i have a p6800 mogul/ titan with qwest service and a 100 mb per month data plan (the biggest plan they have). for some reason the towers are recording double the useage that my phone does, compared with spb gprs monitor. can anyone give me any suggestions on why this would be happening or a more accurate monitor or any other ideas or is anyone else encountering this same problem. any help would be greatly appreciated at $1.00 a mb over it is getting pretty costly.
2G vs. 3G
2G Advantage:
• way better battery life
3G Advantage:
• faster data connection
This is a subjective question> Is it worth it at the expense of increased battery consumption?
I have an HTC Diamond with a small 900 mAh battery. So for me, I mostly put mine into 2G and switch to 3G when I use my data connection.
Question: is 2G = 3G when it comes to voice quality? (I can't tell the difference)
...and are there any other 3G advantages that I have missed?
Technically 3G is used for voice as well, but whether you're on GPRS/EDGE/3G I don't think there's a noticeable difference. As for if 3G is worth it? Without question. I'm a huuuuge fan of Android, and I'm dying to get a phone that works with AT&T 3G... Obviously I was greatly disappointed when the Agora Pro was delayed. The G1 seems like the perfect phone for me in every way (except maybe build quality), GPS, WiFi, capacitive screen... But I refuse to buy any phone that doesn't give me 3G, EDGE is painful when you're used to HSPA.
"• can make/receive a call/txt while connected to the Internet (never miss a call)"
thats not a 3g thing thats a cell-phone operator equipment thing
i never lost a call because of grps
thats the real reason that grps was invented to replace
old cell-phone data traffic where you had to call the isp to get
Internet
I don't think it's the right question to ask.
besides the fact that it's individual, 3G and 2G are completely different.
2G provides the regular services which you don't need anything more for.
3G provides services which 2G does not and you will use only if you need them.
so the question is "what do you need?"
I have a polaris on 2G ALL the time... unless I want to connect to the internet.
(just a for instance)
btw, 3G is WAY "less healthy"
for instance, in israel, 2G broadcasts make your phone cast 0.042mW/kb
3G makes it cast 0.43mW/kb. it's like swimming in an ocean of endless EM waves.
that's of course, for an average phone, for full signal

Yeah well, 3G is a data transfer speed. If you're not using data, there's no reason to have 3G.
Ok, then should the question be.........
E vs. 3G.....regarding call quality & battery consumption
Is there a difference?
or
What radio mode will consume the least amount of battery, Edge or 3G?
Edge consumes a lot less battery than 3G.
Call quality is the same....
Ok, so I will stick with Edge as my basis and switch when I need to use my data connection.
you don't need Edge either for calls. call quality doesn't change from 2G to Edge to 3G to 10G. voice is sampled in 44kHz at best. let's say 22kHz. 22kHz is nothing compared to what 2G can transfer. even if you use Shannon's formula you still get a very high value for 2G data transfer. Edge isn't better than 2G unless you want faster data transfer rate... edge can transfer up to 237kbps per 4 time slots. you need no more than 48kbps.
btw.. just as a general remark. human speech moves between... 20hz to about 3khz. 22khz/48khz is required to transfer music through your phone.

Both 2(.5/.75)G and 3G uses GSM encoding (with a very low sampling frequency); that is, the audio quality is exactly the same with the two.

This is particularly true when actively transferring data, and (to a much lesser degree) when just using the phone. I've measured huge (~50%) differences on contemporary handsets - see my dedicated articles if interested.

Do you have any links on this? This is quite big a difference and I'd say, at least under "normal" circumstances, the difference shouldn't be that big.
As CDMA is somewhat more battery-friendly than TDMA (it can transfer the same info using less power), the difference is mostly because of the difference between the carrier (850/900 MHz vs. 1700+ MHz; the higher the freuency, the more power you require to traverse the same distance with the same SNR). That is, with a GSM operator operating at much higher frequencies than 900 MHz, there shouldn't be much difference.
(And, of course, a lot of other factors should also be considered: does the operator use the same radio turn to put all their aerials on etc. If, for some reason, you have a far better 3G SNR than GSM SNR, then, your handheld should use much lower transfer power.)
This is a matter of choices
Each one of us will pick a phone (and a band and a carrier) based on our own needs
In my personal usage, I need FAST INTERNET, so I chose 3G (HSDPA)
I also chose the Xperia X1 because it has a BIG battery
Now I have 3G SPEED and 1.5 days battery life with heavy usage

