For IoT products, the interoperability question depends on the communications protocol you use, since most products can’t communicate with systems using a different protocol. The protocol you choose will also affect your hardware. For example, transmission distance will determine your available IoT modules, power requirements, and shape the network configuration for your system. There are a huge number of protocols to choose from. New versions are coming out every year, and groups are trying to consolidate the options that already exist. How do you decide which one is right for your product?
