I have very weak cell service at my house, and even crappier DSL. Im going to get a 3G/wifi router and an antenna/amp, would like to determine what 3G spectrum is in use at my location. I can use the antenna app to determine which direction to the local tower is but dont know what 3G band is in use.
How can I get this info from my phone?

Is there any way I can somehow get better 3g service and/or voice coverage cheaply. I've been looking at these on amazon, and I don't know what works best with the tilt. Does anyone have any recommendations?? Any tips or anything of that sort??
The best way is to move near the 3G towers. I wouldn't waste my money on the boosters. If you don't already have a 3G signal to boost then you won't get it with the booster either.
you can now buy 3G wireless modems that connect through your phone line to provide a local 3G signal

I already get 2 bars with 3g but the 3g will switch to edge a lot. I'm not moving for cellphone service, I'm only 15!
I was wondering why someone would want to be connected to 3G all the time for talking. I could only guess that it is somewhat better quality. In my case I don't see it that much. I do however know that it waistes about double the battery using 3G all the time. If I am not using data is there any real advantages of it? and what if I am talking to someone who does not have a 3G phone.
Thank you,
Hmm, of course I could be wrong (but I doubt it), Data and voice are 2 different things. 3G is data, voice is voice.
Thats what I was thinking, but I dont understand why it would be connected via 3G all the time if im not even using the data. and 3G and EDGE connections seems to have different signal strengths. If it's only for data I guess I will leave 3G off all the time.
3G signal is emitted on a different frequency than GSM/Edge signal - it does drain the battery faster and is pretty useless if you are in a well covered GSM area and only using voice (phone) function. The quality gain isn't significant enough overall to make it worth battery drainage on a device like the Kaiser/Tilt.
The advantage of 3G is its data stream but it's also good with voice for hard to reach areas only reached by 3G signals - those are rare nowadays, especially in the US, but in some cities with landscape blocked coverage (like in some skyscrapers in Manhattan for example) you might not pick any GSM network at your work desk but might pick up 3G - in such places, using "bandswitch" regularly makes sense.
Lastly, 3G signal is slowly replacing GSM/CDMA (2G) as the broadcasting standard so I wouldn't be surprised that in the next 5 years, more and more GSM phone operators will stop mantaining there GSM frequency towers in favor of 3G.
Thanks jonas that's the answer I was looking for. I will use edge untill my signal gets low.

Interesting, since that means AT&T has a lot of work ahead of them and better get their butts in gear rolling out 3G. I live in the whatever-it-is, 90%, of the network area that does NOT have 3G.
Or I suppose I could be an optimist about what you say, and think that maybe it means AT&T really will be accelerating the rollout of 3G. That would be nice given the snail's pace of 3G expansion in the past couple of years.
Over in the UK 3G is the standard 2G is still available but the telecommunications offcom have required all UK operators to offer a minimum of 90% 3G coverage by 2010
I've always heard that Voice on 3G uses less power on standby and when talking, but I might be remembering it wrong.
Data on 3G uses significantly more juice than EDGE does (over double in my experience!) but I don't think you'll see a significant difference without data usage on 3G vs GSM but I could certainly be wrong.
I always have FlexMail and IM+ running, I haven't compared battery usage without them yet.
One big advantage that 3G has over EDGE is you can do voice and data at the same time. I've heard varying stories about some phones can do it on EDGE and some can't, but I know on my Tilt my connections die when I'm on a voice call and reconnect after but does not on 3G.
The biggest advantage of 3g besides the penetration is that you can talk and maintain a data connection. Edge gives you one or the other at a time--data or talk.
is there an app that can automatically switch you from 2g to 3g and vice versa based on your locale? i know there is an app called "locale" that does location based stuff but it doesnt have any settings for 2g-3g, onyl for bluetooth and wifi.
at home, i would rather just use 2g for voice and wifi for data, dont need 3g at home. but when i leave the house i dont get wifi for data so it would be better to switch to 3g when out.
thanks if there's an app or setting to do this!
Just a +1 to kick this thread and demonstrate some interest in the subject!
My network (Orange / T-Mobile in the UK) has a serious problem with some of its 3G cells —*three of the ones nearest my home have frequent data drop-outs and wildly varying signal strength to the point that calls often drop. The network have been telling me for a year that they know about it.
So, I'd like to be able to switch to 2G either at a known location, or when connected to certain known cells — or even, with a clever app, to be able to force 2G whenever 3G signal quality is varying beyond a certain threshold...
So we just got 3G here this week, but when I am on the 3g network, my cell triangulation doesn't work. can someone with 3G in their city confirm that it is working for them so I can stop worrying about it?
Thx
NC?
How does one know if triangulation is working exactly, ha

