How does Cable High-speed compare to ADSL High-speed?
When the cable infrastructure is new and/or well maintained, the service is typically faster for downloads than most if not all ADSL lines however, cable has a few disadvantages to ADSL: – Cable internet is an RF network — this means that it is vulnerable to transient problems “within the network” from RF interference. Since cable is a shared media, there is a possibility that performance may degrade over time as additional households plug in, connect additional devices (videos, game machines) to the TV lines. – A cable company may react slowly to decreases in performance, as they never sell access by speed, or promise consistent speed or latency. – Cable companies are using a very narrow band for return signaling, below all the space allocated for TV channels. This band is prone to RF interference and is very limited in capacity. Upstream transmissions may therefore compete with others in the area, get delayed (suffer high latency) due to noise fighting techniques. – Cable Internet t
