3 Definition of terms, symbols and abbreviations
3.1 Terms
For the purposes of the present document, the terms given in ETSI EN 301 489-1 [1] and the following apply:
ancillary equipment: electrical or electronic equipment, that is intended to be used with a receiver or transmitter
NOTE 1: It is considered as an ancillary equipment if:
 the equipment is intended for use with a receiver or transmitter to provide additional operational
and/or control features to the radio equipment (e.g. to extend control to another position or
location);
 the ancillary equipment cannot be used without being connected to radio equipment to provide user
functions independently of a receiver or transmitter; and
 the receiver or transmitter, to which it is connected, is capable of providing some intended
operation such as transmitting and/or receiving without the ancillary equipment (i.e. it is not a
sub-unit of the main equipment essential to the main equipment basic functions).
NOTE 2: An example of ancillary equipment would be a docking station for radio equipment whose interface is
dedicated to a particular product or range of products.
Base Station (BS): alternative name for Central Station
Central Station (CS): two units comprising of:
• the exchange unit, also called Central Controller Station (CCS) - (interface to the local switch); and
ETSI
8 ETSI EN 301 489-4 V3.3.1 (2021-02)
• the radio unit, also called Central Radio Station (CRS) - (central base band/radio transceiver).

the present document either terms are assumed and are completely interchangeable.
operating frequency range: range(s) of radio frequencies covered by the Equipment Under Test (EUT) without any
change of units
Repeater Station (RS): radio repeater outstations with or without subscriber interfaces

6 Draft ETSI EN 301 489-4 V3.3.0 (2020-03)
Introduction
The structure of the ETSI EN 301 489 series has been changed for use under the RED from that used under the
R&TTED. The following text briefly explains this new format:
• The product specific part would contain in clause 7 two new tables similar to that currently in ETSI
EN 301 489-1 [1] clause 7.1 for emissions and clause 7.2 for immunity. These would inform the reader
whether the requirements, etc. are to be found in ETSI EN 301 489-1 [1] or further in the product specific part.
As an example; the assessment of a Wi-Fi router would use ETSI EN 301 489-17 [i.12] which would normatively
reference ETSI EN 301 489-1 [1] for certain aspects. Consequently:
• Changes to ETSI EN 301 489-1:
No references to product specific parts.
• Changes to product specific parts, e.g. the present document:
Two new tables, one for emissions in clause 7.1, and one for immunity in clause 7.2 that will point the reader
to the location of the requirements, i.e. ETSI EN 301 489-1 [1] or the present document.

3 Definition of terms, symbols and abbreviations
3.1 Terms
For the purposes of the present document, the terms given in ETSI EN 301 489-1 [1] and the following apply:
ancillary equipment: electrical or electronic equipment, that is intended to be used with a receiver or transmitter
NOTE 1: It is considered as an ancillary equipment if:
 the equipment is intended for use with a receiver or transmitter to provide additional operational
and/or control features to the radio equipment (e.g. to extend control to another position or
location);
 the ancillary equipment cannot be used without being connected to radio equipment to provide user
functions independently of a receiver or transmitter; and
 the receiver or transmitter, to which it is connected, is capable of providing some intended
operation such as transmitting and/or receiving without the ancillary equipment (i.e. it is not a
sub-unit of the main equipment essential to the main equipment basic functions).
NOTE 2: An example of ancillary equipment would be a docking station for radio equipment whose interface is
dedicated to a particular product or range of products.
Base Station (BS): alternative name for Central Station
Central Station (CS): two units comprising of:
• the exchange unit, also called Central Controller Station (CCS) - (interface to the local switch); and
ETSI

• the radio unit, also called Central Radio Station (CRS) - (central base band/radio transceiver).
NOTE: In some deployments the term Base Station is also used in place of Central Station. For the purposes of
the present document either terms are assumed and are completely interchangeable.
operating frequency range: range(s) of radio frequencies covered by the Equipment Under Test (EUT) without any
change of units
Repeater Station (RS): radio repeater outstations with or without subscriber interfaces
Terminal station (TS): outstations with subscriber interfaces
