Internet-HDTV Wiring Requirements

Before the Internet revolution, buildings usually have two phone lines, electrical service and telephone service. When the computer network is necessary, the telephone lines are the only means for data transfer. The original network was created for computers to share information only piggyback on existing relationships and technologies.

Today, more accessible (and necessary) to meet the needs of consumers in the network. A good rule extends to the future ofcommunications: everything you can imagine for the future, and multiply that by ten. About twenty years ago could have foreseen the Internet or HDTV or mobile phones and iPods. And note that the growth of communications technology has proven to be exponential in the past, we have experience with a factor of ten for the next twenty years.

When you use the design and construction of a new structure, it is important to identify early in the process. When renewing aexisting facilities must be much the same considerations and the work is often more difficult.

Structured Wire

Structured wire is a technology of electricity interconnection, and is rapidly becoming standard in many parts of U.S. products are trying to anticipate future needs, and provides standardized methods for implementation. Structured Wire includes telephone, computer networks, video, fiber optics, and sometimes structures. Structured cablingWindows Services are usually about 4 'high with 4 large and installed in an area like the garage, attic or basement. Structured cabling is usually in a new facility, but can be used in existing structures.

Structured cabling services for groups of wires is structured a central panel, where services (cable TV, telephone, satellite, Internet, etc.) at home. It is a minimum requirement for each panel is a box for telephone connectioncessation pair, and a passive splitter cable for the coaxial cable. Rooms must be left panel updates.

Although each Ethernet and video cables can be specially designed multimedia cables are still standard. A double cable, for example, consists of an Ethernet network and a video link in a jacket. A second composite structure can include two Ethernet cables for voice and data cables and two videos. This wire-speed multimediaclearance times installation time, because more wires can be pulled at the same time, since all cut ends are identified.

Ideally, the wire network, configure a "home run, a separate connection for cable TV, telephone and Internet data transmission is made of structured cabling service panel at each point of use.

Structured Cabling Panels are used for miles of cable to provide the necessary Audio, TV, distribute surveillancevideo, telephone and digital communications applications, and now combined with multimedia services. structured cabling works well with a wireless network because administrators can connect the wireless access points throughout the house via an Ethernet connection.

Computer Networks

The technology choices are driven by the right kind of property that is served. A good plan communication link at all brought together at a central location. Can beEnter a phone line in series (room) to run, but not OK for cable Internet.

Technology is changing rapidly.

It 'was only 25 years ago that Steven Jobs said that no computer would ever need more than 64K of memory.

It 'important to ensure your future plans. Fiber Solutions today seems an unnecessary luxury, especially with the performance with a high-speed Ethernet network available. But the technology solutions for homes and smallBusiness applications are now based on Ethernet.

Wireless networking (WiFi) is another technology that is rapidly affecting computer networks. Research firm IDC predicts that the number of firms access points installed Wi-Fi will grow from 1.6 million units in 2006 to 11,500.000 units in 2010. Up to 20 users can connect to a single wireless access point and to receive appropriate service provider. IDC predicts that Ethernet switch ports, which are mainly used incompany grow from 172 million units to 208 million units during the same period.

Ethernet

Ethernet is the dominant standard for the network data is difficult to wire. Ethernet hardware is usually standard in all new computers. If the method of high-speed data (cable modem, DSL, etc.) Hard Wire interface for the computer normally have an Ethernet port.

Ethernet connections should not exceed 100 meters, and a separate cable is needed for information and phone numbers. ThisEthernet can be carried in a jacket almost like a phone, but can be unreliable, and certainly not recommended for high-speed Ethernet (> 100 Mbps). Use a separate cable, "design home run, where possible, a network switch for each point of use.

The new building, it is also advisable to connect the buildings with conduit. Install it on the ground while still cheap to make and maintain the property. Property will be future proof for laterupdates.

Strategies Links

There are two general methods for the renovation of buildings and wireless Ethernet. Wireless has the advantage that it is cheaper and easier to implement, especially for changes. It is not always the case. The answer today is probably a combination of both systems. On-site self-evident and static, for example, home office, an Ethernet connection is appropriate. Cover the system with a wireless network (WiFi)The network will provide improved flexibility.

Wireless

Wireless Ethernet (802.11) can be a good choice for change communication for small projects. WiFi works on radio frequency (RF) and is designed for wireless digital communication between PCs and consumer electronics. Most new computers include integrated WiFi support. Wireless Ethernet applications, including large buildings. wireless access in public areas of a building as a swimming poolarea, an elegant solution. Wireless is also an excellent choice where it is difficult to run additional wires.

Hard Wire

In some cases, rewiring it makes more sense. For larger projects is a hard line approach more reliable and ultimately, cheaper. Wireless looks good on paper but in a large building, universal connectivity, is difficult. The average cost for ReWire with Ethernet cable is about $ 300 to the point of use in large buildings. During the infrastructure in placefuture expansion to justify the cost of rewiring.

Environmental issues should be considered when rewiring. Issues such as asbestos and the reduction of lead paint are examples. There are programs that rewiring is not an option because of building restrictions, except without the channel, and the beauty of this solution is often hindered. Once the cables are installed, network performance is easy with standard Ethernet hub or switch equipment. Remember that a100 meters distance limitation of Ethernet. In large projects. Finding Ethernet switches in each building or each floor of a skyscraper for a solution to the problem

Fiber Optic Ethernet

The fibers are probably not the right place to put today's data communication capacity high-speed Ethernet to handle short distances typical of large buildings. But it is difficult to predict the future. Fiber optic cables used in place of traditional copper cables, because this techniqueprovide additional capacity and are less susceptible to electrical interference. Optical fiber is becoming more common as a way high-speed Internet service (100 Mbps and higher) to be delivered.

Uncompressed HDTV

If you want to distribute compressed video, said the proceeds of a satellite receiver or cable, the bandwidth requirements are large. The alternative would be to distribute the compressed signal and install a receiver (with relief) in any point of use.If you are in the first field, read on, otherwise you can forward to the next section.

Today's video installations have become more complex, with source components positioned for a good distance from the screen. The distance is the main determinant of which technology to use. There are two possibilities, copper or fiber.

An uncompressed digital video signal is a challenge. Optical fiber that connects the best technique for DVI and HDMI, because of theavailable bandwidth. The bandwidth of Ethernet is less than 0.6 Gbps, which is much lower than uncompressed video data (1.65 Gbps), it is easy to understand why fiber optic is better when it comes to digital signal transfer high bandwidth for long cable runs. Typically, the 1080p signal would mean 1920 x 1080 pixels at 60 Hz for this high speed and high data bandwidth, impedance of copper cables many, signal loss less than 20 feet, and leads toconsiderable confusion.

Reliable connections over time should also be considered. The optical conversion electronics must be at least 80,000 hours of continuous operation. Fiber optic cables are immune to electrical noise interference Gadio frequency (RFI). With Fibre conversion, there is zero impedance (zero transmission losses).

Summary

The high quality of interconnection is an investment. While digital video technology to improveYou can upgrade your DVD player or TV, and it is important to ensure that you connect damaged. A technique used for good, at least 1080p. Fiber optics can be expensive, but the price difference is to be considered for future proofing the system now.

The goal is to create a cost-effective, future-proof deployment. It is more expensive and difficult to retrofit later. Cheap computers, internet and digital communicationstransformation of the planet. Twenty years after mad rapid progress in computer technology have made businesses and households in ways that will not recently.
