Since the 802.11r (FT) plus Over the Distribution method requires connectivity to the currently associated access point, this
method may not work well if the phone is not always able to communicate with the current access point as well as the target
access point, which could occur in non-open environments if line of sight to both the current access point and the target access
point can not be retained when a roaming event occurs.
The Cisco IP Phone 8861 and 8865 support 802.11r (FT) with WPA2-PSK or WPA2 and CCKM with WPA2 or WPA.

Note: If deploying the Cisco IP Phone 8861 or 8865 into an environment where other Wi-Fi phone models exist but those Wi-
Fi phone models do not support 802.11r (FT), then should be able to use that same pre-existing SSID for the Cisco IP Phone
8861 or 8865, but is recommended to enable 802.11r (FT) utilizing the Over the Air method on top of the other pre-existing key
management types (e.g. 802.1x, CCKM, or 802.1x + CCKM); assuming the other Wi-Fi phone models can interoperate in an
802.11r (FT) enabled network while not utilizing 802.11r (FT).

Interband Roaming
The Cisco IP Phone 8861 and 8865 default to Auto for the frequency band mode, which enables interband roaming and
currently gives preference to the strongest signal. Typically this will give preference to 2.4 GHz over 5 GHz due to 2.4 GHz
having a stronger signal in general assuming the power levels are the same.
At power on, the Cisco IP Phone 8861 and 8865 will scan all 2.4 and 5 GHz channels when in Auto mode, then attempt to
associate to an access point for the configured network if available.
If configured for 5 GHz only or 2.4 GHz only mode, then just those channels are scanned.
It is recommended to perform a spectrum analysis to ensure that the desired bands can be enabled in order to perform interband
roaming.

Power Management
The power supply (CP-PWR-CUBE-4=) is required to enable the Cisco IP Phone 8861 or 8865 for wireless LAN mode, as there
is no internal battery.
