What options exist for transmitting information (short text file) at a distance of 500-1000 meters, without using a cellular connection. I have experience in using dron (quadrocopters), where the communication range with smartphones when using Wifi 5 is guaranteed at least 1 km, in the absence of interference in the city 100-200 meters.

If you have a TCP/IP connection then transferring data is simple.

Thanks for the recommended links. Hopefully with their help I can solve the problem. I want to give advice when in the search I indicated my request "WiFi transmit ...." I was given other less interesting and useful links. But there were a lot of them. It may be possible to use sorting by the number of views when creating a list, so that the most interesting ones are at the beginning of the list.
