LAPAC1750PRO Access Point Software User Manual
Multidomain This feature is configurable on a per radio basis By
default it is enabled
Regulatory
Mode
Multidomain Regulatory Mode (World Mode) causes
the AP to broadcast which country it is operating in
as a part of its beacons and probe responses This
allows client stations to operate in any country without
reconfiguration
Disabling this feature prevents the country code setting
from being broadcast in the beacons However, this
only applies to radios configured to operate in the g
band (2 4 GHz band) For radios operating in the a band
(5 GHz band), the AP software configures support for
802 11h When 802 11h is supported, the country code
information is broadcast in the beacons
STBC Mode This field is available only if the selected radio mode
includes 802 11n
Space Time Block Coding (STBC) is an 802 11n technique
intended to improve the reliability of data transmissions
The data stream is transmitted on multiple antennas so
the receiving system has a better chance of detecting at
least one of the data streams
Select one of the following options:
• On — The AP transmits the same data stream on
multiple antennas at the same time
• Off — The AP does not transmit the same data on
multiple antennas
Section 3: Configuring the Access Point
Protection The protection feature contains rules to guarantee
that 802 11 transmissions do not cause interference
with legacy stations or applications By default, these
protection mechanisms are enabled (Auto) With
protection enabled, protection mechanisms will be
invoked if legacy devices are within range of the AP
You can disable (Off ) these protection mechanisms
When protection is off, legacy clients or APs within range
can be affected by 802 11n transmissions Protection
is also available when the mode is 802 11b/g When
protection is enabled in this mode, it protects 802 11b
clients and APs from 802 11g transmissions
Note: This setting does not affect the ability of the
client to associate with the AP
Beacon Beacon frames are transmitted by an AP at regular
intervals to announce the existence of the wireless
Interval
network The default behavior is to send a beacon frame
once every 100 milliseconds (or 10 per second)
Enter a value from 20 to 2000 milliseconds
DTIM Period Specify a DTIM period from 1 to 255 beacons
The Delivery Traffic Information Map (DTIM) message is
an element included in some beacon frames It indicates
which client stations, currently sleeping in low-power
mode, have data buffered on the AP awaiting pick-up
The DTIM period you specify indicates how often the
clients served by this AP should check for buffered data
still on the AP awaiting pickup
The measurement is in beacons For example, if you set
this field to 1, clients will check for buffered data on the
AP at every beacon If you set this field to 10, clients will
check on every 10th beacon
