Is it true that modern Wi-Fi networks use frequency hopping to avoid interference?
Unclear. Several peer-reviewed sources describe Wi-Fi as a fixed-channel technology that interferes with hopping systems such as Bluetooth and ZigBee, and one describes Wi-Fi nodes using fixed frequency separation rather than hopping. None directly states whether modern Wi-Fi standards employ frequency hopping, so the evidence only partially bears on the claim.
