From the following table, identify the wrong answer in terms of Range (ft).
From the following table, identify the wrong answer in terms of Range (ft).
The 802.16 (WiMax) standard, typically used for longer-range communication, is described as having a range of 30 miles in the table. However, this value is not given in feet like the other standards, creating an inconsistency. While WiMax can cover distances up to approximately 31 miles, which is correct in terms of the technology's capability, the table mixes units and should ideally have a consistent range measurement.

Wimax also does not have a range of 30 miles. Answer should be wimax.
802.16 does have a range of ~31 miles/40 km
