Delhi NEET Protests: Bluetooth Mesh Apps Enable Communication Without Internet

During protests in Delhi over the NEET-UG paper leak, internet services were shut down in some areas.

To stay connected, protesters used special apps like Bridgefy, Briar, and Bitchat.

These apps use Bluetooth technology to send messages directly between nearby phones, even without internet or mobile data.

Each phone acts like a small relay station, passing messages from one to another.

This way, people can communicate even when the internet is not available.

However, these apps work best when many people are using them in the same area.

If too few people are using the app or they are too far apart, the messages may not get through.
