9 Regulatory Considerations
The microNode uses a castellation for its RF port. This lowers the unit cost and provides greater
host configuration flexibility in the final application. On-Ramp Wireless has obtained modular
certifications (FCC, IC, ETSI, Japan and others) for the microNode. The existence of the modular
certification minimizes cost and time to market for our customers. The certification documents
and the results of the certification tests are available to system integrators upon request.
The modular certification of the microNode can be re-used by customers that utilize an
equivalent layout and stack-up as our reference design platform known as the reference
Application Communication Module (rACM). In doing so, the customer must use the same RF
path to the antennas as does rACM, that is, 50 Ohm traces, SPDT RF switch, and antennas of the
same type with gain less than or equal to the approved antennas. Additional testing for
verification purposes may still be required per FCC or other regulatory body guidelines and
requirements but will vary on a case-by-case basis. Customers are advised to consult with the
regulatory compliance test house of their choice for the best way to proceed. For details about
the rACM, refer to the rACM Developer Guide (010-0105-00).
Additionally, On-Ramp Wireless has prepared certification guidelines on how to use the
software and system tools required for certification. Some markets (such as FCC/IC) are fairly
straight forward for certification and are largely TX Spectrum-based. Other markets may require
a much more sophisticated FER process involving an Access Point and Quick Start System. These
procedures are defined in the document entitled EMC Compliance Guide (010-0037-00). This
document also includes hints and recommendations to help make the process as easy as
possible. For more information about this document, see section 1.3: Referenced Documents.

Some regulatory domains require a block diagram of the module for their documentation similar
to that shown in the following figure.
