audio gaps. The required use of the fast AP handoff methods available in R3.0 help reduce the risk of
„hard handoff‟ situations where full 802.1X key exchanges must occur again. For more information on the
fast AP handoff options see Section 5.3.2. It is always recommended that the authentication server be
located within the same geographic location as the network to which it will be providing authentication

NTP Server

NTP (Network Time Protocol) servers are used to provide uniform time information to network devices.
Many customer sites already use NTP servers for other servers and network infrastructure. This same
NTP server can be used for the wireless telephones as well. The handset uses information obtained from
the NTP server to display the current date and time.
When using WPA2 Enterprise, the handset will also use the NTP server information to determine
start/end date validity for loaded PEAP certificates. If an NTP server is not present in the network the
wireless telephone will be unable to determine when a PEAP certificate has expired. If an NTP Server is
present and the handset determines the PEAP certification in invalid, the handset will not operate and
display an error message.
