You are setting up a smart home where devices like lights, cameras, and door locks can be controlled from a smartphone. Which wireless technology would you use?

Question

Accepted Answer

Wi-Fi would be used. Wi-Fi allows smart home devices such as lights, cameras, and door locks to connect wirelessly to a home network and be controlled remotely from a smartphone through the internet, without needing cables between the devices and the router. (Bluetooth can also be used for very short-range direct control of individual smart devices.)
