A "wireless" USB extender......?
Physical USB cables are limited to 15 feet (5 meters).
Bluetooth is used for wireless connectivity: e.g., a mouse and keyboard. But there are other wireless Keyboard and Mouse products that do not use Bluetooth. They also use a transmitter/receiver that is connected to a USB port. The transmitter/receiver communicates with the keyboard and mouse - both battery powered and no wires.
Range is limited.....
Microsoft, Logitech, and other manufacturers offer various products for wireless peripherals.
