Broadband in general refers to data transmission where multiple pieces
of data are sent simultaneously to increase the effective rate of transmission.
In network engineering this term is used for methods where two or more signals
share a medium.
Various forms of Digital Subscriber Line service are broadband in the sense
that digital information is sent over one channel and voice over another channel
sharing a single pair of wires. Analogue modems operating at speeds greater than
600 bit/s are technically broadband. They obtain higher effective transmission
rates by using multiple channels with the rate on each channel limited to 600
baud. For example, a 2400 bit/s modem uses four 600 baud channels (see baud).
This is in contrast to a baseband transmission where one type of signal uses a
medium's full bandwidth such as 100BASE-T Ethernet.
Communications may utilise a number of distinct physical
channels simultaneously; this is multiplexing for multiple
access. Such channels may be distinguished by being separated
from each other in time (time division multiplexing or TDMA), in
carrier frequency (frequency division multiplexing (FDMA) or
wavelength division multiplexing (WDM)), or in access method
(code division multiplexing or CDMA). Each channel that takes
part in such a multiplexing exercise is by definition narrowband
(because it is not utilising the whole bandwidth of the medium),
whereas the whole set of channels taken together and utilised
for the same communication could be described as broadband.

Confusing usage
While many lower rate forms of data transmission, such as
analogue modems above 600 bit/s, are broadband, broadband has
been more closely associated with higher data rate forms of
broadband data transmission such as T-carrier and Digital
Subscriber Lines. Therefore, the word "broadband" has also come
to mean a relatively high rate, while the term "narrowband" is
used to mean a relatively low rate. It is now quite common to
hear a broadband method such as a 9600 bit/s modem described as
"narrowband", while a high rate baseband transmission such as
10BASE-T is described as "broadband". The International
Telecommunication Union Standardization Sector (ITU-T)
recommendation I.113 has defined broadband as a transmission
capacity that is faster than primary rate ISDN, at 1.5 to 2 Mbit/s.
However speeds of 256 kbit/s and greater are commonly marketed
as "broadband" and this convention is held to by policy makers
and ISPs alike. See Broadband Internet access. Note: The term
"narrowband" is also used to mean the opposite of "wideband"
instead of the opposite of "broadband".
Asymmetric Digital Subscriber Line (ADSL Broadband) is a form of DSL,
a data communications technology that enables faster data transmission over
copper telephone lines than a conventional modem can provide.
ADSL Broadband has the distinguishing characteristic that the data can flow
faster in one direction than the other, i.e., asymmetrically. Providers usually
market ADSL Broadband as a service for people to connect to the Internet in a
relatively passive mode: able to use the higher speed direction for the
"download" from the Internet but not needing to run servers that would require
bandwidth in the other direction.
There are both technical and marketing reasons why ADSL Broadband is in many
places the most common type offered to home users. On the technical side, there
is likely to be more crosstalk from other circuits at the DSLAM end (where the
wires from many local loops are close together) than at the customer premises.
Thus the upload signal is weakest at the noisiest part of the local loop, while
the download signal is strongest at the noisiest part of the local loop. It
therefore makes technical sense to have the DSLAM transmit at a higher bit rate
than does the modem on the customer end. Since the typical home user in fact
does prefer a higher download speed, the telcos chose to make a virtue out of
necessity, hence ADSL Broadband.
For conventional ADSL Broadband, downstream rates start at 256 kbit/s and
typically reach 8 Mbit/s within 1.5 km (5000 ft) of the DSLAM equipped central
office or remote terminal. Upstream rates start at 64 kbit/s and typically reach
256 kbit/s but can go as high as 1024 kbit/s. The name ADSL Broadband Lite is
sometimes used for the slower versions.
Note that distances are only approximations. Signal attenuation and Signal to
Noise Ratio are defining characteristics, and can vary completely independently
of distance (e.g., non-copper cabling, cable diameter). Real world performance
is also dependent to the line impedance, which can change dynamically either
dependent on weather conditions (very common for old overhead lines) or on the
number and quality of joints or junctions in a particular cable length.
A newer variant called ADSL2 provides higher downstream rates of up to 12
Mbit/s for spans of less than 2.5 km (8000 ft). Higher symbol rates and more
advanced noise shaping are responsible for these increased speeds. ADSL2+, also
referred to as ITU G.992.5, boosts these rates to up to 25 Mbit/s for spans of
less than 1.5 km (5000 feet). ADSL2+ also offers seamless bonding options,
allowing lines with higher attenuation or lower signal to noise (SNR) ratios to
be bonded together to achieve theoretically the sum total of the number of lines
(i.e., up to 50Mbit/s for two lines, etc.), as well as options in power
management and seamless rate adaptation - changing the data rate used without
requiring to resynchronise.
Because of the relatively low data-rate (compared to optical backbone
networks) ATM is an appropriate technology for multiplexing time-critical data
such as digital voice with less time-critical data such as web traffic; ATM runs
widely over ADSL technology to ensure that this remains a possibility.
ADSL Broadband service providers may offer either static or dynamic IP
addressing. Static addressing is preferable for people who may wish to connect
to their office via a virtual private network, for some Internet gaming, and for
those wishing to use ADSL Broadband to host a Web server.
