The demand for fast Internet connections has increased dramatically in the past few years. As more and more people purchase home computers and set up home networks increasing, the need for spectrum internet wifi (high-speed) connectivity continuously rises. Two types of technology, cable modems and Asymmetric Digital Subscriber Lines (ADSL), are the two that today dominate the market.
Although both technologies allow Internet connectivity that is several times more efficient than a modem with 56K, more is needed to integrate home-based services like digital spectrum tv and video on demand.
However, another DSL technology known as very high bit-rate DSL (VDSL) is seen by many as the next step in providing a complete home communications/entertainment package. A few companies, including U.S. West (part of Qwest today), already offer VDSL services in specific regions. VDSL offers a fantastic amount of bandwidth, with speeds reaching 52 megabits (Mbps). Compare that to an average speed of between 8 and 10 Mbit/s for ADSL or cable modem, and the switch from broadband technology currently in use to VDSL might be nearly as significant as a switch of a modem with 56K broadband. As VDSL becomes more widespread, integrated packages will cost less than the total cost of the current services.
This article will help you learn the basics of VDSL technology, its reasons for being essential, and how it's different from other DSL technologies. First, let's look at the fundamentals of DSL.
A typical phone installation across the United States consists of a pair of copper wires the company installs at your residence. Copper wires have plenty of bandwidth to transmit data and voice calls. Voice communications use just one-third of the capacity of the wires. DSL utilizes the remaining capacity to transmit information over the wire without disrupting the line's ability to transmit conversations.
Standard phone service restricts the frequency range that phones, switches, and other devices can transmit. In normal conversational tones, human voices could be heard within a frequency range from 400 to 3400 Hertz (cycles every second). In most cases, the telephone wires can handle frequencies as high as thousands of Hertz. Modern equipment that transmits digital (rather than analog) data can utilize a lot more than the phone line capacity, and DSL can do that.
