I was looking into longer range LoRa antennas and they are cheap, really. AliExpress has some for £3-£5. Even a large, 110cm 8dbi antenna can be had for £18. You can get decent range out of those, especially if you have direct line of sight. The simpler, 2dbi antennas do look a bit like WiFi antennas, but they are for a different wavelength.

As far as I know LoRa has some VERY low bandwidth (250bit/s - 11kbit/s) and there are some regulations at least here in germany that you may only use 1% of the capacity.
1% means that you may only send one second out of hundred. LoRa is mainly for sending short GPS positions or some other sensor data.
I did my research because I wanted to use LoRa for the next ROOPHLOCH challenge, but it seems it's too low bandwidth even for gemini.
I did it in python with the ignition and meshtastic librairies, i build a simple gateway who split the gemini page in smaller messages (200 characters) because of limitation.
I configure lora device at mediumfast (3.5 kbps). Take somes time to transfert but feasable. I did it without a gopher client and also without optimisation, just a proof of concept. Need a lot more test in different environment and need gemini capsule with less text by page.
I'm working on it !!!!!!
Cotteux, very interesting!
what limitation do you mean: speed? size? why do you need to split the page to 200 byte pieces?
The meshtastic protocol is limited to 230 characters to send and receive a message. I also made some test at longfast and it's working good. A small page take around 30 to 120 secondes without optimisation.
Gemini over LoRaWAN? — I'm fascinated by the idea of running a smolweb over LoRaWAN. Imagine a decentralized network of FLOSS-hardware devices, solar-powered, each running a gemini capsule and a relay (HAM radio style) to transmit data on to other points on the LoRaWAN mesh network. It's not a fast way to communicate, but smolweb gemini doesn't need to be. If LoRaWAN can reach 56.6kbps, it'd feel like the days of dialup, but... decentralized, solar-powered, and resistant to censorship. Has...
