Winbourne Consulting Defining Z-Axis

Defining the Z Axis for Indoor Location

The availability of more accurate location fixes for 911 calls, which include the Z axis is expected to increase significantly thanks to recent action by the Federal Communications Commission (FCC). On November 22, 2019, the FCC adopted rules requiring wireless carriers to deliver 9-1-1 calls with a Z-axis metric that is accurate within three meters (or approximately 10 feet) for 80% of the indoor (wireless) 9-1-1 calls.
