Introduction
The present document is part of a set of standards developed by ETSI that are designed to fit in a modular structure to
cover radio equipment within the scope of the Radio Equipment Directive [i.1]. The present document is produced
following the guidance in ETSI EG 203 336 [i.3] as applicable.

ETSI
9 ETSI EN 301 908-14 V17.1.1 (2025-02)
1 Scope
The present document specifies technical characteristics and methods of measurements for the types of equipment:
1) Base Station for Evolved Universal Terrestrial Radio Access (E-UTRA).
2) Base Station for Evolved Universal Terrestrial Radio Access (E-UTRA) with NB-IoT.
3) Base Station for NB-IoT standalone.
NOTE: UTRA TDD is not included in Release 17 of ETSI EN 301 908.
This radio equipment type is capable of operating in all or any part of the operating bands given in table 1-1. Unless
stated otherwise, requirements specified for the TDD duplex mode apply for downlink and uplink operations in Frame
Structure Type 2. NB-IoT is designed to operate in the E-UTRA operating bands 1, 3, 8, 20, 28, 31, 41, 42, 43, 65, 72,
87, 88 which are defined in table 1-1.

NOTE 1: Restricted to E-UTRA DL operation when carrier aggregation is configured. The downlink operating
band is paired with the uplink operating band (external) of the carrier aggregation configuration that is
supporting the configured Pcell.
NOTE 2: Void.
NOTE 3: This band is an unlicensed band restricted to licensed-assisted operation using Frame Structure
Type 3. In Europe according to [i.10] and [i.11], radio equipment in band 46 operates between
5 150 MHz and 5 725 MHz as in table 1-2.
NOTE 4: In this version of the present document, restricted to E-UTRA DL operation when carrier aggregation is
configured. Band 46 is divided into three sub-bands as in table 1-2.
NOTE 5: In Europe according to [i.14] and [i.15], radio equipment in band 28 operates between 758 MHz to
791 MHz for the transmitter (FDL_low = 758 MHz and FDL_high = 791 MHz) and between 703 MHz to
736 MHz for the receiver (FUL_low = 703 MHz and FUL_high = 736 MHz).
NOTE 6: In Europe according to [i.27] and [i.28], radio equipment in band 41 operates between 2 570 MHz and
2 620 MHz (FDL_low = 2 570 MHz and FDL_high = 2 620 MHz).
NOTE 7: This band includes two frequency ranges that are harmonised in Europe:
(a) Based on [i.30], radio equipment in band 65 operates between 2 170 MHz to 2 200 MHz for the
transmitter (FDL_low = 2 170 MHz and FDL_high = 2 200 MHz) and between 1 980 MHz to 2 010 MHz
for the receiver (FUL_low = 1 980 MHz and FUL_high = 2 010 MHz) as the Complementary Ground
Component (CGC) of a Mobile-satellite service by reference to the present Harmonised
Standard.
(b) According to [i.24] and [i.28], radio equipment in band 65 operates between 2 110 MHz to
2 170 MHz for the transmitter (F = 2 110 MHz and F = 2 170 MHz), and between
DL_low DL_high
1 920 MHz to 1 980 MHz for the receiver (FUL_low = 1 920 MHz and FUL_high = 1 980 MHz).

Introduction
The present document is part of a set of standards developed by ETSI that are designed to fit in a modular structure to
cover radio equipment within the scope of the Radio Equipment Directive [i.1]. The present document is produced
following the guidance in ETSI EG 203 336 [i.3] as applicable.

ETSI

1 Scope
The present document specifies technical characteristics and methods of measurements for the types of equipment:
1) Base Station for Evolved Universal Terrestrial Radio Access (E-UTRA).
2) Base Station for Evolved Universal Terrestrial Radio Access (E-UTRA) with NB-IoT.
3) Base Station for NB-IoT standalone.
NOTE: UTRA TDD is not included in Release 17 of ETSI EN 301 908.
This radio equipment type is capable of operating in all or any part of the operating bands given in table 1-1. Unless
stated otherwise, requirements specified for the TDD duplex mode apply for downlink and uplink operations in Frame
Structure Type 2. NB-IoT is designed to operate in the E-UTRA operating bands 1, 3, 8, 20, 28, 31, 41, 42, 43, 65, 72,
87, 88 which are defined in table 1-1.
