6.0 Summit Radio Utility
Encryption involves scrambling transmitted data so that
Encryption
it can be read only by the intended receiver, which has the
proper key to decrypt unscramble the encrypted data. In
Summit Client Utility, the Encryption setting in a profile
can refer not just to an encryption method but also to an
authentication method and an encryption key manage-
ment protocol.

Table.
Maximum Maximum (Max PSP) is a power save mode where the
access point buffers incoming messages for the radio. The
radio occasionally 'wakes up' to determine if any buffered
messages are waiting and then returns to sleep mode after
it requests each message. This setting conserves the most
power but also provides the lowest throughput. It is recom-
mended for radios in which power consumption is most
important (such as small battery-operated devices).

mode allows the user to set the radio to its optimum power-
consumption setting.
Maximizing battery life for full shift operation is an impor-
tant consideration for vendors and users of hand-held data
terminals and similar devices. Summit provides a number
power save modes that can significantly reduce the radio's
power consumption and maximize the battery life of the
host device.
Summit supports the three following power save modes:
• CAM (Constantly Awake Mode)
• Fast
• Maximum
When in power save mode, the radio "sleeps" most of the
time and "wakes up" only when it has data that needs to
be sent to the infrastructure (or at an interval determined
between the station and the access point). When the radio
is awake, the access point also delivers to the station any
data that has been buffered during the radio's sleep period.
Radio Mode Radio mode is an SCU Profile setting that indicates the
use of 802.11a, 802.11g, 802.11b, and 802.11n frequencies
and data rates when interacting with an access point,
or the use of ad hoc mode to associate to a station radio
instead of an access point.
When SCU operates with a Summit 802.11g radio, an
administrator can select from among the following radio
mode values:
• B rates only - 1, 2, 5.5, and 11 Mbps
• G rates only - 6, 9, 12, 18, 24, 36, 48, and 54 Mbps
• BG rates full - All B and G rates
• BG Subset - 1, 2, 5.5, 6, 11, 24, 36, and 54 Mbps. This
should only be used with Cisco APs running IOS in
autonomous mode (without controllers). For Cisco
APs that are tied to controllers and for non-Cisco APs,
Summit recommends BG rates full.
• Ad Hoc - When selected, the Summit radio uses ad hoc
mode instead of infrastructure mode. In infrastructure
mode, the radio associates to an AP. In ad hoc mode, the
radio associates to another station radio that is in ad hoc
mode and has the same SSID and, if configured, static
WEP key.
Note: The default is BG rates full.

When SCU operates with a Summit 802.11a/g radio, an
Radio Mode
administrator can select from the following radio mode
(cont'd)
values:
• B rates only - 1, 2, 5.5, and 11 Mbps
• G rates only - 6, 9, 12, 18, 24, 36, 48, and 54 Mbps
• BG rates full - All B and G rates
• A rates only - 6, 9, 12, 18, 24, 36, 48, and 54 Mbps (same
as G rates)
• ABG rates full - All A rates and all B and G rates, with
A rates (the 802.11a radio) preferred (see "Preferred
Band for 802.11a/g Radio" for more information).
• BGA rates full - All B and G rates and all A rates, with
B and G rates (the .11g radio) preferred (see "Preferred
Band for 802.11a/g Radio" for more information).
• BG Subset - 1, 2, 5.5, 6, 11, 24, 36, and 54 Mbps. This
should only be used with Cisco APs running IOS in
autonomous mode (without controllers). For Cisco
APs that are tied to controllers and for non-Cisco APs,
Summit recommends BG rates full.
• Ad Hoc - When selected, the Summit radio uses ad hoc
mode instead of infrastructure mode. In infrastructure
mode, the radio associates to an AP. In ad hoc mode,
the radio associates to another station radio that is in
ad hoc mode and has the same SSID and, if configured,
static WEP key.
Note: The default is ABG rates full.
Note: See "802.11a/g Radio Mode with 802.11g Radio"
Preferred Band for 802.11a/g Radio
When the radio mode value is ABG rates full, the 5 GHz
(A) band is preferred over the 2.4 GHz (BG) band. When
the radio mode value is BGA rates full, the 2.4 GHz (BG)
band is preferred over the 5 GHz (A) band.
When trying to associate to an access point, the radio
considers access points in the preferred band. If the radio
is able to associate to one of these access points, then the
radio will not try to associate to an access point in the
other band.
The only time that the radio attempts to associate to an
access point in the non-preferred band is when the radio is
not associated and cannot associate in the preferred band.
When roaming, the radio considers only access points in
the current band (the band in which the radio is currently
associated). The radio will consider an access point in the
other band only if it loses association.
802.11a/g Radio Mode with 802.11g Radio
When an administrator tries to create or edit a profile,
SCU determines which radio is operating in the device
and populates the available radio mode values accord-
ing to the radio type. Suppose a profile created for an
802.11a/g card is loaded on a device with an 802.11g card.
If a radio mode value of A rates only, ABG rates full, or
BGA rates full was set in the profile, then SCU displays a
value of BG rates full. If the administrator does not save
any changes to the profile, then SCU leaves the profile,
including the radio mode, unchanged. If the administra-
tor saves any changes to the profile, then SCU saves the
radio mode value as BG rates full.
