1.2.2 Checkpoints concerning the effects on existing wireless LAN systems
When a DR Wireless SYSTEM and an existing wireless LAN system share the same frequency, care is
required since the wireless communication of the DR Wireless SYSTEM will adversely affect the
existing wireless LAN system.
If, for instance, a DR Wireless SYSTEM shares the same channels with a device for which the
communication timing is critical or with a device requiring a data rate above a specific level, the image
transfer of the DR Wireless SYSTEM may interfere with the normal operation of the other device.
Particular care is required when the frequencies used overlap in part because the resulting effects may be
significant.
1.2.3 Concerning the effects from existing wireless LAN systems
When checking out the channels used by the existing wireless LAN system, the effect on the image
transfer time is believed to be minimal at a signal strength of around -70 dBm. However, since this value
of -70 dBm is a rough value obtained from experiments, it is essential that images be transferred and that
it be checked that there are no effects.
Particular care is required when the frequencies used overlap in part because the resulting effects may be
significant.
Reference information:
If the signal strength (dBm) cannot be measured using a software application provided with the wireless
LAN adapter or notebook PC, it is possible to view this strength in a simplified manner using the free
"inSSIDer" tool.
