This video is focused on a location technology feature that Voice Over LTE, or VoLTE, -enabled LTE mobile devices need to support. As operators in North America begin to shift voice services to their LTE network, a significant—and potentially gating—factor is the support for emergency services. The Federal Communications Commission (FCC) mandates E911 services for mobile devices and operators and the accuracy requirements are tight. VoLTE E911 must meet the FCC requirements from the first day VoLTE is deployed, and the current requirement is that caller location must be provided to public-safety answering points with 50m accuracy for 67% of calls and 150m accuracy for 95% of calls. The FCC is also demanding improved accuracy and availability of E911 positioning across all parts of the country, and especially for indoor situations where over 50% of E911 calls are placed.
