so many of you have probably enabled your 4g LTE chip on your device but when i try the trick it doesnt work. after research i found that australia uses a different band of LTE to what the nexus can use. a friend of mine suggested that i root and flash a custom radio that works on the australian bands so i can enable LTE. Does anyone know where i could find this radio and/or if it actually exits? and if it does how do i use it?
Hi,
Can't recall where but somewhere it said it only has physical support circuits , I think amplifiers, for one specific band to support LTE. That would mean its not possible without he mod to utilize another band for LTE.
Cheers

There is no LTE chip in the Nexus 4, band 4 AWS LTE (1900 MHz) is natively supported by the processor, and is the only LTE you can connect to. Check and see what frequency and band LTE is in you area, if its any thing other than band 4 AWS 1900 MHz you can't connect to it no matter what you try and do. Google also fixed the LTE exploit in version 4.2.2 so you would have to either roll back to version 4.2.1 or use a ROM that supports LTE, they say so in their description. But again check to see what frequency and band LTE is in your area as that's what will decide for you what you can do.

Does it work on AT&T's LTE network? Anyone?
The phone does not have LTE hardware/radios. So there is no need to try it.
My mistake. I assumed the Euro version was LTE enabled.

Totally agree with pops without the 700 or AWS LTE Bands no way jose!
Hi,
I'm also wondering about LTE here in Canada on Rogers. LTE is on 2100 Mhz here. Has anyone tried entering settings and which network types are available? GSM, WCDMA, etc...?
To help clear up some confusion. There is no currently available Galaxy Note for sale that supports LTE. Here is what the European version supports.
GSM/GPRS
Frequencies 850/900/1800/1900
3G/HSPA
Frequencies 850/900/1900/2100 (Quad-Band)
LTE: No
WiMax: No
The upcoming Korean version may have LTE, but we will need to wait and see.
There are over a dozen bands worldwide approved for LTE. Just because a phone has an LTE radio doesn't mean it will work with a specific carrier. Unless they come up with a universal LTE radio that supports a dozen bands we're all kind of screwed as there won't be any roaming and we'll have to buy phones directly from the carriers. VZW and AT&T both use the 700MHz spectrum but because of slight differences in the frequency their radios are not compatible. LTE's going to be a mess.
My cell provider uses 1800 frequncy for 4G LTE and I read some where that the nexus 4 uses 1700 or something .. So my question is am I able to connect to 4G somehow ? I live in kuwait and my provider is called "zain"

LTE only works in AWS, 1700 I hear it referred to as band 4 on the nexus 4.
I dont think At&t's LTE work on this phone either.
Alright thanks guys

I checked Qualcomm WTR1605L specification and it supports 1800mhz LTE. So why doesn't it work? Software limitation?

Its a hardware limitation as there are no signal amplifiers and filters installed except for band 4 AWS which are included in the chipset. This works basically only on T-Mobile LTE at 1900 MHz in the US. This issue has been discussed to death in this forum and is very old news.

Turns out some AT&T markets use the AWS band for LTE, spectrum problems I hear. So in some markets you may get att lte on this phone.

Fairly certain you meant 1700

So.. correct me if this is wrong; the Nexus4 supports AWS HSPA+ out of the box (aka T-Mobile), but also can be modded to support LTE on the same band- which many other carriers besides T-Mobile use.
This is very rare, isn't it? Because in every other commercially-released device, these two features are pretty much mutually-exclusive. If you buy a phone that supports AWS out of the box from T-Mobile or a Canadian carrier like Mobilicity it has no LTE support because those carriers don't offer it. If you buy a device with LTE support from a larger carrier like AT&T or Telus, it has no support for AWS at lower speeds because its carrier doesn't use them.
So the Nexus4 would be the only device to support both these carriers at maximum network speeds?

All T-Mobile LTE phones support AWS and LTE over 1700/2100mhz.

