Prior to the Internet revolution, buildings commonly had two wiring systems, the electrical aid and the phone service. When computer networks were required, phone lines were the only means available for data transmission. The traditional networks that were created for computers to share data plainly piggybacked over existing connections and technology.
Today, more options are available (and needed) to meet the networking needs of consumers. A good rule when projecting the time to come of communications: whatever you can imagine for the future, and multiply that by ten. Who twenty years ago could have anticipated the Internet or Hdtv or cell phones or Ipods. And given that technology increase in communications has proven to be exponential in the past, we need to multiply that sense by a factor of ten for the next twenty years.

Structured Wire
Structured wire is a technology of electrical interconnect, and is rapidly becoming approved in many parts of the U.S. The products try to anticipate time to come needs, and furnish standardized methods for implementation. A Structured Wire installation includes telephone, computer networking, video, and sometimes fiber optic facilities. Structured Wiring aid Panels are commonly about 4' high by 4' wide and are installed in a aid area such as a garage, attic, or basement. The Structured Wiring is most often installed in new construction, but it can be utilized in existing structures.
The Structured Wiring aid Panels for a structured wire installation is a central panel where services (cable Tv, telephone, satellite, internet, etc.) enter the house. A minimum requirement for each panel is a telephone-connecting block for terminating the twisted pair, and a passive cable splitter for the coax. Room should be left in the panel for upgrades.
Although personel Ethernet and video cables can be used, specifically designed multimedia cables are becoming standard. A dual cable, for example, consists of one Ethernet and one video interconnect under a singular jacket. Someone else composite construction could consist of 2 Ethernet cables for voice and data and 2 video cables. These multimedia cables speed the installation time because complicated cables can be pulled at the same time, and it minimizes termination times since all ends are identifiable.
Ideally, the wired network has a "home run" configuration: a detach interconnect for cable Tv, phone, and Internet data transmission is made from the Structured Wiring aid Panel to every point of use.
Structured Wiring panels are used to furnish the miles of cable interconnects required to distribute Audio, television, security camera video, telephone, and digital communication applications, and now combines it with multimedia facilities. Structured wiring works well with a wireless network because administrators can associate wireless passage points throughout the house straight through an Ethernet connection.
Computer Networks
The right technology option is driven by what kind of asset is being serviced. In a good communications interconnect plan, all interconnects are run to a central location. It may be Ok to run a phone line in series (room to room), but it is not Ok for Internet network cables.
Technology changes fast.
- It was only twenty-five years ago that Steven Jobs said that no computer would ever need more than 64K of memory.
It is prominent to future-proof your plans. Fiber-optic solutions seem to be an unnecessary luxury today, especially with the carrying out available with high speed Ethernet. However, the majority of technology solutions for residential and small company applications are currently based on Ethernet.
Wireless networking (WiFi) is Someone else technology that is rapidly impacting computer networking. Shop study firm Idc projects that the total amount of company WiFi passage points installed will grow from 1.6 million units in 2006 to 11.5 million units by 2010. Up to 20 users can associate to a singular Wlan passage point and receive adequate service. Idc also predicts that Ethernet switch ports, those predominantly deployed in enterprises, will grow from 172 million units to 208 million units in the same period.
Ethernet
Ethernet is the dominant approved for hardwire data networking. Ethernet hardware is commonly approved in all new computers. If the recipe for high-speed data (cable modem, Dsl, etc.) is hardwire, then the interface to the computer will commonly be an Ethernet port.
Ethernet interconnections should not exceed 100 meters, and detach cables are needed for data and phone. It is possible to run Ethernet in the same jacket as phone, but it can be unreliable, and is surely not advisable for High Speed Ethernet (> 100 Mbps). Use a detach cable, the "home-run" design, where possible from the network switch to each point of use.
With new construction, it is also advisable to interconnect buildings with conduit. Setup it in the ground while it's still cheap to do so, and, keep the proprietary rights. This will future-proof the asset for later upgrades.
