After using xxkb3 i can't go back to using uckf1... anyway here is speed test on my nexus s optimized for SaskTel 3G+ (i refuse to call it 4g).
[Nexus S Android Development] ZeppeMan:
Just flashed my I9023XXKD1 -> KF1 through ADB. Everything went well. What I instantly noticed is that my signal strength is better.

PS: I'm from Belgium.

My internet connection is 25mb down and 3.5mb up.

KB3 with HSDPA tweak and even with this "H" doesn't appear in my status bar
[Nexus S Android Development] ChargingPaladin:
Most roms don't show the H. Check your connection info for the truth (settings > about phone). You should see HSDPA.

Witch baseband gives me better network in Portugal?
[Nexus S Android Development] kibmcz:
yep many i9020a users wanting non capped radio... i don't get why it was capped in the first place. It's a unlocked developer phone.

For me i seem to get better battery life on xxkb3 than on uckf1. Anyway its 13% cell standby.
[Nexus S Android Development] idelgado782:
I had previously flashed uckf1 for my att 9020a and now I'm trying kb3. I has some issues with radio dumps and signal loss so now I'm trying options to see if it minimizes it.
[Nexus S Android Development] Yusei:
Plz someone give me a hand.

My network is terrible

I just added the hspda tweak but now when I enable 3g i don't have any cell service. It says my network (Tmobile) is unavailable. So problem is I'm getting HSDPA except I can't use it. When I enable 2G i get service back. Anyway around this to get 3G working at least?. I have KB3 radio. I'm running latest oxygen

Which radio is best

How should i find out which RADIO is best for the area i live?

For Example i live in Cyprus.

Is it about country or region (e.Europe)?

Regards,

Dimitris A.
[Nexus S Android Development] rrohanjs:
similar question .. how do i know which radio is the best for my region .. INDIA
[Nexus S Android Development] caliban2:
that's fine. hsdpa is just an extension for data of umts (3g). do a speedtest, it will show you what you're on. umts can do 384 kbit/s max on data (download), that's 48kb/s. (under laboratory-conditions)

if your speedtest shows higher numbers, it's using hsdpa.

edit:

please. i hope it's clear that signal strength is important. don't expect high-speed when your phone barely gets one bar on reception. ^^
[Nexus S Android Development] Yusei:
Speed test reached almost 800Kb/s

I think that is fine
[Nexus S Android Development] mad_fitter:
The only way to truly know which radio is best for you....is try each and test. Not for 5 minutes either. Network speeds depend on many variables (peak or off peak time, weather, geographical location, distance from tower, etc...).

I suggest flash one, do a few speed tests at random times of the day. Unless its absolutely terrible, use it for a day or 2. You'll have to play around for a while. Sometimes you can try 2 or even 3 different ones and see no little or no difference.

Oh, also in settings>about phone>status you can see your connection type and signal strength (umts, hsupa, hsdpa) ;)

[Nexus S Android Development] caliban2:
if you're really talking about bytes and not bits, that's not fine - that's outstandingly good!!! Oo :D
[Nexus S Android Development] Yusei:
And in the second and third test I'm getting 1mb/s
[Nexus S Android Development] caliban2:
huh? is that a nexus s 4g or are you running your tests via wifi? and do you know the difference between bit and byte?

you see, the normal nexus s (3g) has a max rate of 7.2 mbit. if you're getting 1 megabyte, that would mean 8 megabit. not possible... ^^
[Nexus S Android Development] Yusei:
That's strange

I note that Stuff, but actually I'm getting those values.

And after hsdpa tweak I'm getting 2000 kbytes/s
[Nexus S Android Development] caliban2:
2 mbit then.

otherwise (mbyte) it would be 16 mbit - technically not possible via 3g.
[Nexus S Android Development] Yusei:
3g can get 7.2 mb/s.

And I'm getting 2mb/s, my net plan gives me permission to get the max net speed.

in logic terms, what is the max speed that my phone can reach?

Edit:

dude, you are right, I'm only catch 200 Kb/s.

Sorry, the configuration of speed test by default gives counting by bits
[Nexus S Android Development] window7:
Well, you could just ask him at his kernel thread? He would answer you :D

Next week, I will start compiling data regarding which radio is the best for which area :D To make it easier for you guys :D
[Nexus S Android Development] Yusei:
Thx dude

Jf1 here and the problem persists

Edit:

I'm going crazy with this, now my network is good, about 600 Kb/s
[Nexus S Android Development] caliban2:
yeah, it's 7.2 mbit max.

but depends on radio, rom, reception, how many people are using the same station as you and if he station itself is capable of 7.2 or 3.6 mbit. in my country, a few years ago when 3g rolled out, you could even have a station capable of 7.2, but the station itself had a 2mbit-line. ^^

so keep testing radios and find the best combination. funny that those 3g-fixes worked for you - i just removed them today and doubled my speed. :D
[Nexus S Android Development] Yusei:
Weird, now, with tweak out without it, it's the same thing.

