Modem Results By Location

Sorry if I am duplicating a previous post as I was not able to find a thread with this information.
I'm in Miami, FL (specifically in downtown and Dadeland area) and have not found the right modem yet. Bandwidth speeds, GPS accuracy, and battery efficiency are the most important for me (and just about everyone else ).
After reluctantly turning off HSDPA (to conserve battery since it keeps swapping from 3G to H) my current combo seems to be OKAY but not great. I would like to hear from others in the Miami area. I suspect that different kernel/modem combos will have better results than what I am using. Any suggestions? I am curious to know what is working out for others here. I have tried several modems but currently I'm using the Phoenix 3.0 ROM with Speedmod Kernel and JL2 modem. This has given me the most efficient battery life to date but bandwidth is around 1.7kbps/500kbps and GPS accuracy suffered greatly with this modem.
Posting positive results and what kernel/modem used related to major cities or even by state could be useful to all users. Obviously results from different ROMS will vary but If nothing else it would be a point in the right direction for those of us who do not get good results with our current modems.

You can try to use the band toggle app in my sig. HSPA is 850Mhz and 1900 Mhz. You can choose whatever band/bands you only want to use.

Thanks! I've been manually doing it since I did not know about the app
Now about modems

The app is just a quicker way to access the band select secret menu. Just so you know... it doesn't persist through reboots. And I'm not sure if this will help or not, considering those same bands are for 3g as well as H. But maybe worth a try.

good idea for thread.
Everyone seems to get differing results with their captivate/modem combo's and i have wondered whether it is more related to Geography or the Specific Build Models or combination of both. My suggestion is to try JK4, JK3, ZNKP1, and TLJL3. I had read great things about JL2 having accurate tracking but for me it was virtually useless (good lock times horrible tracking....it even missed my first turn and went a block and a half before realizing i had turned)
With this in mind i think it make since in addition to geographic region to also post the build # of your phone.
Best Modem's for Fast Locks & Tracking for me are:
1. JK4
2. ZNKP1 & JK3
3. TLJL3 (although this is a big dropoff in tracking performance from #1 & #2)
Location: Central Illinois
Build: 1007
Rom: Firefly 1.5
Kernel: Speedmod O
Modem: JK4 (excellent tracking with this modem/kernal/rom combo)

Location: Surrey, BC, Canada
Rom: Continuum V1.2
Kernel: Paragon RC2.0
Modem: ZNKP1 (Best Speed, Battery Life & Signal)
My second choice for modems is JK3 but battery lift is not as good as ZNKP1. JK4 was great except I found 3g/H would sometimes lose connectivity.

In Delaware, I got worse battery life on KP1 than on JL3 or JK4.

South Florida here as well... JK4 has been good to me but I am also testing JL3 now since some say it is better on battery. Since I just loaded it, I cannot say if it is better than JK4 yet or if it offers better battery. Will know tomorrow with my overnight standby test. If I see no improvement, I will probably go back to JK4.

Location: San Francisco, California
Rom: JPY Roms (Darky, Doc, Serendipity)
Kernel: Speedmod, Paragon, Glitterball, xcalibur
Modem: JL3 > JK4 in all cases. For me, GPS was the only issue I worried about since I drive a lot and tend to get lost even more, but JL3 has great connectivity and battery life also.
My only qualm with JL3 is that when I turn on the phone while it is plugged in, the SIM card doesn't get read, but that's a really minor thing for me. I've simply developed the habit of unplugging the charger before I reboot the phone. I haven't yet tested the Chinese modem.

Ft lauderdale, fl here
Phoenix 3.5
1009 build
I drive around alot including the miami area for work. Had good results with jl2 better with jl3 jk4 had great gps but lacked in phone reception for me. Right now i am running kp1 modem and testing battery had horrible battery today 4 hrs with minimal use using fb2 kernel. Switched to speedmod and testing it out. Didnt have good gpa with fb2 will test it with speedmod and update later.
I threw my phone into the flames and it was reborn

I have a feeling the modems are gonna be like the radios from back in my WM days. Your results for different modems will depend on where you are in the world and less on what rom, firmware you are using. I am gonna move this to the general section as this is not really about development.

4G rooted inspire speed is slow to fast

I have an Inspire that is rooted,and after 5 different Roms for1 day each, I have settled into the revolution ROM and it really works great.I have my unlimited plan4G (most of the time I think)and I have my tendering. My question is when running the "sweetest.com" application I get 331 down and 783 up inthe evening and 2592 down and 1447 up in the morning until about noon,is this network congestion? Is there a different radio mod or flash or something that software locks the radio in HSUDA mode or whatever is making it that fast?? If anyone knows of a setting or .apk that addresses this or a setting possibly I would appreciate it,or an explanation if its not a tweakable thing might save hours of obsessing over trying to fix it.Thanks, Vegas

Yeah, the slow speeds at times are due to all the iphones tying up the network.

