The authentication of the wireless “cable” concept is a common concern among users.
When they use the term “wireless USB cable,” they usually mean something like this:
- A USB over Wi-Fi bridge connects to a computer.
- This connection turns the USB output into a wireless signal.
- A secondary USB adapter on an attachable device receives this wireless signal.
The secondary bridge reconverts the wireless signal into a USB input and transfers this data to the attachable device.
Generally, it is the same USB wireless connection, but a few extra steps are required. In both scenarios, USB plugs communicate with another device—either a different piece of equipment or another USB plug—through Bluetooth signals.
Use Cases: Dongles or wireless USB cables are used in the following scenarios:
- Using a wireless document camera in a classroom to display images or objects in high resolution
- Connecting a USB webcam in a room wirelessly
