PHASE II E911 REQUIREMENTS
Posted by WDN, October 01, 2001
Today, October 1, 2001 was supposed to be the day that carriers are to meet the FCC's Phase II requirements for Enhanced 911.
As a refresher, here are the requirements as set out by the FCC. More to come on this is the near future.
See also the primer on E-911
Wireless carriers are required to provide Automatic Location Identification (ALI)
as part of Phase II E911 implementation beginning October 1, 2001, as detailed below.
Originally, the FCC's rules envisioned that carriers would need to deploy network-based
technologies to provide ALI. In the past several years, there have been significant
advances in location technologies that employ new or upgraded handsets. In September
1999, the FCC revised its rules to better enable carriers to use handset-based location
technologies to meet the Phase II requirements. In particular, the FCC established
separate accuracy requirements and deployment schedules for network-based and
handset-based technologies. In August 2000, the FCC made minor adjustments to the
deployment schedule for handset-based technologies. The E911 Phase II requirements
are as follows:
Handset-Based ALI Technology: Wireless carriers who employ a Phase II location
technology that requires new, modified or upgraded handsets (such as GPS-based
technology) may phase-in deployment of Phase II subject to the following
requirements:
Without respect to any PSAP request for Phase II deployment, the carrier shall:
1. Begin selling and activating ALI-capable handsets no later than October 1,
2001;
2. Ensure that at least 25 percent of all new handsets activated are ALI-capable
no later than December 31, 2001;
3. Ensure that at least 50 percent of all new handsets activated are ALI-capable
no later than June 30, 2002; and
4. Ensure that 100 percent of all new digital handset activated are ALI-capable
no later than December 31, 2002 and thereafter.
5. By December 31, 2005, achieve 95 percent penetration of ALI-capable
handsets among its subscribers.
Once a PSAP request is received, the carrier shall, in the area served by the PSAP,
within 6 months or by October 1, 2001, whichever is later:
1. Install any hardware and/or software in the CMRS network and/or other fixed
infrastructure, as needed, to enable the provision of Phase II E911 service; and
2. Begin delivering Phase II E911 service to the PSAP.
Network-Based ALI Technology: As of October 1, 2001, within 6 months of a PSAP
request, carriers employing network-based location technologies must provide Phase
II information for at least 50 percent of the PSAP's coverage area or population.
Within 18 months of a PSAP request, carriers must provide Phase II information for
100 percent of the PSAP's coverage area or population.
ALI Accuracy Standards: The FCC adopted the following revised standards for Phase
II location accuracy and reliability:
For handset-based solutions: 50 meters for 67 percent of calls, 150 meters for 95
percent of calls;
For network-based solutions: 100 meters for 67 percent of calls, 300 meters for 95
percent of calls.
ALI Implementation Plan Report: The FCC required wireless carriers to report their
plans for implementing E911 Phase II, including the technology they plan to use to
provide caller location, by November 9, 2000. This report was aimed at providing
information to permit planning for Phase II implementation by public safety
organizations, equipment manufacturers, local exchange carriers, and the FCC, in
order to support Phase II deployment by October 1, 2001.
CONDITIONS FOR ENHANCED 911 SERVICES
The E911 Phase I requirements, as well as certain of the Phase II requirements,
are applicable to wireless carriers only if the administrator of the designated PSAP has
requested the service and is capable of receiving and utilizing information provided. In
November 1999, the FCC revised its E911 rules to remove the prerequisite that a cost
recovery mechanism for wireless carriers be in place before carriers are obligated to
provide E911 service in response to a PSAP request. The PSAP must have the means of
covering its costs of receiving and utilizing the E911 information, however, in order to
make a valid request for E911 service. The FCC's rules do not mandate any specific
state action nor specify any particular mechanism for funding the technology and service
capabilities necessary to enable the PSAP to make a valid service request.
IMPLEMENTATION OF 911 ACT
In August 2000, the FCC adopted an Order to implement the Wireless
Communications and Public Safety Act of 1999 (911 Act), enacted on October 26,1999.
The purpose of the 911 Act is to enhance public safety by encouraging and facilitating
the prompt deployment of a nationwide, seamless communications infrastructure for
emergency services that includes wireless communications. The FCC initiated the
implementation proceeding to address the provisions of the 911 Act and to fulfill the
Congressional mandates set forth therein. Specifically, in the Order adopted in August
2000, the FCC took the following initiatives:
designated 911 as the universal emergency telephone number within the
United States for reporting an emergency to appropriate authorities and
requesting assistance, effective upon August 29, 2000;
sought comment on appropriate transition periods for areas in which 911 is
not currently in use as an emergency number, as well as on service area-
specific circumstances and capabilities that must be addressed before carriers
can deploy 911 as the uniform emergency number; and
sought comment on how the FCC should facilitate states' efforts to deploy
comprehensive emergency communications systems - for example, through
guidelines, meetings, or other information-sharing measures - in a manner
that does not impose obligations or costs on any person.
The 911 Act also added provisions dealing specifically with wireless location
information to 47 U.S.C. 222, the section of the Communications Act that governs
treatment of customer proprietary network information (CPNI) and subscriber list
information (SLI). The Commission expects to initiate a proceeding to interpret and
clarify these provisions in early 2001.
