OET 71 Committee

• Accuracy Testing to ensure compliance with
  requirements (50 meters, 67 of the time)
• Functionality testing is a different issue
• FCC issued Guidelines for Testing and Verifying
  the Accuracy of Wireless E-911 Location Systems
• ESIF Subcommittee G - High Level Requirements for
  Accuracy Testing Methodologies
• Committee to define issues regarding the method
  and application of accuracy testing

4
Stakeholders

• Federal Communications Commission (FCC)
• Public Safety Answering Point (PSAP)
• Wireless Service Provider (WSP)
• Local Exchange Carrier (LEC) or PSAP equipment
  provider
• Wireless user

5
Issues

• Definition of test area
• Frequency of certification/testing
• Access to test data

6
Test Area

• Possible options
• Network-wide
• Statewide
• Market-wide
• PSAP area
• Smaller areas require more testing -
• Larger areas limit usability to PSAP

7
Frequency

• Possible options range from continuous to testing
  only once
• Depends on the amount of change to the network
• Predictive modeling may have a role
• More frequent testing drives up cost
• Infrequent tests may delay discovery of problems
• Test area size has an impact on this issue as well

8
Access to Data

• Possible options are to provide access or not to
  provide it
• PSAP want to know level of accuracy
• If test area larger than PSAP area, PSAP may want
  access to larger data set
• Test data may include proprietary information
• Carrier may be compliant and not meet PSAP

9
Conclusion

• Key issue is compliance testing versus
  informational testing
• Areas of consensus
• Single PSAP may be too small of an area
• Some informational data needed by PSAP for
  determining reliability of location
• ESIF document had initial release of document
  from Subcommittee G
