APCO Asks FCC to Act on Z-Axis Petition, in Comments on FNPRM
APCO asked the FCC to act on the public safety organization's February petition for clarification of rules requiring national wireless carriers to meet a vertical location accuracy metric of plus or minus 3 meters for 80 percent of indoor wireless…

E-911 calls from z-axis capable handsets (see 2002070057). Initial comments were due Friday on a Further NPRM on advanced vertical location, mapping and 911 services. “The resolution of many questions raised in APCO’s Petition will impact whether and how to improve the location accuracy requirements,” APCO said in docket 07-114, posted Friday: “The feasibility and benefits of requiring more granular z-axis information depends on how the Commission defines what it means for carriers to deploy z-axis technology consistent with the manner in which it was tested. Which phones should consumers expect to provide vertical location information with 9-1-1 calls? How do carriers ensure that they have deployed z-axis technology in a manner that will achieve the accuracy demonstrated in the test bed?” The Industry Council for Emergency Response Technologies said “public safety’s many challenges are best addressed through technological innovation and collaboration between industry and public safety stakeholders.” The order rejected a more stringent standard, the council said: “Nothing has changed since the Order was adopted a few months ago to alter that conclusion. The establishment of a more stringent requirement, without the benefit of technical data to support it, would be arbitrary both in terms of the level of accuracy achievable and the timeframe in which it could be achieved.” The FCC asked in the FNPRM if "initiatives are underway to develop resources for mapping building heights and floor numbers," said 911 technology company RapidDeploy: “Indeed, such initiatives are underway, both private and public, at local, regional, and statewide levels.” Public safety answering points and first responders “can be ready to consume and utilize floor level information well before the proposed 5-year timeline -- many as soon as today,” the company commented.