Around 600 Kb/s

And the H appear and gone, appear and gone.
[Nexus S Android Development] caliban2:
switching to hsdpa (and thus showing h on phone) only when data is really transferred is how it's defined in the standard. some providers "break" that standard and always show the h - pure cosmetics just for you. how often the symbol gets refreshed actually depends on phone-settings.

but this is getting way off-topic. you're using hsdpa. everything else depends on a combination of your radio, your location, your rom (that includes tweaks in build.prop) and your provider. (notice the many "your")
[Nexus S Android Development] ssenbonzakura:
Reposting this if anyone has a solution:

I just added the hspda tweak but now when I enable 3g i don't have any cell service. It says my network (Tmobile) is unavailable although network status shows hspda. When I enable 2G i get service back, but status is Edge. Anyway around this to get 3G working at least?. I have KB3 radio. Running nexus mv latest.

Edit: Figured it out, my signal wasn't good enough for hspda
[Nexus S Android Development] Yusei:
After some hard work my phone have a stable 300kb/s

What are you think about that?

And another thing, can anyone tell me what app i have to use to give some results more corrects?
[Nexus S Android Development] gouthamsn:
I read that KI1 Radio is out ... Any info on it ?
[Nexus S Android Development] ro_explorer:
Doing some testing I decided to re-flash the XXKF1 radio. With this occasion I said I should try the HSDPA tweak ... well ... check the attachment (bottom 2 tests before tweak, top two after).
[Nexus S Android Development] caliban2:
well, this just means your provider gave you 3.2 mbit at the time and location you did that test. and you were able to optimize your rate, according to your previous results. kudos! nothing more, and nothing less. :)

anyone in australia in this thread... what radio are you running?
[Nexus S Android Development] window7:
I'm :)

[Nexus S Android Development] FloHimself:
@window7

Most of the "flash radio XXXX for better reception" is just imagination:

e.g. the GSM reception may just be weaker, because more clients are connected to the current BTS atm.

That said, the only valid source to choose a radio is the compatibility chart from google:

So maybe this chart should be on OP.
[Nexus S Android Development] wildestpixel:
Any harm in setting

ro.ril.hsdpa.category=28
[Nexus S Android Development] kibmcz:
No harm but you wont get faster than your network provides so set it accordingly.
[Nexus S Android Development] polobunny:
That's only compatibility though. Would you say "X radio is better for download speed" to be wrong?
[Nexus S Android Development] FloHimself:
There are quite too many factors influencing the download speed, so in my humble opinion it's just guessing. There is a chance to measure this statistically, but you would have to develop a fixed procedure everyone would have to use for a testing. "each version of Android has only been thoroughly tested with on specific version of the underlying bootloader and cell radio software": this includes heavy testing by using the phone by someone who has insight into the radio software. Also the fact that there are different radio versions indicate a further development and we could assume to the better if there isn't any bug introduced...
[Nexus S Android Development] Rafael Cadina:
I'm running KF1 on my i9020t mobile and I realized recently that switching between 3g to calls takes long. So, whenever I try to make a call and data is on, the call drops instantly even before the call completes. I wonder if it's something related to the radio I'm using. Can you guys show me a light on that?
[Nexus S Android Development] NeoWave:
i have the kd1 on tmobile, i have better speed than with the kf1. and no call problem
[Nexus S Android Development] Ok_Kaleidoscope5109:
exactly. you have to measure this statistically like 10x over or something. everytime you flash a radio you need to reboot. So sometims it takes longer than other times to obtain HSDPA. What if you're stuck on UMTS? Is your test valid? Is the reason why you didn't obtain HSDPA at the same rate as another radio because of the radio or because after you rebooted you gave up your slot on your network's tower and it was overloaded with a bunch of people trying to connect? Then as you rebooted you got kicked back in line and only obtained say UMTS or EDGE?

The point is I would say almost all these radios perform almost the same for downloads. As much as people differentiate about KB3, KD1, KF1, I've tried all 3 and honestly my speedtest maxes out at 4mbps or so on AT&T in the US. I don't think any one particular radio is faster than the other and if so it's marginal, and really unnoticeable unless I had seriously controlled testing.

