Maximum Coupling Loss vs Link Budget

Hi everyone,

Sorry if this post is a bit off topic. I’ve been using LoRa in the past, and now I’m exploring the possibilities of NB IoT using the Sodaq NB IoT Bee. Now I’m trying to compare the coverage level of the two technologies. LoRa uses Link Budget for this figure, while NB IoT uses Maximum Coupling Loss. Now from what I can see Link Budget as used with LoRa is similar to Maxlmum Coupling Loss for NB IoT, but is it? I find it rather confusing. Can someone shed some light on the difference between these terms? Thanks!
