[REF] 3UK radio(modem) tests

As I quite like running tests, and i am a bit bored, here are the results of me testing my Download/Upload and signal strength with different baseband versions.
Phone was kept in just about the same position the whole time, and no extra tweaks where applied.
The phone had 80%+ battery at the time of the tests.
All other data about rom/kernel etc is in the spreadsheet.
As I dont have random sims for the other UK networks on hand I cant compare
And onto the link
CLICK HERE​
Notes:
For dBm higher(closer to 0) is better
asu measures the same thing, but on a diffrent scale, higher is better
Both download and upload speeds are in kB/s (Kilobyte Per Second) rather than Mbps (Megabites per second) (8 bits to a byte)
I don't have a low signal area on hand so I cant comment on data speed or signal quality there.

hello,
so the KE7 baseband is better than others baseband?

The "best" baseband version is very much dependant on network, and where you are in the world.
In my testing its the best for me on 3UK in england.
The best way to find out which is best for you, is to flash a few and do some basic speed tests, I recommend the speed test app here
I was getting pretty bad speeds with the KG1 modem/baseband/phone and I have seem some other 3UK user note it, so I though I would do some basic tests.

Do a speed test, turn it off, do a test.
If your download speed is faster with it off, your network doesnt support it.
Or google "network name Fast Dormancy"

The KE7 Radio for me on 3UK doesn't work well though. It does that thing where it gets stuck on upload.
Changing APPN to 3internet and turning off Fast Dormancy helps a little.

Do you have the apn settings for 3internet?

And for me, no matter which Rom and kernel i use, the download speed is less than the upload speed. Any idea how to rectify this.

Spiffy, the other thing to-do is look at which radio's where shipped with official roms in your region! As they might be more inclined to be better tuned for the area.

Before anyone changes apn from three.co.uk to 3internet, I have read that the original .co.uk one on our phones allows roaming 3g when out of the 3 network range. 3internet does not.

Not that I know of, use this app to edit it on the phone, needs root

Its really not a reliable Test in my opinion as I tried it .. Am on Vodafone Uk
I am on the KG1
Under status Mine will change between (73-87 dBm) and (17-20 asu) If you keep looking at it
I get around between 2 -2.5 mb downloads and 1 -1.5 mb upload
Just a thought on a different network

Best modem for Europe @CM7 ?

I have CM7 Nightly #42 and I'm looking for the best modem for Europe, Germany mainly. I can't get 3G to work with JVP/JVQ. Would be nice if it's easy on battery, too.
Any suggestions?

Great news that it finally has been resolved! I miss Cyanogen (used it on my G1 sold 10 months ago, but now I'm on stock Samsung ROM), maybe it's time to do the switch.

Italy For what is the best modem? I thank you in advance CM7 "Italy 3"

I'm on #61 and still no 3G... Nothing in release notes of #62 indicating any improvement. Perhaps I should flash JVK modem back?

You can have 3G only by using the settings menu and not the widget

I don't use the widget. I keep 3G on in the settings, but all I get is H/3G flashing on status bar from time to time with H staying there for good.

Since "H" is better form of "3G", it looks ok.

ugh... I'm turning red now, good you can't see it... THANKS!

H stands for: HSDPA, 7.2 Mbps
Basically means that you have access to high speed internet on your phone.

KG3 modem. Issues adios!

XG3 modem. Finally a modem that seems TO fix all issues like data connection lost, 3g,h,h+ troubles, modem hang up while calling with low signal and many other.
In the past, looking a webpage or using xda app was always return, retry, return, until the page was loaded fully.
Now seems to be zero latency modem.
I must test if the modem will prefer 2g in low reception or if will try instead to keep 3g I'f data connections are required.
What do you think about this modem?

Have to agree with kawa636r , it is the best modem out so far. KG3 performs flawlessly in Telstra NextG network compared to previous versions where data connection was lost.

i thinks its time to upgrade to KG3 and find out!!

Thank God, I live in Italy too finally a modem that made my phone usable to call and to navigate. I've got the Desire Hd before and my data connection was perfect, with Sgs it was a bit disappointing, now it's better.
I have H3G italy as carrier

This is great news!!! My only gripe was the poor wifi signal. Anyone know if that's improved too. I am going to test myself but i have 6 hours remaining on the download. Wish it'd hurry up!!!!

Just wanted to report that the kg3 modem seems to have fixed my problems, as well, and I'm in the Philippines on Smart telecom. Now if only I could fix the carrier itself, somehow...

What ROM's and kernels are you guys running with the new KG3 modem ??
I'm on VR2.1 with Ninphetamine-2.0.1 kernel, currently on KG2 modem.
Not having any major issues, just some drain on one of my exchange apps.

Mind you the kernel is KF3. Anyone know how to check the modem? My baseband and build are both KG3.

Cheers!!! Wifi still not fixed then cos i'm on the KG3 modem.

What exactly is your problem with wifi? If it's low signal strength, I think that's just the GS2 under-reporting the connection strength. Even when it says I have only 1-2 bars of wifi signal, the connection is still fast.

