Short Question to Hardware Geeks - Galaxy S II Q&A, Help & Troubleshooting

Hey. can anyone tell me what hardware that is? Is it the GPS?
http://q24.img-up.net/?up=IMG_201204xttc.jpg

Factory signal test point for one of the radios. Probably cell or GPS. All phones have at least one of them.
Not for public use!

AFAIK it is the auxiliary aerial/antenna connector.

my xperia play has the same thing but the connectors to the antenna is broken. could this be because of this my gps doesn't find any satellite? I still got phone/data etc.

Whatever you do, don't try plugging anything into it. I have heard of people experimenting by plugging external antennas into that port, which ended up causing COMPLETE signal loss afterwards.
It seems if you plug something into that port which is not meant for it, then it may or may not end up breaking an internal connection for the antenna.
I say may or may not, but I, for one, would NOT want to risk it.

GPS Antenna?

I noticed this item for sale and was suprised because I was under the impression that it was determined that GPS didn't work on the Hermes due to technical limitations even when using a Trinity radio. Go figure.
http://cnn.cn/shop/8525tytnhermes-antenna-p-1615.html
pof has been alreayd pmed about this yesturday. waiting for a reply from him to see if he is willing to buy to see if it'll work. if you read more closely you would find the gps is missing the antenna and it requires lost of work to get one in there. this might be able to go in where u put a gsm antenna but lets wait for pof to see what he says.
aha... thanks for the update.

Would be excellent although the Hermes GPS is not Sirf III....
Anyone tried this one?
got pm from pof. the antenna will only help bluetooth gps and not the internal gps. oh well. thanx to pof for saving us the trouble of buying then finding it wont work.
damn man, i bought that antenna as soon as i saw it up!! soooo... like..... theres nothing i can do with this??
ok, it doesnt seem to work.
but it has to help the internal gps, the way it seems SHOULD function wouldnt make sense to help the bluetooth gps. ive seen many other cable GPS like this one on the internet. anyone else buy this?
I'm not sure I follow the function of the antenna....if it is just helping the bluetooth gps, is it then more of a bluetooth antenna, or does it just do nothing for the 8525?
I thought the bluetooth gps was its own antenna, otherwise what would the purpose of it be? Thanks!
I know this sounds sketchy... I read a post a while back about this port where you can attach antenna. A person working with the GPS project for the Hermes TyTN device discovered this port and connected a different model of antenna from Radio Shack. He went on stating that this port is for GPS. NOT Bluetooth When he connected the other style antenna he noticed both his reception (data,voice) increased along with the number of satellites he could acquire.
This is in one of the threads realated to the GPS. He has pictures and stuff too.
I stand corrected.. This was not found in the development thread of GPS with the HTC TyTN device.. This was in a thread where the person took apart their device and showed different pictures of the ""guts"" I'm trying to find the link for the thread now..
any updates on if this worked or not?
I do remember reading somewhere about how people were trying to physically build in a small GPS device into there 8525.
Although nothing about this antena though.
Makes me wonder if there is an actual built in GPS reciever inside the phone.

No but I think *some* of the hardware necessary is present. Why not just use a bloutooth GPS rather than having one tethered?
if anyone could post an update it would be appreciated...
what i have learned is that the gps antenna posted on cnn.cn is a type that is supposed to amplify and intensify the signal for your bluetooth gps... but this still confuses me. im guessing it boosts the signal for that the bluetooth attempts to pick up, but why am i plugging it into my 8525 then??
i hope there is some sort of use for this paper weight... besides the paper weight.
Theres no way that thing would fit inside a hermes is there?? It looks huge.. the kind of antenna youd need in a hermes is a tiny one shaped to fit into the top of the phone...
That anteanna is simply that.. a gps external antenna.. theres thousands of those available..
you can use it on a gps navigation system with an antenna connector in order to position the antenna for better reception.. like if you have a coated windscreen that gps cant get through you can use that lead round to the sunroof or back window to allow it to gwet signal while still having the gps unit under the windscreen where you can see it..
That thing is a standard GPS antenna.. the one needed would be a tiny thing.. with no wire and a whole load of soldering and work to fit it... it will probably never happen.. certainly not with something off the shelf like that id imagine. (you could maybe strip that down and get at the actual antenna inside.. but i highly doubt it would a)be small enough, b)fit, c) work afterwards or d) be in any way easy enough to acheive.
From the pictures on the site it looks like that thing plugs into the external antenna socket on the hermes.. but that wont give you gps.
It might improve signal quality in the car though..as it will probably work in some way as a GSM antenna.
(Have you tried plugging it in under the litttle rubber cap on the back of the phone as shown and seeing what happens - it may of course blow up the phone since it ISNT designed to go in this hole!)
Bluetooth gps is a lot better...becuase it is wireless...I have the holux 240 (smallest on the market)...and it can pick up signal inside my house
The GPS was investigated already for the TyTn, it will never work. The chip has the GPS capability however, there are many pins tied to ground. It would take major modification to attempt to use the internal GPS.
Use bluetooth like Holux, forget plugging anything into the rear antenna port. You have been warned!
so what is the deal? are you telling me that if i buy this external antenna http://cnn.cn/shop/8525tytnhermes-antenna-p-1615.html a gps application will not work? if not how can i get navigation on my device?
explain to others as it was explained unto you!

