How Broad is Broadband?
Photon01 writes "The Register reports that UK ISP NTL have lost, in a ruling that their advertisement of their 128k broadband service as 'High Speed Broadband Internet' is misleading.
This is despite it clearly meeting the technical definitions of broadband internet.
Apparently 128k broadband is not broad enough." My first cable modem was only 256k. It wasn't blazingly fast but after being stuck on dialup it was heaven, and I imagine 128k wouldn't be so bad for a single household.
well, it's all realative. back in the mid 90's, dual channel ISDN was amazingly fast, and is what everyone wanted for their businesses. now a days, we know that ISDN isn't all that hot, and then the ADSL are to be considered lower end broadband. so how broad is broadband? well for me, right now, it's about 800k/sec sustained download from sunsite. kinda hot.
This is what comes of marketting departments taking a technical term and redefining it. The opposite of broadband is not narrowband, but baseband (eg the defunct V.35).
What can be done to stop sales and marketting (and politicians) from diluting perfectly good technical terms.
how many brands can a broadbrand brand if a broadband could broad brands?
When you buy gasoline, the octane rating is Required by law to be posted. A similar system of 'Broadband Octane', so to speak, would allow consumers to more effectively make decisions on internet access.
In addition, there seems to be a growing trend of 'broadband' carriers who are slowly jacking down the bandwidth to each individual, either by packing in more consumers on a main line, or forcing the hardware to lower rates. In any case, more unsolicited disclosure would be welcomed.
I got ADSL myself, at 376kbs down and 128kbs up. It's not very broad for a broadband (indeed, some argue that ADSL can't be defined as broadband), but I picked it for quite another reason then bandwidth; I'm always on. And when you're used to pay for the minute, that's pretty darn important - I've saving about 50% each month compared to a dial-up connection. I would say that for my use, thats more important than the speed with wich I can D/L over P2P.
Everything in the world is controlled by a small, evil group to which, unfortunately, no one you know belongs.

Units of Measurement
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
(Network speed is mesured in 1000 units, memory and storage space in 1024 units)
I'd say the problem was that it was marketed as high speed broadband. While 128Kbps may technically be broadband, I don't think many people would consider it to be particularly high speed.
They were advertising "high speed" broadband internet access. It may well be broadband, but it certainly isn't "high speed" broadband.
"Low speed broadband" would have been more appropriate, but of course, they would've made their offering pale in comparison with real "high speed" broadband, so greed took over and caused them to advertise in a misleading fashion.

From WordNet (r) 1.7
broadband
adj 1: of or relating to or being a communications network in which
the bandwidth can be divided and shared by multiple
simultaneous signals (as for voice or data or video)
2: responding to or operating at a wide band of frequencies; "a
broadband antenna" [syn: wideband]
From The Free On-line Dictionary of Computing (09 FEB 02)
broadband
A transmission medium capable of supporting a
wide range of frequencies, typically from audio up to video
frequencies. It can carry multiple signals by dividing the
total capacity of the medium into multiple, independent
bandwidth channels, where each channel operates only on a
specific range of frequencies.
See also baseband.

It's not how much you have have, it's how you use it.
Broadband means it's a communications channel divided into multiple chunks. Each person on a cablemodem connection uses a different freqency range on the same cable, that makes the cable broadband. The opposite of broadband is baseband, that's where the base comes from in 100BaseT.
If you divide a 2400 baud modem among several users in that way, it can be called broadband too even though each user only have a few hundred bps.

It's not clear how this term became associated with DSL. Early on, DSL was referred to as "data over voice". (This came from the old "data under voice" system, which sent very low data rate signals for alarms and such over lines also carrying voice, using a frequency band somewhere below 100Hz.) Both of those terms are now obsolete.
DSL has no DC component (you can put it through a capacitor and it works just fine) so technically, it is "broadband". But that has nothing to do with the data rate.
From a regulatory standpoint, what we need is this: It is deceptive advertising to advertise an "up to" speed without showing, with equal or greater prominence, a guaranteed minimum speed. This rule should apply generally to any advertising that specifies some numeric measure of goodness.
