Explanation:
Detailed explanation-1: -Bluetooth: Bluetooth technology is the implementation of a protocol defined by the IEEE 802 IS standard, i.e. the IEEE standard protocol that defines a wireless personal area network (PAN) operable in a room is Bluetooth, that has a range of 10 meters only.
Detailed explanation-2: -Today, most PANs for everyday use are wireless. WPANs use close-range wireless connectivity protocols such as Bluetooth. The range of a WPAN is usually very small, as short-range wireless protocols like Bluetooth are not efficient over distances larger than 5-10 meters.
