Too bad the hardware for this is eyewateringly expensive :'(

For those interested in a more accessible LTE meta-data decoder check out https://github.com/JiaoXianjun/LTE-Cell-Scanner which can work with even cheap rtl-sdr dongles (for some things). It is a fork of an older https://github.com/Evrytania/LTE-Cell-Scanner

Huh how can that work? It's only got 2Mhz bandwidth. An LTE cell is much wider.

Possibly it's decoding MIB only, which is only 1.080 MHz wide.
