3.4 Other Regulatory Jurisdictions
Should other regulatory jurisdiction certification be
required by the customer, or the customer need to
recertify the module for other reasons, a certification
utility is available. The utility runs on a Window's PC
and utilizes a USB to SPI converter to interface to the
MRF24WG0MA/MB module. In order to use the utility,
the MRF24WG0MA/MB module must be out of reset
and not accessed by the system host. That is, the SPI
signals to the MRF24WG0MA/MB module must be tri-
state, with Reset and Hibernate deasserted. The fol-
lowing signals will need to be brought from the
MRF24WG0MA/MB module for connection to the PC
(through the USB adapter):
• SDO
• SDI
• CS
• SCK
• INT
• GND
For further regulatory Certification Utility and
documentation, contact your local Microchip
salesperson.

3.5 Wi-Fi^® Alliance
Wi-Fi Alliance Certification focuses on interoperability
testing of devices based on 802.11 standards.
Historically, when the certification process and
programs 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, for example clients or access points (APs),
which cannot be tested under a standard Alliance test
plan because they do not comply with the standard test
configuration 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
compliance (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 plan”), unless specifically exempted. The
MRF24WG0MA/MB modules are in the ASD category.
The modules are certified under Wi-Fi 802.11 with ASD
Model Test Plan with Test Engine For IEEE 802.11a, b,
and g Devices (Version 1.0).
