LoRa is short for Long Range. It's basically about providing a physical layer for networks over radio using spread spectrum modulation. It's got long range, even for fairly low-power devices, but also low bandwidth. Think IoT stuff. LoRaWAN is a layer above in the network stack (MAC) and runs on top of LoRa.
TNC is "terminal node controller". They're kinda sorta like modems for radios. KISS TNC is a particular protocol for communication between a radio and a TNC.
Shopping is a major one, I've found so many useful things from TikTok that no other platform has successfully been able to show me. It's also superior for viral growth and easily marketing new services in pretty much every way.
