If the AP detects that the signal strength of the STA is weak, the AP uses a high transmit power to send packets.
A. TRUE
B. FALSE
Question 5
To shorten the STA roaming time, the APs perform 4-way handshake using WPA and WPA2 to negotiate keys.
In this way, negotiation packets are not forwarded to the AC, reducing the time required.
