Which technologies are examples of WPAN?

• A. Wi-Fi and Ethernet
• B. Bluetooth and Zigbee
• C. VPN and LAN
• D. Li-Fi and NFC

Answer: (B)

Bluetooth and Zigbee are technologies classified as Wireless Personal Area Networks (WPAN). WPANs are designed for short-range communication between devices, typically within a range of about 10 to 100 meters, making them ideal for personal devices like smartphones, wearables, and home automation gadgets. Bluetooth is widely used for connecting peripherals such as headphones, keyboards, and smartwatches to other devices without the need for cables. Zigbee, on the other hand, is often used in home automation applications, such as smart lighting and security systems, where low power consumption and the ability to connect many devices simultaneously are essential. The other technologies listed do not fall under the WPAN category. Wi-Fi and Ethernet are designed for broader networks and do not limit communication to personal devices only. VPN (Virtual Private Network) and LAN (Local Area Network) refer to networking concepts rather than specific technologies for personal device connectivity. Li-Fi, which uses light for data transmission, and NFC (Near Field Communication), while both wireless technologies, serve different purposes and are not categorized as WPAN.
