Recently, Bharat Sanchar Nigam Limited (BSNL) announced the nationwide rollout of Voice over WiFi (VoWiFi) services. This move aims to improve voice call connectivity, especially in areas with weak or unreliable mobile network coverage.

About Voice over WiFi (VoWiFi)

Voice over WiFi, also known as Wi-Fi Calling, is a technology that allows users to make and receive voice calls and messages over a Wi-Fi network, instead of relying solely on traditional cellular networks.

It enables seamless communication using the customer’s existing mobile number and phone dialer, without the need for any third-party applications.

Technical Features of VoWiFi

VoWiFi is an IP Multimedia Subsystem (IMS)-based service.
It works by using
Voice over Internet Protocol (VoIP) technology, where voice signals are converted into digital data packets and transmitted over an internet connection.

The service is built directly into the smartphone’s operating system, allowing it to function smoothly with the user’s existing contacts and mobile number.

Working of Voice over WiFi

When a mobile device is connected to a Wi-Fi network, VoWiFi automatically routes voice calls through the internet instead of cellular towers. This ensures uninterrupted calling even in locations where mobile signals are weak or unavailable.

Advantages of Voice over WiFi

  • It provides clear and reliable voice connectivity in areas with poor mobile network coverage, such as homes, offices, basements, and remote locations.

  • It helps reduce congestion on cellular networks, especially in densely populated areas.

  • VoWiFi calls are generally offered free of cost, with no additional charges beyond standard voice plans.

  • It improves overall call quality and user experience without requiring extra hardware or applications.

Significance of the Rollout

The nationwide rollout of VoWiFi by BSNL is expected to enhance digital connectivity, improve service reliability, and support India’s broader goal of inclusive and accessible telecommunications, particularly in underserved and indoor locations.
