Many personal computers and LAN environment are needed for the training including company and others. But it is difficult to prepare always the wide space like personal computer room except school. For the effective and multi-purpose use of the limited space, not only the arrangement of desk and chair but the environment for personal computer connection to network are needed.

Infrared Communication LAN makes it easy to construct the layout free LAN environment.

In the information service section of S company the multi-purpose floor is used for personal computer training. They planned the cable LAN with cable wiring under floor at first. But the removal of desk, the rewiring of cable and the setup of personal computer every time of training need the extremely hard work and it is not effective to prepare the personal computer room only for the training.

The plan of Infrared Communication LAN was decided because the fixed equipment is not necessary.

The necessary personal computers can be setup at will according to the training program and the trainee can move in the training room without fall down by cable.

We will recommend the deployment of Infrared Communication LAN for not only the training but the normal office work from the viewpoint of rationalization and work efficiency.
