Modem with quickest GPS

Hi everyone. I wonder what modem has best performance with GPS like which one is quicker fixing on satellites? Anyone tried?
Sent from my GT-I9100

modem has nothing to do with finding satellites as the gps chip is seperate from the modem.
modem will only assist you by downloading approximate position data.

I still think there are some drivers for gps are located in modem, while using sgs1 I learned that gps lock was better on those modems that were designed for remote areas with only a few towers around. I believe there was a thread on sgs 1 branch about differences in various modems, and one of differences was gps reception. I don't think sgs 2 its much of a difference in that area.

Recently after flushing new ROM I changed to KH3 modem,never dug in it but it seems like GPS improved.

There are different modems KG1 2 3 etc . But where do you get a modem for a remote area and how is it supplied on a factory product . You dont get a modem for USA and one separate for users in the Nevada desert .

[Q] very low signal strength on CM9

i just flashed CM9 last night and now have very low signal strength. Has anyone else experienced this and if so, is there a file for this to download and install?

USB or Radio Strength?

radio strength. also, i can not find anywhere where you can update your sprint PRL and profile. Sometimes that helps as well.

What modem? Are you on a custom kernel? What alpha? What theme/mods?

Like marcusant said, and for as profile/prl you cant . but for modem you can change it through ODIN

Did you check your actual dbm signal strength in about phone? The signal bars don't always read correctly. Have you actually lost signal or dropped calls? I was next to my Airave at -76 dbm which should be full bars and display was only showing 3.

ok, i see Ei22 listed in the baseband version. i assume that is the modem? since i am having a weak reception from that one, can i just switch to any other one on that page you linked to me or do i need to stay with a certain one? are they all compatible?

You can switch the modems to any of them. The modem has nothing to do with the Rom. Different people have different results from the different modems so give them a try and see which works best for you.

There are only 4 signal bars. This makes it seem like less as one bar is almost two with 6 signal bars.

Question in wrong place

I don't know why nobody else is having difficulties with WiFi in the ICS released for the Nordic..it keeps disconnecting and connecting every minute not to mention the weak signal status..it's really bad and annoying..anyone experiencing the same obstacles?I tried re-flashing 3 times but no go..and tried all the possible solutions but nothing..

No problems with Wifi for me. Have you tried on different Routers/gateways?
Maybe you need to reboot your Router/Gateway...

To fix it you have to select a fix channel on your router (not automatic selection).

Modems Review (I9000)

Hi,
I have started this thread as I haven't seen any discussion forum which gives us a review on the modems being used in India.
I have tested quite a lots of modems and here are my reviews on each of them.
1. JW4 - battery life was good, lots of drops in network
2. KB3 - battery was draining like a hell in 3-4 hours almost 60-70%
3. KF1, ZSJPG, JVT- all are balancing the battery life and good network speed
4. BUJP5 - currently testing since yesterday night, amazing network speed and good battery life.
I have tested all the modems being on ICS and using them on 3g almost whole day and remaining being on WiFi.
If anyone of you came across any new modem, please post the link of the same and I will try to use it provide you the review for it (no ETA please)
Location - Mumbai
Network - Vodafone/Reliance

Can you please mention your location and network (in OP) as performance is network and location dependent.
Also if possible can you test with more than one networks ?

You seem to have covered quite a few modems. Thank you for that. I've tried a few myself and am tempted to recommend that you try XXJVU. I've experienced excellent battery backup and network connectivity with it.

Sure i will test this too and will update the op.
Did you tried it on ics as the link you provided is on custom rom 2.3.6
I9000 powered by RemICS-UX

UCKF1 — Signal ranges between -70 dBm to -85 dBm. Battery life good.
DDJV5 — -60 dBm to -80 dBm. Battery life good.
XXJVU — -50 dBm to -80 dBm. Excellent Battery Life. Best modem in my opinion.
XXJVT — Same as XXJVU.
I have noticed the XX series so far has given the best signal reception and battery life.
Please note, if you are using a 3G network in India, signal reception would be average everywhere. And the signal would keep fluctuating between 3G and 2G. Hence, hardly all 5 bars.
The above readings have been done on 2G network mode.
A very important thing:
Most people think the modem is the primary drainer of the battery. It's NOT. You have to use a good kernel too. I have used a variety of kernels on CM9 and have figured out that Semaphore is the best kernel. Devil3 is the next. Stock kernel sucks for battery life.

Just take the note of one which you are using right now by going to settings-> About Phone -> Baseband version.
Whenever you want to go back just flash the appropriate modem version by downloading.

Thanks mate for the above link however I think we are aware of those modems and few of them are not going to work in India and few are from old firmwares.
I am only trying those which are newer as there is no point in testing old firmwares which are already outdated.
Hope this makes sense...

