LoRa coverage planning

LoRa / LPWAN is an exciting new communications technology for the Internet of Things (IoT) which lets you send small packets of data long distances with very little power.
It's key advantage is its unique modulation which allows it operate beneath the noise floor (about -110dBm) within unlicensed spectrum (868/915MHz) so you can setup a long range 15km link with less than a tenth of.a watt (20dBm).

The worst cell site in Scotland?

We've found a contender for the worst cell site in Scotland. Not because it's powered by a Diesel generator drinking at least 3 litres an hour or at the bottom of a narrow winding valley but because the valley is unpopulated - except for sheep.
We were amused to see the cell site had equi-distant panels, two of which were pointing directly into the dense forest either side of the narrow valley so we modelled the site using some 30m DSM and generic parameters (12m height, -100dBm receiver threshold) and the coverage results confirmed the obvious.
