I mean yeah, it’s a higher frequency than wifi. WiFi uses light already, we just don’t see those frequencies. Cell towers and routers are just big lighthouses. The benefit of lower frequencies is that most building materials are transparent to them so we can get internet in rooms other than the router room.
