LoRa versus FSK modulation signal spectrum

LoRa modulation has some advantages. Like superb receiver sensitivity and immunity to interference. Has some problems, true, but at the end, it's a great way to send small packets of data to long ranges using low power.

Anyhow, today only one picture: how LoRa spectrum compares to FSK signal spectrum? Like this:

LoRa modulation vs FSK modulation

Those two peaks are nearby FSK stations, while plateau is 250kHz wide LoRa signal. Difference is at least clearly visible šŸ˜‰
