4 Radios
Maximum In Max Power Savings (Max PSP) mode, the
access point buffers incoming messages for
the radio, which wakes up periodically and
connects to the access point to see if any
buffered messages are waiting. The radio
requests buffered messages and then goes
back to sleep. It conserves the most power
but offers the lowest throughput. It is
recommended when battery power is in
use.
Fast Power Save Mode (Fast PSP) switches
between the two modes described above,
depending on network traffic. This mode
switches to CAM when retrieving a large
number of packets and switches back to
PSP (= Power Save Polling) after the
packets have been retrieved. It is
recommended when power consumption is
a concern but you need greater throughput
than that allowed by Max PSP.
Default: Fast
Bit Rate The measurement of how much data is transmitted in a given
amount of time from one location to another.
Value: Auto (rate is negotiated automatically with the AP)
Default: Auto
Radio Mode Use of 802.11a/b/g/n frequencies and data rates when
interacting with an AP, or the use of ad hoc to associate to a
station radio.
Value: B rates only, BG rates full, G rates only, BG LRS, A
rates only, ABG rates full, BGA rates full, Ad Hoc
B rates
only
1, 2, 5.5, and 11 Mbps.
BG rates
full
All B and G rates, plus N rates if supported.
G rates
only
6, 9, 12, 18, 24, 36, 48, and 54 Mbps.
BG LRS 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).
A rates
only
6, 9, 12, 18, 24, 36, 48, and 54 Mbps, plus
N rates if supported.
ABG rates
full
All A rates and all B and G rates, with A
rates (the 802.11a radio) preferred, plus N
if supported.
BGA rates
full
All B and G rates and all A rates, with B and
G rates (the .11g radio) preferred, plus N
rates if supported.