As for other things that are MORE noticeable, the KD1 radio has the search button bug for me. I asked multiple times here but it seems either I've got a screwed up phone or people are more concerned with placebo effect speed boosts on this thread than anything else.
[Nexus S Android Development] 3rdcoast:
Perhaps. But what I do know for sure is that Upstream speed differences are very real for me and not a placebo effect or because I just rebooted. Being on Rogers I have similar tech as AT&T. However I'm doing tests on a new HSDPA tower that is about 50 metres away (or in American measurement, I could throw a rock and hit it). Oddly enough, I max out at the same ~4Mbs downstream with all UCxxx radios and others newer than KD1 (and no search bug). However on KD1 I can max out at 6Mbs. The big difference is the upstream and latency. max at 400kbs sucks when I can get 3mbs with KD1 which allows me more downstream with less latency.

I planned on not rooting or flashing for as long as I could with the Nexus but within days I had to because of the search bug which was intolerable. Not a hint of that bug since then. These new radios have yet to give me performance even close to KD1. For me, on my phone, with my network at least that is the fact and not a delusional experience.
[Nexus S Android Development] bdpyo:
hey guys, how are you?

thankfully i havent had to venture into this thread nor really have had the need too, but I believe I am having a radio issue of some sort and wanted to come in here for help on finding out what I need to do to get my phone back to normal.

so I typically run CM7 and oxygen with franco kernals. Latest oxygen ROM presented some radio dumps but everything was fine, just more then normal, noticed terrible call quality today, flashed a new ICS ROM and then tried a stock deoxed ROM.

now here is what my radio reads as "Baseband version; NO DGSXXKD1"

I never saw that before and I can post a screen shot if you guys want.

now I'm using my i9020A on at&t obviouisly and I live in the north east section of the USA.

so the help I ask, is that radio OK and if not, what would you reccomend, before I flash to stock, I have OCD and it's driving me nuts! lol
[Nexus S Android Development] some_random:
doing some more testing at the moment... but does anyone think that some radios cause more battery drain... kb3 for me has good reception certainly better than kd1 around my house but kd1 doesn't seem to drain my battery as much, obviously same rom same kernel just wondering if that could be possible
[Nexus S Android Development] stuff:
I just flashed KF1, and my radio won't turn on. It's got the no signal/service, and won't pick anything up. I wiped,flashed over numerous Radios, and still wont work.

any ideas?
[Nexus S Android Development] got2best:
Do u have a back up if your efs partition?
[Nexus S Android Development] Ok_Kaleidoscope5109:
Pshhh don't you love our simpler measurement system? :D :D :D

UC radios aren't comparable to the XX radios. The UCK radios have a cap on upstream. I wouldn't really recommend the UCK radios unless your 9020a is suffering. I've tested KB2 (capped), KB3, KD1, and UCKF1 (capped). All get similar reception and downloads too. The capped ones just have limited upload.

But what I'm saying is for the 9020T, I've seen almost the same performance since KB1 all the way to KF1... I tend to think people who claim exponential gains are full of it. But I can't be 100% sure either.

BTW so you do get the search bug on KD1??
[Nexus S Android Development] stuff:
I believe I do. If so what do I do?

Just restore it.. I believe u can just copy it to the dirrectory.. but read this first and use the program..

---------- Post added at 09:17 AM ---------- Previous post was at 09:16 AM ----------

The XX radios show what you see and it isn't a problem if it works properly. Does it? Then no problem.
[Nexus S Android Development] HeavenlyWinds:
I don't want to seem stupid or anything. But i seriously dont want to brick my phone. These work fine with ICS Roms right?

Edit:

I Obviously need to start searching and reading before asking.
[Nexus S Android Development] Ok_Kaleidoscope5109:
Well I'm not saying there aren't differences in UCK and XX radios. There are, but in progressing along the UCK line and the XX radios... basically saying the radio progression for the 9020T versus 9020A, there honestly aren't that much changes.

When I call BS on people saying that going from KB3 to KF1 gave them 10x speed boosts, that's a load of crap. Now if you compare KB3 vs UCKF1, then that's no longer an apples to apples comparison. You're comparing a capped radio versus non capped.

It's kinda like people claiming ROMs are unstable when they probably:

1) OCed

2) Use some other kernel

3) Have a lot of apps that can be buggy too

4) Don't do a full wipe

5) So many other variables

Thanks for the info, and also this disclaimer should be embedded in every post of this thread =)
[Nexus S Android Development] Ok_Kaleidoscope5109:
It is known the UCK radios have upload caps but download-wise they should be the same.

I've thoroughly tested XXKB3, XXKD1, UCKF1, UCKB2 and honestly the downloads are all about the same.

The reason some people might see big changes are because sometimes radios first acquire UMTS instead of HSDPA and stay on UMTS. You have to e careful when testing. It might not mean the radio's worse, but just sometimes the nature of the signal hunting on the radio.
