It’s been a while since I released my Profone tracker. I think now it’s time to write a little about it, how it works and how you can collect the data.
It’s not a new tool if you ever try my GSM and WiFi tracker. As a matter of fact, it’s a combination of the above mentioned tools, the sole purpose is to improve accuracy. The only difference is that I introduced signal strength into the algorithm, and it works as follows.
s1 = 65;
s2 = 75;
s3 = 70;
s4 = 69;
s5 = 81;
s = s1+s2+s3+s4+s5;
w1 = (s-s1)/(N-1)*s;
w2 = (s-s2)/(N-1)*s;
w3 = (s-s3)/(N-1)*s;
w4 = (s-s4)/(N-1)*s;
w5 = (s-s5)/(N-1)*s;
lat = lat1*w1 + lat2*w2 + lat3*w3 + lat4*w4 + lat5*w5;
lon = lon1*w1 + lon2*w2 + lon3*w3 + lon4*w4 + lon5*w5;
Here s1 stands for the signal strength of the first the cell tower or WiFi AP, w1 stands for the weight of $1, and N stands for the total number of cell tower or WiFi AP.
At the moment, there is no other cost effective solution other than mathematical formula to improve accuracy. If you care enough about the precision of location, use GPS instead.
To use my new tool, you need to find more than one cell tower or WiFi Access points, either on PC or mobile devices, and there are many apps to help.
I myself use Net Monitor to collect those data, including MCC,MNC,LAC,Cell ID, and MAC address. You can find many other apps too. Once you have the data, you can enter them here http://cellphonetrackers.org/gsm/.
I am still working to tweak the algorithm, so the result you get may vary. However I do not think there will be any huge change.
