What are the advantages of flashing a new modem? Will certain modems get better service signal than others? If so, what seems to be the best modem which gets the best service signal? If not, is there any other way to improve the signal? I get no service in my house, so I usually use WiFi calling, but I kinda fell in love with ICS and CM after flashing them and would like to try to keep them. Thank you.
Nearly as many opinions on modems as there are threads on them. Search will reveal both.

Hi, im from brazil. i have some problems with network signal.
in places where friends of mine from the same network operators (vivo)
have a full 3g signal, i cant even get an edge. but in open spaces i get a good signal. im on CM7 nightlys,
baseband I9020XXKB3,
and my build is GRJ22.
signal on -95dbm now.
my questions are:
can i solve this problem by flashing a new radio such as XXKD1?
what really is the function of the radio?
does the contry that im on now request a diferent radio?!
thx for the attention?
Radio effectiveness differ from user to user. Depending where you are. What might be a good radio to me might be bad to you n vise versa. Unfortunately you will have to try them by yourself and judge.
For me kd1 gives me a better reception but slightly more battery drainage than kb3. Some users reported better data speed. Try it out and see.

thx for the attention man!
i'll try them all.
another thing, do you know if the radio already comes with the ROMs
or i would have to flash it always apart?
i was wondering if anyone knows whats a good radio and/or ril combination to optimize my reception here in the philippines. just moved out here to finish my education since california is getting pretty damn expensive. i'm using the current recommended radio for the rom i'm using but reception for wifi and 3g are all over the place. sometimes 3 bars on network but 1 bar on wifi and vice versa. i cant keep a constant network connection and my wifi signal is really weak regardless of how close i am to the router. i considered flashing all the radios to find out but i dont want to continually risk bricking my phone but if i have no other option, i'll have to do just that. any suggestions/tips? thanks guys.
The Wifes Infuse is having problems connecting in basement at work. she is on stock build from ATT. Any idea?
Could be a low reception area.
^^^ right. could be a low reception area. although if you're willing to tinker, and being a member on here, i assume you are... you'll find that each modem acts differently in different areas. the "best" modem for me in southern california in my single story house might not be the best for you. so now to the tinkering issue... try flashing different modems, let it settle for a while and see which one works best for you. i actually have several modems stored in my phone so if i'm not getting particularily good reception in a certain area, i can flash another! good luck tinkering!
And to flash modems, you'll need to root, flash a custom ROM or get a custom recovery (red one I mean), and play with flashing modems.
My i535 is on a rooted, unlocked stock, 4.1.2, baseband I535VRBMB1, with TWRP 2.5.0.0. My primary concern with the phone is it's spotty reception. I have thought that newer basebands would be the better ones, but from reading here I gather that is not always true. Can someone point me to some information that would help me choose and install various modems to see if there is one that will do less signal searching. Right now I have disabled LTE on my phone and that seems to work better. Maybe that's as good as I can expect.

FYI there isn't any modem that is better then the other as it all depends on your cell coverage where you live and how your phone responds to the modem.

Thanks, I guess that Verizon has to build modems that work for the "average" situation. If everyone lived in the same coverage area there would be a lot fewer complaints about dropped calls and poor connection. I know that it will take a few days for a modem to learn how to connect in an area. It's not fun to be stuck with a phone that people tell me is breaking up when I call them. I came from a Droid X and I'd say it had a lot less problems with calls. I have always used antenna signal amps in my vehicle and that does help. (Wilson Electronics).

The verizon gs3 has signal issues. Im in a very well covered LTE area and have issues with signal. Doesn't matter the modem. Its the phone itself.
See that proves my point that you get varying results depending on location and phone. While you got problems in a well covered area of Colorado, I get problems I certain bulidings in NYC that I had no issues with my previous phone.
I get fantastic coverage (but unfortunately not on AOSP) and I'm on a rather old modem. I figured not to mess with it because I know they're really touchy

I have searched this forum, but couldnt find any thread with this specific issue, however there are some threads regarding the different modems available... have browser them but the sollution for me is still to find
Using nightly CM-12 with included modem, global OPO on the Telenor network in Sweden(2100Mhz for UMTS, dont have LTE on this SIM).
I installed CM12 as a troubleshooting-step after I tired using both the stock CM11s and CM11 nightlies. CM12 gave me the best signal strenght over all.
This thing is, I can get a good signal so the phone seems to be able to communicate with the cell-tower on the frequency used by the nerwork... but it is very unstable... Jumping from H/H+, from full to none signal-stenght. Also seems to change Cell IDs, this is even when the phone is stationary...
Even if I have an OK signal on H/H+, trying to use the dataconnection sometimes works, but often it would result in time-outs etc, even if the up/down arrows in the indication icon shows activity... Also sometime trying to use dataconnection when the signalindicator looks OK, it will drop to nothing... And speed-tests gives very poor results...
Dont really know much about how the physical layer for the mobile networks work, so dont know how to interpret this behaviour...
I have described these symptoms also in the modems-thread in the General forum, but having tried most of the modems, this is still the best ROM/modem combo...
Dont know if related, but using a WLAN-connection the HSPA cell connection is stable at around -103dBm... no flapping...
I feel that I have tried the most often recomended action with no appearant improvement, dont really know what to do now? Change modems, try to unlock additional bands... Any suggestions?
If any developer wants me to try any thing, or provide any more information I will try to do/supply that!
Update
Took the phone out to the local shopping center and got some surprising results...
Consistent -59dBm and around 20Mb/s downstream on UMTS.. So this beggs the question, why is it flapping up and down at home, where an old galaxy s3 mini sits comfortably at the same usable signal-strenght most of the time on the same network?
Is this a modem firmware thing, or antenna?
