@lupyuen is there a rss feed for your articles somewhere? would be really nice to have :)

Chirp in real-time action ... 64-byte LoRa packet ... Transmitted by Hope RF96 connected to ... At 923 MHz with 125 kHz bandwidth ... Captured by with R2 SDR

@Blort Depends on the region... 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.

More about this...

@lupyuen
Ok, that is cool. Thanks for explaining it to me. Does it still run in a similar frequency range to wifi, ie 2.4-5.6ghz? I'm just thinking about if using it could also reduce interference with wifi devices...

@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...
