The New Official Document, issued by the Brazilian ANATEL, responds to a query from the Committee of Designated Certification Bodies regarding the continued certification of FDD equipment operating in the former L sub-band (1895–1900 MHz uplink and 1975–1980 MHz downlink).

Consequently, ANATEL has established that the certification of new FDD equipment operating in the aforementioned band is no longer permitted, nor is the maintenance of previous certifications, as there are currently no authorized operators in the L sub-band.

The Certification and Numbering Department concludes that it is not necessary to maintain the certification of FDD products in this band, thus closing the possibility of their continued existence in the Brazilian market.

WHOM DOES IT IMPACT?

The direct impact is on equipment manufacturers and suppliers, laboratories, and designated certification bodies (DCBs).

CONCLUSION:

The impact is significant because it does not affect operating services or current users, but it does have implications for manufacturers, suppliers, and certification bodies. The measure reflects a clear strategy to reorganize the spectrum in favor of TDD technology, definitively closing the door to the operation and certification of FDD systems in the former L subband, thereby limiting business opportunities in Brazil for certain players in the sector.
