Broadband upload speed

[ProfPete]

I demand 10

[matt2056]

Just been talking to one of the Network guys and they are saying that we might re-segment the downstream carriers freq. As you prob work out that if they re-segment it it would give us more to play with.. The problem we have with upstream speed is we use (i think there called QTA cards) on the UBR's. At a grand a piece they be a bit expensive... Down here in Glos and Chelt we have 50 of them. Because the upstream is at 20mhz - 29mhz it gets effected by the noise so they won't really consider going to QAM64 or above at that freq cux of the problems we would get. And the money to do it. We would have to treble our work force just to try and keep the noise down. Fun Hey... There are talks thou of moving the upstream channels to above 100mhz or above but it would mean replacing all the QTA cards. Again MONEY........ Anymore info I get I will post or if you got any direct Q'a pirvate message me.

matt question for ya m8ee
i want to run a radio station for my p2p prog users. on my 4mb how many users cud actually listen in without it seriously effecting my speeds?

Depends on the bit rate you use, 384kbps upstream will provide enough for 3 users at 96kbps, 4 users at 64kbps, while still leaving you a little bandwidth for downloading purposes.

by using sam broadcaster at 24kb will have enough for 10 or more then as it states on mp3pro sound is still good qual?

You could shove more than 10 down it, but that's a nice safe limit so that your downloads won't suffer

@ Question for matt

Hi mate, when is the next upgrade to occur for all speeds, and by how much? May is it?

[ameen]

i have a 2mb download speed broadband cable but my upload only go upto 30kB/s is that how it supposed to be

[jazpearson]

i've just changed to telewest, and am very unimpressed by the upload speed. with adsl i was on 1024/256, but switching to cable, i'm on 1024/128. i really should have checked it out, but i didn't think to.

Is it likely that Telewest are going to upgrade anything? and in particular the upload speeds?

[jtwn]

You can, get 2mb. 384k with the 4mb too.

[MalcUK2005]

Telewest have said before that the reason why they don't do upload speeds is because their running a comercial service and comercial customers should't be running servers or uploading lots of files.

Do you mean residential instead of commercial? You supply a commercial service to business custs

[MalcUK2005]

Yeah sorry I meant non-comercial (ie Residential)

A question then that I read somewhere else but no-one ansered!

NTLââ‚Âà ‚¬ÃƒÂ¢Ã¢â‚¬Å¾Ã‚¢s new tiers consistently offer a 10:1 ratio between downstream and upstream havenââ‚ƚ¬Ã¢â€žÂ¢t NTL moved over to 3.2Mb and MC28 cards meaning that each upstream can be 8 X 3.2Mb = almost 26Mb.As docsis downstreams are only 27Mb why cant NTL offer a more symmetrical service?

LOL I love it when people look up a few buzzwords and try to make out they have a clue.

Firstly MC28 cards offer 2 downstreams and 8 upstreams, that would suggest 4 upstreams per downstream, wouldn't it?

Secondly 3.2Mb? Erm, no, moved to 3.2MHz wide upstreams, which offer after overheads about 4.4Mbps a piece.

Third DOCSIS downstreams aren't only 27Mbps they can be 27 or 38.

Fourth, MC28 cards actually reduce the upstream bandwidth available per downstream most of the time - they are there where areas are using lots of downstream compared to upstream, and have certainly not replaced the MC16 cards.

Finally can't offer a more symettrical service because in some areas even with 10:1 ratio on downstream to upstream upstreams get maxed well before the downstream. Due to statistical contention 4x4.4Mbit doesn't go nearly as far as 1x17.6.
