5G interference filters to be installed in seven years | Telecommunications

The auction of 5G should occur in 2021, and the 3.5 GHz frequency can cause interference in the service of open satellite TV (TVRO), which uses C band. The distribution of LNBF filters for satellite dishes could solve the problem, but the replacement of equipment throughout Brazil may take seven years.

The schedule was provided by Conexis (formerly SindiTelebrasil), which represents the main telecommunications operators. The entity estimates that it will be necessary to implement the filter in equipment of 1.37 million people who are in the Federal Government’s CadÚnico and live in regions where interference would be caused.

This is the timetable for 5G interference solution proposed by Conexis:

Period Cities
12 months Belo Horizonte, Brasília, Cuiabá, Curitiba, Manaus, Natal, Porto Alegre, Recife, Rio de Janeiro, Salvador, and São Paulo
24 months Rest of capitals and cities with more than 500 thousand inhabitants
36 months Cities with more than 200 thousand inhabitants
48 months Cities with more than 100 thousand inhabitants
60 months Cities between 30 and 100 thousand inhabitants and the rest of PGMC 1 (competitive municipalities)
72 months Rest of cities with PGMC 2 (potentially competitive municipalities)
84 months Rest of cities with PGMC 3 (municipalities not very competitive)

Migration to Banda Ku would cost R $ 1.75 billion

If the mitigation solution with LNBF filter is not accepted by Anatel, the effort will be even greater: the disconnection of the TVRO service in Band C and transfer to the Ku band would imply decoders, antennas and filters in all 5,570 Brazilian municipalities, with much higher cost for operators.

In the interference mitigation plan, Conexis expects operators to spend R $ 224.13 million on the distribution and installation of filters. The migration from band C to band Ku would be 7.8 times more expensive, reaching R $ 1.75 billion – this considering the dollar quotation at R $ 4.18 and equipment only for CadÚnico users.
