What is the maximum net bit rate specified by 802.11n?

The maximum net bit rate specified by 802.11n is indeed 600 Mbit/s. This standard was a significant enhancement over previous Wireless LAN standards, allowing for higher throughput due to several technological advancements.

802.11n introduced multiple-input multiple-output (MIMO) technology, which utilizes multiple antennas at both the transmitter and receiver to improve communication performance and increase data capacity. Additionally, it supports channel bonding, where two 20 MHz channels can be combined to create a wider 40 MHz channel, further boosting the data rate.

The 600 Mbit/s maximum is achieved under optimal conditions, utilizing all the MIMO streams and channel bonding capabilities. Understanding this metric is crucial for evaluating Wi-Fi network performance, especially in environments where multiple users and devices are competing for bandwidth.

While the other options suggest rates that may seem plausible, they either exceed the actual maximum specified by the 802.11n standard or do not reflect the capabilities provided by the specifications established.
