Step 3. Radio Wave Environmental Investigation
●Purpose
For a stable use of the WD system, check with the “Radio Wave Environmental Investigation System” in the
targeted installation area, deciding upon the best possible WD wireless for each area, and the location for the
receiver installation. When purchasing the Startup Kit, a request for using the “Radio Wave Environmental
Investigation System” is included in the "Customer Registration Guide".
(Also check our catalog, website, etc., for areas where the service is provided free-of-charge.)
Note
About the “Radio Wave Environmental Investigation System”
(1) The investigation into the wireless environment of the WD installation area is by using a 2.4GHz band
spectrum analyzer (explained in the previous section) to propose the optimum wireless channels to be
used for the WD system.
(2) The optimal installation location for the receiver is selected by monitoring the site on the recommended
WD wireless channel; testing the effective radio wave distance from the recommended position for all the
equipment in 4 corners of the target area, with a radio wave intensity measuring jig and tool to verify the
effective location for the receiver. The recommended location, position, height, direction is used when
installing the receiver and while the receiver is in operation.
CAUTION
- The proposal is based on a guaranteed operation under the environmental conditions when tested.
- A wireless channel other than the recommended channel may be better in some cases, due to a change in
environmental noise from other equipment. In that case, it is recommended to establish a test operation
period.
- The on-site investigation work takes approximately 2 hours per area.
- The “Radio Wave Environmental Investigation Report” is submitted at a later date.
