42 Hardware Overview
Authorized Antennas
This device has been designed to operate with the antennas listed below, and having a maxi-
mum gain of 8.15dBiL. Antennas not included in this list or having a gain greater than 8.15
dBiLare strictly prohibited for use with this device without regulatory approval. (Circularly polar-
ized antennas can have a circular gain has high as 11.15 dBiC and still maintain a maximum lin-
ear gain of 8.15 dBiL.) The required antenna impedance is 50 ohms.
ThingMagic Nano Authorized Antennas
Note: Most tags are linearly polarized, so the “max linear gain” value is the best number to use
when calculating the maximum read distance between the module and a tag.
FCC Modular Certification Considerations
Trimble has obtained FCC modular certification for the ThingMagic Nano module. This
means that the module can be installed in different end-use products by another
equipment manufacturer with little or no additional testing or equipment authorization for
the transmitter function provided by that specific module. Specifically:
No additional transmitter-compliance testing is required if the module is operated with
one of the antennas listed in the FCC filing
No additional transmitter-compliance testing is required if the module is operated with
the same type of antenna as listed in the FCC filing as long as it has equal or lower
gain than the antenna listed. Equivalent antennas must be of the same general type
(e.g. dipole, circularly polarized patch, etc.), must be of equal or less gain than an
