MacinJosh Posted April 19, 2012 Share Posted April 19, 2012 For those of you who have an iPhone, you can access Field Test mode by dialing *3001#12345#* and then hit call in your phone dialer.

mirskyc Posted April 19, 2012 Share Posted April 19, 2012 Which number is the ID of the cell tower I'm connected to? None of the numbers seem to match any of the numbers of the towers I'm near according to the maps in the sponsor forum. Is that number not on those maps?

MacinJosh Posted April 20, 2012 Author Share Posted April 20, 2012 Unfortunately, I don't know how to find out which tower you are connected to. One thing that may come close is Base ID, but even then I'm still not sure. I will look into it more and let you know. 1 Quote Link to comment Share on other sites More sharing options...

No service is -105, does that mean I had negative service?

Sent via Forum Runner on my jailbroken iOS 5.1 iPhone 4 That would still be no service, it's just that your phone was no where near a tower. Are you on at&t or T-Mobile, as you mentioned GSM.

And I have that problem indoors every once in a while on my Evo Shift. Signal just disappears and then comes back. It's probably happening when it changes towers to compensate and provide better service, which is more draining on the battery when I am equally distant from 2 towers.

It's the Sprint crap zone. I get -93 in my apartment and then I step across the street into -70.

I did discover that Base ID is the actual tower that you are connected to, however, I can't match them up with the tower names in the Sponsor section.

S4GRU Posted April 20, 2012 Share Posted April 20, 2012 I believe the BaseID is the sector you are tied to. I think that's accurate. I live next to a Sprint site in New Mexico. As I change sectors around the tower, the Base ID changes. The Base IDs are in no way connected to Sprint Site ID's. The only way you can connect the two is geographically through GPS coords.

EDIT: I realized after that my reply is useless as it doesn't show any correlation between the phone and the S4GRU maps. The PN is how your location is determined internally. I'm sure someone here has the know how to assign a PN with the location names Quote Link to comment Share on other sites More sharing options...

utiz4321 Posted July 26, 2012 Share Posted July 26, 2012 If I wanted to see all the avaliable evdo channels how could I do that on my iPhone? When I use this code it just tells me what channel I am on. Thanks. Quote Link to comment Share on other sites More sharing options...
WiWavelength Posted July 26, 2012 Share Posted July 26, 2012 If I wanted to see all the avaliable evdo channels how could I do that on my iPhone?

LookInToMyEyes Posted August 11, 2012 Share Posted August 11, 2012 (edited) So I have a few questions about Field test. 1) what is the best dBm. 2) My Field Test show 1x and 1xEV-DO so this means I don't have eHRPD on my tower? If that even means that. I am a newbie at this so bare with my lack of understanding. 3) What does 3G fall under? 1x, 1xEV-DO or none? 4) If possible which one of these is the fastest and how fast they run? Did I miss one? Thank you for answering my questions, I don't expect them all to be answered, but it will help me better understand them.

Thank you for answering my questions, I don't expect them all to be answered, but it will help me better understand them. 1. The best dBm varies from device to device, however, I have never seen anything greater than -65dBm on an iPhone. (This is partly because I don't get around to too many towers, and I live in weaker signal areas.) 2. The iPhone won't tell you if you have eHRPD on your local towers due to the fact that the iPhone 4/4S lacks LTE. 3. 3G is EV-DO. 4. 1x shows what tower you are connected to as well as what frequency you are connected to as well. 1xEV-DO shows the frequency that you are connected to as well. They both show other things such as the tower identifiers like base station id. I don't have my friends iPhone in front of me right now to check the rest. 1 Quote Link to comment Share on other sites More sharing options...
