What is WiFi and how does it work?
WiFi is a type of wireless networking technology that allows devices to connect to the internet or communicate with each other without the use of cables or wires. It works by transmitting data through radio waves at a specific frequency, typically in the 2.4 gigahertz or 5 gigahertz range. This allows devices to communicate with each other and with routers, which are connected to the internet, to access online content.
The WiFi protocol uses a variety of technologies, including spread spectrum, frequency hopping, and packet switching, to enable reliable and efficient data transfer. When a device is connected to a WiFi network, it sends and receives data packets to and from the router, which forwards the packets to their final destination on the internet. WiFi technology has become ubiquitous, and is used in everything from smartphones and laptops to smart home devices and industrial equipment.
Who invented WiFi?
