What is Wi-Fi calling?

To answer your simple question ‘what is Wi-Fi calling’ –  as the name suggests is a way of placing calls to another user without using the traditional cellular network. It uses the nearest Wi-Fi or broadband connection. It is similar to a voice service. The feature is available for both Android and Apple phones.

Even if you are not in a remote place but just trying to take a call in a dead spot of your house, these calls really help you a lot. We all know about those spots in our homes. One side of a bedroom or your washroom, if you are on call in such dead spots, with enabled Wi-Fi calling feature your call will not drop or get cut.

Points to be noted

1. Given that a Wi-Fi connection’s range is limited to 150 Ft. or 46 m indoors and 300 Ft. or 92 m indoors for a router operating on 2.4 GHz.  As long, as you stay in this range and preferably near the router, you call quality will be extremely seamless!
2. The call or message history (be it for regular or online calls) is displayed in the usual call and message log.
3. As long, as your network is fine, you won’t notice any difference between a regular and a Wi-Fi call.
4. Most of the time, Wi-Fi calling is a free service.
5. You don’t need to have an additional number.

How does Wi-Fi calling work?

It works in a similar way to a VoIP application. Let’s understand it works and how to use Wi-Fi calling.

VoIP application

A VoIP application or Voice over IP application uses Voice-over-Internet-protocol technology to make calls by using a broadband connection rather than a phone line. The same technology with minor differences is used for Wi-Fi calling.

To give context, the cellular data packets are transmitted using VoIP technology to the internet. The transmission takes place using the router. Post that, the data packets are sent to the cellular network and then to the receiving or answering party.
