Basic LoRA can do >7km in the 25mW ranges, but the bandwidth is minimal. Note, under some situations the range can hit hundreds of km.
CB/11meter range depends on many parameters, but even at 4W you would be lucky to reach beyond 80km.
The main difference is Lora Gateways receiver sensitivity is <-139dBm, and can recover data from what looks like the noise floor in most hardware.
If Lora had at least 3 manufacturers, I would have stuck it in every station years ago.

- ale42 2y agoThere are some amateur radio operators who operate in QRP (max. 5 W power) and have a DXCC award (so they have contacted at least 100 different countries). So the range is much more than 80 km, especially if you use digital modes able to recover signals you can't even hear (like FT8 or WSPR)... but bandwidth will be very low.
- Joel_Mckay 2y agoTropospheric ducting is rare on 11meter, but indeed Hams have achieved some pretty creative antenna setups in HF. It is a deep rabbit hole, but in the spirit of comparing apples-to-apples... Also, the ERP limits on FCC stamped consumer modules is fairly low for unlicensed users. i.e. many Lora modules have iffy certified antennas for compliance reasons. Cheers, =3
