Chatting is happening through Bluetooth at Jantar Mantar, the new ‘digital weapon’ of the protesters

New Delhi: Have you ever thought that messages can be sent from one phone to another even without any mobile network, Wi-Fi connection or mobile data? In the era of modern technology, this is no longer just a fantasy. New apps like ‘Bitchat’ which came into discussion recently are bringing a revolution in this direction. This Bluetooth-based messaging technology is emerging as a new and secure option to keep people connected even without internet coverage.

The journey of digital messaging started with SMS

Mobile messaging started in the year 1992, when the world’s first test SMS ‘Merry Christmas. Was sent. At that time, only limited messages of 160 characters could be sent, but this technology laid a strong foundation for future digital communication. Later came the era of advanced apps like WhatsApp, Telegram and WeChat, which provided modern features like photos, videos, voice notes and group chat. However, the biggest limitation of all these traditional platforms is that they require active internet and central server to run.

How does Bluetooth mesh networking work?

Now technology has entered a new era. Be it the Bitchat app recently introduced by X co-founder Jack Dorsey or other platforms like Bridgefy, Briar and Jott, all of them work on Bluetooth Mesh Networking technology. In this system, two or more smartphones are directly connected to each other through Bluetooth. For its operation neither any SIM card nor creation of user account is required. In this, the message reaches directly from one device to another instead of going to a third server.

Lifesavers will be built in disaster and no-network zones

Bluetooth messaging technology proves to be extremely helpful in situations where the mobile network comes to a complete halt. When telecom towers collapse during natural disasters like earthquakes or floods. Large music concerts, sports stadiums, or in remote mountainous areas and forests where network signals are extremely weak. Many times, in emergency situations, when internet services are stopped in a particular area, this technology is still capable of sending messages at the local level.
