HOW DOES
ADSL COMPARE TO CABLE MODEMS?
ADSL provides a dedicated service over a single telephone line; cable
modems offer a dedicated service over a shared media. While cable
modems have greater downstream bandwidth capabilities (up to 30 Mbps),
that bandwidth is shared among all users on a line, and will therefore
vary, perhaps dramatically, as more users in a neighbourhood get online
at the same time.
Cable modem upstream traffic will in many cases be slower than ADSL,
either because the particular cable modem is inherently slower, or
because of rate reductions caused by contention for upstream bandwidth
slots.
