QI SPECIFICATION VERSION 2.0 –
Part 2: Glossary
FOREWORD
 The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprisingall
national electrotechnical committees (IEC National Committees). The object of IEC is to promote internationalco-
operation on all questions concerning standardization in the electrical and electronic fields. To this end andin addition
to other activities, IEC publishes International Standards, Technical Specifications, TechnicalReports, Publicly
Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Theirpreparation is entrusted to
technical committees; any IEC National Committee interested in the subject dealt withmay participate in this
preparatory work. International, governmental and non-governmental organizationsliaising with the IEC also
participate in this preparation. IEC collaborates closely with the InternationalOrganization for Standardization
(ISO) in accordance with conditions determined by agreement between the twoorganizations.
 The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
 IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
 In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence betweenany IEC
Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
 IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
 All users should ensure that they have the latest edition of this publication.
 No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage orother
damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) andexpenses
arising out of the publication, use of, or reliance upon, this IEC Publication or any other IECPublications.
 Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
 IEC draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). IEC takes no position concerning the evidence, validity or applicability of any claimed patent rights inrespect
thereof. As of the date of publication of this document, IEC Kad notreceived notice of (a) patent(s),which may be
required to implement this document. However, implementers are cautioned that this may notrepresent the latest
information, which may be obtained from the patent database available athttps://patents.iec.ch. IEC shall
not be held responsible for identifying any or all such patent rights.
IEC 635-2 has been prepared by technical area 15: Wireless Power Transfer, of IEC
technical committee 100: Audio, video and multimedia systems and equipment. It is an
International Standard.
It is based on Qi Specification version 2.0, Glossary and was submitted as a Fast-Track
document.
The text of this International Standard is based on the following documents:

which submitted it.
This document was developed in accordance with ISO/IEC Directives, Part 1 and ISO/IEC
Directives, IEC Supplement available at www.iec.ch/members_experts/refdocs. The main
document types developed by IEC are described in greater detail at www.iec.ch/publications.

1 Definitions
ActiveArea: The part of the Interface Surface of a Power Transmitter Product or
Power Receiver Product through which a sufficiently high magnetic flux
penetrates when the Power Transmitter Product is providing power to
the Power Receiver Product.
AirGap: The distance between the top surface of a Power Transmitter Product
and the bottom surface of a Power Receiver Product.
NOTE: The Air Gap also comprises any additional spacing between a Power
Transmitter Product and a Power Receiver Product introduced by accessories
added by a user to either product.
AnalogPing: A short-duration Power Signal applied by a Power Transmitter with the
purpose of detecting the presence of an object, without waking up a

Power Transmitter.
BaselinePowerProfile:A supported Power Profile.
BaselineProtocol: The communications protocol introduced in version 1.0 of the
QiSpecification.
Certificate: A digital form of identification that provides information about a
Certificate Authority, a manufacturer, or a Power Transmitter Product
Unit, and certifies ownership of a public key.
CertificateAuthority: An organization that issues Certificates.
CertificateChain: A series of two or more Certificates where each Certificate is signed by
the owner of the preceding Certificate in the chain.
