General
The present document specifies technical characteristics and methods of measurements for the following equipment
used in ground-based ATC Surveillance for civil air navigation:
• Wide Area Multilateration (WAM) systems with Mode S capabilities which may include Mode A/C,
transmitting at 1 030 MHz and at 1 090 MHz, and receiving at 1 090 MHz, used for air traffic control with or
without 1 090 MHz phase overlay.
The system operates in the frequencies as indicated in Table 1 below.
Table 1: WAM service frequencies
Signals Service frequencies
Interrogation Transmission 1 030 MHz
Reference/Test Transmission 1 090 MHz
Receive 1 090 MHz
Antennas for this equipment are passive.
Remote Field Monitors (RFM) as described in [i.6] as well as Vehicle transmitters as described in [i.7] are not covered
in the present document.
NOTE: The relationship between the present document and essential requirements of article 3.2 of
Directive 2014/53/EU [i.1] is given in Annex A.
The present document specifies technical characteristics and methods of measurements in respect of ElectroMagnetic
Compatibility (EMC) for the following equipment types:
1) digital cellular base station equipment, including BS with antenna ports and BS without antenna ports;
2) repeaters;
3) associated ancillary equipment.
Technical specifications related to conducted emission EMC requirements below 9 kHz on the AC mains port of radio
equipment are not included in the present document.
NOTE 1: Such technical specifications are normally found in the relevant product family standards for AC mains
powered equipment (e.g. EN 61000-3-2 [i.16] and EN 61000-3-3 [i.17]).
Technical specifications related to the antenna port and emissions from the enclosure port of Base Station (BS),
combinations of radio and associated ancillary equipment or repeaters are not included in the present document. Such
technical specifications are found in the relevant product standards for the effective use of the radio spectrum.
The environmental classification and the emission and immunity requirements used in the present document are as
stated in ETSI EN 301 489-1 [1], except for any special conditions included in the present document.
NOTE 2: The relationship between the present document and essential requirements of article 3.1(b) of
Directive 2014/53/EU [i.1] is given in Annex A.
The present document specifies technical requirements, limits and test methods for UWB devices installed in motor and
railway vehicles in the frequency range 6,0 GHz to 8,5 GHz, used for UWB radiodetermination applications.
The present document covers only monostatic radar equipment.
Further details of the covered UWB radiodetermination equipment installed in motor and railway vehicles and the
related EUT categories can be found in clause 4.2 of the present document.
NOTE: The relationship between the present document and essential requirements of article 3.2 of
Directive 2014/53/EU [i.1] is given in annex A.
