Every second matters in an emergency 911 call, but out-of-date regulations may be slowing first responders down. Last updated in 2010, FCC rules mandates that phone carriers provide a callers location within 50 to 300 meters, but those requirements only apply outdoors, since, in the FCCs own words, indoor use poses unique obstacles. GPS has improved tracking significantly, but it might still be off, sending paramedics to the wrong floor, or even the wrong building. The FCC recently proposed new rules for more accurate indoor tracking — and carriers have expressed their displeasure. Mother Jones has flagged some of the complaints sent to the FCC since the announcement of the proposal in February.
