Question 1
What is the maximum theoretical throughput of the 802.11ac (Wi-Fi 5) standard?
Answer: 802.11ac supports a maximum theoretical throughput of up to 3.5 Gbps (with multi-user MIMO and channel bonding), operating exclusively on the 5 GHz band.
Question 2
Which 802.11 standard introduced support for the 6 GHz frequency band in addition to 2.4 GHz and 5 GHz?
Answer: 802.11ax (Wi-Fi 6E) introduced support for the 6 GHz band, offering less congestion and wider channels alongside the existing 2.4 GHz and 5 GHz bands.
Question 3
What frequency band and maximum speed does the 802.11g standard use?
Answer: 802.11g operates on the 2.4 GHz band with a maximum theoretical speed of 54 Mbps, and it is backward compatible with 802.11b devices.
Question 4
Which 802.11 standard first introduced MIMO (Multiple Input Multiple Output) technology to increase throughput?
Answer: 802.11n (Wi-Fi 4) first introduced MIMO technology, allowing simultaneous use of multiple antennas to increase throughput up to 600 Mbps on both 2.4 GHz and 5 GHz bands.
Question 5
What key technology does 802.11ax (Wi-Fi 6) introduce to improve efficiency in high-density environments?
Answer: 802.11ax introduces OFDMA (Orthogonal Frequency Division Multiple Access), which allows a single transmission to serve multiple clients simultaneously, greatly improving efficiency in crowded environments.
