I was hoping for something like this but unfortunately LoRa seems pretty meh if you don't have line of sight between the devices or maybe open enough areas that don't drown the signals. I was hoping that it could go for a couple hundred meters in urban areas (was trying this out in the outer London zones, UK) but the results were pretty bad. Reception was spotty the moment direct LOS was lost and non existent ~10m after that. Not even worth mentioning the results if one of the nodes was inside a building.
If anyone had any success in dense areas I'd really appreciate any links to the hardware/antennas/firmware/software you used to get good results.
- slothtrop 6y agoAh I see. Got too excited.
- bigiain 6y agoAntennas and height make a huge difference. I’ve got a hop from my place to a friend that’s a little over 3km non line of sight (terrain/hill between). Can’t do that with the stock rubber ducky antennas, but with a swr meter tuned home made dipole antenna on a 4m pole on my roof it’s rock solid (using 433MHz, not sure if 815/915 would get that far).
- geoah 6y agounfortunately that raises the entry level by quite a bit but definitely worth a shot. I need to check about the band, cause most of the LoRA I saw being sold in the UK are 868/815, but a cursory google search says that 433 might be allowed. Will take another look thank you.