if you read carefully, you will finally understand that not having it is not going to deny your hermes a gps app.
External= the outside; outer surface; exterior.
antenna=a conductor by which electromagnetic waves are sent out or received, consisting commonly of a wire or set of wires
therefore external antenna mean outside the unit,
gps application = software for use inside the unit
Options therefore:
1. TyTN + INTERNAL BT antenna + BT gps receiver + gps app = works fine
2. TyTN + INTERNAL BT antenna + BT gps receiver + gps app + External antenna(plugged into little hole on back of TyTn not your butt = works much better (because of better reception).
Therefore, unless you install TOMTOM 6 on your pc and expect it to work on your PPC thats the only way it wont work.
Even easier to understand is this:
Imagine you are in your car and you are driving you want to listen to music(find a route) on the radio(your TyTn). Its easy to find your favorite station(gps sat) as your radio(TyTN) already has an
External antenna if you were to unplug the external antenna then you would only be able to pick up a few stations but the radio would still work.
and to the question of getting navigation on your device, you would a) have to install a gps mapping software(TOMTOM navigator comes to mind) b) have a wired or unwired gps RECEIVER. that is all.
Hope i explained it good enough.
FYI I'm using TomTom navigator 6 and Qstars 32 channel bluetooth receiver on my Hermes and it works just fine, and i dont have an external antenna.
If you need any more help feel free to pm me.
Cheers.

Correct.

Not quite correct. For the external antenna to improve GPS reception it would need to be plugged into the GPS receiver - not the phone. Plugging it into the phone will be a complete waste of time because the phone does not 'do' GPS. Wired GPS receivers can't be used with the Hermes - it has to be Bluetooth.

External antenna for wifi ?

Anyone know of a possability to have an external antenna for wifi or anything else that would help increase or focus the signal to get a better/further wireless connection ?
Any ideas are welcome even if it means working (soldering) on the actual board of the Tytn if anyone has done something similar please post your findings here.
Tytn has an external antenna connector under a little cover on the case. Wilson sells antennas and cables and such for it, plug and play.
http://www.wpsantennas.com/
Thanks for the reply Bro, but will this boost the wifi module or just the phone signal ?
Just the phone signal as far as I've read. I'm not sure though.
I'll be trying it out as soon as mine gets here and I can let ya know, I need one for trying to get reception in the rural areas I go to often.
I have read somewhere on this forum that using the atennas that plug into the port on the back are a bad idea in these phones cuz the soders on the board break easily if you do and you lose all phone signal. I couldnt find again where I read it, sorry. So be careful if you do it.
Thanks for the heads up bro, I don't mind the phone signal (aside from tunnels) but I do want to boost the wifi, I guess we're stuck with this till a better phone comes out
im sure you could maybe, make some freak monster connector for the wifi antennas? nobody has done that? isnt there some basic internal one? or how does the wifi signal get broadcast/received?
yeah its possible but I don't want to fry the board if I put something that draws more power than the board can handle (because it sends and recieves) so I wanted to see if some electric engineer or hobbyist has ventured something like this before
your better off with some wrt54g(s) with ddwrt on it and use it to connect to it and then use the wrt54 to connect to whatever it is that you want for range lol i dont know in what situation your in... if its portable then ya the router thing would not work well if in car? or some other place then that would be the best choice heh
but if your connecting external antenna then its not really that portable anymore is it
Sounds interesting... thanks for the info I look into that,
I have no problem at home or at Uni but in hotels I usually have to point the device around to catch a signal (heads up that's where the base for wifi is) and the signal is so weak it disconnects or gets real slow somewhat annoying, still better than carrying a laptop around on small trips.
i'm willing to open mine up for better wifi, i would just like a guide or atleast some pictures and pointers with do's and don'ts.
i don't NEED my hermes, but i do love it enough to want it to continue to operate.. heh.
I took mine apart already i wanted to put the bestskinever on the screen its self so while doing that i was going to check out the insides and it was a pain to get it on without any lint and stuff on still got a very small one but its nice i cut the exact size of the whole LCD not the screen dimensions
so it covers it all... anyway
i saw both BT and WIFI internal antennas there... I really did not see any connector... though something that looked like one but i didnt pay much attention it was very small maybe .200" or so
I would assume you could un solder the internal wifi antenna but i would not recommend that... as there are i believe other resistor/capacitor and hmm coil that work for the right antenna length and so on... I THINK I havent done any electronics in a long time and never bothered with such devices and or high frequencies so I would not know.
I would recommend finding some other online forums dealing with the 2.4ghz wifi stuff and learn or ask questions if its possible to make a connector for the phone.
This would be indeed a great DIY project to add to the archives
once again i would recommend that you get a cheap wrt54 put dd-wrt on it... config it properly for it to connect to other devices, they even have scripts to have it connect to open connections and the ones with strongest signal or you could config it manually through the web gui
that is far better IMO then modding your hermes heh, as i would think you would need an amplifier not just external antenna as that only might increase your sensitivity or a little better quality in signal but to boost the transmit power you would need an amplifier
http://dd-wrt.com
there you go find the right one with the right version that will work with dd-wrt they only run like 50 bucks or so… and plus you can use it for anything else… you can boost the transmit power on them as well as replace the generic antennas

Anyone know of an External GSM/GPRS Antenna port on TP2?

