Unicast messages are addressed to a single device on the network. Broadcast messages are
addressed to multiple devices. When using WPA2-CCMP, a wireless client can use 2 keys: one
unicast key, for its own traffic to and from an access point, and one broadcast key, the common key
for clients in that subnet.
Pre-Shared Key Enter either an alphanumeric string of 8 to 63 ASCII characters or 64 HEX characters as the
primary string both transmitting and receiving authenticators must share. The alphanumeric string
allows character spaces. The access point converts the string to a numeric value. This passphrase
saves the administrator from entering the 256-bit key each time keys are generated.
