SOME/IP is an automotive protocol used for communication between vehicle ECUs. It is an application layer protocol, used in automotive ethernet.

Communication is necessary between between sensors, actuators and control units within a vehicle. These were acheived by using CAN bus. With advancement in technology, automotive systems needed mechanism for transfering large amounts of data for applications like camera based driver assistance systems, in-vehicle entertainment, software upgrades, etc. CAN bus was primarily designed for low bandwidth applications and hence these new requirements could not be accommodated with CAN.

LoRaWAN on the other hand, is a wireless communication protocol, built on top of LoRa physical layer and designed for long-range, low-power applications such as Internet of Things (IoT) devices. LoRaWAN support 3 different operating modes: Class A, Class B, and Class C. The operating modes determines the communication behavior and power consumption characteristics of LoRaWAN devices.
