IPLOOK VoWiFi Solution To Enhance Competitiveness of Operators

  • Wi-Fi Calling (VoWiFi) is an IMS-based voice calling technology similar to VoLTE. Based on ePDG, HSS/3GPP AAA and IMS, IPLOOK VoWiFi solution enables users to achieve high-definition voice or video calls over Wi-Fi , and seamlessly switch with VoLTE, when accessing the mobile network via Wi-Fi hotpots. Wi-Fi serves as the RAN to access the carrier’s EPC and  IMS  networks.
  • The VoWiFi solution effectively supplements VoLTE. Operators can retain users and attract a broader user base with VoWiFi, exploring potential revenue streams.

FAQ

What is Voice over Wi-Fi (VoWiFi)?

Voice over Wi-Fi (VoWiFi), also known as Wi-Fi Calling, is an IMS-based communication technology that enables users to make voice and video calls over Wi-Fi networks instead of relying solely on cellular coverage. It improves call quality and connectivity in areas with weak or unavailable mobile signals.

VoWiFi works alongside VoLTE to provide seamless communication continuity. When cellular coverage is weak, users can automatically switch to Wi-Fi networks for voice and video calls without interrupting the communication session, improving overall user experience and service reliability.

VoWiFi helps operators improve indoor coverage, reduce international roaming costs, offload mobile network traffic, increase customer satisfaction, and expand service availability in difficult coverage areas such as high-rise buildings and remote rural regions.

IPLOOK’s VoWiFi solution is based on IMS architecture and integrates with components such as ePDG, HSS/3GPP AAA, EPC, and IMS platforms. Wi-Fi networks act as the radio access layer connecting users to the operator’s core network infrastructure.

Yes. IPLOOK’s VoWiFi solution supports intelligent handover between Wi-Fi and cellular networks, enabling uninterrupted voice continuity when users move between Wi-Fi hotspots and LTE/5G mobile networks.

The platform provides highly secure network access through carrier-grade authentication, encryption, and IMS security mechanisms. This ensures secure voice and multimedia communication across both public and private Wi-Fi environments.

VoWiFi is ideal for highly populated urban environments, dense high-rise buildings, indoor enterprise environments, remote rural areas with poor cellular coverage, and international roaming scenarios where users need reliable and cost-effective voice connectivity.

By extending voice services beyond traditional cellular coverage areas, operators can enhance service quality, reduce churn, attract international travelers, improve network efficiency through traffic offloading, and deliver premium HD voice and video experiences across a broader range of devices and environments.
