RSSI The received signal strength indicator (RSSI) is a measure of signal strength
in decibels with respect to milliwatts (dBm).
Data Encryption Indicates whether the data exchanged with this access point is encrypted.
Value: Secure or Open
Infrastructure Mode Indicates whether the device is an access point operating in infrastructure
mode or another client adapter operating in ad hoc mode.
Value: Infrastructure or Ad-Hoc
Network Type The IEEE 802.11 standard that describes the access point’s radio band.
Value: A, B, or G
Supported Rates The rate at which the access point is capable of transmitting and receiving
data packets.
Value: 1, 2, 5.5, 6, 9, 11, 12, 18, 24, 36, 48, or 54 Mbps
Channel (Frequency) The channel and radio frequency that the access point is currently using for
communications.
Value: Dependent on radio band and regulatory domain
Beacon Period The amount of time between access point beacons in Kilomicroseconds
(Kµsec).
Note One Kµsec equals 1,024 microseconds.
ATIMWindow Announcement traffic information message (ATIM) window. The brief time
period immediately following the transmission of each beacon in an ad hoc
network. This value is expressed in Kilomicroseconds (Kµsec).
Note One Kµsec equals 1,024 microseconds.
Note This parameter’s value is 0 when the device is operating in
infrastructure mode.
DSConfig The frequency of the selected channel.
Range: 2,412,000 to 2,484,000 kHz (802.11b/g);
5,000,000 to 6,000,000 kHz (802.11a)
HopPattern The hop pattern used to determine the hop sequence.
HopSet A set of patterns used to determine the hop sequence.
DwellTime The maximum amount of time that the access point should remain on a
channel. This value is expressed in Kilomicroseconds (Kµsec).
Note One Kµsec equals 1,024 microseconds.
Name The access point’s name. It is shown only if the access point was configured
with a name, Aironet Extensions are enabled (on access points running Cisco
IOS Release 12.2(4)JA or later), and the access point transmits this
information.
Note This field shows up to 15 characters although the name of the access
point may be longer.
