How can Brazil maximize the 5G opportunity?

Q&A with José Gamarski, Independent Telecom Consultant.

What  you think that the particular challenges of deploying 5G in Brazil will be?

I think that the major challenges for deploying 5G networks will be about the same for Brazil and the rest of the world. There are some issues and challenges that are typical in every country, for example, spectrum availability, infrastructure availability (finding sites and the costs for rentals), availability of time and cost of user devices, backward compatibility with the legacy networks which is a must to guarantee ROI, adaptation of the regulatory environment for the new proposed 5G services, standardization bodies’ updates and procedures. These are far from all the challenges involved, but are in my opinion the major ones.

You worked on the radio networks deployment for the Olympic Games in Rio in 2016, so how different do you think the Olympic Games in the future will be, when 5G networks are fully operational, for example in 2020 or 2024?

For each new Olympic Games, national organizing committees are responsible for upgrading existing cellular infrastructures, both planing and deploying new sites and expanding the existing infrastructure to ensure the required coverage, capacity  and quality. As the new games arrive, networks must get better and better. For example, during Rio 2016, the mobile data traffic was 10 times higher than in London in 2012. I believe that the mobile traffic in Tokyo will be at least 10 times higher than in Rio. This is a default as mobile penetration keeps going up. Tokyo 2020 will experience vídeo 4K/8K transmission for mobiles, and we all know the amount of capacity required to transmit this kind of vídeo.  There is no other way to provide the required quality of service, so operators must pay attention to what the market desires.

How can communities around Brazil maximise the 5G opportunity?

One of the big opportunities for 5G is Fixed Wireless Access (FWA) which will be made available by 5G networks, providing the market with higher capacities and better coverage for communities in the country that are still not well served by  modern communications.  5G will be the tool permiting the convergence of fixed and mobile services, allowing the country to advance in its communications infrastructure. Another aspect to be considered is that the deployment of this new technology will support so many verticals, and will speed up the creation of many new jobs in different markets, which is very important for the country’s development.

What are you most looking forward to at 5G & LTE Latin America in Rio de Janeiro on April 24-26?

I believe that this will be the most focused event adressing the issues of 5G & LTE in Brazil during 2018. Since I have worked with the designs and deployments of various celullar generations in Brazil, I believe that I can share some understanding of challenges that professionals may face during 5G deployments.  I think that this technology deployment will allow creation of a new environment to develop the market as a whole and create new jobs.

José Gamarski will be speaking on Challenges to the Success of Deploying of 5G Networks at 5G & LTE Latin America on 26th April.
