In my industry we use copper wires (Wholesale Line Rental - WLR) to communicate with monitoring kit and to adjust gas pressures.

We are preparing for all these lines to be withdrawn by 2025 and to be replaced with Mobile Data/Solar power/Batteries (we used the power in the lines for modems etc)

Its too expensive to get fibre (and power) installed at thousands of sites

What's your mobile data solution? Are you going LPWAN (ZigBee, LoRa, Sigfox) or LTE?

'Standard' Mobile GSM I think. Sites are scattered far and wide. They don't communicate to each other but to a central hub which records pressures and readings and sends setting instructions.

Edit, so LTE then

Thanks. That's interesting. I'm rolling out a similar setup on a project that runs mostly on solar, because of which the power budget is relatively tight. We've also opted to run LTE (mostly because we need more bursty bandwidth for remote maintenance). The total power budget under 5 watts. The LTE modem uses a smidge over 0.7W on average.

I don't know the engineering specs (I'm the accountant) but looks like a Cello modem and technolog solar panel. Good Luck with your project.

Thanks and likewise good luck with your project
