ElectroMagnetic Compatibility (EMC) standard for radio equipment and services - Part 50: Specific conditions for Cellular Communication Base Station (BS), repeater and ancillary equipment - Harmonised Standard for ElectroMagnetic Compatibility
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.
Including individual and combinations of technologies listed in table 1.
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.
Standard elektromagnetne združljivosti (EMC) za radijsko opremo in storitve - 50. del: Posebni pogoji za ponavljalniško (repetitorsko) in pomožno opremo celičnih komunikacijskih baznih postaj (BS) - Harmonizirani standard za elektromagnetno združljivost
Ta dokument določa tehnične lastnosti in merilne metode v zvezi z elektromagnetno združljivostjo (EMC) za naslednje vrste opreme: 1) digitalna oprema celičnih baznih postaj, vključno z baznimi postajami z antenskimi vhodi in brez njih; 2) ponavljalniki; 3) povezana pomožna oprema. Vključene so tudi posamezne tehnologije, navedene v preglednici 1, in njihove kombinacije. Ta dokument ne vključuje tehničnih specifikacij, ki se navezujejo na zahtevano oddajanje prevajanih motenj v zvezi z elektromagnetno združljivostjo pod 9 kHz pri konektorju izmeničnega napajanja radijske opreme. OPOMBA 1: Te tehnične specifikacije so običajno navedene v ustreznih standardih skupin izdelkov za opremo, priključeno v izmenično električno omrežje (npr. EN 61000-3-2 [i.16] in EN 61000-3-3 [i.17]). Ta dokument tudi ne vključuje tehničnih specifikacij v zvezi z antenskim vhodom in sevanjem iz vhoda na ohišju bazne postaje, kombinacijami povezane pomožne opreme oziroma ponavljalniki. Takšne tehnične specifikacije so navedene v ustreznih standardih za izdelek na področju učinkovite uporabe radijskega spektra. Okoljska razvrstitev ter zahteve glede sevanja in odpornosti iz tega dokumenta so navedene v standardu ETSI EN 301 489-1 [1], razen posebnih pogojev iz tega dokumenta. OPOMBA 2: Razmerje med tem dokumentom in bistvenimi zahtevami člena 3.1(b) Direktive 2014/53/EU [i.1] je podano v dodatku A.

CDMA-PAMR: Public Access Mobile Radio system based on CDMA Spreading Rate 1 specifications
channel bandwidth: RF bandwidth supporting a single E-UTRA RF carrier with the transmission bandwidth
configured in the uplink or downlink of a cell
NOTE: The channel bandwidth is measured in MHz and is used as a reference for transmitter and receiver RF
requirements.
downlink: unidirectional radio link for the transmission of signals from a UTRAN access point to a UE
hybrid AAS BS: AAS BS which has both a conducted RF interface and a radiated RF interface in the far field and
conforms to a hybrid requirements set
NOTE: For NR operation in MSR, a hybrid AAS BS corresponds to NR type 1-H.
hybrid requirements set: complete set of requirements applied to a hybrid AAS BS with both conducted and radiated
requirements
International Mobile Telecommunications-2000 (IMT-2000): third generation mobile systems which provide access,
by means of one or more radio links, to a wide range of telecommunications services supported by the fixed
telecommunication networks (e.g. PSTN, ISDN or IP), and to other services which are specific to mobile users
License Assisted Access (LAA): License Assisted Access LTE based base station operating in unlicensed frequency
spectrum
maximum throughput: maximum achievable throughput for a reference measurement channel
MB Base Station: base station which is characterized by the ability of its transmitter and/or receiver to process two or
more carriers in common active RF components simultaneously, where at least one carrier is configured at a different
non-overlapping operating band than the other carrier(s)
MSR Base Station: base station which is characterized by the ability of its receiver and transmitter to process two or
more carriers in common active RF components simultaneously in a declared RF bandwidth, where at least one carrier
is of a different RAT than the other carrier(s)
multiple unit BS: radio base station consisting of separate radio digital unit and the radio unit
NOTE: See figure 1a.
NB-IoT guard band operation: operation of NB-IoT guard band utilizing the unused resource block(s) within an
E-UTRA carrier's guard-band
NB-IoT In-band operation: operation of NB-IoT in-band utilizing the resource block(s) within a normal E-UTRA
carrier
ETSI
13 ETSI EN 301 489-50 V2.4.1 (2025-09)
NB-IoT standalone operation: operation of NB-IoT standalone utilizing its own spectrum, for example the spectrum
currently being used by GERAN systems as a replacement of one or more GSM carriers, as well as scattered spectrum
for potential IoT deployment
operating band: frequency range in which a wireless service operates (paired or unpaired), that is defined with a
specific set of technical requirements
OTA AAS BS: AAS BS which has ≥ 8 transceiver units for E-UTRA or MSR and ≥ 4 transceiver units for UTRA per
cell and has a radiated RF interface only and conforms to the OTA requirements set
NOTE: OTA AAS BS has no accessible antenna port. See figure 1c. For NR operation in MSR, an OTA AAS BS
corresponds to an NR type 1-O BS.
OTA requirements set: complete set of OTA
