I’ve recently opened a thread about small-sized LoRa modules for under water communication:
I haven’t completely dropped the idea of using VHF and UHF bands to bridge a couple of meters in water but I’d like to emphasize here again that VHF/UHF radio modules and under water communication is not a good match.
Anyways, on my search or lower frequency modules I came across this series from hoperf:
The model number RFM98PW-169S2 supports 169MHz at 27dBm.
Has anyone of you experience with these modules and in particular what gateways can be used for those?
Thank you guys!