No, I haven't tried XXJVU modem with an ICS rom. When I was using an ICS rom, I went with the default modem that came with it. Never did experiment much with custom rom's.
Edit: Apurv24's post carries the link to it - XXJVU - the 2nd one; appears to be listed under ICS. I'm not sure about the risks and compatibility either.

No prob i will give it a try.
I9000 powered by RemICS-UX

So far I have noticed XXJVU gives the best signal reception almost all over India. I'm from Pune.
I have traveled and used my SGS with ICS and XXJVU all over India(North, East and South) apart from my home town Pune and have got excellent signal reception (-50 dBm to -75 dBm).
Please note that this is over a 2G network of Vodafone. I also have a 3G plan but when I shift to the 3G networks the signal reception starts fluctuating and gives a horrible 1 or 2 bars.
If you are going to use 3G networks in India, you will face issues with signal reception. Most cities in India have horrible 3G connectivity—metros included.
All in all, XXJVU gives me excellent 2G coverage all over India on my SGS i9000 with ICS and Semaphore kernel.
Battery usage is decided by a lot of factors apart from the modem—Kernel plays a major role in battery usage too.

[Guide] Must Read ! Modem & RIL

What is Modem?
Modem/Radio/Baseband is basically a driver which receives and sends Mobile Network signals as well as handling switching between GPRS, 3G, HSDPA etcodem?
Are they firmware specific?
Modems are not firmware specific. You can install any modem for the Galaxy S3 to any firmware, (*** T variants have their own modem version for network compatability),
Why is a good modem important?
If your phone has to constanly search for signals and lock on to them it not only gives you a poor call and data quality but also drains your battery.
Where I can Download different Modems?
You can check it here
What is RIL?
The RIL is a program between the Radio and the ROM. It communicates with the hardware and supplies an interface for the ROM so it can use the hardware.
What does it mean?
Think of it as the device driver you have to install to your PC when you're adding a modem, so that the PC would recognize and work with the modem. In short it acts as a translator between the hardware and your software.
How do check if I have a compatible Modem & RIL on my phone?
There is a certain app on the market called GetRIL, it attempts to match RIL, (Radio Interface Layer), with your modem for a more efficient operation.
What will a modem with matching RIL give me?
Simple.
You will have an even better network connectivity (eg. E, G, 3G, H, H+). For example, I am now consistently getting a H+ connection where previously I would only be getting H at best. This will obviously improve your speeds during browsing, the more chance you have for Fast Dormancy to work as it should, thereby saving battery
Is it Important?
That of course depend you users. If you think its worth a try.
So is it Okay to flash different firmware on different Regions?
That depends on the user.
How do I Check if I have a compatible Modem - RIL on my phone?
There ia an App on the market called GETRIL wherein it checks your modem ril compatability
"Check Attachments Below"
How do i check if I have a good signal?
There is an app on the market Network Signal Pro wherein you can monitor your connection signal for stability
Does modem affect Wifi?
Certainly Not, wifi is controled by a kernel not modem
This should be helpfull to you guys especially those who are flashaholics and newbies
Please Press Thanks

*Reserved*
Should I make this a Wiki?
Is this relevant?
What do you think guys?

Its relevant if RIL makes a difference to the majority .
But as you know the majority probably have the wrong RIL i know i have .
But yes either added to the stickies or the Wiki.
jje

Of course it should be a wiki, I've already done these process and I realized that i was with the wrong RIL
IDK if it's just an impression but my conection seems to be a little faster now
thanks for this guide! :laugh:
Edit: I was also having issues with BBS with the statements "No data connection" and "No or Unknown Signal" with the ration on 100%
I'm checking if this will be solved with this fixing of RIL

Yep certainly does.. I think so too..
Having a compatible Modem RIL really is an advantage compared to flashing without checking Modem-RIL compatablities...
RIL acts as a translator between the hardware and the software ...
So get a smart translator. The one who can translate well. =)

Can anyone make tar modems flashable via odin?

Good guide, maybe add that I9300T modems work fine on I9300 phones and the way around as this question comes up quite often in Q&A as well as the modern collection thread, maybe also link that collection to your guide.

Now lets put matching RIL.... done... reboot... done and, lets re-check speed: the result is exactly same.
So, is the matching RIL a must, or a maybe?

Same for me. A mismatched 9300t modem gives me faster speeds than an LID or LIB modem matched. Matching RIL made no difference to my speed tests.
I doubt it's a must

As stated on my post.
Importance of Modem RIL depends on you users.
Just be reminded that RIL acts as a translator between your modem(hardware) and your software(operating system)
SO if anything is not matched would there be discrepancies?
So we are talking about stable connectivity thus resulting greater improvement on battery and speed on that matter.
H+ is much faster compared to H, 3G, E.
I didn't say its a must so you decide =)

Yes, and you can be surprised, but LTE is even faster, so what?
spending even 30s on matching the RIL, when there is no proof that it is better.

I have personaly tested to many modems and tested speed test and stuff
Try it youll see the difference salud