Funny, but I notice my speeds do the same. But most of the time it's relatively good.

I definitely think this is network congestion. My best speeds are late at night (usually about 2.5 down/1.5 up). Most of the time my upload stays about the same (between 900k and 1.5mb), but my download goes anywhere from 400k to 2.5mb..or lower

So 2.5 down is the fastest I can expect and the radio with the Revolution ROM is the Best one I could be using? I have heard 4G was capable of 6mbps,No..Anyone?? Is it gonna get better in phases,anyone know the truth?Vegas

Gingerbread Speed Issues / Results

I have been back on GingerREMIX for about the last week and have noticed an issue with speeds over 3G / 4G / WIFI. I listen to Tune-In just about 24/7 and with BAMF 1.6.3 (Froyo), it never buffered. It seems with the Gingerbread leak that we have, it buffers over 3G, 4G and WIFI every 20 minutes or so.
So I have put together a little test sample of data speeds over 3G and 4G (I am working on WIFI results as well). The tests were performed on two different days at roughly the same time as well as in the same location to try to capture a fair sample. I will also note that absolutely no apps except for the speed test app were installed over the base ROM when testing.
I uploaded all of my results to google docs to make it easy for everyone to see.
https://spreadsheets.google.com/spr...QjR5ODNNWkluaXJOenc&hl=en_US&authkey=CNHdsMQE
Just something to think about before making the leap to alpha GB.
Disclaimer: In no way does this reflect on the quality of the BAMF ROM(s) as I have experienced the same type of issues on other GB based ROMs. It more or less comes down to the alpha build of GB that we have.

Interesting. Thanks for the "side-by-side" comparison.

Please don't tell me you used speedtest.net mobile app to get these results.
If you did, you should read the other 100 topics about Speedtest app not working on GB, you will in fact get normal speeds with GB just need to use a different speed test.

I really think that the leaked radio has more issues than just the possible bricking. When on CM7 GB, I get normal download speeds in the 12-20 mbps range, same with any froyo rom, however, when on any of the roms that need the leaked GB radio to work, I get horrible speeds. Netbook tethered to phone, Pandora/slacker streaming, YouTube streaming both normal and HQ videos. There is a definite and significant drop in download speeds.

Interesting, just when I used the leaked GB radio on Das BAMF everything ran fine with plenty of speed. Speedtest (Not the app) showed normal speeds and I never had a problem with downloading/streaming anything even the MR1 PG05IMG.zip to send me back to froyo downloaded in a minute or two (400mb file).
Also, Pandora didn't work on GB so I don't know where you got that from.

The 1.5.6 version of Pandora ran well, I couldn't get 1.5.7 to work though.

[Q] NexusMod ICS Zero Beta 7 UCLD2 Radio slowness

Yes a noob to Android and yes, first post
Before my quick question I have to say thank you to M0D1441 for this ROM (and his contributors - it is absolutely amazing, and by far - the best ROM out there for Galaxy Skyrocket I727 users.
Flashed this Rom from stock I727R Rom last week and have had huge success with it and cannot wait for the update to this Beta 7.
However, since flashing the UCLD2 radio I notice significant slower speeds compared to whatever the stock was using. I have followed all procedures correctly, am able to auto switchover from LTE and HSPA+ and have had no issues with this ROM that anyone else has reported other than significantly slower speeds.
Max down on HSPA+ has been between 5 - 7 Mbs with upload at 0.2-0.56 Mbs and LTE down: 16-22Mbs (which is not bad) but have full bars and 2.78 up.
Even my home WiFi (802.11n) connection suffers from this new radio with dowload @ 18Mbs and up @ 0.56 compared to stock ROM speeds at least 38.6Mbs down and 3.7Mbs up.
My speeds with all connections with stock radio were, at bare minimum, double to what I am getting now.
I have flashed the UCLD2 radio a few times following procedures and still no change in speeds. I have read nightmare stories about switching back to older radios on the I727R and am nervous to do so.
Wondering if other Rogers users have experienced the same issue and if need be, what radio change to?
What was stock radio on Rogers I727R and is it compatible with the NexusMod ICS Zero Beta 7?
Is/can this UCLD2 radio be not fully compatible for Rogers customers in Canada?
Thanks a million in advance!

I'm on att and I haven't noticed a drop in speed I know its not Rodgers but I can't imagine its all that different

Keep in mind the modem is for AT&T, so not surprised you're seeing slower speeds on Rogers. Also, the modem, a.k.a. Radio has no affect on Wifi as Wifi is part of the kernel.
Bottom line, your experience is more than likely going to be a "best effort" at best; think of it like trying to install a Ford part on your Chevy car.

