antenna previously authorized under the same FCC ID, and must have similar in
band and out of band characteristics (consult specification sheet for cut-off
frequencies).
If the antenna is of a different type or higher gain than those listed in the moduleΚΌs FCC
filing, see ThingMagic Nano Authorized Antennas
, a class II permissive change must be
requested from the FCC. Contact us at support@thingmagic.com and we can help you

The FCC regulations state that a host device using a module that has a modular grant
can:
1. Be marketed and sold with the module built inside that does not have to be end-user
accessible/replaceable, or
2. Be end-user plug-and- play replaceable.
In addition, a host product is required to comply with all applicable FCC equipment
authorizations, regulations, requirements and equipment functions not associated with
the RFID module portion. For example, compliance must be demonstrated to regulations
for other transmitter components within the host product; to requirements for unintentional
radiators (Part 15B), and to additional authorization requirements for the non-transmitter
functions on the transmitter module (for example, incidental transmissions while in
receive mode or radiation due to digital logic functions).
To ensure compliance with all non-transmitter functions the host manufacturer is
responsible for ensuring compliance with the module(s) installed and fully operational.
For example, if a host was previously authorized as an unintentional radiator under the
Declaration of Conformity procedure without a transmitter certified module and a module
is added, the host manufacturer is responsible for ensuring that the after the module is
installed and operational the host continues to be compliant with Part 15B unintentional
radiator requirements. Since this may depend on the details of how the module is
integrated with the host, we shall provide guidance to the host manufacturer for
compliance with Part 15B requirements.
