Flipper is about to launch a LoRa module for wirelessly sending Bitcoin transactions

According to Bitcoin News, Flipper's upcoming LoRa module can send messages through a radio relay network without relying on the internet. In tests conducted in London, messages were transmitted over 150 kilometers via the MeshCore network.

This technology can be used to send Bitcoin transactions: signed Bitcoin transaction data can be transmitted via LoRa radio and relayed to a gateway connected to Bitcoin nodes, which then broadcasts it to the network. When local internet connections are interrupted, users can send transactions in this way.
