Executive summary
The present document analyses the potential and status of 13,56 MHz RF Identification Systems and the need for
regulatory and standard improvements as:
• 13 MHz RFID systems cover the widest range of markets and applications among the RFID families, this is
detailed in clause 6.1 and annex A.
• The prospects for the next decade for the 13,56 MHz RFID technology is that these RFIDs have the highest
turnover and increase rate compared to other frequencies. The rate is estimated for about 50 % or higher of all
SRD applications. This is based on:
- the mature and versatile 13,56 MHz technology is providing either large reading range with high data
rates and bulk reading capability or very high data rates at low reading ranges needed for the required
safety and security features and as requested by the EC mandate M436 for private/public and commercial
use;
- 13,56 MHz systems are used in a large amount of installed systems covering various markets. The
present document covers two different application types which require different TX emission masks for
different emission levels and bandwidths:
a) Narrowband/long range applications as used in libraries, access control, logistics and materials
handling, waste management, apparel tagging in manufacturing laundry services, etc. These
systems are typically installed in industrial or shopping sites. From all 13,56 MHz applications they
represent some 3 % of all deployed systems.
b) Wideband/short range applications for use in ticketing and payment systems to secure transactions
(i.e. smart cards, e-Passport, mass transportation tickets), NFC, employing authentication to
provide secure identification mechanisms for persons and objects. These systems represent about
97 % of the market for 13,56 MHz RFID systems.
- All 13,56 MHz RFID systems feature unique properties as highest spectrum efficiency as dense
operation of 13,56 MHz RFID systems in a given area.
• 13,56 MHz frequency band is harmonized in all three ITU regions which assures coverage of all markets.
Furthermore recent developments in the evolution of the technology and ISO standards as well as market developments
or requirements in social, public, commercial and industrial areas have shown the need for amending the
ERC/REC 70-03, annex 9 as well as amending the EN 300 330-1 [i.2] as presented in the present document.

Introduction
The present document has been developed to support the co-operation between ETSI and the Electronic
Communications Committee (ECC) of the European Conference of Post and Telecommunications Administrations
(CEPT) for internal reference within ETSI [i.1].
RFIDs have been in use for almost all areas of the industrial-commercial, the public and private sector.
Especially the 13,56 MHz RFID technology is matured and has achieved tag deployment rates in the several billion unit
range. This frequency is highly attractive because of the global harmonization of this frequency band since it is an ISM
band in all 3 ITU regions.
The 13,56 MHz RFIDs use the inductive near field propagation mode which has the unique advantage of allowing a
high reader field strength without disturbing the in-band or adjacent band radio services because of the fast field
strength roll-off of 60 dB/Decade [i.2] and [i.5].
This means that the reading range is confined or limited while RFID's using EM/far-field operation can suffer from
reflections and diffractions.
The two most limiting factors for 13,56 MHz RFIDs are regulatory constraints with regard to the modulation allowance
level which is addressed in the present document.

5 Background information
5.1 The current situation
RFIDs operating at 13,56 MHz meet a number of different market requirements and have reached the highest market
acceptance and penetration among all other RFID technologies operating at other frequency ranges.
The increase rate over the next decade is about 50 % or higher. This is based on an already high level of installed
systems and particularly the number of tags. This high level of acceptance is due to the versatile yet simple 13,56 MHz
inductive technology.
13,56 MHz benefits are:
• Frequency band is harmonized in ITU regions 1, 2 and 3
• Near field properties RFIDs have distinct features well defined and limited operating range
• Very high spectrum efficient technology 13,56 MHz ±7 kHz is sufficient
• High coverage of Standards by global standards (ISO) and regional as
 well as different application specific
 standards
• Highest data rate and bidirectional communications up to 423 kB/s for sophisticated, secure
 data transmission and anti-collision and up
 to 30 MB/s for short distance systems
• Low cost structure using mature and high volume technologies
• Choice of technology for or short or long operating ranges at very high or high data rates
Regarding the achievable operating range, the regulation for the carrier field strength level was increased from
42 dBµA/m to 60 dBµA/m a few years ago in order to provide higher reading ranges and to meet the market demands.
At the time, the market primarily required read-only tags and the achievable high reading range was effectively enabled
by the 60 dBµA/m limit.
The increased complexity of RFID systems, the level of sophistication of the various applications, last but not least the
need for data protection and enhanced capability for data security have dictated the shift from read-only and
unidirectional data communication to bidirectional communication between reader and the tag. New applications
necessitate the bandwidth increase from ±900 kHz to ±7 MHz.
Bidirectional communication to the tags is essential for present RFID systems with sophisticated protocols e.g. for
addressing individual tags, and also enabling data security functions. For bulk reading environments fast protocols for
tag serialization is required, which is only feasible with bidirectional communication.
The large majority of the RFID systems respectively the tags are passive, this is a precondition for high market
penetration and reliable operation at low cost. Passive tags face a number of limitations for realizing the chip
technology, especially if bidirectional communication between reader and tag is required.
The bidirectional communication requires that the tag activation signal is to be ASK or PSK modulated. The ASK
modulation level has to be minimum ~10 % (respectively a modulation index of 18 %) in order to be reliably detected
by the passive tags.
The present modulation mask, initially defined for operation at a carrier level of 42 dBµA/m, works satisfactorily with
the present modulation mask level of 9 dBµA/m. However using the increased carrier level of 60 dBµA/m the
modulation level of 9 dBµA/m is too low.
The present document supports the need for amending the modulation emission levels and defines the required
modulation mask to allow reliable bidirectional communication at the carrier operation level of 60 dBµA/m.
The present modulation mask, initially defined for operation at a carrier level of 42 dBµA/m, works satisfactorily with
the present modulation mask level of 9 dB/µA/m but with the increased carrier level the modulation level is too low and
no longer functional to support bidirectional communication at 60 dBµA/m.

The present document supports the need for amending the modulation emission levels and defines the required
modulation mask to support bidirectional communication at the operation level of 60 dBµA/m.
5.2 The 13,56 MHz inductive RFID technology
• RFID systems at 13,56 MHz basically operate as magnetically coupled and tuned circuits.
• Systems can use the design trade-off potential to either make use of high quality factors (Q) for the antenna
circuits in order to provide the highest efficiency to power the tags over the maximum required reading
distance at moderate data rates, or using a lower Q and broadband tuned circuits supporting high data rates up
to 100 kBit/s resulting in lower ranges.
• A distinct advantage of the 13,56 MHz technology is the fact that 13,56 MHz RFID systems operate in the
near field propagation domain which features:
- high field strength roll-off of ~60 dB/decade [i.2] and [i.5];
- lower interference potential to other services operating in the same or nearby frequency bands [i.3] and
[i.6];
- the re-use of the frequency band allowing high spectrum efficiency as dense operation of 13,56 MHz
RFID systems in a given area;
