802.11 Standards for WLAN
Communications, on page 24
Determines the signal mode or
priority for selecting signal modes
available in the WLAN. Options are:
•
802.11 b/g: Use only 2.4 GHz
band
•
802.11a: Use only 5 GHz band
•
Auto, 802.11b/g preferred over
802.11a (dual-band)
•
Auto, 802.11a preferred over
802.11b/g (dual-band)
The preferred band, if
available, is used at
power-on, but the
phone may switch to
the less-preferred 2.4
GHz band, if available,
and the preferred band
is lost. After the phone
has connected to the
less-preferred band, it
does not scan for the
preferred band if the
current band is
acceptable, and may
remain connected to
the less-preferred band.
Note
•
Auto, signal strength (RSSI):
Use strongest signal in
dual-band environment
802.11 Mode
AP Association, on page 34Scan Mode is set in the
Cisco Unified
Communications Manager
Administration, and cannot
be set from the phone. The
phone displays the current
setting.
Note
Auto: Always scans when on a call.
If idle and signal strength is
sufficient, the phone does not scan.
Continuous: Always scans.
Single AP: Only scans at power-on
or if the AP connection to the
network is lost.
