CTIA’s 9-1-1 Location Accuracy Technologies Test Bed Opens for Additional Testing .

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 Za) in the 9-1-1 indoor location technologies Test Bed. 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 test conducted in 2018. Stage Z focused on emerging indoor technologies that determine the altitude, or z-axis, of the 9-1-1 caller in multistory buildings.

“We continue to make progress on exploring all existing and emerging technologies to improve indoor 9-1-1 location accuracy,” said Test Bed Vice President Tom Sawanobori. “Stage Za will help us evaluate new technologies that could be critical to helping 9-1-1 professionals and first responders save lives during emergencies.”

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 July 2019.

All vendors interested in participating in Stage Za 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 29, 2019.
