3.1.1 Don’t put this equipment adjacent to the devices generating strong
interference emission.
Devices which might generate an interference emission are:
1)
Micro wave oven or industrial medical equipment within the 2,4GHz band
such as an electric scalpel.
2)
Wireless LAN used in 2,4GHz band other than this equipment.
3)
Amateur radio communications equipment used in 2,4GHz band.
Since this equipment has an error detection function, wrong data are not got in or
the file is not destroyed even if a bit error occurs between the wireless
communications due to radio wave interference.
Where a very strong interference is generated continuously, such as a microwave
oven, the wireless communication will not be operated at all.
In such a case, this equipment requires that the sources of generation is to be
removed or kept from this equipment at least 3m.
Also, where a wireless LAN other than this equipment is used, the communication
passing through a gap between both packet communications is possible but the
performance of the throughput will be reduced.
3.1.2
This equipment shall be installed so as not to affect on the radio
transmitting characteristics.
Following installation is recommended.
1)
Keep an antenna apart from metal surfaces.
2)
Set up this equipment away from a concrete walls or pillars.
3)
Set up this equipment away from a metal partition.
It is much preferable to setup this equipment in a condition where an antenna of
the communicating partner is fully visible. Glasses, wooden furniture,
documents, etc do not become a big obstacles for the communications. However a
human body becomes a object shielding and reflecting the radio wave. It is
desirable that the antenna position shall be so arranged that the human body
would not go across a passage of the radio waves.
When the radio waves does not reach within the expected range of the service
area, remove the obstacles which is shielding a radio waves or a source of the
interference, or move the wireless LAN away from the source of the interference.
