View Full Version : ADSL2 - speed vs distance

So Telecom has upgraded a lot of exchanges to ADSL2. I understand this increases traffic speeds. Does ADSL2 reach further than ADSL along the old copper cables?

Some rural users are too far from the exchange to get broadband. Will ADSL2 help?

I heard that if you're more than 2Ks from the exchange, you'll hardly feel any difference between ADSL and ADSL2+.

my router shows that I'm getting around 3500 Kbps downstream when lucky
and downstream Line Attenuation is 47.1 dB right now
is it possible to use these stats to determine my distance from exchange so I can also refer to the graph too?

the internet plan I am on is suppose to give me unlimited download speed and 128 upload

No.
Theres more to it than just the distance.

There is a formula that crops up here and there on the web that says
line length(km) =attenuation divided by 13.8.

Also a chart here-
www.internode.on.net/adsl2/graph/index.htm
that may be worth a look for a ballpark figure.

Not "unlimited", just as fast as the line will allow - big difference.

My router tells me I'm on ADSL2 now, I think i've been upgraded - but haven't noticed any difference in speed. (except that connection speed is now the same as 'attainable line rate' - but download speed is exactly the same)

Mind you, I wasn't getting maximum for ADSL anyway, so it's not surprising.

I've used those formula before
but didn't come to a solid conclusion

I'm guessing since I'm only getting 3.5Mb/s speeds, I'm not going to benefit too much from ADSL2, since my line's not that great
and by unlimited, I'm just saying that my ISP shouldn't be a limiting factor

.

That makes mine .217


Its not just distance. I'm close, but speed is rubbish.

That calculates my distance rather accurately, but according to the graph, I should be getting just over 3500kbps... Yet I am very lucky to get 1600 kbps...

Here (http://www.speedtest.net/result/236974737.png) is a speedtest to a Wellington server (I am not far from wellington) and look at that... :groan: Then there is Napier (http://www.speedtest.net/result/236975152.png) and Auckland (http://www.speedtest.net/result/236975372.png)...

Time to change isp?

Time to change isp? Probably, though I have more important things that take priority and really can't be bothered changing at this time... LOL :groan:

Working... aint it great at times... :yuck:

The attenuation reported by the modem includes internal house wiring.
Ask a neighbour what they are getting, in fact, ask as many as you can and if you are all getting the same speed, then you would be better changing houses than ISPs.

I'm around 3.5km away from the exchange. Bit sad that we won't enjoy adsl2+ for some years. Get a max of around 2.4mbps. It's ok.
