BrainChip Demonstrates Smart Automotive, page-95

Yea it sort of explains how it will be used but not quite. The term IoT is quite broad so correct me if I'm wrong here but I think this could include Smart Home, Automotive or others. And sensor analysis is quite broad too.
For example it could be for fridge smell sensor analysis.
It could also be keyword spotting in an Amazon Alexa equivalent, or in an automotive application.
The most important things to consider is that 2 nodes will result in the maximum latency so speed must be acceptable, though at the same time power consumption is lowest too. So battery or power constrained applications make the most sense.
It would almost definitely be too slow for image analysis, I think audio, smell or possibly even tactile applications make the most sense.
That said, while you maybe wouldnt call it an IOT application, it's probably even fine for Covid analysis because the longest time is spent cleaning the device for the next person to use. If it's for using in remote places battery life is more important.
