As a mobile operator, understanding how to cost-effectively extend Voice over Wi-Fi (VoWi-Fi) to improve coverage in weak signal areas or dead spots, is key to enabling emergency services communications.
This report outlines how OpenRoaming can be used as a global extension of traditional mobile voice services, combining SIM-based authentication, emergency call routing and accurate location detection to deliver lower cost roaming-friendly emergency Wi-Fi calling. It also demonstrates how OpenRoaming’s bronze performance tier supports VoWi-Fi with sufficient Quality of Service (QoS) to support emergency calling, as well as providing international emergency fallback when a cellular service is not available.
