The National Telecommunications Agency (ANATEL) of Brazil proposes technical requirements and test procedures applicable to the conformity assessment of the Radio Base Stations with Active Antenna System (AAS) technology.

The test procedures are found in the normative documents below, and must be carried out in accordance with the guidelines contained in Chapter 4 ( General Test Conditions and Declarations ) and Chapter 5 ( Applicability of Requirements ) of the normative document.

Technology Active Antenna System (AAS) Base Station (BS) - Conducted

Test Procedure

• ETSI TS 137 145-1 V15.2.0 (2019-04) - Universal Mobile Telecommunications System (UMTS); LTE; Active Antenna System (AAS) Base Station (BS) conformance testing; Part 1: Conducted conformance testing (3GPP TS 37.145-1 version 15.2.0 Release 15).

Test Items

• 6.2 Base station output power
• 6.4 Transmit ON / OFF power (TDD)
• 6.5.2 Frequency error
• 6.6.2 Occupied bandwidth
• 6.6.3 Adjacent channel leakage power ratio (ACLR)
• 6.6.5 Operating band unwanted emissions
• 6.6.6 Spurious emissions
• 6.7 Transmitter intermodulation
• 7.6 Receiver spurious emission

Technology Active Antenna System (AAS) Base Station (BS) - Radiated

Test Procedure

• ETSI TS 137 145-2 V15.2.0 (2019-04) - Universal Mobile Telecommunications System (UMTS); LTE; Active Antenna System (AAS) Base Station (BS) conformance testing; Part 2: Radiated conformance testing (3GPP TS 37.145-2 version 15.2.0 Release 15).

Test Items

• 6.2 Radiated transmit power
• 6.3 OTA Base station output power
• 6.5 OTA Transmit ON / OFF power
• 6.6.2 OTA Frequency error
• 6.7.2 OTA Occupied bandwidth
• 6.7.3 OTA Adjacent channel leakage power ratio
• 6.7.5 OTA Operating band unwanted emissions
• 6.7.6 OTA Spurious emission
• 6.8 OTA Transmitter intermodulation
• 7.7 OTA Receiver spurious emission

For the transmission power test, the maximum output power tolerance shall be ± 2,7 dB for carrier frequency f ≤ 3,0 GHz and ± 3,0 dB for carrier frequency f > 3,0 GHz.

The assessment shall be carried out under the conditions of temperature and relative humidity ranges defined in the Climate Cycle test defined in the Technical Requirements for the environmental conditions and tests applicable in the conformity assessment of products for telecommunications Act No. 14098 of November 23, 2017.

The proposed date of entry into force is 5/22/2019.
