FireChat creates a mesh network using Bluetooth and peer-to-peer WiFi. FireChat transmits messages and pictures offline between devices that are located within 200 feet of one another.
Thanks to FireChat’s innovative multi-hop and store-and-forward capabilities, FireChat users form a network that increases in size with the number of devices. It allows messages to hop from one device to the next in order to reach the recipient(s). This is why the more people use FireChat, the better and the larger the network becomes (unlike with cellular networks).
On the mesh network, messages are transmitted seamlessly from one device to the next in order to reach the recipient(s). When an Internet connection or cellular network is available, FireChat uses them to reach remote recipients.
Public messages are visible by anyone. Private messages are encrypted and can only be seen and read by the sender and the recipient.
