Just a noob trying to understand what's happening behind the curtain.
Could someone help me understand the difference between all the modems we've seen for the I717. What do these upgrades change and why have I and others seen such a difference in LTE speeds with these different upgrades?
Thanks for the knowledge.

different modems for different areas...one modem may work better for me in my area...which just got 3g last year...
some have better coverages...some get better connection using a different modem...
so bottom line a modem you are using in your state/area, my not work as good in my area......kk, which great for android users that have the custom capability to flash a use a different modem...

Hi. I recently got a white Galaxy S 2 not from my region. It uses XWKI4. I'm just wondering should I use the modem from my region (DXKI1) or just stick to this? Will it really make a difference? I thought about this because I was reading posts in the Official Firmware thread talking about which modem was better for battery consumption etc.
Its a general rule with modems is that you should always try different ones to find which is best for your region and your network.
So far I found that the best modems for me have been the KH3 and KI4. Very similar performance.

What factors do you consider in finding out which is the best one? Is there something I should monitor?

You will notice which ones perform worse than others. It will be obvious when you start getting poor network strength and/or download speeds. Some can have a significant effect on battery life.

Use an App like "speed test" and compare the perfirmance results of that versus the results of battery life, call quality, and GPS between the different modems that you try...

Trial and error it would seem. I've tried for different ones so far. LE6, LE8, LE9, and LF2. So far I found LF2 to be no good for me, and LE9 to be slightly better than 6 or 8. Your mileage will vary. Just try them all and find out which one is best. You can see the list here: http://forum.xda-developers.com/showthread.php?t=1671969&page=2
If you have a 9300 as opposed to a 9300T, I believe Mobile Odin will work for you. (Doesnt work for me yet so I havent tried this) but I believe you can use that to flash them all directly from your device, which will facilitate testing since you can probably try them all without having to physically move! Take note of your dBm readings and internet performance and let us know how you go.
Hi everybody...
Can somebody tell me which is the best modem for India in terms of battery usage??
I have already many modems like lph lps lp9 etc etc... but no use.....
I use XXLPS.. That's great.. If you want really good coverage try nelp3.. But that's not to battery efficient..
I tried that.. Bt it was also very hungry.. 40% battery drop overnight with no wakelocks or othr usage

I know this probably doesn't help much but try a few different ones and see how your signal changes. Maybe use each one for a day and determine battery drain, network and cellular signal. It varies depending on carrier, location, etc. so you need to try them out and cannot rely on someone else's best option.

I'm glad you posted in a thread instead of starting one, but with modems you need to try multiple ones to get the correct one. My modem may have better battery life and signal, but worse GPS, or vice versa. Just try different ones, no one can suggest one for you.

OK guys does or has anyone gotten some luck running a i717m note on aws band with either wind or T-Mobile? I have tried different roms, radio and mods still no luck
If someone that has gotten it to run good please post what step you took and what from and radio plus any mod required that would be awesome.
I need a stable ics rom. I have a i717m which is from bell mobility
. Thanks in advance

The author is studachris. I copied this from a thread about T-mobile, just a little way down. There are several threads infact, so take a few minutes and find them. I know the xda search function sux but googling "using at&t galaxy note on t-mobile or wind" will get you all the advice and files.
Come back if you have any questions.
"Roms and modems are interchangeable, meaning you can use whichever modem you want, on whichever Rom you want.
The blaze modem is what you want to use for t-mobile
Also the apn settings for t-mobile would probably be beneficial"
I'm not blowing you off. Learn by doing.
Here is an example:
http://forum.xda-developers.com/showthread.php?p=28940387
Capt is absolutely right. Been using the orig Blaze modem/radio on several ROMs (used mostly ICS CM ROMs). All have been stable with 3-9 mb d/l and crummy upload speeds as reported in the T-Mobile modem thread.
hey I have tried to look for it.
I've spent over 20 hours the other day/night flashing different roms and modems and searching though forums on here and google.
That is why im posting to ask if anyone has had any luck. it seem the modem I have flash really some only work with aokp rom but and the speed are good but i lost out on the s apps or I have only been able to get things working with the kid test modem it seem the blaze or blaze 4g lb7 doesnt like to work on wind while using uclf6 roms custom stock roms. but i will give that a try and see what in that link. I am just trying to get this thing up and running so I dont have to be carrying around 2 phones with me all day .
ps: I have over 7gb of rom data download that other night too its still sitting on the desktop so pretty much every ics rom and stock restore rom plus radio has been downloaded

Its seems either gave a radio for voice or data but not both. The blaze seems to work for voice but. Not so for data but the telus t989d radio works for radio but not voice I really hope the aws modem will be out soon with tmobile getting the note

Are you inputing APN settings? You can't get data without that.
Yes I have done that and the phone auto finds the apn for wind
but even after manual input still same thing. I have even tried the *#*#4636#*#* code and configure on that as well and *#2263# for the other rom still either one if the radio is good for voice or the other for data. I wish they had one that worked on both and good

My understanding is that on the I777 the modem and the kernel are combined in one partition. Although I've installed several different roms so presumably different kernels, my modem has stayed the same: I777UCKH7
Is there an advantage to trying different modems? How would I do it?

Can't believe you have flashed several roms and the modem hasn't changed. Most of the newer roms I have flashed have included the latest ucmd8 modem.

If he's been flashing AOSP-based roms they won't change the modem, so it's conceivable he's had the same modem across different flashes.

I was on supernexus for a while now I'm on carbon. My modem has always remained the same. That, however, is currently the least of my problems.

I may have misunderstood what I read. I thought it meant the modem was always linked to the kernel so it can't be flashed separately. Now I'm just plain confused so don't mind me. ;p

You can flash them separately because they aren't in the same partition.

I'm confused about why you'd pick one over the other. Are you looking for newer/faster? The best one for where you live? The one that runs best with your Rom? I had a lot of problems after I tried to flash the ucmd8 - May have been coincidental but either way the modem didn't work.

Can someone direct me to information about modems? The development thread referenced above lists a number of modems, but doesn't tell anything about them. Is one better than another? Is the latest one always the best one? The development thread used to have a map, but it has been removed. Are some modems better in some areas than others? I am trying to find the one in my area (central California) that has be best reception in a limited coverage area.
I am running the latest version of AOKP dated 6/24/13 and the baseband version (modem?) is i777UCKH7.

You answered your own question right there - flash them all and give each one about a day to see how your reception is. The map you're talking about was removed ages ago because it became corrupted.
In the end no one can tell you which one is better for you; just because it's the latest modem doesn't mean anything at all, in terms of reception/quality.

Thanks. It sounds like there is no reason to start playing around with modems unless you are actually having reception issues and then it's totally trial and error. My modem (UCKH7) seems ok here (southern CA) so if it ain't broke...
