What is the speed range of 802.11n?

100 to 300Mbps
150 to 600Mbps
50 to 150Mbps
200 to 800Mbps

The correct answer is: 150 to 600Mbps

802.11n is a wireless networking standard that operates on both the 2.4GHz and 5GHz frequency bands, providing increased speed and range compared to previous Wi-Fi standards. The speed range of 802.11n is typically between 150 to 600Mbps, making option B the correct answer. Option A (100 to 300Mbps) is incorrect because it is the speed range for 802.11g, an earlier Wi-Fi standard. Option C (50 to 150Mbps) is incorrect because it is the speed range for 802.11b, an even earlier Wi-Fi standard. Option D (200 to 800Mbps) may seem like a possible answer as it falls within the 802.11n speed capabilities, but it would be incorrect as it is not the typical speed range for this standard. It is important to remember that speed ranges are not set in stone and can vary depending on factors such as interference, distance from the router, and number of connected devices. Therefore, option B provides the most accurate and realistic speed range for 802.11n.
