But because, unlike with ethernet, the spectrum is shared by every single device on your network and even those on other people's networks, you won't actually be seeing gigabit speeds. Gigabit ethernet is still faster, even though 160MHz WiFi-AC technically has more bandwidth under the best of conditions.
