LoRaWAN roaming for overlapping networks

LoRaWAN has a feature called "macro-diversity", which allows more than one GW to demodulate the same uplink frame (UL). Multiple gateways receiving the same UL increases network resiliency ...

LoRaWAN backhaul overheads over satellite or cellular

This will probably depend on the protocol used for the backhaul. I have never looked into the details, but I most definitely wouldn't be surprised if some were a lot chattier than others. Taking the ...

What are the datarate and ADR best practices for moving objects

LoRaWAN's ADR has a relative long convergence time, because the network server needs to collect data (SNR, packet error rate, etc.) from several uplink messages before it could calculate the ideal ...
