Reliance Jio and Airtel are Rolling Out VoWiFi Across India But How Does it Differ from VoLTE

The biggest telecom operator in India right now is the Mukesh Ambani led telecom operator, Reliance Jio. The telco boasts of having the largest number of subscribers above the mark of 350 million. This means that Reliance Jio has the responsibility of bringing the latest technology to its subscribers. Bharti Airtel is the direct competing telecom operator in the industry with Reliance Jio. Now, when we are talking about network technologies, we cannot get by without talking about the latest tech which is reaching out to the users, and it is Voice over Wi-Fi or popularly known as VoWiFi. This technology is slowly being rolled out to the entirety of users, and we are getting reports from various parts of India about how people are getting to see icons on their status bars which define VoWiFi availability in their area, on their phone and on their network. However, the VoWiFi sounds similar to another technology which the consumers have been now using for a few years, which is VoLTE. It is easy for the subscribers to be confused between the two technologies, and it is a question as what are the differences between these two. We describe both of these in layman’s terms.

VoWiFi and VoLTE Differences Explained

To understand why Voice over LTE or VoLTE first came into the picture, it is imperative to understand the need for it. Previously, on the 3G and 2G network, the calls used to be made on a circuit-switched (CS) network which was basically the 2G network responsible for carrying calls. However, the LTE network is a packet switching network, and as you know, packets, simply put, are nothing but data which is carried over the network. Now, with this, we can understand that VoLTE is a technology which carries calls over the packet switching, or data carrying network. Now instead of a solution which falls back to the old (circuit switching) network every time a call is made, the VoLTE network ensures that your internet is on while you are making a call.
