Is there a way to change the 3G Frequencies on the G1 to support AT&T 3G network?
Nope, thats a hardware issue.
I thought it was possibly a software issue. If not, is there a way to change out the chip or the incompatable part to make it compatible?

Nope...not going to work for many reasons.
been answered plenty plenty of times.
From what I can figure a hardware change may not be required with the correct radio but we dont know the right radio without the right hardware. lol I know that makes no sense but it makes as much sense as anyone can make of it thus far. When its possible I assure you I will be among the first to do it. Although Im not ready to try installing a new radio without first acquiring a backup phone but if I do Im gonna give it a try and maybe have better luck than the last guy to try.
What about a mini-usb attachment that can receive atnt signals?
I am sure with that and the right software manipulation it could work.

While it sounds great in theory I doubt anyone would put forth the resources for such a limited market.
You would be best off getting android to work on existing AT&T hardware.
in order to do it we would need hardware which would plug in the bottom and software to tell the phone to use the signal from the attachment.
while there wouldnt be millions in the market i guarantee there are hundreds.
if anyone wants to think about it i dont mind making 50 of em and selling for cost. i have some hook ups in the engineering field i work in
ok, my question is... Europe 3g is diff than tmob usa 3g, but is tmob europe the same 3g setup as US? and if europe 3g is same as tmob europe 3g, is att US 3g same as europe 3g. so if tmob europe is same as europe 3g then a europe g1 should work on att US 3g. am i coming thru clear or am i jumping all over?

The American G1 has 3G support for HSDPA 1700 MHz & 2100 MHz, both bands I believe are used by T-Mobile. In Europe I believe they use only 2100 MHz band for 3G.
AT&T on the other hand uses 850 and 1900 MHz HSDPA
The phone has the capability for 2G at 850 and 1900 MHz, so technically it can be used on their network, just not at 3G speeds.
Although technically it's possible to design a Phase-Locked Loop to operate at a variable frequency and to be tuned with jumpers or something, it's probably cheaper for them or they might be subsidized to make phones so that they are exclusive for one network in the US.
To me the ideal is more about standardizing the protocols and the frequencies used for all companies, and having all bands available for traffic. But at least in the short-term that's not really good for business and so probably won't happen for a while.
This is all based entirely on a limited amount of research and my opinion, take it for what it's worth.
Europe uses 1900/2100 in a pair (1900 is the uplink, 2100 is the downlink). (source)
Most phones produced these days are tri or quad band and can work (almost) anywhere.. I'm surprised the G1 isn't.

