Every LoRa article I've read always does range tests but never mentions bitrate achieved at that range. I have tried to find a good idea of what the rates are, and I've seen everything from a few hundred kbps in short range to literal bits-per-second for longer range and no good guidance for what is actually typical.
I'd like to see if two LoRa modules could be used as a transparent bridge for a 9600 bps serial connection over about 5km with good line of sight with a moderate sized whip antenna. It seems like 1-2km at that rate is for sure but determining the bitrate falloff vs distance (as it automatically adjusts the rate for the signal) I haven't found a resource for.
- Havoc 4y agoAnother comment in this thread says "Best case you're getting a few kbps," So yeah good for sensors
- yardie 4y agoMy experience is it depends. I’m getting ~50kbps at 500m over water. I’m also using it in a mesh so don’t need more than that. With a stub antenna.
- johnwalkr 4y agoThey also rarely give error rate. Having used lora my gut feeling is you’re not going to get more than 3km unless you take advantage of hills or towers. Use the keyword “fresnel zone” for more information. Also Lora is one-directional. It’s not even half-duplex out of the box. So you either need 2 sets of radios or you need to implement half-duplex communication in software.
