ADSL usage in other countries

rpm · Apr 7, 2004

Hi folks

This is just an interesting comparison about DSL usage around the world published in this week’s Time magazine.

“Broadband DSL penetration per 100 telephone lines:

US: 4.8 (cable is the most popular form of broadband connection here)
China: 5.1
Germany: 8.4
Finland: 11.8
Belgium: 15.4
South Korea: 27.7”

Any idea what the number for RSA is?

BTTB · Apr 7, 2004

It would be definitely less than 1%. Considering only about 16000 people the last I read had ADSL. What is 16000 of probably 10 Million phone lines?

Hi Dikbek

I am not completely certain about the numbers, but to the best of my knowledge SA has a minimum of 5 million phone lines (http://archive.salon.com/21st/feature/1998/11/cov_16feature2.html) and the number of ADSL users is around 16 000. This gives us a figure of 0.0032.

I would of thought more actually. Perhaps if telkom didnt cut off the marginal 2mil of the 2.5 mil customers due to fraud and unaffordability that Prof Melofy spoke about.

That would of made the 0.0032 figure even smaller.

So it's about 3 out of every thousand phones. Very small.[|)]

Those numbers can be very ... misleading. Here's additional data:

The U.S. has over 210 million telephone lines, among 290 million people. (72 telephones per 100 people)

China has 135 million telephone lines, among 1.3 billion people. (10 telephones per 100 people)

Germany has 51 million telephone lines, among 83 million people. (61 telephones per 100 people)

South Korea has 24 million telephone lines, among 48 million people. (50 telephones per 100 people)

South Africa has 5 million telephone lines, among 43 million people. (12 telephones per 100 people)

And you're right, cable is vastly more popular here. It is just a better technology. Fiber, cable, and then DSL.

You'd seriously need to seprate people living in rural areas of SA from people living in the first world areas.

Ie, the number of people living in JHB, vs the number of people with phone lines in the area.

Must face the fact that probably 60% to 70% of our population has no water or electricity let alone phone lines and cable internet.

Cable isn't actually better technology than DSL. It's much worse. Users share the same cable, on what is essentially an Ethernet bus, and the bandwidth goes potty the more users get connected to the same bus. Also, due to noise, and other equipment interference, pings are very unstable.

DSL is a much more precise, and guaranteed service than cable.

I have a thick juicy copper cable running in my neighborhood that is divided up into roughly two hundred 6 MHz slots. 125 is allocated to television. Of the rest, some is dedicated to uploading and some to downloading. Each 6 MHz channel is equal to 40 to 60 Mbps. My thick juicy copper cable carries over 1 Gbps in traffic. There is no distance restriction either.

DSL is very restricted to the frequencies it can use. In addition, it runs over a thin copper wire with very limited capacity. Third, if you have a fiber connection to your curb, you're in trouble because DSL doesn't work over fiber. Fourth, DSL has major distance issues that cable doesn't have.

Now the "shared service" myth. Did you know your DSL is shared after the first hop? Here, look:

DSL Person's modem connects to DSLAM. DSLAM connects to ISP. You have a shared line.

Cable Person's modem connects to ISP cable modem. You have a shared line.

Yes, my service is shared, but so is yours. If you are thinking your DSL isn't, well, don't let me bring you down to earth.

Now for the more users then the service goes "potty." DOCSIS 1.1 deals with that very well.

"Pings are unstable to do noise and other equipment interference..." Well, DSL requires you to put filters on your phone lines. Hmm. Everytime you pick up the phone you use the same line as your DSL line, just a different frequency. With cable, the channel is dedicated to only one thing: either internet, down internet, or up internet.

As for noise, well, lets see. I have a thick copper cable with thick plastic and aluminum insulation that is water proof. You have a telephone cable that is thin copper wires with a thin layer of insulation. Do you really want to know which one is more susceptable to noise?

Lastly, pings are unstable? Fascinating. How do you figure? Television is being streamed of the cable. That is literally VIDEO with SOUND. Want to know how many Mbps per second is that? Over 30. If the packets kept arriving out of sequence and was so unstable as you predicted, then one wouldn't be able to watch television. As a matter of fact, pings are MORE stable on cable than on DSL because of LESS noise and interference.

And to sign off, my personal experience. I have cable. Have had it for 5 years now. I've also had DSL while living in Waterloo when I go to school. That was a mistake. Cable was a better buy. Maybe it was a poor implementation, maybe not. You will get poor companies on both sides, so it greatly depends on how the company implemented his system.

However, all else being equal, you're far better of with a cable connection than with a DSL connection. That is why Japan, leader in broadband, offers 100/100 Mb cable that covers 90% of Japan, but only about 26 Mb DSL (with distance limitations).
