Also unable to read the article no matter what tricks I use, but I'll add this nugget of info for E911 requirements. I believe we are coming up on the deadline years for when telcos must incorporate barometric measurements from barometer-carrying phones into altitude calculations so that 911 emergency response can get an altitude clue from the moment you ring. Edit: PDF source https://apps.fcc.gov/edocs_public/attachmatch/FCC-15-9A1.pdf https://apps.fcc.gov/edocs_public/attachmatch/FCC-15-9A1.pdf And edit: This is a tricky situation, because the barometer does not provide real altitude data, and if the math is done incorrectly or there is some interference, the 911 response could be sent to the wrong altitude. Perhaps there are delays with that because extracting the correct altitude from the data is extremely difficult to do with only a single phone to use a source.
