Which wireless standard operates on 5 GHz frequency?

• A. 802.11n
• B. 802.11g
• C. 802.11ac
• D. 802.11b

Answer: (C)

The 802.11ac wireless standard operates on the 5 GHz frequency. This standard was developed to enhance speed, capacity, and performance for wireless networking, particularly in environments with high demand for bandwidth. The use of 5 GHz allows for a wider channel bandwidth and reduced interference compared to lower frequency bands, which is crucial for supporting high-throughput applications like HD video streaming and online gaming. Additionally, while 802.11n can operate on both 2.4 GHz and 5 GHz frequencies, it is not exclusively a 5 GHz standard. 802.11g and 802.11b, on the other hand, both operate solely in the 2.4 GHz frequency range and are older standards that offer lower speeds and capacity compared to 802.11ac. This makes 802.11ac the most relevant choice when identifying a standard that operates specifically at 5 GHz.
