What is the speed range of 802.11n?

11Mb/sec
54Mb/sec
150 to 600Mbps
866MBps to 1.3Gb/sec

The correct answer is: 150 to 600Mbps

802.11n is a type of Wi-Fi standard that supports high-speed wireless data transmission. It operates in the 2.4GHz and 5GHz frequency bands and offers a maximum theoretical speed of 600Mbps. However, the actual speed range of 802.11n can vary depending on several factors such as signal strength, interference, and network setup. Therefore, the correct answer is C, which represents the range of 150Mbps to 600Mbps. B, D, and A are incorrect as they do not fully encompass the possible speed range of 802.11n. Option B (54Mbps) is the maximum speed of 802.11g, an older version of Wi-Fi. Option D (866Mbps to 1.3Gbps) is the speed range of 802.11ac, a newer and faster Wi-Fi standard. Option A (11Mbps) is the maximum speed of the oldest Wi-Fi standard, 802.11b. Hence, C is the most appropriate and accurate answer.
