What Is the Difference Between a WiFi Booster vs WiFi Extender?

[Internet Incharge]

I’m planning to improve the WiFi coverage in my home, but I keep seeing the terms WiFi Booster vs WiFi Extender used interchangeably. Some websites say they’re the same device, while others suggest there are important differences. I’d like to know whether a WiFi booster simply strengthens the signal or if a WiFi extender creates a wider coverage area by rebroadcasting the existing network. Has anyone compared both options in real-world use, and which one worked better for you?
