GHz avoids interference from water and the metal, and thus
is typical for irrigation, greenhouse or cold chain applications.
Low-Frequency tags use less power and are better able to penetrate
non-metallic substances. In general, the higher the frequency,
the longer the communication range, and the faster the communication,
this means that more data can be transmitted. In near field
applications where is possible to have lots of tags it might be better
to have a tag with low read range to avoid false positive reads. In
other applications, like crop monitoring, it is better to choose a
long read range to optimize the read performance
