Last week ANATEL published Act 2271 related to the technical requirements for the conformity assessment of radio-frequency signal boosters used in the Personal Mobile Service – SMP which will enter into force on August 16th, 2022 (180 days after its publication). The signal booster must operate in accordance with the national frequency plan of Brazil and must comply with the requirements defined by this act.
For instance, in regards to the output power, it mentions that the maximum transmission power of the internal signal booster on the uplink must meet the limit established in the channeling regulations and conditions of use for the radio frequency band used. So, if the regulation does not establish an emission limit on the uplink for the radio frequency band, the internal signal booster must not exceed the maximum conducted power of 30 dBm (1 W) and, of this same value, in EIRP.
The maximum conducted power measured at the output of the downlink must not exceed the value of 17 dBm (0.05 W) and, of this same value, in EIRP. Power spectral density is limited to 10 dBm/5 MHz EIRP.
The compliance of the technical items applicable to the internal signal booster must be proven through the measurement procedures recommended by the FCC standard KDB 935210 D04 – Provider Specific Booster Measurements Guidance v02 (see table 1 in the attached pdf).
