Calculating Tag Movement Speed

When communicating with a moving Tag, specify auto or repeat as the communications designation.
The maximum movement speed for the Tag at this time can be calculated simply using the following
formula.
Maximum movement speed=
D (movement distance within the communications area) is calculated from the actual measurement or com-
munications area between the Antenna and Tag.
As noise countermeasures, the Reader/Writer will perform resend processing as internal software processing if a com-
munications error occurs between the Tag and Antenna. Therefore, the communications time will depend on the onsite
ambient noise, so be sure to check with actual equipment beforehand. The communications area calculation may not be
executed as resend processing.
