Planning the #RustLang 2021 Edition

@Blort Depends on the region... #LoRa runs at 868 MHz in Europe, 923 MHz in Singapore.

Because it's running at a lower frequency than 2.4 GHz WiFi, the signals go farther.

But LoRa is a simple packet based protocol, it's not meant for chatty networks like WiFi.

@Blort LoRa / LoRaWAN is more suitable for battery-powered sensors on the streets and in the wild. (Because of its low power and long range)

Here's a good use case: Sensors for our garden...
