Karry, do you mean "cell broadcast"?
(en . wikipedia . org / wiki / Cell_Broadcast)
Let me check it, this is a nice question. The german O2 network uses the channel 221 to transmit GaussKrueger coordinates of the currently used base station. Now I am eager to find it out. Stay tuned ;)
With the RSSI data, my intention is it to gather them for creating such maps as you can calculate (!) with RadioMobile (www . cplus . org / rmw / rme.html).
I am working and selling radio propagation calculations and prediction since about nine years. (Yes, one can earn money with it.) Of course one has to combine it with real life measurements. You can maybe imagine that all radio propagation calculations and models are somehow limited. So to find useful data either one creates dedicated measurement setups as I do or uses the most spreaded and well known cell phone networks all around us ... GSM. Working together with local carriers, it is possible to do really good and realistic measurements.
At the moment I am using (besides Rohde+Schwarz reference receivers) Nokia E63, E51 and some Huawei sticks to evaluate carrier base stations. Now i would like to do the same with my beloved Pre.
BTW: backend for 3D diagrams (this is the sellable result) is Matlab or Scilab (my favorit).
Again, you guys are far better software developer then I ever could be, so adding one data row in this SQL database takes really hours? Hmm ... maybe yes if the database (table) has to be adjusted ... and debug... I see.
