Which of the following is an example of a wireless personal area network (WPAN)?

• A. Wi-Fi
• B. Bluetooth
• C. Zigbee
• D. LTE

Answer: (C)

Bluetooth is an example of a wireless personal area network (WPAN) technology. WPANs are designed for short-range communication between devices, typically within a range of a few meters to tens of meters. Bluetooth operates effectively within this range, providing a means for devices such as smartphones, headphones, and smartwatches to connect and communicate wirelessly. Zigbee is another WPAN technology that is aimed at energy-efficient communication for applications such as home automation and industrial control. While Zigbee is also correct in the context of WPANs, if the focus is specifically on Bluetooth as a prominent example, it highlights how various WPAN technologies serve the purpose of creating networks between personal devices without the need for extensive infrastructure. Wi-Fi is primarily designed for local area networks (LANs) and covers much larger distances than typical WPAN technologies do, making it unsuitable for this classification. LTE (Long Term Evolution) is a standard for high-speed wireless communication for mobile devices and is also not relevant to WPAN as it involves broader, cellular communication networks.
