Here’s Why Video Calls Over Wifi Are So Much Better

With a significant percentage of our workforce working remotely or in hybrid setup, video calls have become an essential part of our lives. Even at a personal level, people are trying their best to stay connected to their loved ones using regular video conferencing.

Keeping all that aside, we all know that video calls are peak internet activities. Did you know that these calls use both uploading and downloading processes simultaneously for continuous data transmission? Let’s understand this in detail.

Factors affecting a video call quality

A video call’s quality is affected by 3 main factors. There can be other factors involved too according to the ISP or network you have chosen.


It is the capacity of an internet connection. Bandwidth is the maximum amount of data which can be transmitted over an internet connection at a given period of time. People often confuse bandwidth with internet speed. Whereas bandwidth is just volume of data which can be received every second and speed is how fast the data is being received. Higher bandwidth leads to better internet speed.

As mentioned above, video calls are peak internet activities. Therefore, if you have good bandwidth, you can make quality video calls.

With wifi price so low these days, it is better to make video calls using a wifi connection.

Download Speed

Download speed is the rate at which data is transmitted from the internet to the computer. If you are browsing a new webpage, you are using download speed to view data on the internet.

Video calls need extremely good download speed to see crystal clear video of other people on the call.

Upload Speed

Most of the online activities use only download speed. But video calling requires good download and upload speed for an excellent video call. Upload speed is the rate at which data is transmitted from your computer to the internet. Basically, searching for a movie online or on your favourite OTT platform requires decent upload speed.

Video calls need very good upload speed to make sure your video and audio is crystal clear to others on the video stream.

Why video calls are better on wifi?

Now that we know what affects a video call, let’s understand why video calls are better with a wifi connection.

More bandwidth

Compare bandwidths provided by your mobile data and wifi connection. A daily data limit of 1.5 or 2 GB per day might offer you a speed less than 5 Mbps with mobile data. Whereas wifi plans offer internet speed starting from 30-40 Mbps.

A wifi connection has more bandwidth than a mobile data connection. Therefore, video calls are better on wifi.

Better speed

A good wifi bandwidth leads to better internet speed which in turn leads to better quality video calls.

Better upload and download speed

Most of the ISPs advertise their plans using their download speed. The upload speed offered is quite less than download speed even with a wifi internet connection. Mobile data has very low upload speed compared to a wifi.

Wrapping up

So, if you are casually browsing how to download twitter videos or watching a Netflix series, understand that these may load fine with mobile data. But, in case of a video call, go for a wifi connection for both good upload and download speed.
