The 5 GHz band is a frequency band used for wireless networks that offers higher data rates and less interference compared to the more traditional 2.4 GHz band. This band can be found in most modern wireless routers and devices supporting 802.11n, 802.11ac and newer standards such as 802.11ax (WiFi 6). The unit you will encounter is Mbps and stands for "megabits per second" and is a measure of data transfer speed. To convert from Mbps to MB/s (megabytes per second), you need to divide the value in Mbps by eight.
