I disagree that there is a fundamental incompatability issue with private networks. LoRaWAN is simply an over the air protocol for secure end to end encryption and end-device radio management. Nothing mandates the network infrastructure model.
One model is the central network server where all gateways at as a single virtual antenna.
It is not impossible to run the network server at the edge and provide a scalable solution for cloud computing. There are trade-offs that make it more complicated than a centralized model. That will be the case for nearly all fog computing. How do you handle shared session state at the edge?
Isn’t this in line with packet broker and private TTN?
The other trade-off is regarding ISM medium access. Seperated networks will create more RF traffic so wide area private networks in the open will create more traffic. However, adding end devices in any area creates more traffic regardless of network affiliation, it just does not fit the business model for some companies.
In this case the TTN model is not compatible with fog computing but the TTI private network is?
