Support for Additional Platform
Client utility and driver release 2.72 supports one new Windows CE .NET platform: ARMv4I.
Support for WPA-PSK
Wi-Fi Protected Access (WPA) supports two mutually exclusive key management types: WPA and
WPA-Pre-shared Key (WPA-PSK). With WPA key management, clients and the authentication server
authenticate to each other by using an EAP authentication method, and the client and the server generate
a pairwise master key (PMK). The server generates the PMK dynmically and passes it to the access
point. However, with WPA-PSK key management, you configure a pre-shared key on both the client and
the access point. The pre-shared key is used as the PMK.

In previous releases, you could only configure WPA-PSK though the Windows CE wireless
configuration utility. In release 2.72, you can configure WPA-PSK from the ACU. You can now select
“WPA-PSK” in the “Network Security Type” field and then enter the WPA-PSK pass phrase in the “User
Password” field.
