Cable Modem versus DSL

By Dennis_Baluh ·
I am trying to find a good source of reference for the debate on high speed Internet service, cable modem versus DSL. I am looking for pros and cons, to make an education and cost effective solution.

Area dependant

by Oz_Media In reply to Cable Modem versus DSL

Cab;e is are a dependant, you may get screaming speeds from 9-5 but after 8 it slows down a little due to the network congestion on the lines.

ADSL depends on which service you get from your telco or DSL provider.

eg. In North Vancouver, Telus offers unlimited bandwidth at 1.5/Mbps for only $40.00/mo. BUT it is via DHCP server login.

Telus offers Business class DSL for $80-$150/mo depending on the speed available or required 1.5Mbps - 5 Mbps. via static IP addressing.
In the latter, DSL is MUCH faster but also more expensive. Also the Business class service is based on Static IP Addressing.

So, there are MANY variables as to what is best for you, the modem is rather important but you ususally just get what your given, the service in your area is by FAR the important part to look into though.

Good luck,

Varies by ISP

by TheChas In reply to Cable Modem versus DSL

The effective speed varies by the ISP and how they are set up.
Further, how you use the connection impacts the effective speed.

Cable 'typically' has faster maximum download speeds. But, your actual speed will vary depending primarily on how many other users are on the same trunk-line from the cable company.

DSL on the other hand, usually has faster up-link speeds. If you send a lot of files or data, SDSL would be the way to go.

DSL performance also suffers as you get further away from the phone switch that services your area.

With cable, your choice of ISP is usually limited to the cable company that serves your area.

With DSL, you may be able to choose from a number of ISPs if you do not like the service or support from the phone company that operates the line to your house.

From the security view, DSL wins hands down.

First, you are not on a 'shared' line.
There is no way for your neighbor to tap into your DSL signal and monitor your surfing habits.
(without making a physical connection to your phone line)

Second, many cable ISPs provide you with a static IP address. Whereas, DSL is usually a dynamic IP address.
With a static IP address you are an easier target for hackers and spys.

It varies where you are

by TomSal In reply to Varies by ISP

The easy answer is the simple truth -- it varies depending on where you are in the country/ who your provider is.

As far as the security issue is concerned DSL is more secure, but unless you are a criminal or working on HIGHLY HIGHLY sensitive data - why be overly paranoid about a security issue especially since both are PUBLIC access methods? Neither offer government grade security or are private networks.

Both are susceptible to attack, DSL is more harder to attack with the regard that you are not sharing the connection. But its still possible.

I look at speed.

DSL is often the winner with Upload bandwidth, Cable with download.

Recently Comcast cable in my area has offered 256k upload which on average is equal to most DSL connections, at the same time I average about 2-3 mbps of download speed (that's about equal to 2x T1 speed).

In theory the more online in a cable service the more bandwidth is shared -- in reality sometimes the provider manages the amount of users per trunk very well so there is very little problem with bandwidth being sucked up by volume of users. Personally, I've had cable modem service for almost 3 years now with Comcast and I honestly only remember about three times that I was cursing at my computer (go figure I'm impatient) about it being slow to download.

Its almost ALWAYS at *least* T1 speed (easiest way to describe it).

Chas !

Security of Static vs Dynamic adderssing is dependant on ISP.

I use a Business Class ADSL service with Static IP addressing. It is imperative for the VPN networking I do. I use a Rrouter with Port Address translation as well as Netware's own DHCP. I will agree that as a home user Static is more secure BUT you often get much slower connections from a residential ISP with DHCP such as the Telco. they just run out of addresses and it will take longer to assign your address from DHCP when you try to login.

So.... In a nutshell, for business I'd always recommend a static Ip addressing with PAT on the router. For residential, it all pretty mush sucks and has major downfalls but DHCP is still slower on a whole.

Mistake noted

by Oz_Media In reply to Chas !

I said that "I will agree that as a home user Static is more secure..."

I meant DHCP.

But that should be done server side, not at your ISP.

But all in all, no matter what service you use;
>>>>>>>>>>>>>>>>>>TELCO'S SUCK!!!!!!<<<<<<<<<<<<<<

Find a private ISP.
