Learn more about Google Maps or how google spies on us.

After a second round of the exploration of the company Google and its database of wi-fi and Wi-Fi, I have decided to look for something that has been done to find out what they have in the past.
I wanted to know what data they are passing on to their programs.
Installing a software for Symbian 9.2.

I remembered that I recently downloaded the maps from Google, but still decided to make sure that I have the latest version of the program installed, and I went to Options - Help - About the program , and found there interesting information.
Below I attach a screenshot of the information shown.


What do we see here?
Our phone shows (actually if we take out the protocol, then we will see that it also sends) to Google information about:
The OS of our phone, battery level, localization, MCC, MNC, LAC, RSSI and CellID (characteristics of the base station) and one more unimportant parameter are the names, the number of Wi-Fi hotspots and their addresses.
Consequently, Google has its own cell database and Wi-FI. Based on this database, their Latitude function works.

The parameters we are interested in are:
MCC - country code.
MNC - operator code (for example, Russia: MTS- 01, Beeline - 99, Ukraine: MTS- 050, Kievstar- 067).
LAC - local area code (set of base stations served by one controller)
CellID - base station and sector identifier.
RSSI - received signal power.
')
And so, what do we have? Rather, it has Google, and it has a very large base, which any nonmonitor would envy. But we will also have something to do with the fact that Google uses such a count. Of subscribers.

But actually it gives us good opportunities, i.e. in fact, using a specially formed query from our coordinates and a cell signal, we can obtain data on nearby streets, hotspots, etc.
The request is also described in the documentation for the Geolocation API Network Protocol link.

The principle of Google and does not hide the fact that he constantly collects information about us:
“Google’s Privacy Policy and various privacy notes for specific products describe how we use the personal information you provide when using Google products and services, including Google’s mobile products and services. In addition, privacy measures related to Google mobile services and products are listed below. ” Via m.google.com/static/en/privacy.html

It turns out that in the case of German hotspots, Google did not have the right to scan networks, and in our case it has full rights to perform these operations (and even more), because this is described in the agreement and privacy policy that almost no one reads.

So if you are tormented by paranoia, then be careful with the selection of software and familiarization with the above documents.
