So how are Bluetooth and Wi-Fi different?

The first is the familiar Wi-Fi, which is good at connecting multiple devices simultaneously. It has been created as a hub that connects to the Internet. The communication speed is breakneck, and it is good at mass data communication. However, because of its considerable power consumption, it is used for stationary devices such as routers that can supply power from outlets.

Bluetooth, on the other hand, is a technology designed for one-to-one communication. Both communication speed and communication distance are weaker than Wi-Fi, but they consume less power and can be used for long-term devices such as keyboards and mice. Since these devices have a small amount of data to be communicated at one time, data delay is unlikely to occur.
