Hello,
Can someone tell me where the radio is located in the motherboard, I mean the radio to make and receive calls, 2G, 3G, 4G, LTE.
Is it together with the processor? That rings a bell but I am not sure. Please see attached a couple of photos from the motherboard, front and back, in case you want to use them to point it to me.
Thanks
Found the answer in here:

recently my gsm reception on my artemis goes like this:
nothing,for a few moments a little bit and then again nothing..
so I think that somethings wrong with the internal GSM antenna, I want to open my phone but where is the antenna located and how? can somebody help me with a photo or tutorial?
thx!
Since I was a dumb and bought a Tmo TP2 to use on ATT, I was wondering if I could buy the antenna from the ATT version and swap it into my phone. Though I doubt it is, I was curious if this is feasible?
Since both networks are UTMS, not CDMA, and thus use similar frequencies, why, therefore, would you want to disassemble your phone and mess with the antenna system, which should work perfectly well on both networks?
Frankly, it sounds to me like you have a different problem: Your phone is most likely locked to T-Mobile, meaning that it cannot use the AT&T system.
Your problem is therefore contractual, not technological, in nature.
I think the OP was actually asking if he could switch his radio, since the T-Mobile radio will not get 3G speeds on AT&T's network (discussed quite a bit here; do a search).
The answer is no. Although it may be technically possible, it would not be practical. Far easier to just sell your T-Mobile version and by an AT&T one.
Ok yea I guess its the radio. Thought it would be the antenna. Could you please explain the difference. I guess the antenna is solely reception and the radio is what interprets the signal? Is there a broken down pic where you can point out the radio.
I was hoping I could just get this http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=250525496122&ssPageName=ADME:X:RTQ:US:1123
Radio: The electronic hardware used to convert electromagnetic radiation signal (radio waves) into usable electrical impulses to decipher to either data (ones and zeros) or audio (speech, music, etc). May also use software systems to further enhance or aid the deciphering of the received signal.
Antenna: The hardware (often as simple as a long wire, sometimes as complex as an array of directional beam antennae) used to gather said electromagnetic radiation signal, and direct it to the radio electronics hardware.
Hope that helps
Thank you for your replies.
So Im guessing the radio is either expensive to buy or requires to replace the whole motherboard?
I recently purchased a t7373 with dual cameras only to find out it doesn't work here in the usa. I need an AT&T Tilt 2 motherboard with the Antenna Module for this to work. Does anyone know of or have these items. I would really appreciate this.
If it isn't a US phone, it is probably broadcasting on different frequencies than we use here in the States. Some of the frequencies overlap, but you won't get great coverage and you won't get the full coverage map for your carrier.
Not much you can do about it either. You'd have to physically replace the antenna. Not sure that's even possible, but if it is it will require some serious precision soldering.
Otherwise, you'll just have to replace the whole phone. It'll cost you more to try to replace the mobo than just replacing the phone.
I want to get a carrier for my Note 2 R950, but unfortunately they're a GSM service and the R950 isn't compatible with GSM services. What part(s) would I have to swap to get GSM capabilities? I think I would have to swap the speaker module with a N7100 part (since it contains the CDMA/GSM antenna I think), and a replacement N7100 logic board with a clean ESN (pretty sure I have a bad IMEI, also Sprint doesn't allow other phones onto its network but its own), but maybe I'm wrong. What would I have to replace?

I can't replace the speaker. Just noticed that the R950 layout is different around that area and would require getting a different digitizer assembly entirely (there's simply a screwhead that doesn't fit with any other part) Wondering if I could use Sprint's CDMA without replacing that speaker but just the logic board (as Sprint doesn't allow other phones) or maybe even GSM services?

Actually, I observed the speaker module more and it looks like I could just cut out that conflicting plastic so it'd fit. I'm not sure about the connectors but I believe they fit. After looking at some diagrams, it looks like the speaker module is the primary CDMA/GSM antenna module, so I'd probably have to swap it. I'm trying different SIMs and even though I'm on CyanogenMod it won't change. (which is weird because it stuck to Verizon signal? I'm using an R950 logic board and SIM card atm but it still connects to Verizon) wouldn't make a difference if I'm changing the logic board anyway but it's worth noting.
i have a note 2 n7100 which does not have 4g. if i can get hold of a n7105 board and swap it, would it work?
No it wont work

Thanx for the reply but isn't the rest of the components apart from the mainboard identical?

I did this to my phone actually. The housing is slightly different for the phones so I had to use a dremel to grind away some walls inside the housing for motherboard components to fit. The antennae cable is a little shorter and has a tighter fit due to slightly different configuration on the N7105 board. You need to replace the charging port from N7100 to N7105 because they are not compatible (was less than 5 bucks). Overall, it worked hardware wise, but I don't know if it's the motherboard I bought or something else; I can't connect to 2.4 ghz wifi and 5ghz wifi connection is somewhat spotty. I also do not have 4g capability for some reason, only Edge, despite changing to the appropriate APN, mobile network, and having it on the 4g setting.
I may try flashing a new ROM on it later to see if that fixes things.
were u successful at this? I am in a similar situation
