3.3 Tag installation environment specification
Tags with different attributes have different installation environments.For
example, when the reader parameters are the same, the anti-metal tag is mounted
on the metal surface much farther than the distance mounted on a non-metallic
surface.The tags are divided into two categories: anti-metal tags and non-metal tags.
Non-anti-metal tags are recommended to be installed in non-metallic environments. If
there is no legal environment to avoid metal, please refer to the following
implementation rules:
Mounting on metal surface ——Non-anti-metal tags require a buffer to be reserved,
and anti-metal tags can be directly mounted to metal surfaces;
Buffer——Refers to the distance from the tag to the metal surface
1、Non-anti-metal tags are mounted on metal surfaces, buffer ≥20mm, and tag
performance can be retained above 80%；
2、When the anti-metal tags is directly mounted on the metal surface, it can still retain
more than 90% of the original performance;
Embedded metal mounting——anti-metal tags can be directly embedded in metal
applications,non-anti-metal tags are not recommended for embedded metal applications.
Free zone——Refers to the blank area around the tag when the tag is embedded in the
metal.
1、When the anti-metal tags are embedded in the metal installation without leaving a
free area, the tag performance can still be maintained above 90%;
2、If the non-anti-metal tags are embedded in the metal mounting surface, the free area
a≥2X, b≥2Y, c≥20mm must be reserved. At this time, the tag can retain more than 80%
of the original performance;

3.4 Electromagnetic wave response in the UHF band
When electromagnetic waves propagate in the UHF band, they are constrained
by some environments (such as metals, walls, liquids, other signal transmitters,
etc.), resulting in reflection and mutual interference.This phenomenon may be
manifested by the fact that the electromagnetic wave signal expands the reading
