The MRF24WB0MA/MRF24WB0MB module has been
certified for use in European countries. The following
testing has been completed:
Test standard ETSI EN 300 328 V1.7.1 (2006-10):
• Maximum Transmit Power
• Maximum EIRP Spectral Density
• Frequency Range
• Radiated Emissions
Test standards ETSI EN 301 489-1:2008 and ETSI EN
301 489-17:2008:
• Radiated Emissions
• Electro-Static Discharge
• Radiated RF Susceptibility
The modules are fully compliant with
• Radiated Emissions EN 55022
• Electrostatic Discharge EN 61000-4-2
• Radiated Immunity EN 61000-4-3
• EN 60950-1
• CE-Mark
• RoHS
ETSI does not provide a modular approval similar to
the USA (FCC) and Canada (IC). However, the testing
completed above can be used as part of the customer’s
application for certification. The test report data can be
included in their test plan and can significantly the
lower customer’s certification burden.
A helpful document that can be used as a starting point
in understanding the use of Short Range Devices
(SRD) in Europe is the European Radio Communica-
tions Committee (ERC) Recommendation “70-03 E”,

“If the device contains digital circuitry that is not
directly associated with the radio transmitter, the
device shall also have to comply with ICES-003,
Class A or B as appropriate, except for ICES-003
labeling requirements. The test data obtained (for
the ICES-003 tests) shall be kept by the manufac-
turer or importer whose name appears on the
equipment label, and made available to Industry
Canada on request, for as long as the model is
being marketed in Canada.”

Wi-Fi Alliance Certification focuses on interoperability
testing of devices based on 802.11 standards.
Historically, when the certification process and pro-
grams were developed by Wi-Fi Alliance members, the
vast majority of the 802.11 clients were PC-centric, and
certification testing adequately addressed those types
of devices. In subsequent years, the number of Wi-Fi
devices that are not PC-centric has grown significantly.
These non-standard devices, as a class of products,
have been dubbed Application Specific Devices
(ASDs) by the Wi-Fi Alliance. ASDs are 802.11
devices, e.g., clients or access points (APs), which
cannot be tested under a standard Alliance test plan
because they do not comply with the standard test con-
figuration and/or because they are designed to perform
a specific application. Examples include, but are not
limited to: bar code scanners, pagers, recording
devices, monitoring equipment, and cable modems.
The APs or clients that are used to validate ASD com-
pliance (from the standard test bed) will meet all of the
requirements specified in the applicable System
Interoperability Test Plans (referred to as the “standard
test
MRF24WB0MA and MRF24WB0MB modules are in
the ASD category.
The modules are certified under Wi-Fi 802.11 with
WPA2, WPA, and WEP System Interoperability ASD

and g Devices (Version 1.0).
