So, I have this idea for a sensor but I’m struggling with which data-transfer technology would be most feasible for my case: * around 20k sensors * battery powered * for urban area * around 100 outgoing packages per day per sensor * packages must contain at least data with sensor ID, battery data and sensor data * ability to detect and connect to closest gateway automatically
I believe NB-IoT is the most straight-forward solution but its expensive.
LoRaWAN looks like a good alternative, but I’m not sure about package sizes…
Is bluetooth5 mesh or OpenThread applicable?
Any thoughts, links, discussions would be much appriciated. Thanks in advance.
