Which of the following standards would be used on a wireless router to support speeds up to 150 Mbps?

In basic terms, 802.11n is faster than 802.11g, which itself is faster than the earlier 802.11b. On the company website, Apple explains that 802.11n offers “greater performance, more range, and improved reliability”. Apple also notes:

Among its key innovations, 802.11n adds technology called multiple-input multiple-output (MIMO), a signal processing and smart antenna technique for transmitting multiple data streams through multiple antennas. The result? Up to five times the performance and up to twice the range compared to the earlier 802.11g standard.

802.11n can operate on either the 5 GHz frequency at a theoretical maximum speed of 300 Mbps or on the 2.4 GHz frequency in “mixed mode” which will support systems only capable of using 802.11b or 802.11g, but it will slow the entire network down to the maximum speed of the earliest standard connected
