Channel setting guidelines
1.1 Guidelines
Wireless LAN channel setting guidelines for adding the DR Wireless system to an existing wireless LAN
environment are described below. These guidelines apply to both the 2.4 GHz and 5 GHz bands.
1.1.1 Basic
guidelines
Check out the channels used in the existing wireless LAN system, and set the channels without
interference.
If interference cannot be avoided, select the same channels as the ones used by the existing wireless
LAN system.
Fig. 1 shows the above flow to be followed for establishing the settings.
1.1.2
Guidelines for multiple DR Wireless SYSTEM (CXDI-70C or CXDI-80C)
Since, in the case of a system consisting of a multiple number of DR Wireless SYSTEM (CXDI-70C or
CXDI-80C), the probability that more than one image transfer will take place at the same time is
considered to be low, set all the DR Wireless SYSTEM to the same channels by following the flow
shown in Fig. 1 when operation will not call for images to be transferred at the same time or when
delays in image transfer are permissible.
However, in cases where multiple DR Wireless SYSTEM are to be installed in proximity and images
tend to be transferred at the same time, consider each DR Wireless SYSTEM as an existing wireless
LAN system and, following the sequence shown in Fig. 1, set different channels for each of the DR
Wireless SYSTEM as far as this is possible.

*1
: In the 2.4 GHz band it is not possible to specify two non-interfering channels in HT40.
*2
: In the 5 GHz band the channel pairs are predetermined and there is no way to set the same primary
channel only. In contrast, in the 2.4 GHz band it is possible to specify either of two channels for each
primary channel, such as 6CH below 2CH or 6CH above 10CH.
1.2
Checkpoints when setting the channels
1.2.1
Checkpoints when checking out existing wireless LAN systems
When checking out the conditions under which existing wireless LAN systems are being used to install
the systems, it is possible that systems are available under which the channels are automatically set
rather than having fixed channels for the existing system. For this reason, the administrator of the facility
concerned who is conversant with the conditions under which the wireless LAN systems are used
should be consulted. Care is required since if only the signal conditions during installation have been
measured, the automatic setting of the channels may cause channels which are different from the ones
identified during installation to be used.
If possible, in setting the DR Wireless SYSTEM channels, it is desirable to ask that fixed channels be
used for the existing wireless LAN systems and that the channels be set in such a way that no parts of
the frequencies used will overlap.
