Researchers identify why 911 calls are delayed, failed, or dropped

An estimated 240 million calls are made to 911 in the U.S. each year, with wireless devices accounting for 80% or more of these calls. Making sure emergency calls connect and stay connected to 911 dispatchers is essential and could have life-threatening consequences. MSU researchers found that in certain situations, 90% of emergency wireless calls failed to connect to 911 within 120 seconds but have developed an app to correct this.
