RadioProperty Description

Spacing utilizing two 20 MHz channels as a bonded pair, requires that high-throughput be enabled
(checked).40 MHz mode is most often utilized on the 5 GHz frequency band due toa greater
number of available channels.
Thisoption isonl y available when 802.11n (HT) supporti s enabled (checked).
802.11b/gDesired Rate Thedesired 802.11b/g rate defines the estimatedtransmit rate within the WLAN coverage
area. The higher the speed, thesmal ler the coveragearea, and them ore APsrequi red. The
valid valuesare: 54, 48, 36, 24, 18,12, 9, 6, 11, 5.5, 2, 1.
Thisoption isonl y available when 802.11n (HT) supporti s disabled (unchecked or grayed out).
Whenan 802.11n radio type, such as 802.11g+ n or 802.11a/b/g + n, is selected and 802.11n(HT)
supportis enabled (checked) on the 2.4 GHz band, the systemwi ll automatically define the
802.11b/grate. The system looksat the defined 802.11n rate and the distancecovered by the
definedrate; the system then selects a corresponding 802.11b/grate based on the distance
covered.
2.4GHz 802.11 (HT) Support High-throughputis available w hen utilizing the IEEE 802.11nstandard and can be enabled on
the2.4 GHz frequency band when either the
802.11g+ n or 802.11a/b/g+ n mi xed-mode radio typei sselected.
The802.11n (high-throughput) draftstandard supports MIMO (Multiple Input, Multiple Output)
andthe option of 40 MHz mode of operation. However, high-throughput can be utilized on a 20
MHzchannel or on a 40MHz channel (bonded channel pai r).
2.4GHz 802.11n Desired
Rate
Thedesired 802.11n rate defines the estimated transmitrate wi thin theW LANcoverage area.
Thehi gher thespeed, the small er thecoverage area, and the more APs required.
Thisoption isonl y available when 802.11n (HT) supporti s enabled (checked).
Thevali dvalues when using 20 MHz channel spacing: 6.5, 13.0,19.5, 26.0, 39.0, 52.0, 58.5,65.0,
78.0,104.0, 117.0, 130.0.
Thevali dvalues when using 40 MHz channel spacing: 13.5, 27.0,40.5, 54.0, 81.0, 108.0,121.15,
135.0,162.0, 216.0, 243.0,270.0.
2.4GHz Use 40 MHz
Channel Spacing
40MHz operation, which supportshi gher data rates by utilizing two 20 MHz channels as a
bondedpai r, requires thathi gh-throughputbe enabled (checked). Due to a limited number of
channelson the 2.4 GHz frequency band, 40 MHz mode is most often utilized on the 5 GHz
frequencyband where a greater number of channels are available.
Thisoption isonl y available when 802.11n (HT) supporti s enabled (checked).
