Which wireless standard allows newer devices to achieve the maximum possible transfer rate?

The selection of the 802.11ac wireless standard as the correct answer is based on its enhanced capabilities for achieving the highest data transfer rates among the listed options. The 802.11ac standard, developed after its predecessors, supports wider channels, advanced modulation techniques, and multiple input multiple output (MIMO) technologies, which collectively allow for significantly faster data rates compared to earlier standards.

802.11ac can operate on the 5 GHz band and supports channel widths up to 160 MHz, leading to improved throughput. This standard can provide theoretical maximum speeds of up to several gigabits per second, especially when multiple data streams are used. In contrast, other standards mentioned, such as 802.11a, 802.11n, and 802.11b, offer lower maximum speeds and are generally limited by their older technologies and the narrower channels they utilize.

For instance, 802.11n allows for greater bandwidth and speeds than previous standards but does not reach the higher potentials of 802.11ac. Similarly, 802.11a and 802.11b are considerably slower, with maximum throughput significantly less than that of 802.11n and 802.11ac. Thus, when considering newer
