Which wireless standard provides a 54 Mbps maximum transfer rate?

The wireless standard that provides a maximum transfer rate of 54 Mbps is 802.11g. This standard operates in the 2.4 GHz frequency band and was introduced to improve upon the earlier 802.11b standard, which offered maximum speeds of 11 Mbps.

802.11g maintains backward compatibility with 802.11b while also providing enhanced data rates. The 54 Mbps is achieved through the use of advanced techniques such as OFDM (Orthogonal Frequency Division Multiplexing), which allows for better data transmission efficiency compared to previous standards. As the 802.11g standard is widely used in many consumer and business Wi-Fi networks, understanding its capabilities is essential for recognizing the evolution of wireless technology.

In contrast, other standards mentioned, like 802.11n and 802.11ac, provide significantly higher maximum transfer rates, while 802.11b is limited to much lower speeds. Hence, identifying 802.11g as the standard with a maximum transfer rate of 54 Mbps highlights its importance in Wi-Fi history.
