Trusted Access VoWiFi: A Secure Path to Better Indoor Connectivit
In voice communications, two factors consistently matter most: stability and security. Yet both can be challenged in common scenarios. Indoor environments such as shopping malls, airports, or subterrance facilities often suffer from weak cellular signals. At the same time, international roaming remains expensive for many users.
To address these gaps, Voice over Wi-Fi (VoWiFi) has emerged as an important complement to mobile networks. By extending voice and video services over Wi-Fi, operators can enhance user experience while reducing costs.
Among the deployment models, Trusted Access VoWiFi is attracting increasing attention. Compared with the Untrusted mode, it provides a direct, operator-managed path that minimizes security risks and latency, while offering better control over service quality.
Why Trusted Access VoWiFi Matters
Security First
Traffic remains within the operator’s own Wi-Fi and core network, reducing exposure to interception or manipulation.
Low Latency, High Quality
Eliminating IPSec tunneling shortens call setup time and supports smooth HD voice and video.
Centralized Control
Operators can enforce access policies and QoS, ensuring compliance and meeting enterprise SLAs.
Ready for the Future
The architecture naturally aligns with 5G cores and VoNR, easing the evolution toward next-generation IMS systems.
