What is a WiFi Extender and How Does it Work?
A WiFi extender, also known as a WiFi booster or WiFi repeater, is a device that amplifies the signal of an existing WiFi network to extend its coverage area. It works by receiving the WiFi signal from the router, amplifying it, and then rebroadcasting it to areas of the home or office where the signal is weak or non-existent. This allows devices to connect to the internet from a greater distance, eliminating dead spots and improving overall network performance.
The WiFi extender connects to the router wirelessly, using the same WiFi frequency band (2.4GHz or 5GHz) as the router. It then rebroadcasts the signal on the same frequency band, creating a new network with the same name (SSID) as the original network. Devices can connect to the extended network just like they would to the original network, without needing to reconfigure their WiFi settings.
Why Do I Need a WiFi Extender?
A WiFi extender is necessary for anyone who experiences weak or spotty WiFi coverage in their home or office. This can be due to a variety of factors, such as the size of the space, the number of physical barriers (walls, floors, etc.), and the presence of interference from other electronic devices. A WiFi extender can help to eliminate dead spots and provide a strong, reliable connection to the internet, even in areas that were previously out of range.
In addition to improving WiFi coverage, a WiFi extender can also help to improve network performance.
