Which of the following is not a characteristic of the 802.11n wireless standard?
|
Multiple Input/Multiple Output (MIMO)
|
|
Operates at both the 2.4 and 5.0 GHz ranges
|
|
Maximum data signaling rate of up to 600 Mbps

Explanation:
Detailed explanation-1: -802.11a is incompatible with the 802.11b and 802.11g wireless standards.
Detailed explanation-2: -Both 802.11a and 802.11b are wireless transmission standards for local area networks, but 802.11a uses a 5 GHz frequency, while 802.11b operates on a 2.4 GHz band. The 802.11b Wi-Fi standard provides a wireless range of roughly 35 meters indoors and 140 meters outdoors.
Detailed explanation-3: -802.11n used MIMO (Multiple Input Multiple Output) where multiple transmitters/receivers could operate simultaneously at one or both ends of the link to a single device. This provided a significant increase in data without needing a higher bandwidth or transmit power.
