> ...are not making use of light through air, and your wireless network connection cannot make use of light through air even a fraction as efficiently as light through fiber optic cable...

There's a clear misunderstanding here.

Light and wireless signals used by mice etc are the same thing though, just at a different frequency. They propagate at the same speed, the speed of light, which ironically is slower in glass.

Wireless signals in air travel faster than light in a fiber optic cable (and faster than electricity in copper).
