Work Remains on Vertical Access Standard for 911 Calls, CTIA Tells Pai Aide

CTIA told an aide to FCC Chairman Ajit Pai that work remains before carriers can consistently transmit vertical location data on 911 calls to public safety answering points. "Consider a phased-in approach that reflects the nascent and evolving state of commercially available vertical location technologies that will be demonstrated in the upcoming 9-1-1 Location Accuracy Test Bed LLC’s Stage Za,” it recommended, posted Thursday in docket 07-114. Carriers' June comments supported a 3-meter standard for indoor wireless 911 calls, saying technological challenges need solving (see 1906190011).
