Subject:
Representing equipment classes in the new single multipart standard
1. Issue
Representation of equipment options in the new ETSI multipart standard to replace existing
equipment classes shown in the scope of base standards.
This unique identifier would form part of the notification identifier for equipment type
declaration to notified bodies under the R&TTE Directive. It could also serve as a transparent
equipment reference code in the radio interface requirement and national licensing regimes.
2. Background
The 2nd Steering Committee (SC#2) of STF 190, held on the 16th January 2002, discussed
using a new single equipment identifier for unique equipment identification in the new
multipart standard. The UK Radio Interface Requirement was cited as a possible example.
However, this needs additional parts if it is to uniquely identify the equipment type. Below is a
possible labelling scheme.
3. Proposal
Different equipment classes could be represented alphanumerically in the format:
FF-fG/BBBMxn/CCC-ccM/LLL-MOD/PPPP

where ‘FF-f’ is a three digit number (1 d.p.) which uniquely identifies frequency, i.e. 1.4
GHz, 7.5 GHz and 38 GHz would be respectively labelled 1-4G, 7-5G and 38-0G. The
bold character G denotes GHz.

where ‘BBB’ is a three digit number which uniquely identifies digital payload bit-rate, i.e.
2Mbit/s, 34Mbit/s, 140MBit/s would be respectively 002M, 034M and 140M. The bold
character M (k) denotes Mbit/s (kbit/s). The ‘xn’ shown in bold italics represents an
optional part specifically for n–times bit rates, i.e. 2 x 2, 8 x 2 and 34 x 2 would be
respectively labelled 002Mx2, 008Mx2 and 034Mx2.

where ‘CCC-cc’ is a five digit number (2 d.p.) which uniquely identifies channel spacing,
i.e. 1.75 MHz, 3.5 MHz, and 56 MHz would be respectively 001-75M, 003-50M and 05100M. The bold character M (k) denotes MHz (kHz).

where ‘LLL-MOD’ is a 6 alphanumeric character which represents modulation scheme.
‘LLL’ is a three digit number for number of states. ‘MOD’ is a three-character string for
modulation type. Therefore 4-FSK, 8-PSK, 32-QAM and 128 TCM would be respectively
labelled 004-FSK, 008-PSK, 032-QAM and 128-TCM. Note that QPSK can be simply
labelled as 004-PSK.

where ‘PPPP’ is an optional alphanumeric string used to identify spectrum polarisation
usage, i.e. Adjacent Channel Co-Polarisation, Adjacent Channel Alternate-Polarisation,
and Co-Channel Dual Polarisation would be respectively ACCP, ACAP and CCDP etc.
