In the era of digital communication, the way we make phone calls has undergone a significant transformation. With the advent of Wi-Fi calling, users can now make voice calls over the internet, eliminating the need for traditional cellular networks. But what exactly is the difference between regular calling and Wi-Fi calling? In this article, we will delve into the world of voice over internet protocol (VoIP) and explore the key differences between these two calling methods.
Introduction to Regular Calling
Regular calling, also known as cellular calling, uses cellular networks to connect calls. When you make a call using your mobile phone, it sends a signal to the nearest cell tower, which then connects you to the recipient’s phone. This process relies on the availability of cellular coverage, and the quality of the call depends on the strength of the signal. Cellular calling is the traditional method of making phone calls and is widely used across the globe. However, it has its limitations, such as poor coverage in rural areas, dropped calls, and high roaming charges.
How Regular Calling Works
The process of regular calling involves several steps:
The caller initiates a call by dialing the recipient’s phone number.
The call is sent to the nearest cell tower, which forwards it to the mobile switching center (MSC).
The MSC connects the call to the recipient’s phone, and the call is established.
The call is then maintained through the cellular network until it is terminated.
Introduction to Wi-Fi Calling
Wi-Fi calling, on the other hand, uses the internet to connect calls. When you make a call using Wi-Fi calling, your phone sends the call over the internet to the recipient’s phone, using their internet connection. Wi-Fi calling is a type of voice over internet protocol (VoIP) technology that allows users to make voice calls over the internet. This method of calling has gained popularity in recent years, especially among users who experience poor cellular coverage or want to save on roaming charges.
How Wi-Fi Calling Works
The process of Wi-Fi calling involves the following steps:
The caller initiates a call by dialing the recipient’s phone number.
