Antenna requirements
In addition to the general requirement to use only authorized antennas, the u-blox grant also requires
a separation distance of at least 20 cm from the antenna(s) to all persons. The antenna(s) must not
be co-located with any other antenna or transmitter (simultaneous transmission) as well. If this
cannot be met, a Permissive Change as described below must be made to the grant.
☞
To support verification activities that may be required by certification laboratories, customers
applying for Class-II Permissive changes must implement the setup described in
6.4.5.1
Separation distance
If the required separation distance of 20 cm c
an’t
t be fulfilled, a SAR evaluation must be performed.
This consists of additional calculations and/or measurements. The result must be added to the grant
file as a Class II Permissive Change.
6.4.5.2
Co-location (simultaneous transmission)
If the module is to be co-located with another transmitter, additional measurements for simultaneous
transmission are required. The results must be added to the grant file as a Class II Permissive Change.
6.4.5.3
Adding a new antenna for authorization
If the authorized antennas and/or antenna trace design cannot be used, the new antenna and/or
antenna trace designs must be added to the grant file. This is done by a Class I Permissive Change or
a Class II Permissive Change, depending on the specific antenna and antenna trace design.
•
Antennas of the same type and with less or same gain as those included in
can be added under a Class I Permissive Change.
•
Antenna trace designs deviating from the u-blox reference design and new antenna types are
added under a Class II Permissive Change.
•
For 5 GHz modules, the combined minimum gain of antenna trace and antenna must be greater
than 0 dBi to comply with DFS testing requirements.
⚠
Integrators intending to refer to the u-blox FCC ID / ISED certification ID must
contact
their local
support team to discuss the Permissive Change Process. Class II Permissive Changes are subject
to NRE costs.

Configuration control and software security of end products
☞
“Modular transmitter” hereafter refers to
NORA-W36 series (FCC ID XPYNORAW3).
As the end product must comply with the requirements addressed by the OET KDB 594280
, the
host product integrating the NORA-W36 must comply with the following requirements:
•
Upon request from u-blox, the host product manufacturer will provide all of the necessary
information and documentation to demonstrate how the requirements listed below are met.
•
The host product manufacturer will not modify the modular transmitter hardware.
