October 1997. The old national regulations for Short Range Devices (SRDs) are thus
being successively replaced by a harmonised European regulation. In the new ver-
sion of February 2002 the REC 70-03 also includes comprehensive notes on national
restrictions for the specified applications and frequency ranges in the individual mem-
ber states of CEPT (REC 70-03, Appendix 3-National Restrictions). For this reason,
Section 5.3 bases its discussion of the national regulations in a CEPT member state
solely upon the example of Germany. Current notes on the regulation of short range
devices in all other CEPT members states can be found in the current version of REC
70-03. The document is available to download on the home page of the ERO ( European
Radio Office ), http://www.ero.dk/EROWEB/SRD/SRD-index.htm.
REC 70-03 defines frequency bands, power levels, channel spacing, and the trans-
mission duration (duty cycle) of short range devices. In CEPT members states that
use the R&TTE Directive (1999/5/EC), short range devices in accordance with article
12 (CE marking) and article 7.2 (putting into service of radio equipment) can be put
into service without further licensing if they are marked with a CE mark and do not
infringe national regulatory restrictions in the member states in question (EC, 1995)
(see also Section 5.3).
REC 70-03 deals with a total of 13 different applications of short range devices at
the various frequency ranges, which are described comprehensively in its own Annexes
(Table 5.2).
REC 70-03 also refers to the harmonised ETSI standards (e.g. EN 300 330), which
contain measurement and testing guidelines for the licensing of radio devices.
5.2.1.1 Annex 1: Non-specific short range devices
Annex 1 describes frequency ranges and permitted transmission power for short range
devices that are not further specified (Table 5.3). These frequency ranges can expressly
also be used by RFID systems, if the specified levels and powers are adhered to.
