| Q3-1 |
Is there any influence to the human body ? |
| A3-1 |
There is no problem if we do not watch the infrared beam for a long time
and at a short distance. Infrared beam conforms to the standard IEC60825,
and it is gentle to the human body and has no influence. |
| 3-1 |
Wave length of infrared is 850`900nm that is generally used. Infrared beam is concentrated by lens for the 10Mb/s signal transmission, but there is no problem against the human body because the transmission power is much weak compared with the sunshine. |
| Q3-2 |
Is there any influence to other equipment in the same room ? |
| A3-2 |
There is no influence to other precise equipment because it is a kind of the light. |
| 3-2 |
There is no problem in ordinal office and there is no influence to other
equipment by radio wave also. |
| Q3-3 |
Is there any influence from the remote controller of television ? |
| A3-3 |
There is no influence from the infrared of the generally used remote controller. |
| 3-3 |
There is no influence basically from the infrared equipment for example
television remote controller. |
| Q3-4 |
Is it usable from the view point of data security ? |
| A3-4 |
Infrared is different from radio wave and can not pass through the wall.
It has very high security because it has no influence from obstructive
radio wave and there is no leakage of data. |
| 3-4 |
Infrared communication is the transmission type of the line of sight and the signal transmission over wall, floor and ceiling is impossible. So the external leakage of data is much small compared with radio wave LAN. And there is no influence from obstructive radio wave. |
