312-50V13 · Question #371

From the following table, identify the wrong answer in terms of Range (ft). Standard Range (ft) 802.11a 150­150 802.11b 150­150 802.11g 150­150 802.16 (WiMax) 30 miles

The correct answer is A. 802.16 (WiMax). The 802.16 (WiMax) entry is the wrong answer because its range is stated in miles, not feet, unlike the other 802.11 standards which are typically measured in feet for indoor/short-range use.

Why each option

The 802.16 (WiMax) entry is the wrong answer because its range is stated in miles, not feet, unlike the other 802.11 standards which are typically measured in feet for indoor/short-range use.

A802.16 (WiMax)Correct

The 802.16 (WiMax) standard is designed for metropolitan area networks with ranges up to 30 miles, making its typical range vastly different in magnitude and unit from the 802.11 Wi-Fi standards, which are correctly listed with ranges around 150 feet.

B802.11g

802.11g is a Wi-Fi standard with a typical indoor range around 150 feet, so its entry is consistent with the table's general representation.

C802.11b

802.11b is a Wi-Fi standard with a typical indoor range around 150 feet, so its entry is consistent with the table's general representation.

D802.11a

802.11a is a Wi-Fi standard with a typical indoor range around 150 feet, so its entry is consistent with the table's general representation.
