T-Mobile, for example,rolled outa similar approach on a regional level.

T-Mobile says some areas with the new technology have experienced up to 40 percent fewer call transfers.

“And that, simply stated, will make people safer.”

This mandate will help locate callers in an emergency by determining their correct altitude or floor level.

Most carriers currently route 911 calls based on cell tower location.

“We know that 911 transfers delay emergency response, and the winner here is our community.”

The Future of Emergency Response

Mobile routing systems could soon get even more accurate.

Another potentially game-changing innovation is known asReal-Time Kinematic(RTK) technology.

The system improves the precision of GPS by measuring the arrival time of millimeter-wave signals coming from the handset.
