of the REC 70-03 into national legislation. Here, too, national restrictions (e.g. lower
power level in some frequency ranges below 135.00 kHz) should be taken into consid-
eration.
All radio systems that have a German licence or were put into operation in accor-
dance with the provisions of Directive 1999/5/EC (R&TTE Directive), and are marked
accordingly (CE marking), may be operated. Of course, national restrictions must still
be adhered to.
The licensing of inductively coupled RFID systems is regulated in decree
61/2000, entitled 'Allgemeinzuteilung von Frequenzen fur die Benutzung durch die
Allgemeinheit fur induktive Funkanlagen des nichtoffentlichen mobilen Landfunks
(nomL)' ('General allocation of frequencies for use by the general public for inductive
radio systems relating to private mobile national radio'). General allocation covers
numerous applications of inductive radio systems, such as lorry barriers (RFID), EAS,
traffic control systems, metal detectors, recognition systems for people, animals and
goods (RFID), but also data and voice transmission over short distances (e.g. for alarm
systems). See Figure 5.6.
Only the frequency ranges listed in Table 5.14 may be used for the above-mentioned
radio applications.
The licensing of RFID systems in the frequency ranges up to 24 GHz is regulated in
decree 73/200 entitled 'Allgemeinzuteilung von Frequenzen fur die Benutzung durch
die Allgemeinheit fur Funkanlagen geringer Leistung des nichtoffentlichen mobilen
Landfunks (nomL) in ISM Frequenzbereichen; SRD (Short Range Devices)' ('General
allocation of frequencies for use by the general public for low power radio systems
relating to private mobile national radio in ISM frequency ranges; SRD (Short Range
