Which wireless standard operates on a slower speed but offers greater range?

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

Answer: (D)

The answer is based on the characteristics of the wireless standards outlined in the question. The 802.11b standard operates at a maximum data rate of 11 Mbps and utilizes the 2.4 GHz frequency band. While this speed is relatively slow compared to more recent standards, it allows for better range and penetration through obstacles like walls compared to those that operate on higher frequencies. In contrast, standards like 802.11g, 802.11n, and 802.11ac, while offering significantly higher speeds, tend to operate in both the 2.4 GHz and 5 GHz bands (with 802.11n supporting both) or primarily the 5 GHz band (as with 802.11ac), where the higher frequencies do not travel as far or penetrate as effectively through physical barriers. The trade-off with 802.11b is that, although it is limited in speed, its ability to cover greater distances makes it suitable for certain environments where range is more critical than speed, such as larger homes or public spaces where higher-speed connections aren't necessary across all devices. Thus, the characteristics of 802.11b align perfectly with the question's criteria of a slower speed but greater range.