Thanks for your input. Yes, I figured this radio may only indeed be for AT&T but it is such a great modem/radio. My battery life is far superior with the UCDL2 as opposed to the stock KJ7 radio. Guess it's a toss between speed or bat life
As for WiFi, I realize this radio should have no effect on it but it is definitely slower with the UCLD2 modem. Strange - I will have to try and get this under the microscope and see how/if/what is effecting it.
This may be a dumb question (sorry) but can you use the stock radio with any ICS ROM or is that just going to cause nightmare issues?

Wow. Really? That's what I figured would happen for me but... not happening. The only thing I did not do was install busybox but I can't imagine that would make any difference to the radio.
I just want to make sure i am not damaging my phone by using this modem. maybe it just needs some settling time but it has been almost a week.
What kind of speeds are you getting?

I've had trouble with both leaked radios. Went back to GB/GB radio until a new leak shows up(hopefully rogers leak)

I totally hear ya. However, I have noticed something interesting which completely makes sense. After having the modem settle for a week now I have noticed that my daytime speeds on HSPA+ are slower compared to daytime. Now, Daytime on average is 9.51Mbs down and 1.27Mbs up (which is actually not bad) compared to night (after 9pm) getting an average 13.72Mbs down and 2.73Mbs up. I can't really complain as this seems the norm for GTA on Rogers.
LTE daytime speeds have now been an average of 23.7Mbs down and 3.78Mbs up compared to night time speeds of 31.2Mps down and 5.71up. And, this is on the outskirts of LTE in the East end!
However, my Wi-Fi speeds still suffer. My LTE speeds are far exceeding anything I get through my 802.11n router which maybe something in the Kernel which I will check out.
So really, I can no longer complain Guess it just took some time to settle in the device.
As for the Rogers ICS, according to this article: http://www.androidcentral.com/samsung-reveals-us-ice-cream-sandwich-update-list , " The big picture is that if you've got a Galaxy Tab or Galaxy S II-class phone, chances are you're in line for an ICS update later in the year."
Ouch! Yet no announcement has been officially been made for North America. And, don't forget Rogers will need to test and ram it full of their bloatware before we see it!

Try LeeC's UCLA3 modem ported for ICS. http://forum.xda-developers.com/showthread.php?t=1567213
It says UCAL4, but it is 3. I found UCLD to be unreliable, and LeeC's fix is wonderful.
Good luck !

Thanks. I am going to give that one a try and see how it performs this weekend. Thanks for the link!

Advantages of the new baseband

Hi all,
Having updated two over to the new baseband (June 2011 to March 2012) and sticking with stock on one while using cm7 on the other, my experience has been as follows:
* battery life is the same. Cm7 much better than stock but then it's cm7. I went from Weapon to stock 2.3.4 and did not see a noticeable difference.
* GPS fix is a function of well written GPS.conf. I see a slight improvement in lock from cold start but nothing outside of normal variance.
So what was the purpose of the new baseband? To me it is now appearing to be just a date change in a field . (Obviously there are differences otherwise call audio would work without any changes).
Thoughts? Note that I had to subtract wishful thinking to reach my conclusions.

Huge signal strength boost on my end. My dorm I used to get no signal. Now I get two to three.
Sent from my paranoid Nexus 7.

At least for me, the GPS was massively improved. GPS fix is not purely a function of well written GPS.conf.
On stock 21e/2.3.3 - my GPS barely worked. It was intermittently better on cm7.x - but it was still a POS.. rather .. GPOS (global piece of.. )
On stock 21y/2.3.4 - my gps was massively better, but over all it was like a whole new phone.
On 21y baseband + CM7.2 it works really well, and WIPER/A-GPS works as long as I have data connection.

There are also supposed to be battery life improvements - but this only affected Stock Rom, CM7 was not noticeably affected.
Furthermore, I find that the newer SIM.. TM9177 works .. whereas with 21e.. only the TM9073 SIM worked..
I have also found that my HSPA+ connections are slower - but more reliable.. e.g. now I get a solid 5 mbps down, between 1 and 2 mbps up - with 21e - I occasionally has 10 mbps down - but it was very inconsistent - it would connect/drop all the time - and not necessarily a function of signal strength (e.g. standing in one place the signal would vary a lot) . 21y just plain works better.
One other change - I used to be able to use Faux123 kernels on CM7, but now I can only use Stock CM7 or Trinity - the Faux123 drain battery among other problems. No idea.. it isn't a bad flash, but my phone went from tolerating Faux123 to absolutely refusing to use his kernels.
That being said, it is widely reported (without citations!) that there was poor quality control on the LG manufacturing of G2x.. so the phones apparently vary quite a bit as to what does/doesn't work. I would say my phone never ran 'right' on 21e.. but it feels 'right' on 21y.

I wish I could use the new baseband, I get less disconnects with it.
However I can't live without bluetooth calling, and cm 7.2 for some ??!?!?!? reason still has not fixed the bluetooth bug.