Retrofit Strategies
There are two base methods for retrofitting buildings: Wireless and Ethernet. Wireless has the apparent advantage of being less costly and easier to implement, especially for retrofits. However, this is not all the time the case. Today, the rejoinder is probably a composition of both systems. At points of use that are obvious and static, for example the home office, an Ethernet relationship is appropriate. Overlaying this system with a wireless (WiFi) network provides improved flexibility.
Wireless
Wireless Ethernet (802.11) can be a good option for communication retrofits for small projects. WiFi operates on radio frequencies (Rf) and was industrialized for wireless digital communication between personal computers and buyer electronic devices. Most new computers consist of built-in WiFi support. Wireless Ethernet has applications including large buildings. Wireless passage within base areas of a property, such as a pool area, can be an elegant solution. Wireless also is an perfect option where it is difficult to run supplementary wire.
Hardwire
In some situations, rewiring can make more sense. For larger projects, a hard wire coming is more reliable, and in the end, cheaper. Wireless looks good "on paper", but in a large building, universal connectivity is difficult. The median cost to rewire with Ethernet cable is about 0 per point of use in large buildings. Having infrastructure in place for time to come expansion may elucidate the price of rewiring.
Environmental issues must be determined when rewiring. Issues such as asbestos and lead-paint abatement are examples. There are those applications where rewiring is not an option because of construction constraints, unless covering conduit is used, and esthetics often preclude this option. Once the wiring is installed, implementing the network is uncomplicated using approved Ethernet hub or switch equipment. Remember that there is a 100 meter distance limitation with Ethernet. In large projects, locating Ethernet switches in each construction or on each floor of a high rise resolves the issue.
Fiber Optic vs. Ethernet
Fiber is probably not the solution to deploy today given Ethernet's quality to cope high speed communication over the short distances typical of large buildings. But it is difficult to anticipate the future. Fiber optic cables are used instead of traditional copper cables because this technique offers more capacity and is less susceptible to electrical interference. Fiber optic is becoming more base as a way to furnish very high speed Internet aid (100 Mbps and higher).
Uncompressed Hdtv
If you want to distribute uncompressed video, say from the yield of a satellite or cable receiver, then the bandwidth requirements are significant. The alternative would be to distribute the compressed signal, and Setup a receiver (with decompression) at each point of use. If you are in the first camp, read on, otherwise you can skip send to the next section.
Today's video installations grow ever more complex, with source components positioned a good distance away from the display. The distance is the biggest factor in determining which technology to use. There are two choices, Copper or Fiber Optic.
An uncompressed digital video signal is a challenge. Fiber optic interconnect is the best technique for Dvi and Hdmi, because of the titanic bandwidth available. The bandwidth of Ethernet is less than 0.6 Gbps, and this is much lower than uncompressed video data (1.65 Gbps), it is easy to understand why fiber optic is best when it comes to high bandwidth digital signal exchange for long cable runs. Typically, 1080p signal would mean 1920 x 1080 pixels at 60 Hz. At this high rate of speed and large bandwidth of data, the impedance of many copper cables can cause signal loss at less than 20 feet, and this results in vital distortion.
Interconnect reliability over time should also be considered. The optic conversion electronics should last at least 80,000 hrs of continuous operation. Fiber optic cables are immune to electrical interference such as gadio frequency interference (Rfi). With Fiber Optic Conversion technology, there is zero impedance (zero loss during transmission).
Summary
High quality interconnect is an investment. As digital video technology improves, you may be upgrading your Dvd player or Tv and it is prominent to make sure your interconnects do not come to be obsolete. Use a technology good to at least 1080p. Fiber Optics may be more expensive, but the price differential may be worth observation for future-proofing your system now.
The goal is to deliver a cost-effective, future-proof deployment. It is more costly and difficult to retrofit later. Cheap computing, the Internet, and digital communications are transforming the our planet. Twenty years of stunningly rapid advances in technology have brought computing into businesses and homes in ways that were recently not imagined.