So got my new baby, and I love the stock Android UI.
But I got issue connecting to LTE networks here in Germany. A friend of mine bought it in the US store and sent it over to Germany. 3G no problem, but LTE isn't working.
I checked the tech specs, and it says 4G LTE (700, 850, AWS, 1900 MHz). Here in Germany T-Mobile is using Band 3 (1800 Mhz) and Band 20 (800 Mhz) So there is the culprit.
Is this a hardware restriction, or could be solved via software? Maybe flashing a different baseband?
Unfortunatly on the Phone Info screen, you cannot change the GSM/UMTS band. The list is empty. It worked on my Nexus 4 though...
Maybe its possible with a modified modem/radio, dunno it thats correct though and how to do it. There is a radio thread on this forum http://forum.xda-developers.com/showthread.php?t=2192025, check it there.
It might be possible to change the bands using QPST (you won't be able to flash the international modem) there is already a thread on the I337 forums http://forum.xda-developers.com/showthread.php?t=2291589 that has a tutorial for enable AWS bands on the device. The process should be roughly similar assuming the device's hardware can operate at those frequencies.
If it works you will lose north American bands until you rehash the I9505G configuration back.

i need the band 4(aws) but the XT1642 just have LTE bands 01/05/07/08/19/20/28
have any way to change or chose the bands? or its hardware
Thanks
I am also wondering about this. Someone please give it a productive thought.
Any ideas on this? I've read about this method http://forum.xda-developers.com/cro...ad-progress-please-leave-im-updating-t2871269 and it should work with the Qualcomm Proccessor of the Moto G4 plus, but I don't know the code to activate the Diag.

There are limitations because of the hardware bits (RF amps) that are missing. For example if the radio works on LTE band 17 (DL 740Mhz, UL 710MHz), then it might be tricked to work in LTE band 12 (DL 737.5MHz, UL 707.5MHz), they are "close enough" to work.
Also I had a Alcatel phone that was sold by T-Mobile with one of the existing bands (LTE 5) de-activated because it was not used by T-Mobile. After unlocking the phone (legally) it would still work poorly on AT&T network - and then I was able to activate that band by using the above software - because the needed RF amps where already present inside.
LTE band 4 AWS is a special animal, the DL and UL frequencies are VERY far apart. Not matching anything else, so even if we can program the radio to work in those bands, the output RF amps will just not be able to perform.

I'd love to say that I understood you but I'm very ignorant about bands and frequencies.
I read that the QC SnapDragon 617 has a X8 LTE Modem (can't link because I'm new, but it's on the QC webpage) which has the Snapdragon Global All Mode, and it's supposed to support band 4 AWS. I don't know if that helps with the output RF amps, or I'm totally doomed.
Yes the X8 Modem supports the bands. But it needs something else to work. Those bits are soldered on the US version and not on the EU one. Similar, on the EU one there is band 20 that is not present on the US hardware.
Hello to all,
I have a ZenFone 2 Laser (ZE500KL). Asus support said me that is a Taiwanese version.
The issue is that is not working with LTE network in my country, only with 2G and 3G. Here is used AWS1 that is the same AWS band 4 (1700/2100 MHz) 1700 for uplink and 2100 for downlink. Asus support said me that I have nothing to do since is a hardware issue because the antenna doesn't work in 1700/2100.
Is there a way to know if this handset could be enabled to work with LTE AWS Band 4?
Thanks in advance for any help.
Regards
First thing first, I'm sorry if my reply did not help you, and this is based on my limited understanding...
Simple answers would be nothing, nothing you can do if this is "hardware" limitation as asus told you.
Now the explanation, note that I'm not knowledgeable about this thing, so I don't think could give a meaningful explanation.
From what I've read, LTE, on different country use different band (1700, 2100, etc). And by that, just say *not the real reason, just play along with it*, "device built by limiting hw capabilities to certain band, to work on region A, because that device didn't meant to work/used outside region A" . This might the reason, you could see asus with WW or TW variant. They limit the device hardware to work only with certain band range.
This is hardware, not software/firmware (if you compare it to like some "unlocked provider device") . So you can't do anything about it.
This is like, using CDMA phone with GSM card, they work at different band. AFAIK it didn't work, cmiiw.
Oh, IIRC, old phone (before Android born) mostly have triband (GSM) you might won't be able to use your device outside your country. Then, newer phone, till now, use quad band to support usability around the globe. cmiiw
I hope you get what I'm trying to say there~
I don't know what it mean about LTE aws 1 / aws 4, I don't think this is just band length (1700/2100).
