On January 2, 2019, the Public Safety and Homeland Security Bureau (“Bureau”) released a Public Notice reminding Commercial Mobile Radio Service (“CMRS”) providers subject to the Commission’s Phase II E911 location accuracy rules of the January 18, 2019 deadline for certain Phase II requirements applicable to CMRS providers that deploy network-based and handset-based E911 location accuracy technologies (PS Docket No. 07-114).
As a reminder, CMRS providers deploying network-based technologies must meet the following Phase II location accuracy standards for outdoor 911 calls:
- 300 meters for 90% of calls (increased from 80%), in 85% of counties or PSAP service areas.
- To the extent that CMRS providers using network-based technologies have previously claimed exclusions from Phase II location requirements based on technical inability to triangulate, all such exclusions will sunset on January 18, 2019.
CMRS providers deploying handset-based technologies must meet the following Phase II location accuracy standards for outdoor 911 calls:
- 50 meters for 67% of calls, and 150 meters for 90% of calls (up from 80%), on a per-county or per-PSAP basis.
- CMRS providers using handset-based technologies may continue to exclude up to 15% of counties or PSAP service areas from the 150-meter requirement based on heavy forestation that limits handset-based technology in those areas.
The Bureau also reminds CMRS providers that they must file notice of Phase II geographic exclusions (Exclusion Reports) and updates reflecting any changes via ECFS, with copies sent to NENA, APCO, and NASNA.
