APCO Files Z-Axis Petition for Clarification
On Friday, February 7, 2020, the Association of Public-Safety Communications Officials-International, Inc. (“APCO”) filed a Petition for Clarification (“Petition”), in response to the Commission’s Fifth Report and Order (“Order”) in the Wireless E911 Location Accuracy proceeding, which adopted rules to require wireless carriers to meet a vertical location accuracy metric (“z-axis”), for wireless E911 calls of plus or minus 3 meters and geographic requirements for the top Cellular Market Areas (“CMAs”) (PS Docket No. 07-114).
APCO seeks clarification of the Commission’s rules regarding: (i) how carriers can ensure they deploy z-axis technology in a manner that will achieve the accuracy demonstrated in the test bed, including the scope of handsets that must be tested and related issues and when retesting is required in light of the CTIA’s Stage Z Test Report; (ii) how emergency communication centers (“ECCs”) should seek enforcement of the vertical location accuracy requirements; (iii) when carriers must provide floor level information in addition to the altitude of a 911 caller; and (iv) what information carriers must include in their quarterly reports. APCO offers specific clarifications for these issues.
APCO requests “swift action” by the Commission to ensure there is no risk of delay with respect to the location accuracy benchmarks. As a reminder, the rules in the Order will take effect on March 16, 2020. As noted in the Federal Register, compliance will not be required for Sections 9.10(i)(2)(ii)(C) and (D) (April 2021 and April 2023 3-meter metric benchmark compliance deadlines), (i)(4)(v) (required z-axis use certification), (j)(4) (providing confidence and uncertainty data, and where available, floor level information) until the Commission publishes a document in the Federal Register announcing the compliance date.
The Commission has not yet published this Petition in a Public Notice.
