what makes Cable connection so much faster than DSL?

Question

Cable-7.5Mbps
DSL1.5Mbps
-both with 94% quality of service, DSL was actually like 96%

Answer 1

Essentially you are looking at a difference in "last mile" delivery methods. Cable is delivered over coaxial cable while telephone service is delivered on the much cheaper telephone grade wire. As the coaxial cable can pass a much higher range of frequencies for a much greater distance, it is inherently faster. In both technologies, the internet must use the available bandwidth not used by the original use of the wire. In telephone service you strip off about 5000 hz for voice service leaving the rest for data. In cable delivery you strip off a hundred and more tv channels leaving the rest for data. Imagine the types of speeds that cable could deliver if it were not for those pesky tv channels.
The real advantage with dsl is the ability to sustain the maximum capabilities of the line indefinately while cable as a shared medium fluctuates with your neigbors useage. Cable deals with this by providing a higher bandwidth to work with. Cable companies will increase the bandwidth available to subscribers as the competition increases their bandwidth. Right now they do not have to as their product is much faster than anything else available.

Answer 2

Well, DSL is not limited to 1.5. However...the overall available bandwidth that comes from coaxial cable versus a twisted pair comes from noise suppression. The coaxial cable is able to suprress the noise much better allowing for more overall total bandwidth.

However, as the telephone companies get rid of the regulatory issues that block their network expansion, they will be able to start delivering their next generation product. This will be VDSL, capabale or delivering 52mbps. This will allow them to deliver tv signals over the phone line.

Answer 3

Cable provides all his customers with 4Mbps but DSL less than that because you pay much less for DSL if you call them and tell them you will pay ten dollars more you get faster connection, I am payin $75.00 a month for cable. I used to pay $29.95 for DSL.

Answer 4

It has to do with the infrastructure used to distribute the signal.

Cable comes to your door by fibre, then a bit of coax. DSL uses the 50 year old twisted copper pairs in the street (usually). The bandwidth capable to be carried by cable is an even bigger difference than you have noted....

Answer 5

Cable companies upgrade their networks for two-way data transmission capabilities and with fiber-optic lines. Because data sent through fiber-optic lines is transmitted at the speed of light transmission speeds are much faster than those along other conventional copper wire technologies. Monthly charges for cable are also slightly lower and offer package deals for cable TV subscribers.

Answer 6

may b u r getting a slower speed dsl service.in theory , dsl is faster than cable.once when many people get on the net with cable in the neighborhood, ur speed will get slower.since dsl use one particular line for each it shouldn't hav such a problem on rush hour jam on the net although it might get slower not because of dsl but from the server.

Answer 7

Nothing, they both come in different speeds. The faster it is, the more you pay for it. DSL speed is based on distance where as cable is based on how many people in your area have cable

Answer 8

Great point, but I'm not 100%

Answer 9

It depends..
