CTIA’s 9-1-1 Location Accuracy Technologies Test Bed Announces Additional Testing in 2020 .

WASHINGTON – Today, the 9-1-1 Location Technologies Test Bed, LLC (Test Bed), an independent entity established by CTIA, invites vendors of location accuracy technologies to participate in vertical positioning accuracy evaluation (known as Stage Zb). The Test Bed independently evaluates the ability of wireless providers and location technology solutions vendors to meet the FCC’s indoor 9-1-1 location accuracy requirements through different technologies.

This testing round is the next step following the initial Stage Z tests conducted in 2018 and 2019. Stage Z testing focuses on emerging indoor technologies that determine the altitude, or z-axis, of a 9-1-1 caller in multistory buildings.

“Stage Zb will help us continue to evaluate existing and emerging technologies that may be critical in improving indoor 9-1-1 location accuracy and helping 9-1-1 professionals and first responders save lives during emergencies,” said Test Bed Vice President Tom Sawanobori.

Consistent with the FCC’s 2015 Order on Indoor Wireless 9-1-1 Location Accuracy, CTIA established the Test Bed to independently and transparently evaluate the performance of new and existing wireless 9-1-1 location information technologies.

The vertical location test campaign is scheduled to begin in September 2020.

All vendors interested in participating in Stage Zb of the Test Bed can visit the 9-1-1 Location Technologies Test Bed, LLC website or reach out to

Vendors who are interested in participation should submit their applications no later than March 31, 2020.
