There are also what you could call Wi-Fi-adjacent devices. These are devices that use radio waves very close to the traditional Wi-Fi spectrum, but aren’t considered Wi-Fi because they don’t connect to the internet the same way. A good example would be the Zigbee protocol, which was created for early low-power smart devices to communicate, and still exists in some forms today. Bluetooth is another example – it operates on the 2.4GHz frequency like Wi-Fi, but is used for connecting two short-range devices to each other. But doesn’t create a wider online network.

Wi-Fi extenders work like stereo amplifiers used for driving hi-fi systems. They use electric power from a power supply to increase the strength of the original wi-fi single in the air.
