In general, broadband refers to telecommunication in which a wide band of frequencies is available to transmit information. Because a wide band of frequencies is available, information can be multiplexed and sent on many different frequencies or channels within the band concurrently, allowing more information to be transmitted in a given amount of time (much as more lanes on a highway allow more cars to travel on it at the same time). Related terms are wideband (a synonym), baseband (a one-channel band), and narrowband (sometimes meaning just wide enough to carry voice, or simply "not broadband," and sometimes meaning specifically between 50 cps and 64 Kpbs).
Various definers of broadband have assigned a minimum data rate to the term. Here are a few:
Newton's Telecom Dictionary: "...greater than a voice grade line of 3 KHz...some say [it should be at least] 20 KHz." Jupiter Communications: at least 256 Kbps. IBM Dictionary of Computing: A broadband channel is "6 MHz wide."
I recently read about a company called Nethercomm that is promoting a broadband in gas technology.
Apparently, this company has some patents pending on devices that can be installed in gas pipelines
that go to commercial and residential buildings to provide the "last mile" connection for broadband.
It appears the technology is based on radio frequencies propogated down the gas pipe as a wave
guide. Nethercomm boasts data rates up to 40 Mbps are possible to the home. Anyone know of any
actual implementation/trials of this technology going on presently?...

here is an interesting take by an internet geek, on why he's giving up broadband (for good?).
http://news.bbc.co.uk/2/hi/uk_news/magazine/4242751.stm too bad i can't relate much since i
still use dial-up up to this point. /tongue.gif' border='0' style='vertical-align:middle'

getting online consumes a lot of my time, and sometimes, it takes over my life leaving me with tons
of things left undone. and that is with a dial-up, how much more when i get broadband? i coul...
