BreezeACCESS SU-A-EZ 50 Product Manual
If the RTS threshold is set to 20, the SU-A-EZ always sends RTS signals. If set to
2347, the SU-A-EZ never sends RTS signals. If set to any other value, and the
packet size equals or exceeds the RTS threshold, the RTS/CTS (Request to Send /
Clear to Send) mechanism will be enabled.
The SU-A-EZLs contending for the medium may not be aware of each other. The
RTS/CTS mechanism can solve this “Hidden Node Problem.” (Range: 20-2347
bytes: Default: 60 bytes)
Transmit Power Level – Adjusts the power of the radio signals transmitted from
the SU-A-EZ. The higher the transmission power, the farther the transmission
range. Power selection is not just a trade off between coverage area and maximum
supported clients. You also have to ensure that high-power signals do not
interfere with the operation of other radio devices in the service area. (Options:
Full, Half, Quarter, Eighth, Min (0 dBm); Default: Full
Modulation Type and Link Rate – Sets the modulation type to limited or fixed.
(Default: limited). It also sets the maximum data rate at which the SU-A-EZ
transmits unicast packets on the wireless interface. The maximum transmission
distance is affected by the data rate. The lower the data rate, the longer the
transmission distance. (Default: 54 Mbps)
MIR uplink – Sets the Maximum Information Rate of the uplink from the SU to
the AU. The MIR value cannot be lower than the corresponding CIR value.
The actual value will be the entered value rounded to the nearest multiple of 128
(N*128).
MIR downlink – Sets the Maximum Information Rate of the downlink from the AU
to the SU. The MIR value cannot be lower than the corresponding CIR value.
The actual value will be the entered value rounded to the nearest multiple of 128
(N*128).
CIR uplink – Sets the Committed Information Rate of the uplink from the SU to
the AU. The CIR value cannot be higher than the corresponding MIR value.
The actual value will be the entered value rounded to the nearest multiple of 128
(N*128).
CIR downlink – Sets the Committed Information Rate of the downlink from the
AU to the SU. The CIR value cannot be higher than the corresponding MIR value.
NOTE
All wireless devices must be configured with the same Key values to communicate with an AU.
