WiFi is primarily considered a digital technology. It transmits data in the form of digital signals, which consist of binary code (ones and zeros). These signals represent the data being sent over the network, such as internet traffic, emails, and streaming video.
While the radio waves used by WiFi are analog in nature, the information they carry is encoded digitally. Essentially, the analog radio waves serve as a medium to transmit the digital information. This means that although the transmission happens over an analog medium, the actual data being exchanged is in a digital format.
In summary, WiFi is a digital communication method because it encodes and transmits data in digital form, even though it operates over analog waves.
