This consensus standard specifies methods, instrumentation, and facilities requirements for measurement of
radio-frequency (RF) signals and RF noise emitted from unlicensed wireless devices. It does not include
generic nor product-specific emission limits. Measurement methods are provided for radiated and
conducted emissions that can be generated by a variety of devices, as described below. This standard does
not consider test methods for unlicensed wireless devices already covered in other published standards,
such as Unlicensed Personal Communication Services (UPCS) devices, which are covered in ANSI C63.17
[B1].1 In addition, many types of wireless devices are also subject to regulatory requirements concerning
human exposure to RF energy; RF exposure conformity assessment methods are not considered in this
standard, but are the subject of other standards, e.g., IEEE Std 1528™-2003 [B22].
This document provides standard test methods for determining compliance with regulatory requirements
for many types of wireless devices. These unlicensed wireless devices include but are not limited to the
following:
- Remote control and security unlicensed wireless devices
- Frequency hopping and direct sequence spread spectrum devices
- Anti-pilferage devices
- Cordless telephones
- Radio frequency identification (RFID) tag readers⎯ Unlicensed National Information Infrastructure devices
- Intrusion detectors
- Unlicensed wireless devices operating below 30 MHz
- Wireless (garage) door openers
- Ultra-wideband (UWB) devices
- Automatic vehicle identification systems
- Other devices, e.g., with operations authorized under Part 15 of the FCC Rules and Regulations (47
CFR Part 15).2
Clause 2 and Clause 3 contain the normative references and definitions used in this standard, respectively.
Clause 4 provides the specifications for the necessary test instrumentation needed for performing
compliance testing. Clause 5 provides the general requirements for all standard test methods. Clause 6
provides standard test methods required for most unlicensed wireless devices. Clause 7 identifies additional
tests or requirements for specific unlicensed wireless devices. Clause 8 specifies requirements for reporting
test results, with special emphasis on the use of guidance from ISO/IEC 17025:2005.
Annex A is an informative listing of the tests required to show compliance of a specific unlicensed wireless
device. Because Annex A describes regulatory requirements for testing of unlicensed wireless devices, it
serves as a key to use of this standard. Annex B is an informative example of the information to be included
in a test report. Annex C is an informative discussion on instrumentation pulse desensitization
considerations. Annex D provides information about detector types and functions used in EMC testing.
Annex E and Annex F provide an informative glossary and related reading (bibliography), respectively.
Use of the annexes and clauses applicable to a wireless device under test allows users of this standard to
determine compliance of a device to national regulatory requirements. However, any test procedure
identified for use by the national regulatory authority that differs from the provisions of this standard shall
take precedence.
Numbered cross-references used throughout this standard refer to either a specific clause or subclause of
this standard; e.g., 6 refers to Clause 6, 6.2 refers to subclause 6.2, and A.2 refers to subclause A.2 of
Annex A.
