Select Show Cell Distance Parameters to view the Cell Distance parameters. In addition, the Measured Maximum Cell Distance and the MAC address of the unit that the mechanism found to be the farthest from the AU are displayed.
4.2.6.2.11 Arbitration Inter-Frame Spacing (AIFS)
The time interval between two consecutive transmissions of frames is called Inter- Frame Spacing (IFS). This is the time during which the unit determines whether the medium is idle using the carrier sense mechanism. The IFS depends on the type of the next frame to be transmitted, as follows:
SIFS (Short
DIFS (Distributed coordination function
DIFS equal SIFS plus AIFS, where AIFS can be configured to a value from 1 to 50 time slots. A unit with a lower AIFS has an advantage over units with a higher AIFS, since it has a better chance to gain access to limited wireless link resources. Typically, AIFS should be configured to two time slots. A value of 1 should only be used in one of the two units in a
NOTE
The AIFS parameter is not applicable when the Wireless Link Prioritization Option is enabled.
The available range is from 1 to 50 (time slots).
The default is 2 time slots.
CAUTION
An AIFS value of 1 should only be used in
