Why calls require internet connection to be turned off

In today’s digital age, staying connected is an essential part of our lives. We rely heavily on the internet for various activities, including communication. With the advent of VoIP services and messaging apps, making calls through the internet has become increasingly popular. However, have you ever wondered why calls require an internet connection to be turned off? Let’s delve into the reasons behind this requirement.

First and foremost, when making traditional phone calls, the communication takes place through the Public Switched Telephone Network (PSTN). PSTN relies on physical copper wires and analog signals to transmit voice data. It operates independently of the internet, ensuring stable and reliable communication even during internet outages or network congestion. This infrastructure has been in place for decades and is known for its robustness.

On the other hand, voice calls conducted over the internet, also known as Voice over IP (VoIP), utilize the internet network to transmit voice data as packets. These packets are sent and received through the internet protocol, which allows for greater flexibility, cost-effectiveness, and additional features compared to traditional calls. However, they also introduce a new set of challenges related to network quality and stability.

One critical aspect of internet-based calls is bandwidth availability. Bandwidth refers to the maximum rate at which data can be transmitted over a network. When you’re making a VoIP call, it requires a certain amount of bandwidth to maintain voice quality and avoid audio lag or drops. However, if you have multiple applications or devices using the internet simultaneously, they will compete for available bandwidth, potentially degrading the call quality.

Thus, turning off the internet connection during a call helps prioritize the available bandwidth exclusively for the call. By eliminating unnecessary internet traffic from other applications or devices, the call’s quality and stability can be ensured. This becomes particularly important when the internet connection has a limited bandwidth, such as in rural or remote areas, where internet infrastructure might not be as advanced as in urban areas.

Another reason to turn off the internet connection during a call is to minimize packet loss and latency. Packet loss occurs when the data packets carrying voice information are dropped or lost during transmission due to network congestion or errors. Latency, on the other hand, refers to the delay between a sender transmitting a packet and the receiver receiving it. Both packet loss and latency can significantly degrade call quality, leading to garbled or delayed audio.

To mitigate packet loss and latency, it is necessary to optimize the call’s network path. When your internet connection is turned off during a call, it reduces the chances of encountering congested routers or network bottlenecks that could disrupt the transmission. It allows for a more direct and reliable connection to the call recipient, resulting in improved voice quality and reduced audio delays.

Lastly, turning off the internet connection during a call also offers privacy and security benefits. VoIP calls transmitted through the internet can be vulnerable to eavesdropping or unauthorized access if the network connection is not secured adequately. By disconnecting from the internet, you eliminate potential risks associated with online communication. This is particularly relevant for sensitive or confidential conversations where privacy is of utmost importance.

In conclusion, calls requiring the internet connection to be turned off serve multiple purposes. They help preserve available bandwidth, ensuring better voice quality and stability. By minimizing packet loss and latency, the call experience becomes more seamless and natural. Moreover, disconnecting from the internet enhances privacy and security, shielding calls from potential eavesdropping or unauthorized access. While the internet has revolutionized communication, understanding when and why to turn off the internet connection during calls is crucial to optimize the overall calling experience.
