It is important to allow many industrial protocols to communicate properly over
the RLXIB-IHA radios. The standard 802.11 AP operation for transmitting
broadcast messages is to accumulate them and transmit them only on specific
time intervals. This allows clients that are in power-save mode to wake up at the
synchronized time interval and receive the broadcast packets. However, the
power-save mode is rarely used in industrial networks. Additionally, many
industrial protocols utilize multicast traffic, which is sent as broadcast messages
over the wireless network. By enabling immediate broadcasting, these multicast
messages are not delayed by the wait for the next time interval to occur before
they can be transmitted. This results in improved network performance.
The settings on this form also allow you to configure the transmission rate and
broadcast mode to optimize this radio's use on an industrial network.
Field Description
Max Data Rate The maximum data transmission rate, in megabits per second, for this
radio. Available settings range from 1 to 54.
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.
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 The Range setting 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.