Does anyone know if the T-mobile version of the Touch Pro 2 has an external antenna port?
I travel through Texas and Use T-mobile (The coverage is imperfect but can be improved with an external aerial antenna)
In the past I used the Tmob Wing which had a rubber pop off cover on the back that allowed access to the antenna port.
I really miss using my external antenna. I've searched Google and XDA with no luck. Called Tmob PDA support no help there.
Any help on locating this elusive port would be appreciated.
Thanks,

err that threads about gps antenna ports, hes on about gsm
For more clarification not GPS but GPRS/GSM
I have this antenna from Wilson Electronics.
http://www.wilsonelectronics.com////ViewProductB.php?ID=21
This for 806-866 MHz / 896-939 MHz / 1850-1990 MHz.
These antennas drastically improve all cell use and improve battery life in the process because the phone does not have to work as hard to acquire or boost a weak signal.
I also believe this makes mobile phone use safer with regard to radiation.
Anyone remember the old days of Cellular? Everyone had a cell antenna on their car. This antenna is similar to those.
I hope someone can help me find out if the TP2 has an antenna port like my T-mobile Wing had.
Thanks,
M
Fil - minoch may be looking at GSM/GPRS external antenna connectors on the TP2, but the themes are connected. There are no - zero - external antenna connectors on the TP2, whether you're looking for GPS, or cellular antenna connectors. It's the single failing on the TP2 that I can identify, regrettably.
Depending on your country, re-radiator antennas for GPS and/or cellular signals are available to mount in your car, but you must look carefully to see if such devices are legal to use in your country.
minoch - I would add that the antenna linked above by you is all well and good, but without an antenna connector (socket) needed on the back of the phone, it's about as useful as a roof rack on a helicopter.
Thus, a re-radiating device of some kind is required.
This article should help you understand the tech behind the solution to the problem: http://www.tech-faq.com/cell-phone-signal-booster.shtml
Thanks for the information Roger.
I suspected this was the case but hoped I was wrong. I guess I'll have to find some sort of induction connection (Those antenna decals that have a wire to hook to an external antenna) It won't be anywhere near as good as a direct connection but hopefully it can help a little.
A shame such a nice expensive phone as the Touch Pro 2 would not have any antenna ports. I guess HTC had to cut cost too..........Damn this Economy.
Thanks,
Minoch
Must admit, it surprised the smelly stuff outta me when I realised there wasn't an antenna connector on the phone. really silly ommission, given all the hooplah regarding hands-free usage while driving your car, and all that similar malarky.
Oh well, guess they throught that the internal antenna was good enough, or, as you suggest, they had to trim down the expense by dropping an external antenna connector and associated printed curcuitry, housings and case adjustments for a grand total of maybe 3.50 GBP per unit before packaging (with adjustments for economies of scale, etc)?
*shrug*

[Q] Changing Wifi / Bluetooth Cable

I believe that my wifi/bluetooth cable is broken, as I have no wifi or bluetooth signal since dropping my phone as reported in a previous post of mine. Can anybody advise me on the difficulty of undertaking this repair myself, does it involve complete disassembly of phone, any soldering etc. If this is the case I don't feel confident enough to do this so does anybody know of someone who does this sort of repair, I have found the cable on e bay for £7 and it looks like it has push on connectors ?
What exactly do you mean by the "WIFI and Bluetooth cable"? WIFI and Bluetooth are wireless, that is the entire point.

[Q] Weak or no signal on GTI9100

Recently my provider signal got so weak that now if I am indoors the signal is gone until i go outside. Tried to upgrade via Kies to ICS but the problem persists.
When I stick a small piece of wire in the external antenna connection, my signal goes to full and is perfect!? Is this a hardware or a software problem?
It seems that the internal antenna is not responding because as soon as I remove the wire the signal is gone or is minimal.
For now I keep the wire connected behind the cover and the phone is usable.
As I can see this is a common problem and many complaints are posted on this topic all over the place.
Can anybody help? Thanks in advance.

Internal antenna
Thanks for the link,
Unfortunately I made a mistake by trying to connect an external antenna, not being aware of the consequences. Reading the posts it looks like I will have to bridge the external antenna socket and connect it directly.
Time to bring out the soldering gun and get to work.
I will try a few other options in the meanwhile.
Sh.. happens, anyway thanks for the help, regards...
