Bluetooth is an example of which type of wireless technology?

• A. Uses radio waves
• B. Uses infrared
• C. Requires line-of-sight
• D. Not used in WPAN

Answer: (A)

Bluetooth relies on radio waves to transmit data, enabling short-range wireless communication within a personal area network (WPAN). This RF approach lets devices connect and exchange information without needing to be in direct line of sight, and it typically operates in the 2.4 GHz ISM band with techniques like frequency hopping to reduce interference. Unlike infrared, which requires a clear, unobstructed path between devices, Bluetooth can work through walls and around objects. As a WPAN technology, it is designed specifically for close-proximity connections between personal devices such as headsets, keyboards, mice, and data transfer between gadgets.
