Coverage at Mountain View High School at this intersection is almost non-existent both indoors and outdoors, my daughter says she does get service in one building that is close to Thornydale otherwise pretty much unusable. In traveling to/from Mexico this past week we had far better 4G coverage in the vast expanses of open highway than she gets at school, I realize open expanse is easier to get coverage but sad that we were literally in the middle of nowhere on reservation lands with excellent coverage when in town coverage is not so great (even at my house lucky to get a single bar, maybe two outside, 1 mile from the school). She doesn't make calls while at school and texting seems to work well enough to be usable.