make sure your GPS is off then open Google Maps and hit menu - My Location.
I go to lunch in a few and will test. Raleigh NC just turned 3G this week as well.
Confirmed: same issue... can not find my location, where edge can (did not cut off 3g, basing that off of 1 year of using maps up till this week when i got 3g in my city).
Anyone have thoughts on this?
For that matter.... why do i not have 3g in buildings/homes? I only have 3g when outside.
Worked on edge.
In phone status it shows my network as UTMS, not 3G (used to say Edge).
I guess this in normal?
Think about how "triangulation" works (improper name, really):
Along one of the low-bandwidth data channels (along with network time, network name, etc.) are a few small numbers: your MCC and MNC (describe which network: 310/410 for att usa, 310/260 for tmo usa. Those are compared against the return from AT+COPS (or actually a little database if you see "T-Mobile" or "AT&T", compared with "Voicestream Wire", "Cingular", "ATT0", or often just "") to get your network.
Those are then combined with two more numbers, the LAC and CID. The Location Area Code is unique to a region on a network (pretty wide range), and the CID is unique per tower. There is no lookup (similar to COPS) that provides a location from a given cid. This means that you have to look up the LAC/CID against a database (MCC/MNC sometimes speed up searching/possibly sort out duplicates - idk). There are a few of these databases available - there's one free one which I'm thinking about, google probably keeps one (they keep a wifi database too), microsoft probably keeps one, etc. AFAIK, there's no unified database... please correct me if I'm wrong. However, the networks do provide their tower lists to big-name lists.
One last thing to think about - the companies will always try to sell you on the idea that they use multiple towers and find the area their coverage overlaps, or that they use "the unique footprint of a tower"... basically, they put your rough location as the complete coverage area of the tower to which you are currently registered. Actually, they don't really calculate it well - it's just a circle around the tower. What google means by this second claim (the footprints one) is that some of the circles are different sizes, depending on whether the cell is full power, low power, etc. This is especially provable in my bedroom - I have access at full signal to two 3g towers (I love this area ), that seem to overlap right here. This means that, when I use google maps, or another similar program, the circles constantly move between the two. It also means that I get spammed with unsolicited +CREG's on my modem line, as it moves around .
Combining all this knowledge, I know exactly what's wrong. #1: the lac/cid on the EDGE tower elements is different than the 3g towers (makes sense, for signal range calculations), #2: google knows about the LAC/CID on the EDGE towers, and #3: google doesn't yet have the new 3g towers' LAC/CID information in their database. Therefore, the program is passed information it doesn't know about, so it simply returns an error.
Proposed solution: wait a week or two
ADDITION: You don't have 3g in houses because the 3g signal does not penetrate as well (It's on a higher frequency, and the signal drops after less interference than edge). Since these are new towers, they may also be running at reduced power.
I'm in SLC as well, and can also confirm wierdness with the non-GPS location over the first couple of weeks... including one day where my phone absolutely insisted that I was just outside of San Diego. Quite mean of my phone to tease me like that considering that I was in West Valley City at the time. It seems to be getting better as time goes on.
^^ wow, I can feel the authority. Thanks for a great post. I think you are correct, the 3G seems to be getting better coverage (sometimes getting it in my house now). I trust t-mo and google, thank you man.
I don't know EDGE technology (never delved into it), but I seriously doubt poly's claim that it uses a different frequency than 3G. If you're using a USA spec G1, then your tphone has a single radio for t-mobile's 1900 MHz band.
The issues you are noticing with 3G coverage are more likely due to SIR parameter set by the deployment engineers (i.e. they are telling the 3G cell to only 'talk' to your phone if the signal is strong).
This is just a guess, though. There could be any number of issues going on, like some misconfigured settings on the RNC's for your sector (which makes sense if the coverage is new).
UMTS is the 3G technology that T-mobile (and AT&T) use, so that is normal.

yeah, it's generally not too much of an issue - all the frequncies are pretty close (I think the 850mhz stuff from att might go a bit better than the old 1900, but it is pretty close). And, as I just discovered, tmo is entirely 1900mhz, so that part was mistaken. The rest should be accurate to the best of my knowledge (eg. EDGE can take more interference before it drops, etc.)
EDIT: Nope, their entire EDGE network is 1900mhz, but their 3g is only 1700/2100. So, it's a tossup, and that close makes not much of a difference.
I can't seem to figure out why sometimes I get a G connection vs a 3G connection based on the radio icon in the notification bar. Does anyone know what the difference is? G seems to be much slower then 3G.
G stands for GPRS which is a 2G connection and doesn't use the 1700MHz spectrum like 3G (HSPA) does. There are several reasons why your phone would switch between GPRS and 3G. Signal strength and 3G coverage area is limited in the US for TMO is the most common. Certain types of electronic equipment can interfere with 3G as well.
Thanks for the info, I wasn't aware of GPRS. Typically I get E (EDGE) or 3G but inside my office I get GPRS, chances are it's the equiptment. Explains why my connection is so slow inside.