Modem has nothing to do with WiFi signal. That's in the PDA part of the firmware. It will only affect 2G/3G/3G+ strenght and call reception.
That's something I've learned on XDA when I had the first Galaxy S.

[Guide] Must Read ! Modem & RIL

What is Modem?
Modem/Radio/Baseband is basically a driver which receives and sends Mobile Network signals as well as handling switching between GPRS, 3G, HSDPA etcodem?
Are they firmware specific?
Modems are not firmware specific. You can install any modem for the Galaxy S3 to any firmware, (*** T variants have their own modem version for network compatability),
Why is a good modem important?
If your phone has to constanly search for signals and lock on to them it not only gives you a poor call and data quality but also drains your battery.
Where I can Download different Modems?
You can check it here
What is RIL?
The RIL is a program between the Radio and the ROM. It communicates with the hardware and supplies an interface for the ROM so it can use the hardware.
What does it mean?
Think of it as the device driver you have to install to your PC when you're adding a modem, so that the PC would recognize and work with the modem. In short it acts as a translator between the hardware and your software.
How do check if I have a compatible Modem & RIL on my phone?
There is a certain app on the market called GetRIL, it attempts to match RIL, (Radio Interface Layer), with your modem for a more efficient operation.
What will a modem with matching RIL give me?
Simple.
You will have an even better network connectivity (eg. E, G, 3G, H, H+). For example, I am now consistently getting a H+ connection where previously I would only be getting H at best. This will obviously improve your speeds during browsing, the more chance you have for Fast Dormancy to work as it should, thereby saving battery
Is it Important?
That of course depend you users. If you think its worth a try.
So is it Okay to flash different firmware on different Regions?
That depends on the user.
How do I Check if I have a compatible Modem - RIL on my phone?
There ia an App on the market called GETRIL wherein it checks your modem ril compatability
"Check Attachments Below"
How do i check if I have a good signal?
There is an app on the market Network Signal Pro wherein you can monitor your connection signal for stability
Does modem affect Wifi?
Certainly Not, wifi is controled by a kernel not modem
This should be helpfull to you guys especially those who are flashaholics and newbies
Please Press Thanks

*Reserved*
Should I make this a Wiki?
Is this relevant?
What do you think guys?

Its relevant if RIL makes a difference to the majority .
But as you know the majority probably have the wrong RIL i know i have .
But yes either added to the stickies or the Wiki.
jje

Of course it should be a wiki, I've already done these process and I realized that i was with the wrong RIL
IDK if it's just an impression but my conection seems to be a little faster now
thanks for this guide! :laugh:
Edit: I was also having issues with BBS with the statements "No data connection" and "No or Unknown Signal" with the ration on 100%
I'm checking if this will be solved with this fixing of RIL

Yep certainly does.. I think so too..
Having a compatible Modem RIL really is an advantage compared to flashing without checking Modem-RIL compatablities...
RIL acts as a translator between the hardware and the software ...
So get a smart translator. The one who can translate well. =)

I get this :
What to do?
Network is fine and H+ also works but I want to try this
I'm on latest leak firmware ELK4

Can anyone make tar modems flashable via odin?

Good guide, maybe add that I9300T modems work fine on I9300 phones and the way around as this question comes up quite often in Q&A as well as the modern collection thread, maybe also link that collection to your guide.

Hmmm... speedtest shows me 5.72Mbps down, 1.54Mbps up (and signal is not the best in my area, I have approx 29%, -91dBm according to Network signal)
According to GetRIL - baseband XXDLID, RIL - unknown
Now lets put matching RIL.... done... reboot... done and, lets re-check speed: the result is exactly same.
So, is the matching RIL a must, or a maybe?

Same for me. A mismatched 9300t modem gives me faster speeds than an LID or LIB modem matched. Matching RIL made no difference to my speed tests.
I doubt it's a must

Greater network connectivity (eg. E, G, 3G, H, H+). For example, I am now consistently getting a H+ connection where previously I would only be getting H at best. This will obviously improve your speeds during browsing, the more chance you have for Fast Dormancy to work as it should, thereby saving battery
As stated on my post.
Importance of Modem RIL depends on you users.
Just be reminded that RIL acts as a translator between your modem(hardware) and your software(operating system)
SO if anything is not matched would there be discrepancies?
So we are talking about stable connectivity thus resulting greater improvement on battery and speed on that matter.
H+ is much faster compared to H, 3G, E.
I didn't say its a must so you decide =)

Mobile signal crazy in every custom ROMs

In the battery stat of MIUI, the network signal is very stable (in my case almost always green)
But with allcustom ROMs the signal is jerky.
We can see for exemple here in the Fedosis's great MM ROM :
https://forum.xda-developers.com/showpost.php?p=72931400&postcount=4514
Here in newer N roms :

Also, in my case, after some days of use, i sometimes totaly loose network connection ! (quite annoying for my boss... and my wife )
It should be great to fix this problem for our custom roms.
Do anybody have an idea ?

i do agree with you having very low signal levels in N roms

Here in India, certain telecom operators do not have sufficient infrastructure for high signal reception or coverage. MIUI do not truly show the reception strength while custom roms are partially accurate

Set network preference as 3G, you won't see any network drops then.