*sigh*.
Folks, you need to learn about UMTS bands before complaining about that the G1 or any other phone can't do this or that when it certainly can.
The G1 is a 3g worldphone. It works on the US 1700 AWS network (UMTS Band IV) and works on the world's 2100 network (UMTS Band I). ATT uses the 1900 Band (UMTS Band II).
Apparently the common names for these networks is being confused with the actual operating frequencies because they don't upload and download on the same frequencies. The 1900 band is not the same as the 2100 band, even though the 2100 band (UMTS Band I) uploads in the 1900mhz frequency and downloads at the 2100mhz frequency range. The 1900 Band (UMTS Band II) uploads on the upper half of the 1800mhz and downloads on the 1900mhz frequency range. UMTS Band II uploads on the frequencies that UMTS Band I downloads.
These bands separate.
TMO 3g band is different from ATT 3g band which is also different from EU 3g band.
The 1700 band (UMTS band IV) is actually made up of 2 frequency ranges like the other bands I and II are: 1700mhz and 2100mhz. In fact, the 2100mhz download range for UMTS Band IV is within the same frequencies used for the Band I download range, theoretically making it cheaper/easier for manufacturers who make Band I phones to "support" UMTS Band IV phone production.
Most phones produced today are NOT "tri or quad-band" 3g phones. In fact, I have yet to find a quad-band 3g phone. If quad-band 3g phones were made, they would be very likely to support the T-Mobile 3g network, because it's the 4th largest UMTS band type (behind Band I, II, and V). I would be very shocked to find a phone which was 2100/1900/900/850 instead of 2100/1900/1700/850.
And the G1 is a worldphone. It works just fine on UMTS in Europe. It is a band I and band IV device.
read these 2 links:
http://www.htc.com/www/product/g1/specification.html
http://en.wikipedia.org/wiki/UMTS_frequency_bands#UMTS-FDD
So to clarify, when you see a list of support bands, this is what you should interpret from those advertised bands:
2100 Band = UMTS Band I (The entire world outside of North America)
1900 Band = UMTS Band II (The Americas, ATT)
1700 Band = UMTS Band IV (The Americas, TMO)
900 Band = UMTS Band VIII (Australia)
850 Band = UMTS Band V (The Americas, ATT)
Outside of North America, the 2100 band is almost universally deployed, even where the 850,900,1700 or 1900 band is deployed.
I have done some searches and have not found a valid answer to this question. Since the HTC Touch Pro (Rafael), HTC has only put only the UMTS 900 & 2100 3G bands on their unlocked phones. Every phone released since then, has not had the UMTS 850 Band used in North America.
One response HTC purportedly gave was that due to the smaller size of the Touch Pro and the inclusion of GPS, there just wasn't room for more bands. I think this argument is pure BS. The Kaiser had three UMTS bands: 850, 1900, and 2100 and GPS. Making it good for The U.S. and Europe. All the new unlocked devices have 900 and 2100 - for Europe and Asia.
HTC's Touch Pro 2 is also following this disturbing trend having only the 900 and 2100 bands. So European businessmen traveling to the U.S. get no 3G reception on their expensive "top of the line" phone. What's HTC going to say now, there's no enough room in that monster the Touch Pro 2?
Along the sames lines, those in North America cannot buy direct an unlocked 3G phone. They will have to buy their phones directly from AT&T or T-Mobile and get locked into a long term contract to get one.
Everyone on this forum should be upset about this. My guess is that HTC is bowing to pressure from carriers to make the phones unusable on other carriers. This lets the carriers stick it to the customer.
Personally, I'd like to see Quad Band 3G in the phones so they can be used almost anywhere like they could with the Edge networks.
I have my us model sim unlocked, is it compatible with middle eastern bands (mainly Kuwait) and Euro bands (mainly Germany)?

Well, it is if those areas you mentioned use, or mostly use, UMTS band I (2100 Mhz). Now, if they also use, or extensively use, UMTS band VIII (900 Mhz), then I am not sure. Every spec that I have found online has said that the TMOUS version supports UMTS bands I, IV, and VIII; same as other versions. However, the specs on the side of my TMOUS retail box say UMTS bands I, II, and IV; no UMTS band VIII. To make matters worse, the T-Mobile site does not even mention band II at all, just I and IV. So, I wonder where sites such as Pdadb.net, GSMArena.com, etc. get their information, and where can we get accurate information. Sorry that I can't give you a better answer. I wish I had one...lol
Looking at the frequencies of this phone I was a bit concerned we not be able to use it for 4g in the U.K.
What do you guys think?
GSM: 850, 900, 1800, 1900MHz
WCDMA: Bands: 1/2/4/5/8
LTE: Bands: 1/3/4/7/17/38/40
2g (gsm/gprs/edge) should work on any carrier in the uk. 3g (umts/wcdma/3g hspa/4g hspa+) should work on any carrier in the uk. 4g lte will work with only a couple carriers in the uk.
http://en.wikipedia.org/wiki/List_of_LTE_networks#Europe <- you need to check here if your carrier matches the lte bands. it appears that ee and hutchinson will work, but o2, vodafone, and uk broadband may not work.
Only one of Three's bands is covered. The rural 800mhz 4g won't be supported

+1.
Look at the networks that are in your area and compare the frequencies to what the OPO supports.

