i have already modified ro.ril.hsxpa=1 to 2 and ro.ril.gprsclass=10 (CM default) to 12 and have not seen much improvement in the dl/ul speeds.
infact its very similar.
however having seen addtional modifications made by other users ( see below) is it worth adding them to improve dl/ul speeds in the UK/Europe
ro.ril.hsdpa=8
ro.ril.hsupa=5
Can you explain what that does?

ro.ril.hsxpa=1 - HSDPA
ro.ril.hsxpa=2 - HSDPA/HSUPA
the latter is more suited for Europe/UK 3g mobiles whilst the former for the US
not sure what the following do but they helped one user in the " new radio thread" increase his dl/ul
ro.ril.hsdpa=8
ro.ril.hsupa=5
Just make sure you have hsxpa set to 2 if you use ATT or your upload will be capped at 384 kbps. T-mobile users don't seem to get effected by this for some reason.
Well, I'm on T-Mobile UK and adding
ro.ril.hsdpa=8
ro.ril.hsupa=5
makes my phone not connect to HSDPA any more, just GPRS.
thanks tried it as well same result however faster dl/ul on changing the first to properties to 2 and 12
Hi all,
I live in Germany and had a Motorola Milestone 2 before. On my new beloved Droid 3 which I imported and unlocked for usage with Vodafones network I noticed signal issues with both EDGE and 3G. So I searched for a soultion and found a thread about the Droid 2 Global which is said to have a not so well GSM signal too and offers a solution for this.
After adding these lines to my build.prop I have noticed a HUGE improement of signal strengh and data transfer speeds.
Code:
the code is (much thanks goes out to Zeppelinrox and his v6 supercharger script):
ro.ril.hsxpa=3
ro.ril.gprsclass=12
ro.ril.hep=1
ro.ril.enable.dtm=1
ro.ril.hsdpa.category=28
ro.ril.enable.a53=1
ro.ril.enable.3g.prefix=1
ro.ril.htcmaskw1.bitmask=4294967295
ro.ril.htcmaskw1=14449
ro.ril.hsupa.category=9
Please test it and tell me if it works for you too!
This is the original Droid2Global thread: http://www.droidforums.net/forum/dr...acking-tweaking-3g-settings-radio-driver.html
According to the thread you linked it was added to local.prop , not build.prop?
I'm also guessing he meant local.prop
So anyways, added it to the file, rebooted, and everything still works.
It's too soon to say if anything improved at all. Not more bars than before the reboot anyways.
Hi,
yes I know that in THAT case it was added to local.prop, but while looking around I saw that these "tweaks" are pretty old. On a CM page those lines were added to the build.prop so I put them there, too.
PLEASE report if you notice any improvements.
Ok i see. So you were correct after all. I will change it and report back
Edit: Changed it in my build.prop this time, and rebooted, but not much has changed for me.
I'm on the Vodafone network in The Netherlands.
OK, would you say that it would be better to put those lines in the local.prop then?
Nope, i'm saying neither of them are doing anything for me
But i did some searching for the changes you mentioned, and one of the articles said it could take up to 3 reboots before it takes effect.
There was no mention of signal though. Just speed.
Well, I just tested this. And it seems to have resulted in better signal reception. At least for me, so thank you for digging it out!
I tested it too but it doesnt work for me. Maybe it depends on the carrier you´re on. (I use E-Plus)
I tried to edit both Local.prop and Build.prop, I had no problem with editing Build.prop...
but for Local.prop, it resets to default as soon as I reboot my Droid 3, is this the reason why I have not experienced any improvement?
Thanks.
You could also use Network Info II or some sort of signal checker off of market to get a numeric before/after measurement of your cell signal. I'm interested in the results.
@Moderator: Please move this topic to general! Thanks!
i found no difference in the dbm of my signal strength after this, and in all honesty unless you do a large number of speedtests before and after (i'm talking 20), any differences you see will probably be within the margin of error

That's what I figured, too bad
Is anybody else's phone hanging around in 3G even if the singal strenght is ~109db (or no signal bar) and no more mobile internet is possible, but at 2g the signal would be great? It takes just too long to switch and its burning battery like hell meanwhile.
I did notice that too...
I'm on a dext while motorola fixed my hardware keyboard again .. it has the same problem, poor battery life, low 3g signal but no 2g signal at all. Probably related to my provider but i did notice thatwith the last swap phone they gave ne (desire z) it had at least 2 bars better reception and 3-4 times the battery life. Didn't measure the dbm for any hard numbers when i had it. Shame

Are you trying to get 2G signal on Bell Canada? If so - no GSM phone will ever pick signal - Bell does not have 2G network - only 3G.

I have a DZ and my Droid 3 is crossing the Atlantic sea right now, I can compare them easily the next week.
After the poor battery experience with the milestone 1 I decided to keep the DZ, to see if the droid 3 is usable.
I added the code to build.prop and after reboot it remained.
But I didn't noticed an improvement in signal strength. :-(

JamieD81 had a neat little hack for build.prop that he implemented in his Codename Android port that uncapped 3G speeds on the Note, but he never said exactly what it was. I was wondering if anyone knows how to reproduce this? Or is this the same as the "Enable HSDPA + HSUPA" option in AOKP ports?
Is anyone aware of means/method of enabling Simultaneous Voice and Data on 2G and/or 3G?
Scenario::
You receive a call and you are talking on the phone but the same time you want to browse through a couple of websites using browser, or check for new incoming emails, or lookup for some location on Google maps.
I am on 2G Network, Airtel (Maharashtra Goa) based out of India.
I checked a few thread on XDA and found one which talks about this by doing a few tweaks in the Build.Prop file.
Like for example
http://forum.xda-developers.com/showthread.php?t=951765
http://forum.xda-developers.com/showpost.php?p=11329631&postcount=19
This one is for Xperia X10
ro.ril.hep=1
ro.ril.hsxpa=2
ro.ril.enable.dtm=1 (This is the setting for enabling Dual Transfer Mode or simultaneous Voice and Data
ro.ril.gprsclass=12
ro.ril.hsdpa.category=8
ro.ril.enable.a53=1
ro.ril.hsupa.category=5
So I indeed added the below line in my build.prop file and rebooted my Xperia Z1, but no luck.
ro.ril.enable.dtm=1
I haven't done all the settings i displayed above because i am not sure of what class Xperia Z1 is (i think it is Class 32, but i may be wrong).
It must be supported by your carrier too, if your 2G network dosent support dual transfer mode it will not work even if you have 2000$ worth phone.
Appreciate your response.
Ok, I understand. And i did read a few articles saying the same thing.
Strange that Airtel Calcutta has this feature supported (when the initial post was subbmited in the other thread on 13th February 2011) and Airtel Maharashtra does not. By the way, Airtel Calcutta and Airtel Maharashtra are two different cellular circles but in the same country (India) and managed by the same company Airtel.
Anyway, is there a way to check if this feature is supported by my cellular network without having to contact them. I can bet they would not know what this is. I did try to Google this info but was not helpful.
I am looking for a way like an app or a link where we can test if this feature is supported by the Cellular company. Is there a way to test this ourselves?
I know app open signal map, but I don't know will it help you to much.
I think only contacting them is easiest way.
