Question

WiFi uses how much frequency?
1) 2.2GHz
2) 3GHz
3) 3.5GHz
4) 2.4GHz

Answer 1

WiFi primarily operates on the 2.4 GHz and 5 GHz frequency bands, with 2.4 GHz being one of the common frequencies used by many wireless devices.

Step-by-step explanation:

WiFi operates on multiple frequencies, but the two primary bands are 2.4 GHz and 5 GHz. Various devices and protocols may use different channels within these bands to communicate. For instance, common household microwave ovens operate at a frequency of 2.45 GHz, which is very close to the 2.4 GHz band used by WiFi. This similarity in frequency can sometimes lead to interference between the devices. It is important to note that while 2.4 GHz is widely used, it is not the only frequency available for WiFi use.
Therefore, the correct answer to the question 'WiFi uses how much frequency?' is option 4, 2.4 GHz.
