In addition, the replacement of the antenna on the direction or with the increased capacity can not signal. Of course, it is seldom required, but still a place to be. Large coverage range and provide high speed devices with built by the two antennas in the MIMO mode 5dBi.

WiFi standards

This is another point that deserves attention.
