Description
802.11 Mode
Present only on the RLX2-IHNF radio. There are three possible mode
settings:
802.11a/g
The radio acts as an 802.11a radio on the 5 GHz band, and an 802.11g
radio on the 2.4 GHz band. Data rates will be limited to the 802.11 a/g
rates (54 mbps maximum). 802.11n operational features will be
disabled. It is not necessary to select this mode for RLX2-IHNF radios
to link to other RLX2 or RLXIB series radios; they will link their best
possible speeds regardless of mode. This mode is not commonly used.
It is mainly used to allow 802.11 a/b/g client devices that cannot link to
802.11n devices to work. One example of such a device is the ProSoft
1734-AENTR wireless I/O client.
802.11n
Default operational mode of the RLX2-IHNF radio. All 802.11n features
are operational, and 20 MHz wide channels are used.
802.11.n wide
Utilizes adjacent pairs of 20 MHz-wide channels as a single 40 MHz-
wide channel. This allows the fastest data throughput to other 802.11n
devices. Only 802.11n devices can utilize this mode, but all RLX2
radios will link at their best speed regardless of mode.
Channels in the 5 GHz band are 20 MHz apart, so 802.11n wide mode
occupies only two channels in that band. However, channels in the 2.4
GHz band are spaced only five MHz apart, so 802.11n wide mode in
the 2.4 GHz band occupies eight adjacent channels! Since there are at
most 13 channels in the 2.4 GHz band, and only three channels do not
overlap others, it is not recommended to enable wide mode on 2.4 GHz
band channels.
Channel list (master
radio)
Indicates the channel number as well as the frequency for operation in
the 2.4 GHz or 5 GHz bands. The available channels in the radio will
vary based on the model and country configuration. Please see section
0 for a comprehensive list of all frequencies for all RLX2 radio models.
RLX2-IHNF radios can operate on 5 GHz
frequencies that are subject to Dynamic Frequency Selection
regulations, and have a special channel selection called DFS Auto
Select. See section 6.8.2 for further details
Important: When choosing an antenna for use with the RLX2 radio,
make sure it supports the frequency range set in the configuration for
the radio.
Repeater
Configures a radio as a repeater. The repeater mode is the normal
radio mode for the network, while the master mode is more of a special
setting to establish the network channel and define the root of the
network tree. Repeater radios help extend the range of a network and
help create the signal "bridges" that allow networked radios to
communicate. All RLX2 radios are capable of repeating.
Parent Link settings
Specifies how a repeater radio connects to the network. For
information, see Parent Link settings.
