Andreas Spiess explains the principles of LoRa and LoRaWAN, covering link budget, bandwidth, and demonstrating how to send a message to The Things Network.
In this video, I show you the basic principles of LoRa and LoRaWAN, its plusses and minuses, and also show you my own LoRa gateway and a LoRa client, and send the first message to the things network. Link budget and bandwidth are introduced. This technology can be used for Arduino and other microcontrollers like the ESP8266 or the ESP32. It is LPWAN technology.

On “New LoRa RF distance record: 1336 km / 830 mi”
A good explanation of LoRa, and in particular of the "link budget" idea which makes LoRa different from other wireless tech: link to this video

On “Timeliness without datagrams using QUIC”
3) Certified firmware* * the telecom can and does blacklist IMEI numbers for unsigned firmware * it is illegal to fix bugs that cause eSIM hardware lock-ups * You can catch g05t5 on the carrier VPN network sandbox hitting each client Sometimes it is better to wipe the slate clean, and start again... LoRAWAN certainly does make sense in some use-case applications. link to this video
