Field Description
current operating conditions. The system attempts to use a 400 microsecond
Guard Interval, but will fall back to an 800 microsecond Guard Interval if
excessive data corruption is detected. The radio will periodically attempt to
resume using a 400 microsecond Guard Interval as conditions improve. A 400
microsecond Guard Interval results in about 11% more throughput than
using a 800 microsecond guard interval. The user has no control of the Guard
Interval.
As seen in the table above, absolutely best throughput requires 802.11n
wide mode, more than one antenna, and a RF environment capable of
supporting a 400 microsecond Guard Interval.
Max Basic Rate In addition to the Data Rate setting which controls generic data traffic, the
Basic Rate setting adjusts the rate at which control packets such as Beacons
and ACKs are sent at as well as packets that need to go to the whole network
such as Broadcasts. Because these packets are intended for the whole
network, the Max Basic Rate setting of the Master is advertised to each of
the radios in the network through Beacons. Each radio, other than the
Master, then inherits the Max Basic Rate setting of the Master. Therefore
the setting only needs to be made in the Master radio. The setting in each of
the other radios is disregarded.
Interop Optimization This control allows for ease of configuration for the following controls, for
two specific interoperability scenarios.
RLX2 Bridging optimizes Immediate Broadcasts, Block General Probes and
Range for operation when peer devices are primarily other RLX2s. 3

-Party
Clients optimizes these controls for peer devices such as laptops, tablets,
phones or any other WiFi devices that perform regular power saving are
expecting to connect to this RLX2. If this setting is not used, these client
devices may have difficulty in finding the network SSID, and their
communication may be erratic due to broadcasts not being transmitted
when expected. RLX2 Bridging will still function, although the RLX2 will be
responding to all scanning client devices which may introduce some jitter to
data being transferred.
Immediate Broadcasting Forward multicast traffic immediately, rather than waiting for specific time
intervals.
Block General Probe
Requests Do not respond to general probe requests that are not specific to the radio's
SSID.
Range Allows the radios to account for round trip delays. The Range settings should
be the same in all radios in the network and should be at least large enough
to account for the length of any links. However, increasing the Range beyond
what is necessary can cause a slight decrease in throughput. The default
Long range is 25km, which is valid for all operating modes of all radios.
Reducing the range setting for systems at closer range may improve
throughput.
TX Power Attenuation Sets the output power of the radio.
