Cable Modems

[gaf at blu.org (Jerry Feldman)]

Some cable companies did allow higher bandwidth. A friend of mine near rochester. NY on RR did 
have a full 10Mbps bandwidth on cable. There are several reasons that cable providers limit the 
bandwidth. One is to prevent single users from taking up all the available bandwidth. Another is 
for marketing where they can segment the market and provide higher bandwidths at a premium. 

On the upline side, the limit is usually with the cable plant itself. The repeaters themselves are 
very limited. 

Some of the former @home users have been complainig that AT&T has reduced their bandwidth 
since AT&T is limiting the bandwidth to 1.5Mbps.
