Dual band but diff standard, N vs AC

“WiFi is always promoted using 'theoretical' speeds and by this standard 802.11ac is capable of 1300 megabits per second (Mbps) which is the equivalent of 162.5 megabytes per second (MBps). This is 3x faster than the typical 450Mbps speed attributed to 802.11n”
all these network jargons are very very confusing and I believe a lot of these companies use these to market their products.
Anyways, 802.11N also supports 2.4GHz and 5GHz, but 802.11ac is the latest technology that supports higher speeds (due to multiple factors that is too lengthy to explain here).
But as a guideline, newer routers should have their standard and "Total speed" part of their name now, for example AC1200, AC1900, AC2300.
AC denotes the standard, and the number behind is the total theoretical achievable speed on both 2.4GHz and 5GHz combined. Higher the number, better the performance.
