Any solution that tries to pry people from their amazing magic boxes is going to fail. They're too damn good and only getting better. We just need self-driving cars and VR(/AR).

There's also a lot of room for improvement on the UI-side of things. Ideally, drivers shouldn't need to touch their phones to access the data or service they want; everything I want to do in the car ought to be voice-accessible.

My mom's SUV was totaled by a woman who was on her iPad while driving. I really don't think we'll be fixing the idiots-on-the-road epidemic anytime soon.

The solution is not only logical, but also an answer to lots of other problems: ditch the car-centric culture and move these people out from their cars to buses, trains, trams, bicycles and other forms of sustainable transport. It's not that hard, takes some time getting used to, but will do good to all of us.

a major problem preventing further adoption of mass-transit usage in my city is that it is so spread out. the Phoenix Metro area is huge and not overly dense. taking a bus or the "light-rail" would take 2 or 3 times longer than driving my truck.. Carpooling is still an option though, and a big help...

Earlier quoted context omitted.

Certainly not without FCC approval, which I'd doubt would be easy to get. The big issue (as described in the article) as that the chance of interfering with a legitimate emergency communications system is fairly high.

The FCC does not even allow cell phone jammers at prisons. The Secret Service protecting the President is probably one of the few authorized users of cell phone jammers anywhere in the country.

Guess the "pigs"# are indeed more equal than the rest of us. #And no, I don't mean pigs as in the derogatory term for the police.

Does anyone know if it would be legal to use something like this if it was sufficiently clear with big signs? I'm thinking movie theaters or coffee shops that have huge signs "Your cell phone will not work in there. If you don't agree, don't come in", etc.

So that no one can use their cell to call 911 if there is another movie theater shooting? That would be very bad.

On a related note, anyone know why cinemas don't have some form of shielding/Faraday caging to prevent people from making calls? You could shield just the movie halls themselves, so people can still make emergency calls from the lobbies.

First step: better buses, oh and stop removing routes from the bus system. (I'm looking at you Seattle and your recent voting results)

And perhaps transit mode off the road needs to be seriously invested, too. (Trains, etc.)

Even as current state, buses are far from usable, unless perhaps you are living in the heart of the city...

So school shootings and medical emergencies go unreported?

Doesn't every school have a landline somewhere in the building?

It does, yes. Actually schools have several of them. What i said was a knee jerk reaction to "actively attempting to make it impossible to use cell phones in a school", because two obvious good use-cases of them are 'school shooting and reporting it instantly'; and 'my teacher just collapsed, help'. But yes, footwork could help fix a medical emergency (run to the nurse / another teacher); and chances are, someone heard a gunshot somewhere or someone can get to a place where they can report the shooting.

"Agents from the FCC used direction finding techniques to find that strong wideband emissions were coming out of a blue Toyota Highlander SUV driven by Humphreys." This I find interesting and am curious what devices they had to obtain in order to accomplish this. I used to work for a telco that, to this day, continues to have this very issue with _someone_ in a remote rural location. By the time the NOC can inform lo…

It was a strong radiator (perhaps broadband) and that makes it easy to geo-locate. You can use distributed mobile sensors and TDOA to pinpoint the location.

Tracking radio signals with two spectrum analyzers, two Yagi type directional antennas is pretty trivial. If you know the probable location set up two (or more for a faster fix) people with gps units and their hand held antennas. Tell them the frequency and they can read back their headings (you know their position from GPS). After about 3 minutes of this you have the transmitter location to a precision of less than 12" if it isn't moving.

Why not shield your store instead of blasting more radio waves?
