Which of the following technologies has the SHORTEST wireless range for printing?

The correct answer is D. Infrared. Infrared (IrDA) has an extremely short effective range of roughly 1 meter (about 3 feet) and requires a clear, unobstructed line-of-sight between the two devices. Bluetooth typically reaches 10 meters (Class 2) or more. 802.11a has an indoor range of roughly 35 meters, and…

Explanation

Infrared (IrDA) has an extremely short effective range of roughly 1 meter (about 3 feet) and requires a clear, unobstructed line-of-sight between the two devices. Bluetooth typically reaches 10 meters (Class 2) or more. 802.11a has an indoor range of roughly 35 meters, and 802.11g reaches approximately 38 meters indoors. Infrared's combination of near-contact range and line-of-sight requirement makes it by far the most limited of these wireless technologies.