That's great to hear. Well to conserve power, my choice will be to disable 3G using Communication Manager. When I do this, the 3G icon in the task bar switches to E.
Will switch to 3G only when I need to use the internet.
Perfect ! Thanks for helping me with this everyone

first of all, let me correct my mistake. it's not 0.43 for 3G it's 0.23mW/kb. but that's still VERY high.
I'll try to look it up as i got this info from a friend who worked in orange. but this obviously depends on many factors other than your device. the more relays you have spread around your area, the less power your phone needs to retrieve a normal signal. they're not ALL arranged according to the hexagon method... or the Threeway method.
I'm talking about average power. the closer you are to the relay, the less power you need, but your brain is fried from the relay itself so you can't really run away from it.
FORTUNATELY, power dissipates by 1/r^2 so if you're about 60-70cm away from your phone the effect will be extremely minimal.
"Yeah well, 3G is a data transfer speed. If you're not using data, there's no reason to have 3G."
here we can also use it for video calls directly to another phone number as in not real internet
but nobody use it i think
maybe the problem is that females will spend ½hour freshning up before answering their phones jk
video calls are only different by requiring faster data transfer and much higher signal to noise ratio.. which 3G provides. again, it's not a consideratoin whether to use 3G or not. only if you need to use a video call should you switch to 3G
2G vs 3G......What about (Edge vs 3G)
Wow, some good feedback has been generated here.
Phone use:
• 3G.......is NOT worth it here unless you are video calling
Data Connection:
• 3G.......is worth it here (way faster) even though battery consumption increases nicely
Before concluding with the above, would like to clear up what Edge is:
EDGE can be considered a 3G radio technology and is part of ITU's 3G definition,[1] but is most frequently referred to as 2.75G
Based on the definition here, does anyone believe that using Edge is best when using the phone for the sake of decreasing battery consumption? I believe it should be. Any thoughts?
Actually, EDGE can't be considered as 3G techwise.. and it doesn't have the same data transfer rate as 3G provided by an HSDPA connection.
this is from wikipedia
High-Speed Downlink Packet Access (HSDPA) is a 3G (third generation) mobile telephony communications protocol in the High-Speed Packet Access (HSPA) family, which allows networks based on Universal Mobile Telecommunications System (UMTS) to have higher data transfer speeds and capacity. Current HSDPA deployments support down-link speeds of 1.8, 3.6, 7.2 and 14.4 Mbit/s. Further speed increases are available with HSPA+, which provides speeds of up to 42 Mbit/s downlink.[1]
EDGE only gets to 430kbps AT BEST. the AT BEST part NEVER comes
it's true that EDGE consumes less battery
and it's true that 3G is much faster
but it's also true that this all depends on your needs.
Orange Israel doesn't support EDGE. if they did i would be using it all the time instead of 3G when i need an internet connection.. since i don't need 1.8Mbps..
eventually, i believe there's no debate about what to use.
2G is the best way to go when you do everything but using the internet and video calls.
and then choosing between EDGE and 3G(HSDPA, UMTS.. or whatever you wanna call it) depends on how fast you want your internet connection to be while considering that EDGE consumes MUCH MUCH less battery power.
btw, if you asked me, i woldn't think twice whether you should have a 3G phone or not. having 3G support on your phone nowadays costs nothing more than having a reulgar 2G phone.. so having the option whether to use 3G or not is obviously better than not having it.

tehcnically, EDGE (which is a plain TDMA technology, as is GSM) in no way can be compared to 3G technologies, which are all CDMA.
If my carrier has a HSPA+ 42Mb network, and I have a smartphone with a HSPA+ 42Mb radio and my speed is around 25-30 Mb for example, that means that any other smartphone with a 21, 14.4 and 7.2 HSPA radio should be surfing at their top (theoretical) speed?
HSPA an HSPA+ have inherent problems. If you are getting anywhere near 8Mbps please post a screenshot. More likely that you get between 2-6 Mbps with 170-300 latency or ping and your indoor coverage is worse. This is due to 2 reasons. One, HSPA+ is only 3G with a bit more bandwidth and two, the frequency is 1800mhz or greater which means even a simple window can worsen signal strength.
HSPA+ is not an independent technology, but is a licensed technology making it limited by regulations. Many carriers are using it until their LTE matures. LTE operates at up to 10X the speed, allows double the cells using data, half the cost to the carrier, and a latency around 100 for more responsive sessions. The major players in LTE right now is Seimens out of Germany and Lucent ehre in the states. Their test dummy is Verizon who has 64% of the wold wide LTE market and this is being passed onto Vodofone, an others. In the states ATT has now contracted Seimens and a lesser known company who supplies the core equipment to develop their network. Right now ATT stands at 7% of the world market in LTE.

