The Federal Communications Commission (FCC) has issued a Report and Order which requires Commercial Mobile Radio Service (CMRS) providers to implement location-based routing (LBR) for wireless 911 voice calls and real-time text (RTT) communications to 911 nationwide. With LBR as implemented under these rules, CMRS providers will use precise location information to route wireless 911 voice calls and RTT communications to 911 to the appropriate public safety answering point.
