A Wi-Fi range extender, also known as a Wi-Fi repeater or a signal booster, is a device that helps extend the coverage area of your wireless network. It’s used when you have areas in your home or office where the Wi-Fi signal is weak or non-existent.
Here’s how a Wi-Fi Range Extender typically works:
A Wi-Fi range extender works by receiving the existing Wi-Fi signal from your wireless router, amplifying it, and rebroadcasting it to extend the coverage area. Here’s a breakdown of how it functions.
- Signal Reception: The range extender picks up the Wi-Fi signal transmitted by your router. It acts as a receiver, capturing the signal and processing it to prepare for rebroadcasting.
- Amplification: Once the range extender receives the Wi-Fi signal, it boosts or amplifies the signal strength. This amplification helps overcome signal degradation and interference that may occur as the signal travels through obstacles like walls, furniture, or long distances.
- Signal Rebroadcasting: After amplifying the signal, the range extender rebroadcasts it as a new Wi-Fi network. It creates a secondary network with the same name (SSID) as your existing network, but usually with an appended identifier to differentiate it (e.g., “MyNetwork_Ext”). This extended network can cover areas that were previously out of range or had weak signal reception.
- Connection to Devices: Devices within the range of the extended network can connect to it, just like they would connect to your main Wi-Fi network. Users can select the extended network from the available networks listed on their devices and enter the Wi-Fi password, which is typically the same as the original network. The range extender acts as a bridge between the connected devices and the router, facilitating communication between them.
- Seamless Roaming (Mesh Systems): In mesh Wi-Fi systems, multiple range extenders or access points work together to create a unified network. These systems have intelligent roaming capabilities, allowing devices to seamlessly transition between the main router and the extenders without manual network switching. This ensures a consistent connection as users move around the coverage area.
It’s important to note that using a Wi-Fi range extender may introduce some signal degradation due to the additional hop in the network. The extended network’s performance and speed may not match that of the original network directly connected to the router. Factors like the distance between the range extender and the router, the quality of the extender itself, and the number of devices connected to the network can impact the overall performance.
To achieve the best results with a Wi-Fi range extender, proper placement is crucial. Finding an optimal location where the range extender can receive a strong signal from the router and provide extended coverage to the desired area is essential for optimal performance.
