Building Your Own 4G LTE Base Station
Get your hardware ready and strap in, as [MaFrance351] guides you through setting up your own base station, with extreme amounts of detail outlining anything you could get
There's plenty of fun things you could achieve with such a base station: reverse-engineering of proprietary technology, security research, and probing for vulnerabilities through WWAN interfaces rarely considered as an attack surface. Maybe you could even set up your own cell network — if you ever go sailing in neutral waters, that is.
These receivers could be in drones, agricultural machinery, autonomous vehicles, or survey equipment. The base station receives signals from GPS and other satellite systems such as GLONASS, Galileo, or BeiDou. It then calculates differential corrections based on its known location.
To reduce costs, DIY RTK base stations may use lower-end receivers and antennas, which significantly compromises performance, especially in critical conditions like urban canyons or areas with dense tree cover.
A GNSS Base Station can also be created using a SBC (single board computer). Thanks to originaldev on the SparkFun forums for creating a Raspberry Pi based setup. You can checkout their build instructions here. Deploy! That's it!
