Iím not going to go too technical here.. But cable will always be better than ADSL (Internet through your telephone).
Itís one thing that really annoys me when ADSL companies (Like BT, Sky, Talktalk) advertise 20mb broadband, when you donít actually get anything near that.. yet you still pay for it..
For example, you pay for 20mb.. then depending on how far you live away from the exchange, that could then be halved.. to 10mb.. but ADSL also has a contention ratio (for sky its 50:1).. so with a 50:1 contention ratio, youíre fighting 50 people to get that 10mb.. which means you usually end up with like 4-5mb.. Yet your still getting charged for 20mb..
With Cable, you have Fibre Optic cable to the green box at the end of your road, then copper cable to your door, which means the loss of strength is minimal! But the key thing is youíre on a 1:1 contention ratio.. which means youíre not fighting anyone for your internet! I have 20mb Internet, and usually get about 19-21mb some evenings (Yes I can download as sometimes over 2mb a second some nights!).
So for me, cable (Virgin in this case) is simply the way forward, not just for value for money, but if youíre into the techie side, they also have a better Upload
speed than ADSL companies too.
OFCOM should really intervene with ADSL companies to make sure you only pay for the maximum internet speed you can get!
