Vodacom launches HSUPA

Could some one run some tests, I am quite excited about this.

For those in the know, I have a Linksys HSDPA router with a Mobile connect PCMCIA card, will Vodacom release anything that would work with this device.

Thx
 
Now all we need is for the price to drop a little bit...
 
I guess MTN will now announce that they will offer HSUPA as of today (on some tower somewhere) just to beat Vodacom...

Sorry for my misunderstanding but an increased uplink wont effect latency, unless HSUPA uses some other form of modulation to decrease latency on the radio interface? Sure you will be able to upload more information at a greater speed but still that doesn’t effect latency hopefully I am wrong O_o
 
i can see some peeps on here going

I cant get close to 3.6 why they offering HSUPA...e.t.c
How can they offer this if i cant get 3g in my area ..e.t.c

lets not go there be positive,atleast someone is thinking about SPEED BUT data is still dam expensive.

Exactly what I was thinking as well.

AFAIK higher upload speeds won't improve latency at all...they are different concepts.

Unless they meant higher upload speeds AND lower latency which is not how I read it :/

lol or that they did last week, and they wont tell you which tower and nobody would be able to find this tower that has been supporting it for a week already...
 
People have also said that the 4mb ADSL upgrade to 640kb upload could result in lower latency, but I can't understand it either.

Could RPM or anyone else explain how this works? (Unless your upload was previously being fully utilised of course)
 
Sounds like my crappy Vodacom connection is about to become crappier....
 
Even when the mobile operators fully flesh out their own fibre networks and we get oodles of international bandwidth - you still wont be able to get proper speeds on HS*PA or 3g. pointless in my view (though i do use it for some things). cable FTW.

A data packet consists of a certain number of bits. This packet is clocked out one device (say a data card) into the next device (say the base station) at the speed in bits/second of the underlying medium.

So a packet of a known size will take a specific time to be clocked across the link. Increase the link speed and the time to clock it across the link (link latency) will decrease by the proportional amount.

So, higher speeds equate lower latency ON THAT LINK.

The total network you see is made of a number of these links and their individual latencies add up to give the round-trip latency.

So, upping the speed, on one link (UPA, in this case) will improve the round-trip latency, but by what measure is a factor of the number of links in the path and how much delay each contributes.
 
Hehe...here's my weird analogy:

Think of data packets as trucks delivering goods.

when you request/send data (the trucks get an order) the latency (time taken for truck to reach it's destination) will not be affected. just because it can upload MORE (Bigger containers) doesn't mean latency will be less.

In order for latency to decrease, Vodacom needs to put bigger Engines on their trucks, or find a better/shorter route.

Am I right or is this totally wrong?
 
hahahahahahahahaha .... test and you will see :D, so to compete in the gaming scene. local should be +- 50ms (UPA wont achieve this)
So it’s an easy test, do a continuous ping to games.saix.co.za or any other
local server … then create a ftp connection and lets say upload a 10mb file
And see what the fluctuations are on the round trip on the ping. This is quick and dirty …

No, in your analogy the speed of the truck increased. But only on one section of the road, say between two specific toll gates. It should however reduce the total travel time by the corresponding amount.
