It's actually a pretty interesting and novel use of newest technology. I'm impressed.
Although the text itself reads like an Ad for Sigfox without explaining what it is. Maybe I've been living under a rock but I have no idea what it actually is.
If anybody is as curious as myself here you go:
> Sigfox uses 200 kHz of the publicly available and unlicensed bands to exchange radio messages over the air (868 to 869 MHz and 902 to 928 MHz depending on regions). Sigfox uses Ultra Narrow Band (UNB) technology combined with DBPSK and GFSK modulation.
