Recently ANATEL published the Act 2921, defining the new technical requirements for Personal Mobile Service Radio Frequency Repeaters with 4G LTE and 5G NR technology, which is already in force in Brazil.
This new regulation defines the new testing standards for 4G and 5G technologies, as below:
1) LTE FDD tests will be carried out According to ETSI TS 136 143 V17.0.0 (2022-04):
a) 6. Output power
b) 7. Frequency Stability
c) 8. Out of band gain
d) 9.1.5.2. Operating band unwanted emissions
e) 9.2.5.2. Spurious emission
f) 13. Adjacent Channel Rejection Ratio (ACRR)
2) LTE TDD tests will be carried out According to ETSI TS 136 141 V15.4.0 (2018-10):
a) 6.2. Base station output power.
b) 6.4. Transmit ON/OFF power (TDD).
c) 6.5.1. Frequency error.
d) 6.6.1. Occupied bandwidth.
e) 6.6.2. Adjacent Channel Leakage power Ratio (ACLR).
f) 6.6.3. Operating band unwanted emissions.
g) 6.6.3.5.2. Test requirements for Wide Area BS (Category B) e seus subitens no que for aplicável.
h) 6.6.4.5.2. Transmitter spurious emissions.
3) 5G NR FR1 (Conducted tests) tests will be carried out According to ETSI TS 138.115-1 V17.0.0 (2023-01):
