WL-5470 POE User’s Manual 48
WPA-PSK (TKIP) / WPA-PSK (AES)
Wi-Fi Protected Access (WPA) with Pre-Shared Key (PSK) provides better security than WEP keys. It does
not require a RADIUS server in order to provide association authentication, but you do have to enter a shared
key for the authentication purpose. The encryption key is generated automatically and dynamically.
There are two encryption types TKIP and CCMP (AES). While CCMP provides better security than TKIP,
some wireless client stations may not be equipped with the hardware to support it.
Pre-shared Key: This is an ASCII string with 8 to 63 characters. Please make sure that both the
WL-5470POE and the wireless client stations use the same key.
Group Key Life Time: A group key is used for multicast/broadcast data, and the re-key interval is time period
that the system will change the group key periodically. The shorter the interval is, the better the security is.
The default is 300 sec.
