NB-IoT

Has anyone experience with the NB-IoT systems?

Does such a device communicate directly (through mobile network) to another such device?

For example this device has RS-232 and RS-485 support. Will the date be sent to another such device or do I need a server to relay the data? I need to connect two points that have no Line-of-sight connection, so mobile network is one good solution.

As far as I understand it, it's just like GPRS.... You need sim, server to connect etc...
Difference to GPRS is just bandwith, power etc.

Thanks. That's what I thought too.

But whatever info I found was not describing the basics of the operation.
