Broadband is a high-speed Internet connection that provides a large bandwidth. It is considered a very quick connection. It is an "always-on" type of connection and can transmit data at a much faster rate than your usual dialup connection. Broadband also has the added advantage of not tying up your phone line, which means you can use the both the Internet and telephone at the same time. Broadband can be provided from a variety of sources, including over the top of your phone line as in ADSL or on dedicated line such as Cable or ISDN.
Typically, low-band Internet access is running up to 56kbps using a dial-up modem. Mid-band Internet is described as dialup access that operates at 64kbps or 128kbps. Standard broadband starts at 512kbps, which is about five times faster than dial-up service. Broadband is also available at 1mbps, 1.5mbps and 2.2mbps. There are companies that offer broadband at 4mbps and 8mbps. The maximum possible for cable is around 26mbps and 24mbps for ADSL. These speeds are not sold commercially because the cost to upgrade the telephone lines to be able to transmit data at these speeds is very high.
Downloading and streaming music and video is very quick with broadband. There are a lot of websites now that are designed especially for broadband users. They have intense integrated graphics, flash and video. Broadband is also popular for online gaming. Game consoles like Xbox and PS2 have broadband support included. You can then subscribe to different types of gaming packages from your current ISP, which makes it possible to play Xbox and PS2 games live with other gamers over the Internet. Actually, online PC gaming has been going on since the Internet came into use, but in the past it was difficult to do. Slow and jerky response from your computer made it hard to play, and you always had to keep an eye on the time. Now, with the faster speeds of broadband, it has become much easier and is quickly gaining in popularity. Some games are now being released that require an Internet connection to play.
The growing popularity of broadband has made it necessary for most providers to put a maximum limit on the amount of music, video and other data you can download. This limit can vary greatly, from as low as 1 GB up to 30 GB. Extreme users can get unlimited downloads if they wish. However, exceeding your ISP's download limit usually results in having a limited connection or no connection at all.
One of the possible futures of broadband is Internet Television. The current bandwidth, which is the amount of data you can send and receive, is not wide enough to provide an image that is of comparable quality to that of your standard television. The ever- increasing broadband speeds will make Internet Television a reality. Since you can currently download clips from the shows, music videos and other content you like, it will soon be possible to do it legally in real time. Another use of broadband is online telephony. This is software that allows you to use your computer as a telephone and talk to people from anywhere without any extra cost. It is becoming commonplace, and has a higher quality or recording than a traditional telephone line. With the increase in the speeds of broadband, it may soon replace your television and telephone, and will find its way into every home. The success of broadband is making the Internet a great resource that's easy to use and fun to access for a variety of needs.
What is broadband high speed Internet? First, let us find the basis for comparison for in-home broadband services, often called consumer class, which is basic dial-up. Dial-up access streams at 56 Kbps (Kilobits per second), and it requires the use of a phone line. One cannot surf and talk at the same time. The cost for dial-up is $10-$25 per month. Reading further, one finds that with broadband high speed Internet, there is no comparison to dial-up Internet.
Satellite broadband has a 400 Kbps speed downstream and upstream speed. A satellite connection can be used when DSL and Cable are not available. Unlike dial-up, satellite is an instant connection; multiple PC's can share the connection, and there is no need for a second phone line. Home satellite broadband high speed connections run approximately $60-100/month.
In comparison, DSL has a speed of 128Kbps to 1.5 Mbps downstream speed. 64 Kbps to 1.5 Mbps upstream speed which is up to 50 times faster than dial up, but one still has to have a landline for DSL. Downloading and streaming music, videos, movies, and playing online gaming just became faster and easier. Home-based DSL costs about $40-$50 per month.
Cable modems have 200Kbps to 2 Mbps downstream & upstream speed. Cable modems are always on with instant access, and there is no hassle with having a second phone line. Cable modems have comparable cost to DSL.
Units of Measurement - Broadband Internet Access Speed
bit= smallest unit of digital information, i.e. ones & zeros byte= a set of bits bps= bits per second Kbps= kilobits per second =1000 bits per second Mbps = Million bits per second =1,000,000 bits per second Gbps = Gigabits per second = 1,000,000,000 (one billion) bits per second Tbps = Terabits per second = 1,000,000,000,000 (one trillion) bits per second
Consumer class broadband differs in costs and services offered from high speed Internet for businesses. For instance, DSL for business runs at 128Kbps to 1.5 Mbps downstream, and 64Kbps to 1.5 Mbps upstream for a cost of $90-$400 per month, depending upon the bandwith speed required.
Another variation of business broad band is Fractional T1. Provided at the speed of 128 Kbps to 1.0 Mbps, Fractional T1 speed has some of the 24-64 Kbps channels turned off. Prices are approximately $220-$500 per month depending on fractional bandwidth speed required, which includes local loop. Hardware and installation costs vary.
DSL and Fractional T1 can be combined for a broadband speed of 1.544 Mbps using a digital circuit. T1/DS1 is dedicated Internet access, point-to-point or integrated (voice & data). Prices are approximately $500-1000 per month which includes local loop. Hardware and installation costs vary.
Fractional T3, which is 3 Mbps to 44.736 Mbps basic T3 with some of the 67-264 Kbps channels turned off, comes at a hefty price of approximately $3000-$5000/month, depending on fractional bandwidth speed required.
T3/DS3 has a broadband speed of 44.736 Mbps digital circuit. It can be dedicated Internet access, point-to-point or integrated. Prices are approx. $5000-15,000 per month plus local loop. Set up costs will be additional.
