this is stupid.
people that think cell phones have a place in schools are either missing the entire point of education or are simply idiots. I’m sorry, if a parent wants to get ahold of a kid drive to the freaking school and get them… it’s LOCAL SCHOOLING… as in close to home… ya know?
what a bunch of bullshit. I helped implement a device taht effectively kills cellular signals… think of lead to superman’s vision 
it’s used for radiology and other functions in hospitals where those signals are truly an issue.
anyway… give it 10 years and these will be all over schools, as they should be.
