How does Wi-Fi technology work?
Wi-Fi technology works by using radio waves to transmit data between devices. The process begins with a device, such as a laptop or smartphone, which sends a request to a wireless router to connect to the internet. The router, which is typically connected to a physical internet connection, such as a cable or DSL line, then sends a signal back to the device, allowing it to connect to the network. Once connected, the device can send and receive data to and from the router, which forwards the data to its final destination on the internet.
The Wi-Fi signal is transmitted using a specific frequency band, typically 2.4 gigahertz (GHz) or 5 GHz. The signal is modulated, or varied, to encode the data being transmitted, and is then received by the device, which demodulates the signal to retrieve the original data. The range of a Wi-Fi signal can vary depending on the power of the transmitter, the sensitivity of the receiver, and the presence of obstacles, such as walls or other devices. To overcome these limitations, Wi-Fi networks often use multiple access points, which can provide coverage to a larger area and support more devices.
