You are designing a wireless network for an office building. The building has a large number of tenants who utilize wireless already. Which protocol will least likely overlap with wireless channels the tenants are currently using?

The 802.11ac protocol will be least likely to overlap the wireless channels the tenants are using. The 802.11ac protocol uses the 5 GHz wireless frequency spectrum. The 5 GHz spectrum defines 24 nonoverlapping wireless channels. The 2.4 GHz spectrum defines 11 channels, but only 3 of them are nonoverlapping. Although 802.11n operates on 2.4 GHz and 5 GHz, 802.11ac only operates on 5 GHz. Therefore, 802.11ac will have the least likely overlap of current channels. 802.11b and 802.11g operate solely on the 2.4 GHz spectrum.
