 Influence of Inclination
Install the Reader/Writer and RF Tags so that the Reader/Writer and RF Tags are as parallel to each
other as possible.
Communications will be possible even if the Reader/Writer and RF Tags are not parallel to each other;
however, the communications range is affected by the inclination between them as shown in the
following graphs.
