Make some noise for net-neutrality - Transfer data over Spotify
The app, which decodes the sound into data, is built around the Quiet library (https://github.com/quiet/org.quietmodem.Quiet). The JavaScript version of this library is used for encoding data to sound. This library works in a very similar way as old broadband modems. Such a modem converts (modulates) a digital signal into analog audio, and converts (demodulates) an analog signal into digital data. This way, computers were able to communicate over telephone lines using hisses and crackles.

Camera + LTE
Hi, LoRa has acceptable use which limits it to around 30k/day so not possible. The LTE option is a good idea, check with your mobile signal strength at the desired spot. To get it lasting you could use a rechargeable LiPo battery which should be good for 5000 recharges. A small solar panel will easily keep it topped up, especially if it’s sending one pic/day. You want to find an esp32 LTE board with good sleep stats. These may help https://randomnerdtutorials.com/power-esp32-esp8266-solar-panels-battery-level-monitoring/ with regard to connecting a remote camera, you may find it easier the other way round. Get esp32-cam board, then find a LTE modem. https://github.com/olliiiver/esp_lte_modem
