Define a RIFS mode to determine whether interframe spacing is applied to access point
transmissions or received packets, both, or neither The default mode is Transmit and
Receive. Interframe spacing is an interval between two consecutive Ethernet frames to
enable a brief recovery between packets and allow target devices to prepare for the
reception of the next packet. Consider setting this value to None for high priority traffic to
reduce packet delay.
Select a space–time block coding (STBC) option to transmit multiple data stream copies
across access point antennas to improve signal reliability. An access point's transmitted
signal traverses a problematic environment, with scattering, reflection and refraction all
prevalent. The signal can be further corrupted by noise at the receiver. Consequently,
some of the received data copies are less corrupt and better than others. This redundancy
means there is a greater chance of using one, or more, of the received copies to
successfully decode the signal. STBC effectively combines all the signal copies to extract
as much information from each as possible. STBC Mode is available on AP81XX (AP8122,
AP8132 and AP8163) model access points only, and is disabled by default.
Enable beamforming to steer signals to peers in a specific direction to enhance signal
strength and improve throughput amongst meshed devices (not clients). Each access point
radio support up to 16 beamforming capable mesh peers. When enabled, a beamformer
steers its wireless signals to its peers. A beamformee device assists the beamformer with
channel estimation by providing a feedback matrix. The feedback matrix is a set of values
sent by the beamformee to assist the beamformer in computing a steering matrix. A
steering matrix is an additional set of values used to steer wireless signals at the
beamformer so constructive signals arrive at the beamformee for better SNR and
throughput. Any beamforming capable mesh peer connecting to a radio whose capacity is
exhausted cannot enable beamforming itself. Transmit beamforming is available on
AP8163 model access point only, and is disabled by default.
Aeroscout Properties
for the selected access point radio:
Use the Forward option to forward Aeroscout packets to the server.
Use the text area to provide a MAC address that identifies that the packet is received
from Aeroscout tags.
Ekahau Properties
for the selected access point radio:
Use the Forward Host text area to provide the IP address of the Ekahau Engine.
Use the Forward Port spinner to configure the port on which to forward captured packets
to the Ekahau Engine.
Use the text area to provide a MAC address that identifies that the packet is received
from Ekahau tags.
Non-Unicast Traffic
values for the profile's supported access point radio and its connected wireless
Use the Select drop-down menu to launch a sub screen to define the data rate broadcast
and multicast frames are transmitted. Seven different rates are available if the not using
the same rate for each BSSID, each with a separate menu.
