This is an ISP provider.This will access to Internet in Very High Speed that Dail up modems.Most of areas are provided with 21.1 mb speed of broadband.
Networks that use cable modems on standard cable television infrastructure are called broadband to indicate the wide range of frequencies that can include multiple data users as well as traditional television channels on the same cable. Broadband systems usually use a different radio frequency modulated by the data signal for each band.
The total bandwidth of the medium is larger than the bandwidth of any channel.The 10BROAD36 broadband variant of Ethernet was standardized by 1985, but was not commercially sucessful.The DOCSIS standard became available to consumers in the late 1990s, to provide Internet access to cable television residential customers. Matters were further confused by the fact that the 10PASS-TS standard for Ethernet ratified in 2008 used DSL technology, and both cable and DSL modems often have Ethernet connectors on them.Power lines have also been used for various types of data communication. Although some systems for remote control are based on narrowband signaling, modern high-speed systems use broadband signaling to achieve very high data rates. One example is the ITU-T G.hn standard, which provides a way to create a high-speed (up to 1 Gigabit/s) Local area network using existing home wiring (including power lines, but also phone lines and coaxial cables).
Broadband are also given from Fiber connection,cable connection etc...Fiber connection will give super fast high speed internet upto 1 GB limit or more.Because the the fiber is also known as Optical Fiber because the electrical signals are produced by a optical laser,thats why its called optical fiber..
This all i know about broadband...Please give some comments..about some article.if this are article is not correct to you im very sorry,You can also give some ideas by posting to my blog..