I'm on Vodafone UK and on their wiki page it says they use band 7 2600 Mhz which the OPO supports, so does that mean inner city 4g should be fine? Just the rural and possibly inside buildings 4g might not be available due to the lack of band 20?
Sent from my GT-I9505 using Tapatalk 4
EE - Band 3/7
Three - Band 3/20
o2 - Band 20
UK Broadband - Band 42/43
Vodafone UK - Band 20
So EE and Three will work on 4G, the others will not, with EE having full compatibility as both their bands are supported
According to Vodafone UK wiki (http://en.wikipedia.org/wiki/Vodafone_UK) it supports band 7 (2600MHz) - so what's the reality with OnePlus One is 4G supported on Vodafone UK or not?

Looks like they've increased their coverage since the initial auction so it should work. I'm on Three so can only comment about them (and 4G does work). Looks like Three are going to use band 20 at some point too so that'll help
apparently 4G band on the OP is compatible with 3
Yes it works currently with 3. I get LTE with 3.

TL;DR at the bottom..
Hello,
So I have had the OnePlus one for just over 3 months now, and I'm currently running 100% stock OxygenOS (even thought that doesn't change the outcome of the question)..
Here in Australia we like to make things so much more confusing than they actually are, and this is truly the case when it comes to mobile phone network names. We currently have 2G, NextG, 3G, "4G" (HSPDA), 4G LTE, 4GX LTE, 4G Plus LTE, 4G+ LTE, and this makes things incredibly confusing when trying to work out if your phone is compatible with a service plan. Currently, I am with "Amaysim", who offered "4G" (HSPDA) plans only, until 3-ish weeks ago when they changed all their plans to 4G. I have already upgraded my line to 4G (free of charge), but Amaysim uses Optus' cell towers. Optus offers 2G, 3G, 4G (HSPDA), 4G LTE and 4G Plus LTE, my phone is working on everything but the latter two (as I don't get the chance to see if they are working till the 1st of May).
Now that we have the backstory out of the way, my question is, will my phone work with the 4G Plus network. From Optus' site:
OPTUS 4G PLUS NETWORK SPECTRUM FREQUENCY COMPATIBILITY
The frequencies we use on our 4G plus network to deliver superfast 4G include LTE 700MHz, LTE 1800MHz, 2100MHz, 2300MHz, and 2600MHz. Depending on your device compatibility, you can access some, or all, of the 4G Plus network. We're using the 700MHz spectrum to expand our network nationally, so If you want to future-proof your device, choose one with the "4G in more places" symbol to access our 4G Plus network wherever it expands. You'll be able to enjoy faster downloads and Internet browsing in loads of new places.
So while I will have LTE as the OnePlus One Supports LTE band 1(2100), 3(1800), 4(1700/2100), 7(2600), 17(700), 38(2600), 40(2300), Optus advertises elsewhere; If your device supports 700MHz/Band 28 – it’s a 4G Plus device.. So while the OnePlus One does support 700mhz, Optus says it's band 28, while on the OPO 700mhz is band 17..
TL;DR: My network advertises that their "4G Plus" is on the 700mhz/band 28 frequency, but the OPO supports 700mhz/band 17 frequency. Is this the same thing, but because of North America to Australia differences or whatever it's different?
I checked the Wikipedia article for the technical specifications of the different bands. Link: http://en.wikipedia.org/wiki/E-UTRA#Frequency_bands_and_channel_bandwidths
Band 28 uses wider spectrum range for transmitting data. Band 17 uplink is from 704 to 716 MHz and downlink is 734 to 746 MHz, whereas band 28 is 703 to 748 and 758 to 803 respectively. Band 28 has wider range of channel bandwidths (3, 5, 10, 15, 20 versus 5, 10). Duplex spacing is also different (30 MHz on Band 17, 55 on Band 28).
In theory my conclusion is that it will not work.

Hmmm alrighty. Cheers, I guess if I decide that I really do need 4G "Plus" that I will unlock band 28 using the band unlocker guide.
Thanks!
