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.
Is there any way to boot WiFi reception on cm7? I love the Rom, but WiFi is a bit sketchy. I'm using the stock radio.
I switch to stock and its way better!
HTC Inspire 4g on Cm7
I've tried multiple radios and multiple ROMs (including stock) but I haven't found much difference in wifi signal strength. In theory, a ROM should not impact signal strength since this is at the radio level. However some ROMs might display bars differently for a given decibel level. Therefore, you should always use decibels (not bars) when comparing wifi strength, using a program like WiFi Scanner or Network Signal Info. ROM A may display an 80 dBm signal as 4 bars, where ROM B displays the same signal as 3 bars.
Is it normal for the Mbps of y connection to go u and down so much? Seems like it wants to drop to 1 MBPS and hang there. This causes my internet browser to be very sluggish. Am I missing something?
I've noticed it also in my anecdotal experience:
At a far end of my house with CM7 and stock radio, I get sketchy Wifi reception (phone flips between wireless and wifi.) Can't surf without disruptions as wifi connection gets dropped and have to wait for the phone to get on 3G.
With stock ROM and stock radio, I can surf without any issues on wifi at the same location.
Theoretically, ROM shouldn't make any diff, but I'm seeing otherwise in practice.
On Synergy 1.7 and imoseyon kernel 0.1.
I play poker for a living in Atlantic City so I spend a lot of time in a hotel room on high floors. Signal is either medium, low or very low depending on the room. I notice a lot that if I make the phone 3g I get 2 to 4 bars, and internet works. When I turn on LTE, signal drops suddenly to 0 or 1 bar, and internet is slower than 3g. A lot of the time it will auto switch to 3g. Anything I can do, and are there any legit apps or hardware to boost signal?

Yeah pay for wifi, you are in a hotel lol. Most likely the hotel (if a big one on the strip) has a signal amplifier for 3G. LTE is probably too new for them to have one installed yet. That's your difference.

$12 to $15 isnt worth speeds slower than 4g. Hell if 3g can do better than 384k speeds then the wifi is slower than 3g. Really wish legit signal boosters exist.

Might just be in a rough area for 4G or because your inside the signal is weaker. Same thing happens to me at work, as soon as i walk inside the signal drops a lot
Rate this thread to express how you think the OnePlus 2's Wifi performs. A higher rating indicates that it has excellent range, throughput, and signal strength. Like when you're taking a dump in the bedroom upstairs, do your videos have to buffer or do they come through without interruption?
Then, drop a comment if you have anything to add!
Coming from previously a Galaxy S4. I have to say OPT WiFi range is excellent as it even gets coverage from previously a blindspot at home
Sent from my ONE A2003 using Tapatalk
Excellent wifi coverage
Multiple wifi zones are covered and speed is consistent across all bands
Wi-Fi strength is ok, but it has 5Ghz Wi-Fi too!
Too bad that my router can't use both Ghz frequency.
Only 1 band ac wifi not dual
Coming from Nexus 4 and OPO I'm very disappointed with OPT wi-fi range. While before in my bed reception was good, now I'm almost always in LTE 'cause wi-fi isn't caught!
Wifi Range and reception is bad compared to Xiaomi phones with Dual band
WiFi on the OPT is amazing, my router is at the front of my house and my bedroom at the very back, most phones can only just pick up a WiFi signal in the bedroom or in my back yard, usually it's better to turn WiFi off because the signal is weak and the speed it slow.
However the OPT holds a stronger signal with no loss in speed

I can only agree! Best Wifi dBm i have seen so far! But 2G and 3G is not that good...
Facebook shows offline
I am on WiFi most of the time. Sometimes Facebook starts showing up like its offline even if connected to WiFi. I have to force close the app and then restart it to work. Not sure if that's a software glitch. Can anyone help?
