Your device then contacts online servers that have a database of Wi-Fi access points and their geographical locations.

So there is a database of WiFi locations? Is this just for some predetermined and registered commercial spots? I do not see how home and business WiFi devices would automatically be added.
That does not make any sense. There is no GPS database of all home and business

Of course there is. Google maps is the most obvious example.
Traditional addresses are basically obsolete. They are used for mail, and that's it.
Provider knows.
My complete sentence was "There is no GPS database of all home and business WiFi locations"
If routers had a feature that allowed them to read and write digital phone signals, you could do away with cell towers.
When you are moving around with your phone with GPS and Wi-Fi on, your phone is collecting which location and wifi signals it can connect to.

Are you really an engineer? That would require home/business WiFi routers to have huge antennas and an effective radiated power of around 100 watts.

Do you actually know this, or are you just guessing?
A 100 watts? Really? Really, you think it takes that much energy?

Listen to me.
Google is an information collection agency. That's what they do. That's their MAIN PURPOSE and always has been. It has the side effect of allowing you to find information, and but their main job is surveillance.
Yes, I do. The fact that my phone can see lots of WiFi spots in a housing development is irrelevant. Why do cell tower antennas have 100 watt amps feeding them?
Why does the tower need 100 watts power when the phone answering back only needs well under a watt?
So you are guessing.
Even turning all the crap off doesn't stop police and first responders from tracking you. Unless your phone has legit dead battery, even off, you're trackable.
I don't think people understand this. If you want privacy you shouldn't have a phone. That's really all there is to it.
One of these days, I'll compare battery drawdown between unshielded and shielded phones. I expect the shielded phone to discharge 10X faster than the unshielded one.

If your phone is on and cannot reach a cell tower, it will expend a lot of power trying to find one. I've had this happen to me once, so I'm in the habit now when I'm in an area without good cell coverage, I just turn the phone off. Seems like a bad design, but I don't know the specifics of how modern phones work.

Dude, believe whatever you fucking like. Fuck all of you, you want to be slaves, be fucking slaves then. I'm DONE trying to explain to you motherfuckers what can and WILL be done to you.
I suspect that even off, the phone is probably spying, or could be periodically woken up by the NSA to eavesdrop, who knows?

Well, it's been a while since I've worked on anything remotely connected to cell phone communication, like 20 years, but it was because it wasn't a shaped waveform at all. You broadcast completely non directional. That's changed.
I should clarify: I would turn the phone off, then measure charge after about a week. I suspect that even off, the phone is probably spying, or could be periodically woken up by the NSA to eavesdrop, who knows?
Whoa, calm down. We were talking about a specific - that you said When you are moving around with your phone with GPS and Wi-Fi on, your phone is collecting which location and wifi signals it can connect to.
Just admit that you do not know if this is true instead of launching into your Special Theory of GoogleEvilty.

Well, beam formed a little since there was no point in a tower broadcasting upward. But the mobile phones are not beamed formed at all, so the question remains - Why does the tower need 100 watts power when the phone answering back only needs well under a watt?
Voice data isn't large in comparison to most of what we do on the Internet now, which is video.
The future of the internet in many areas will be from cell towers.

Many others have attempted Open Source phones and failed. I hope this one works, especially since I just discovered that you cannot turn off wifi or Bluetooth on Android or iOS. "Turning it off" in the controls on those phones merely disconnects you from current access points, but leaves them on so they can spy on your location with great precision and open you up to various exploits:
