It would be great if you could do voice via LoRa too but that would probably quickly exceed the duty cycle restriction.

- fsiefken 5y agoit could be done with codec2, but duty cycle of 1% would limit it to push to talk brief sentences every minute or so, it might be better to stick to text. Perhaps handy when someone had a mountain accident and can only push and talk. Use a speech to text decoder and limit expressions to 140 characters, should be enough for every piece of conversation including this comment (with vowels stripped out). o wait, that's to little - make it 300 characters.
- bri3d 5y agoYou can channel hop LoRa to massively increase the practicable duty cycle. I think voice could be in the realm of possibility.
- retzkek 5y agoIt would be interesting to see if you could incorporate a radio module like a DRA818U/V [1] and provide short-distance voice over MURS (VHF), FRS/GMRS (UHF), or similar bands. [1] http://dorji.com/products.php?CateId=14 http://dorji.com/products.php?CateId=14