Very good words, very informative, I really apreciate it. But I was looking for some light about what I asked.
As You can see in my signature I got 6.67Mbps with a ping of 121, and my phone was on 3G not even on H(HSDPA), and this video shows high speed with the Huawe E372(not in my country, I just found it on youtube).
http://www.youtube.com/watch?v=1PUawx4Au_8&feature=related
here in Dominican republic Orange dominicana had a 14.4Mbps HSDPA network, and now they claim they have a 42Mbps HSPA+ network working in Santo domingo and Santiago and coming soon in other areas.
So, my question is, if I get speeds over 21Mbps, let say between 25-30Mbps, that would mean I will get the top speed in devices with a 21, 14.4 and 7.2 Mbps radios? or I could get 25Mbps with devices with a 42Mbps HSPA+ radio (Huawei E372, for example), and get less than 14.4Mbps in devices with a 14.4Mbps radio, etc?
note: I tried to use the youtube feature but didn't work.
A little tougher to answer based on the specific set up in your country. I only gave a background as example or foo for thought regarding HSPA+. I would venture to guess that you could potentially hit that 25Mbps mark depending on traffic, network conditions, interference, and base equipment. If you are within 2 km of a tower and not in a null sector of the broadcast with no interference it would be possible but mostly at burst speed an not sustained. Let me know what develops, PM me with your speeds when you can test it.
I think I might have been permanently throttled on my 4g speeds. I was getting 15-18mbps in speedtest.net for the last couple weeks and I've used 12GB of bandwidth on my last monthly statement with my unlimited data plan. Starting Monday I have not been able to get anything above 4mbps. My month plan reset so my bandwidth usage is back to below 1GB but still not getting above 4mbps.
I'm not sure if I am permanently throttled or if something else on the phone went wonky and is preventing me from getting the 15-18mbps speeds again. Is there a way to check if throttled or to check phone to make sure the settings are correct?

Verizon cannot throttle 4G. It is part of their acquisition of the Spectrum C block they won.
I noticed that Play Music was using a large amount of data. In about a week it used up just under 2 gb of data. I would say total stream time was only around 3 hours. I do have unlimited data with my t-mobile plan so I'm not too worried unless I get throttled after 5 gb or something. I was just wondering if anyone else had the same experience. I know you can regulate the quality to reduce data usage, but I still don't think high quality should use up that much.
Do you have the "highest quality" option chosen, that will increase your data usage. If you are streaming 3 hours worth of music that was not on your phone assuming that a song was around 2.5-3mb it seems possible. It also could've been downloading album art.
This is my biggest complaint with Google Music. It uses too much data regardless of whether I change the streaming bandwidth. It consistently uses more data than Spotify even on the lowest quality. I never had to worry about this when I was on Sprint but I have since switched to Straight Talk and don't want to be throttled either.
Google needs to fix this issue. It's the biggest issue keeping me from switching.

lol, seriously? how many mb is each song that you are listening? and then you chose high quality. 2gb is very normal. throw in a little more into your data plan and you can have completely unlimited high speed data, without throttling. its not an issue here, i have the completely unlimited high speed data with tmo, no throttling. now data usage isnt a factor, and i completely enjoy my device because of it.

its not an issue. google does not assume that you have data limiting you. to fix the issue, get a plan with more data.

I do have the completely unlimited plan, but I heard that apparently you still start to get throttled after 5 gbs. Maybe not to 2G, but just a bit slower. Could be true could not, since you haven't experienced it. I did think about the size of each song, but I thought since streaming is different from actually downloading it, it wouldn't have to use up 3 mbs or whatever the size is per song. I know Pandora doesn't use nearly as much. Also, I think it might be because I skip songs often. So Play music loads up the song before I skip to the next one.

all tmobile data plans are "unlimited", meaning a certain amount if high speed data then being throttled to edge data speeds. well, all plans but one, and it has completely unlimited high speed data($70 everything completely unlimited). i use on average 25-45gb a month, some use much more.
i spend a day or two of my week listening to music, usually either using google play or pandora. i easily use on average between 1.5-2.5gb with google play music after 2-4 hours, and about the same with pandora, on high quality both. also, in play music settings, there is an option to cache music you stream(until you empty the cache). you might have that enabled. itll download and save to your device this way also(as opposed to saving to device).

Gotcha, yeah I know how it works. I do have the $70 one. Well, I have a family plan, but I pay the $20 extra for the true unlimited that now comes with the 2.5 gbs of tethering. That's good to know that they don't throttle. 45 gbs is pretty insane haha.

its a lot, yea. but not that much that use 100+ of gigabytes, lol. it is my only internet access,plus i use the device much. and updating 2gb size apps often! i believe the usage number that they used to post on their website(before their recent site change) if you had the completely unlimited was like 99XXgb allowed. anyways, the plan is for completely unlimited high speed data, completely unlimited is a lot more than 25-45gb
If I did that the At&t police in their orange and blue uniforms would find me.
