The FCC is reading “router” pretty broadly here, and that now includes portable Wi‑Fi hotspots, while phones that can share a connection are still treated separately.
Wild how “router” suddenly means “anything that shares wifi” but your phone doing the exact same thing gets a hall pass. feels like they’re regulating the form factor, not the actual behavior.
The “phone gets a hall pass” part might just be the FCC carving out licensed cellular devices vs. unlicensed Wi‑Fi gear, even if the behavior looks identical from the user side.
