Question 12

A customer wants to connect a Bluetooth keyboard and mouse to their tablet for a presentation. They ask which accessory is needed to ensure both devices work reliably from across the room. What should you recommend?

Accepted Answer

A Bluetooth extender or repeater to boost signal strength.. A Bluetooth adapter is not needed if the tablet already has Bluetooth, but a Bluetooth extender or a USB hub with Bluetooth can improve range. However, the most straightforward answer is that a Bluetooth adapter (if the tablet lacks built-in Bluetooth) is essential, but since most tablets have it, a simple Bluetooth keyboard and mouse set will work. The correct answer here is that a Bluetooth adapter is not required; the tablet's built-in Bluetooth is sufficient, but for range, a Bluetooth extender can help.
