Hybrid IoT communications could be the best option
In fact, the company, which provides Low Power Wide Area (LPWA)
networks, says one could use a hybrid that includes an unlicensed LPWA
network along with a licensed, cellular LTE narrowband IoT (NB-IoT) or
LTE Cat M1 network solution instead. That way you can support cheap,
unlicensed IoT short messaging close up, as is offered by Sigfox and
others, and then offload the sensor traffic to more expensive, licensed
LTE cellular mobile networks as the devices move off home base, such as
what happens in asset tracking, Sigfox says.
Firewalls are becoming increasingly important in today’s world. Hackers and automated scripts are constantly trying to invade your system and use it for Bitcoin mining, botnets or other things.
