What is a WiFi repeater?
A WiFi repeater, also known as a range extender, is a device that receives the existing signal from your WiFi router and amplifies it. By doing this, it extends the coverage area of your WiFi network, allowing you to connect to the internet in areas of your home or office that may have previously experienced weak or no signal.
WiFi repeaters are particularly useful in larger spaces or environments with physical obstructions that impede the wireless signal, such as walls, furniture, or other objects. By placing a repeater in a strategic location, users can significantly improve their wireless connectivity experience.
How does a WiFi repeater work?
A WiFi repeater picks up the radio signals broadcasted by your router. When the repeater receives these signals, it boosts their strength and retransmits them, effectively extending the reach of your WiFi network. The repeater must be placed in a location where it can still receive a good signal from the router, as its performance depends on this initial connection.
Once the signals are boosted, the repeater creates a new network that devices can connect to, often with a similar network name (SSID). Some repeaters also offer a feature to differentiate between the main network and the extended network. This way, devices can switch seamlessly between the two signals depending on the location within the coverage area.
What are the benefits of using a WiFi repeater?
