Yes, but which value is more important? Ping or download speed (though I'm 99% sure the answer is download speed but I ask just to be sure).

By the way, other people told me KB3 should give me lower download speed, just like I posted, so its strange you tell me otherwise...
[Galaxy S I9000 Android Development] gokussjx:
Most people would get Higher download speed with KB3, many don't get even the network with it. & many others do, but get lower speed. Its controversial, & relative.

Try taking average of tests.

If you are into streaming, & you watch videos online, or play online games (with/without tether), better PING is more important.

If you just surf & download, go for higher download SPEED.
[Galaxy S I9000 Android Development] TheeWolf:
Thanks for the answers.

For some reason I flashed KB3 again and speeds were amazing (relatively).

The results (Average of four) were about:

Download - 260 kB/sec

Upload - 80kB/sec

Ping - 105msec

Its strange it suddenly turned from a low download speed to a high one, but it seems for now this will be my modem.
[Galaxy S I9000 Android Development] gokussjx:
As expected.

I think the best feature of these modems is not speed but call quality. For those carriers that it works on at least...

[Galaxy S I9000 Android Development] DarkSorcerer:
Question:

In any ICS rom I install, every modem I install from Samsung (JVT, JVU, JVR) ends up loosing data connection. I mean, the process is:

- boot device, data connection ok

- sometime after, data is disabled (without any user action)

- data doesn't return

- reboot the device

- data connection ok.

With these modems, sometimes data connection disables itself, but returns without me having to do anything.

Do you know why this happens?

P.s. Yes, I've wiped, went back to GB, flashed stock ROMs, etc, etc.

I'm really annoyed that I can't get KB3 or any of the other XXxxx modems working. I've tried everything I can think of, even tried flashing different bootloaders (but the GB bootloaders seem all to be the same just with different names).

Then I changed the modem.bin with that of KB3, that will install just fine.

For me on "ICS 333 2.0.1" ROM the KF1 Radio worked - but only after flashing it twice.

After the first attempt it showed me no baseband and no signal but after the second one it worked. Signal strength seems not very different from JVU but I will test more soon.

I flashed it because I need a Radio that handles handover quickly when I am travelling in public transportation where I use the device most. Let's see how it handles that..
[Galaxy S I9000 Android Development] dan9550:
I think i remember reading somewhere on the forums that these modems are not fully compatible with 2G or something. Are there any issues or downsides to these modems at all when using them on a Galaxy S?

Or does everything work just fine?
[Galaxy S I9000 Android Development] groksteady:
It seemed like one of the great features of these modems was automatically switching between HSDPA and 3G. Sorta seemed like a smart mode, switching when needed.

Anyone else using these on the JB ROMs? I have KJ1, right now on pawitp's 0723 build, and it seems to stick more to 3G. I get H, but only sometimes, and never like on ICS, where it switched a lot. I'm about to reflash KF1 and start that over...

Yes. When you change modem software, it does not affect the wifi driver which is built into the kernel. So wifi should not be affected by a modem change.

I have a question.

As stated in the OP, when data is enabled (or also when not?), these modems automatically change from 3G to H when needed (UMTS to HDPA, right?).

Does staying in 3G better for the battery then staying in H? Also, doesn't this switch consume battery as well (everytime it makes the switch)?

The switch should just happen automatically. Very rarely will you see 3g unless you turn hspda/hspua off. It won't use any more battery than it usually does searching/connecting to data network.

Best Modem for me in Brisbane, Australia

I decided to use XXJW4 after trying many of the modems available. UCKJ1 came a close second, but XXJW4 really was the best in terms of reception (which is very important to me) which obviously affects speed and battery life.

The best reception I was able to get with UCKJ1 was 25 asu. As you can see from the screenshot, the best I got was 31 asu from XXJW4. I just about fell over

I know that these modems are all a bit iffy when it comes to location, provider etc, but I hope anyone else living in Australia is helped by my (extensive) research

[Galaxy S I9000 Android Development] oswade:
3 tests in melb, vic. also using optus. kilobytes/sec (using speedtest.net app)

Reception is only 1 to 2 bars in my room (didn't check dbm), so generally pretty ****/slow!

test 1: ping 107ms, down 48.2 (for some reason didn't go to H), up 31.2

test 2: ping 116ms, down 325.5, up 36.1

test 3: ping 205ms, down 493.8 (awesome, but i moved my phone slightly during the test and the signal went up to 3 bars, so the increase is not a surprise), up 45.1.

Can't be bothered reflashing jvu, this modem seems very stable, at least equal to jvu and all functions work.

NB: this is stock JW1, not CM, and I did use these build.prop tweaks http://xdaforums.com/showpost.php?p=5123531&postcount=46

ro.ril.hsxpa=2 (on stock rom this is 1! apparantly optus supports hsupa as well as hsdpa).

hsdpa cat = 8

hsupa cat = 6

ro.ril.enable.dtm=0 (apparently optus does not support dtm, or does a shoddy job of it).

EDIT: is optus' upload usually this slow? I can't remember how it was on jvu :confused:... i might have to flash back to check after all.

EDIT2: ok, jvu was getting about the same in download tests, but upload went up to about 200kB/s. However, i feel that kf1 has a more reliable connection from this limited experience. I'm flashing back to kf1 now to test upload speeds once more, to see if they can reach 200.

EDIT3: nope, my upload speed still seems to be locked under 50kB/s :(. I will try again in better reception (my room sucks ****), and give this modem a few days trial. Phone call quality is also worth testing. Then I can truly consider if it's a better daily driver than JVU or not.. The upload speed could be a bit of a bummer.
[Galaxy S I9000 Android Development] Kocai:

[Galaxy S I9000 Android Development] s3icc0:
Reading this thread and I am not sure any of you was able to give satisfying results ... or maybe it is because there is no unified way how to test these.

The testing should be performed on more than one place and with different networks on like this (based on your previous results):

1) provide country and rom used

2) test JVU - KF1 -JVU - KF3 - JVU - KF1 - KF3 in this order on each location (this is because denying the null hypotesis the modems are equal).

3) test only 2G - only 3G - only HSDPA - (for those having the chance to test in places with poor signal test automatic switching 2G/3G/HSDPA).

4) have different location for each test series - in a building, in an open place, in the center of the town (near high buildings).

5) Test your BT (go/nogo) and WIFI (dl/up speeds, ping, signal strength in dBm) at home.

Results:

Provide us with signal stregth in dBm for each test series.

Remember the network is changing its capacity every few minutes as people are moving and not sleeping ... so each series should be performed within max. 15minutes.

Can provide you with an unified test report.
