This application note discusses the necessary information for you to use a WirelessUSB™ LP radio in a product
intended for the Japanese market. WirelessUSB-based systems require a certification to market the product to make
certain that it meets international regulations and national laws. This application note serves as a reference point in
selecting a WirelessUSB LP radio for your application needs. The use of a Cypress radio chip and its suitability for
Japanese product development is demonstrated by providing the compliance data on a reference development kit.

Introduction
One of the problems that product developers encounter in
incorporating any radio communication device is tackling
the legal aspect of qualifying the products and marketing
them without legal problems. This application note
demonstrates the performance of the WirelessUSB radio
chip CYRF6936 against Japanese requirements by
submitting a reference radio development kit to meet the
Japanese requirements.
Purpose
This application note gives you an overview of the legal
issues governing the manufacture and sale of wireless
products intended for unlicensed operation in Japan.
Although the operation of wireless radio devices in the
ISM band (2.4 to 2.5 GHz) is license-free, products
incorporating a WirelessUSB radio chip must be typecertified or meet certain requirements. In Japan, the
Ministry of Internal Affairs and Communication is
responsible for the regulation of all wireless radio devices.
Japanese Authorization Process Radio Law
The Japanese Radio Law provides rules for product
development using wireless devices.

WirelessUSB™ LP RDK Japanese Radio Law Testing and Verification
Type Certification (Radio Law Article 38-17)
Testing is conducted on one sample unit for each type of
radio equipment applying for certification. An example of
this type of testing is that done by the Registered
Certification Body System (Radio Law Article 38-17)
shown in Figure 1.
In this system, a person registered by the Ministry of
Internal Affairs and Communications conducts an
inspection of radio equipment under foreign statue and
makes an application certifying that the specified radio
equipment complies with technical standards of the Radio
Law for use in Japan.
The WirelessUSB LP reference design kit (RDK) CY4672
was verified in this way to fulfill Japanese compliance by
D.S.P. Research, one of the registered certification bodies
in Japan.
The WirelessUSB LP RDK has a precertified chip set and
reference designs certified by D.S.P. Research.
D.S.P.Research enables you to waive the regular
compliance procedure on your devices built with
WirelessUSB LP RDK. Contact the sales department of
D.S.P.Research ([email protected]).

WirelessUSB™ LP RDK Japanese Radio Law Testing and Verification
The Japanese Radio Law testing requirements and a brief
overview of the required tests are described in the
following section.
Mouse with Input Power 3.0 V
The tests are as follows:






Frequency tolerance
Occupied bandwidth and spread bandwidth
Transmission output power
Spurious emission strength
Secondarily emitted radio wave strength
Burst ratio
The RDK consists of a mouse, keyboard, and a dongle.
The mouse and keyboard are tested at two supply
voltages and the dongle is tested at a single supply
voltage.
Measurement Details
This application note documents the measurements and
data collected on the RDK - mouse, keyboard, and dongle
using the WirelessUSB LP chip. This is used to verify that
the radio module meets the Japanese regulation.
The Japanese Radio Law testing was performed at the
DSP Research test facility on a Cypress RDK.
1.
The mouse, keyboard, and dongle are tested
individually.
2.
The mouse, keyboard, and dongle are installed with
EMC Test code to exercise the radio in singlefrequency transmit mode. The mouse, keyboard, and
dongle are set up to transmit continuously at lowest,
middle, and highest frequency channels.
3.
Performed all the tests required by Japanese Radio
Law at lowest channel at 2402 MHz, mid channel at
2439 MHz and highest channel at 2479 MHz. All
measurements are taken with the power level set at 7.

WirelessUSB™ LP RDK Japanese Radio Law Testing and Verification
Summary
The Japanese radio law (RF) on the reference
development kit is tested and verified. The equipment
under test (EUT) passed all the tests required by
Japanese Radio law to meet Japanese Government
certification requirements. This application note provides
an overview of the wireless product compliance process
for radio equipment technical requirement in Japan. It also
serves as a guideline for selecting the Cypress’s
WirelessUSB™ LP radio system chip to wireless
application solutions. The Japanese electromagnetic
compatibility (EMC) is not mandatory and is served
voluntary guideline by VCCI (www.vcci.or.jp).
