A WiFi signal transmits and receives information between your your electronic device and router to connect to the internet. WiFi, short for wireless fidelity, refers to a signal which operated at a few different frequencies.

Generally speaking WiFi is typically used as a standalone term. The term microwave is a reference to a class of waves, referenced as a microwave range or spectrum of frequencies that the WiFi signal operates. For example, the WiFi signal from your laptop is often transmitted at 2.4 GHz, a frequency found within the microwave range, or spectrum of 300 MHz to 300 GHz. This 2.4 GHz frequency is also within the same spectrum of what is called the Radio Frequency (RF) range, 3 KHz – 300 GHz. As you may notice, the RF is simply a slightly more broad frequency spectrum than the microwave range. All of the terms are often used interchangeably.
