar in concept
to the wire that already delivers television programming to their
living room or telephone service to their kitchen. However, this
new generation of wire is of higher quality, and is installed
following a few fundamental concepts:
- The wire is no
longer daisy – chained from one information outlet to the next,
but is “ home run “ from each information outlet back to the
central connection point. The home run architecture allows for
better signal integrity and convenience when adds or changes are
needed.
- New information
outlets are added by home running a new wire from the service
center to the information outlet, and not by cutting and
splicing into an existing wire.
- Trained and
qualified installers should install structured wiring systems.
Just like a garden hose loses water flow when kinked or pulled
too tight around a bend, so will a data cable lose speed if not
properly handled and installed.
The wire runs
throughout the house, connecting the various rooms, and terminates
in a central location – the service center. The service center is
a metal box that can be either surface – or flush – mounted in a
closet or a utility room. It is the central interconnection point
for all signals passing through the system and provides a central
distribution point for voice, data and video services. All cables
run directly from the service center to information outlets in
rooms throughout the home.
These information
outlets connect different endpoints in the house to the service
center.
These outlets –
which various devices are plugged into – can be mounted alone, or
together with an AC wall receptacle. They provide a single access
point to connect telephones, televisions, VCRs and computer
equipment to the structured wiring system. Each outlet is
designed to support one or more different types of devices: one,
for example, connects telephone and computer networks, another
accommodates internal and external video sources, such as closed –
circuit cameras or cable television. They choose which devices
they want in each room.
Today, homes are designed and built with multiple outlets in every
room. Electricity at every point in the home has become an
essential requirement for homeowners. The same model holds for
digital services. Information outlets in the connected home will
become as ubiquitous as AC outlets. |

More Consumers See
Technology As A Requirement, Not An Option
So what is
structured wiring and why can it make such a difference in a
consumer’s decision to purchase a new home? Structured wiring is a
combination of wiring types that work in conjunction to deliver
data throughout a home. This includes telephone, video and
computer network wiring such as category – 5, RG – 6 coaxial and
possibly fiber optic cables. All terminate at a central location
within the house, generally referred to as a wiring can.
Essentially structured wiring is the backbone for communications
and entertainment in the home.
Why is this becoming
something that people want or feel they need in a new home? Simple
– the emergence of the Internet as an important part of a family’s
life. With growing numbers of families having more than one PC,
and everyone wanting to get online at the same time, the need for
a built – in networking system is becoming more apparent. Parents
are increasingly bringing work home, or becoming telecommuters,
and many grade – school students are using the Internet as a
reference tool. By including a structured wiring system that
includes the ability for Internet sharing, it is possible for
every family member to access the web simultaneously.
With the rapid
growth of the Internet, many service providers are looking to
capitalize on a high-speed connection into the home as a means of
providing more services to customers. Telephone companies are
beginning to roll out digital subscriber line (DSL) service in
many areas that deliver a high-speed Internet connection over
existing telephone lines in addition to phone service. Cable
television companies are starting to offer Internet service
through high-speed cable modems in addition to their existing
video services. While theses, in and of themselves, are not
driving the growth of structured wiring, in order for a customer
to take full advantage of the service they need an in – home
networking infrastructure.
The Future
Looking down the
road a few years, many of these service providers are planning to
broaden their offerings even more. Soon residents will have the
option of receiving all of their in – home services from a single
provider, via a single connection in the home. These services,
known collectively as “broadband” services require a simple device
called a residential gateway. This gateway coordinates the
incoming signals and sends them to the right system using a
structured wiring network in order to deliver those services
throughout the home.
With all of these
developments happening it is no wonder that consumers are asking
to have structured wiring built into their new homes. By
incorporating theses capabilities into a home they are able to
take advantage of the advances it offers today including
PC –
to – PC networking, video distribution and device sharing and
flexible location for phone lines. Understanding the capabilities
that a structured wiring system offers today, and the additional
benefits that is offers for tomorrow is critical when deciding the
right solution to meet homeowners evolving needs. |
