LoRa / LPWAN is an exciting 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 narrowband modulation which has a much lower noise figure (-140dBm) than wideband systems like WiFi (-101dBm) so your signal can be received further away with the same power. Using unlicensed UHF spectrum (868/915MHz) you can setup a long range 15km link with less than a tenth of.a watt (20dBm).
CloudRF supports LoRa with a low receiver threshold of -140dBm, a dedicated sub-noise floor colour schema, hardware template for novice users and propagation models suitable for the UHF spectrum it uses. The high resolution LIDAR data enables you to plan in urban areas with a high degree of precision. For wide area plots there is 30m terrain data worldwide which includes clutter like buildings and vegetation.
You can load in some generic (EU) LoRa settings within the web interface by opening the hardware database (box icon) and searching LoRa.
