Which IEEE wireless standards specify transmission speeds up to 54 Mbps?

1. 802.11n and 802.11ac

2. 802.11b and 802.11x

3. 802.11g and 802.11a

4. 802.11x and 802.11r

The correct answer is: 802.11g and 802.11a

The correct answer is based on the capabilities of the specified IEEE wireless standards. The IEEE 802.11g standard operates in the 2.4 GHz band and can achieve maximum transmission speeds of up to 54 Mbps. Similarly, the IEEE 802.11a standard operates in the 5 GHz band, also supporting maximum speeds of 54 Mbps. Both of these standards were released in the early 2000s and marked significant improvements in wireless data rates over earlier standards. This combination of standards provides versatility for various network environments, allowing for faster wireless connections compared to older standards like 802.11b, which topped out at 11 Mbps. Options that include other standards such as 802.11n and 802.11ac refer to enhancements that provide even higher transmission speeds, but they do not meet the specific criteria stated in the question regarding the 54 Mbps limit. Similarly, 802.11x and 802.11r are not standards directly associated with specific transmission rates; 802.11x is used as a placeholder for any of the 802.11 standards, while 802.11r pertains specifically to fast roaming capabilities rather than data transmission speeds. Thus, the choice highlighting 802.11
