Which of the following best explains why client devices connected to a 5 GHz Wi-Fi access point usually experience less radio-frequency (RF) interference than devices connected to a 2.4 GHz access point?
5 GHz signals have longer wavelengths that bend around obstacles, preventing interference.
The 5 GHz band uses frequency-hopping spread spectrum, whereas the 2.4 GHz band uses direct-sequence spread spectrum, eliminating interference.
Regulatory power limits are significantly higher in the 5 GHz band, so stronger signals overpower any interference.
The 5 GHz band offers many more non-overlapping channels and is shared with far fewer common household devices.
The 5 GHz band provides far more non-overlapping 20 MHz channels (approximately 24-25) and is not shared by common household devices such as microwave ovens, Bluetooth peripherals, cordless phones, and baby monitors that crowd the 2.4 GHz ISM band. This wider, less-congested spectrum greatly reduces co-channel and adjacent-channel interference, so users on 5 GHz networks typically see cleaner signals.
