The present document applies to Close Range Inductive Data transmitters and receivers operating at 13,56 MHz.
The present document contains the technical characteristics for radio equipment and is referencing in
CEPT/ERC Recommendation 70-03 [1] and ERC Decisions.
The present document does not necessarily include all the characteristics which may be required by a user, nor does it
necessarily represent the optimum performance achievable. It is a specific product standard covering specific close
range inductive data equipment:
- with an inductive loop antenna;
- with an antenna connection and/or with an integral antenna;
- for alarms, identification systems, telecommand, telemetry, etc.
When selecting new applications, which may have inherent safety of human life implications, manufacturers and users
should pay particular attention to the potential for interference from other systems operating in the same or adjacent
bands.
The present document covers fixed stations, mobile stations and portable stations. If a system includes transponders,
these are measured together with the transmitter.
All types of modulation for radio devices are covered by the present document, provided the requirements of clause 7
are met.
The radio equipment, covered by the present document has a maximum radiated field strength given in table 1.
Table 1: Maximum radiated H-field at 13,56 MHz
On non-harmonized parameters, national administrations may impose conditions on the type of modulation, frequency,
channel/frequency separations, maximum transmitter radiated field strength/maximum output current to a defined
antenna, duty cycle, equipment marking and the inclusion of an automatic transmitter shut-off facility, as a condition for
the issue of an individual or general licence, or as a condition for use under licence exemption.
Two types of measuring methods are defined in the present document due to the varied nature of the types of equipment
used in this band. One method measures the radiated H-field and the second the radiated power.
The present document covers requirements for radiated emissions below as well as above 30 MHz.
Additional standards or specifications may be required for equipment such as that intended for connection to the Public
Switched Telephone Network (PSTN).
