I have been looking at this “N” (see right) for weeks and have not figured out what it is doing. I have turned off WiFi so it should not find an 802.11 N networks. This was making me nuts.
It turns out that “N” relates to NEAR FEILD COMMUNICATION. If you don’t know what that is, you will soon. NFC allows your hand held device (typically a cell phone) to transfer data (like credit card information) to another device if it is VERY close to it. Sooo, if you want to pay for your Coke, you could just tap your phone to the Coke machine and bingo, you b’een charged. It is also used in Samsungs case to transfer files, pictures… between Galaxy S3 devices just by tapping the back of them together.
For now I have no use for it and like all radio’s, it is sucking down my battery, so I turn of NFC by:

Thanks for the detailed info much appreciated!
Very helpful thank you.
I tried hooking up my usb cord to my tv to no avail and the n has been there every since wtf
Hi Sam;
NFC is unrelated to USB.
USB is unrelated to TV... well, mostly; you can buy an HDMI converter cable that connects to the USB but my testing did not go well with this feature. We would see about 5 frames a second which is just terrible.
:(

THANK YOU you the best !
Does it eat up your mobile data?..
I am 99.9999% sure that it does not use any mobile data. That is the point. Near Field Communications are direct.
I think this means your S3 has the following "radios":
1: WiFi
2: Cellular
3: Near Field
I hope this helps.
thanks man ....call my provider and they say "we don't know "
And do not forget the GPS radio. It is a one way radio but radio after all.
Also there is an FM radio but it needs the earphone cable to serve as antenna.
There is also the Bluetooth, of course, but this is really a special case of wi-fi connection.
Yes, our tricorders are packed full of tiny radios :-D
Yes, all the newer smartphones have amazing tricorder like features.
Note that the "North American" Samsung S3's do not have an FM radio tuner, but the S2's and at least some of the "International" versions of the of the S III DO have FM tuners:
