Figure 31: Antenna Switching Internal Block Diagram
If the Antenna Switching Diversity function is enabled, the function is automatically done by PHY
hardware block. The basic operation scheme is as follows:
● Antenna's RSSI decision is made for 11b PPDU, except for 11g/n PPDU
● When PHY hardware detects the existence of 11b PPDU, it stores RSSI
● After it switch to another antenna, the RSSI stored and decision is made which antenna has
better RSSI
● This operation is done during 11b PPDU's preamble duration to protect corruption of 11b PPDU
data reception
● The decided antenna is not changed until there is a new 11b PPDU
