I got myself a cellc connection here is a first day comparision

iBurst good signal vs Cellc

iBurst speed peak: 0.9Mbps
Cellc speed peak: 4.2Mbps

Real world it feels about 2 or 3x faster than iBurst. There is a problem with cellc, it seems that it takes long time to establish connections than iBurst. So for example, when you browse to a page you have to wait before it starts to transfer the page (in firefox, it's the "waiting for www.google.com" in the status bar that is long for cellc). I'd say it's about 2 seconds longer than iBurst. Once the connection is established, cellc dominates iburst in speed (in firefox, it's the "transfering" status bar).

Games

So I tried some TF2 on local servers:

iBurst latency: +-70ms on a good day
Cellc latency: +-40ms (I saw latency of 35ms, and usually sat at about 50ms)

Cellc's latency is better than iBurst for local but because of the higher speeds, you are less affected by random downloads [decals, wife browsing]

But, all is not well with CellC. Peak times seem to have had a strange effect on the Cellc. The lag and through put is affected (can drop to 1.8Mbps on speed test). But that is still stable enough not to worry to much about load,the biggest issue with cellc I've had so far is that the modem keeps switching modes between hsdpa/wcdma/hsdupa. When it switches, you can lose connectivity about 20seconds as it changes modes. The biggest problem with is that you timeout. Youtube videos only half load, you get disconnected in games and you have to wait over 20 seconds before you can browse again.

It's frustrating but it only started to hit me in peak times (I also moved the modem so it might be signal issues). I've enforced the slowest connection to prevent this (WCDMA), establishing connections are still slow but the speed test this morning hit 3.8Mbps. Latency tests showed 70ms (much like iburst).

Usage monitoring uses the program you use to connect, but hidden away is a nice request for balance that will show you your balance almost instantly (like prepaid cellphones).

On the whole, I'm impressed but worried about the possible random disconnects linked to the changing of connection types. I'll do more peak time benchmarks and tweeking to see if the changing of connection types (and slow establishments of connections) is really a big of a problem as I've experienced so far.

Hmmm! Disconnects are a bitch, and not all download managers help, either. Or should I rather say not all websites allow for a download to be continued if there is a break. I downloaded a +- 300 MB file this weekend. Four hours later, with literally 3 minutes to go...I get a timeout and have to start all over again. Argh.
 
I've also been testing the Cell C for 3 days now. Although I'm at the edge of the current Cell C coverage are I get much better speeds than iBurst. At the moment I use my cellphone as a modem, forced it to WCDMA + UMTS 900 only and there is no switching to edge at all. The connection is very stable all the time. I only have delays opening web pages the first couple minutes after establishing the connection. After that all is good. To be honest I'll still stay with iBurst for a while but downgrade to smaller package simply because of the massive free bandwidth iBurst is offering during the night. But for day work when iBurst is usless I'll use Cell C.

I forced WCDMA this morning so I didn't get much testing on it. During peak times (7pm->10pm) did you get performance issues?

Nope, no performance issues during those peak times. And it was also very stable without speed degradation during the storms couple of days ago.
 
Please keep us posted. Those latencies looks promising, but the disconnect not... I'm guessing you guys aren't using high gain antennas. Would like to know if this helps as well.
 
The disconnects would definitely be a deal breaker for me. If I decide to get cell-c it will be purely for work, traveling and a back up for when iburst fails.

On the cellc forums it seems that the switching between HSPA and WCDMA has something to do with windows usb drivers. There is a hotfix for it, go check out the cellc forums for it. Like any sane person, I installed Linux. I must say that cellc on ubuntu is very very easy [easier than windows I feel]. So in theory I shouldn't worry about "switching" now. Also, windows would say 80%+ signal strength while linux is now showing 45% signal strength in the same place.

Yesterday, on the forced WCDMA mode Tf2 was jumping around in the latency - much like the telkom 3G was doing when I tested it about a year ago. It's actually quite problematic because it goes from 60ms to 150ms randomly - and for FPS its important to have a consistent ping than a very low one (provided it's lower than 100ms of course).

Currently, I'd say iBurst is better for gaming. But cellc is better at highbandwidth browsing [youtube] Let me have a go at finding a good signal strength location for cellc on linux and I can come to some conclusions.

So I benchmarked iBursts while capped [128K]

Iburst tf2 IS servers ping: +- 100
Cellc tf2 IS perver ping: +-50

Today CellC was much more impressive with TF2, it didnt disconnect once in a 3 hour play session, and was pretty consistant. I'd say that it would give iBurst a run for it's money when iBurst is not throttled. Because of the greater speeds - you can actually browse while playing and hardly notice an increase in latency. But the hassle I've gone through for the "switching" no average user would solve but my very long establishing connections seem to have gone away with the linux install.

So far, CellC Browsing is very good, beats iBurst hands down [once you get cellc to work that is, be wary of the "switching" issue]. In the gaming, I was happy with cellC tonight. But, I'm going to reserve judgement for next month. Lets see how uncapped iBurst checks out vs weekday peak cellc.

On a side note my device is only reporting a 45% signal strength. iBurst's tool is awesome for seeing error rates and signal strength, so finding the 100% for it was easy for iBurst. I haven't been able to better 45% on cellC yet.
