From the following table, identify the wrong answer in terms of Range (ft).

802.11b operates at 2.4 GHz with a well-established indoor range of approximately 300 ft, which is a correct and commonly accepted value for this standard.

802.11g also operates at 2.4 GHz and shares a typical indoor range of approximately 300 ft with 802.11b, making its table entry correct.

802.16 (WiMax) is a metropolitan-area network standard with a range measured in miles rather than feet, so its distinctly large range figure in the table is correctly categorized.

802.11a uses the 5 GHz frequency band, which attenuates more rapidly through walls and obstacles than the 2.4 GHz band, resulting in a typical indoor range of approximately 150 ft. This is shorter than 802.11b and 802.11g (both approximately 300 ft at 2.4 GHz), so a table listing 802.11a with a range equal to or greater than those standards contains a factually incorrect range value for 802.11a.
