A common thing I see is people running these part-15 (in the US) devices with upgraded antenna systems, which isn’t permitted. Either run it under amateur rules or under part 15.
LoRa & LoRaWAN are next-generation technologies that will support wireless connectivity in IoT, alongside 5G RF Technologies. Uniquely enabling long-range, low-power communication, they are already being used in numerous consumer and industrial applications to solve real-world problems.
