VerifiedInformation Security and Networking Fundamentals

WPAN technologies let users establish ad hoc wireless communications among devices such as PDAs, cellular phones, or laptops used within a personal space of up to 10 meters. Plugging in and the capability to lock devices against unauthorized access are two key advantages of WPAN. What are the two most widely used primary WPAN technologies?

Explanation

Bluetooth supports ad hoc personal-area networking among nearby devices, including a group ad hoc network role. In the traditional WPAN classification for personal devices, the other widely used technology is IrDA. ZigBee is associated with low-rate, low-power sensor and control networks, and NFC is intended for near-contact communications rather than the stated roughly 10-meter personal-device range.
