Why aren't modern SoC modems just support all bands? How hard is it?

Why aren't modern SoC modems just support all bands? How hard is it?
- microtonal 7mo agoJust a guess: maybe it requires fairly expensive certification that is not worth it when a SoC family is barely used in a region (yes, I know, chicken-egg).
- karteum 7mo agoIt's not only the issue of SoC modems but about the whole integration (RFIC, LNA/PA, RF switches, antennas...). The more bands you integrate, the more difficult it becomes (or with compromises such as worse performance because of wideband antennas...). If I may risk a comparison : you can't have a lense with a huge focal range that would simultaneously be perfectly sharp and have a wide aperture like fixed focals...
