Where or how are the cell site locations read? Are the lat/long transmitted within the info the cell site sends out? Or is a lookup done from the cell id over the net?

It's very interesting to see the location of the nearby sites around me! One of them shows smack bang on the roof of a nearby school, which I am surprised about.

Thanks again
Mike

It often takes me several attempts to start/stop the application before the long/lat of the cell site will come up even though I may be sitting in the same location. Also along the same issue, if I can get the long/late to come up, when I am driving, if I see the phone change to a new cell site, the long/late does not update to the new tower, it seems to be the same as the last tower. If you would like for me to do any logging, debugging, etc (you will need to tell me how), I am happy to get you more info.

A couple of things could be going on... First, for GSM sites, the cell site location is retrieved from Google based on the cell id. This requires a network connection which may be a little unstable during a handover. In Options, try setting "Cell site loc timeout" to 10 seconds or so.

Second, there are cases where the cell id will change but show the same location. Either the carrier is broadcasting 2 different cell ids from the same physical location, or Google doesn't have the correct location. If it happens all the time, then there's another problem.

Give the timeout a try and see what happens. If it doesn't help, let me know and we'll do more troubleshooting.

The only way it works for me is to get my exact location by going into the program and clicking to show my location on the map. If I just try to use googlemaps normally, it will still only give a location radius of 1100 or so meters

I'm not quite sure what you're asking.

Will do, its still a great application.

For CDMA networks (which isn't going to help you :) ) the cell site location is broadcast as part of the signal. For GSM networks, I call google with the cell site id and it returns the lat/lon of the site. How they maintain their database is a mystery.

So can view multiple locations on BBMaps; ok.

I am using a Bold (OS:4.6.0.190)

I did try the open multiple, but because I don't have BBMaps installed (using Google), it obviously won't be able to open it.

I'm loving the functionality. One question, the "write debug messages..." option, what is that used for?

I'm hoping to be able to track where I'm having call dropout issues on my carrier's network. Will it log this type of info?

Oops, sorry for the late reply. The debug option writes info to the system error log. Since it slows things down a bit, you should only turn it on if I ask.

My original intent was to help diagnose and report signal problems.

I'm using the new 8350i Curve on the Nextel network. Will this utility work on this phone?

RemyJ 01-12-2009 10:03 PM

Unfortunately, this program doesn't support the Nextel network. I don't have any device to test with and the simulators aren't that great with iDEN support. Sorry.

For example:
I open the signal-loc program, and let it read my location.
Then I go to "show current loc on map" (which I have set in the options to use googlemaps)
Googlemaps opens, and shows my current location

So my question was if googlemaps is suppose to continuously use the signal-loc program to constantly update and show your location while you're moving? Or is it only supposed to show you that one specific location when you choose the "show current loc on map"?

RemyJ 01-13-2009 10:31 AM

Ah. Now I understand.

When SignalLoc opens GoogleMaps, it's just passing in a single set of coordinates and asking GoogleMaps to view that location. While GoogleMaps is showing that location, it's also doing what it would do if you opened it from the homescreen...finding your location using the GPS and database lookups directly. It does not use SignalLoc for anything.

Your suggestion worked perfectly. I set the timeout for 15 sec and it automatically logged about a dozen unique cell site for me this morning.

Thank you again for such a great application.

Glad to hear!

just a quick question... I have the blackberry storm, and your app works pretty good considering that its not made for it, but the thing that i dont get is why it wont tell me the lat and lon of ANY of my towers...
any ideas?
ps my carrier is Verizon...

ps2 haha
everything else shows up fine.

clectcar 01-15-2009 05:51 PM

Sending TXT or email with Lat/Lon data?
 
Want to be able to easily send a quick TXT or email with my Lat/Lon data. This data would be posted to a web page like location.clectar.com or clectcar.com/location
This feature will be used when running late to save a voice call.
I know this is a feature of the new Palm is there a Blackberry App?
Also the raw GPS data my 8820 from AT&T does not show altitude? Is there an altimeter application?

Yeah, I just can't do anything with Verizon right now. Maybe someday. :)

Interesting idea. I could probably add something like this in the future.

I don't have a problem getting altitude on my 8820. Is it missing on both the main screen and the GPS Details?

Andyn 01-15-2009 07:57 PM

I keep gettiing error code on the OTA download. Can you repost correct one? Thanks!

RemyJ 01-15-2009 09:39 PM

I just re-uploaded the file but it looks like it's still not working. I'm still checking.

ninety5teg 01-21-2009 09:28 PM

so guys..u need GPS to use this app right?

Not necessarily. You can still get radio information and possibly cell site location without a gps.
