Marco Di Costanzo

Marco Di Costanzo is Chief Technology Officer at TIM Brasil. An engineer by training, he has spent more than three decades in telecommunications, holding network leadership positions across Brazil, Argentina and Chile before assuming the CTO role. His career has been closely tied to network planning, infrastructure development and the technical decisions that shape how connectivity reaches customers at scale.

Expanding Capacity without Losing Reliability

Telecommunications leaders face ongoing pressure to increase network capacity while keeping service quality high. Customer expectations are rising. Each technology upgrade needs to fit into the existing infrastructure without affecting performance.

Di Costanzo's role places him at the center of that challenge. As CTO, he oversees the planning, development, construction and activation of TIM Brasil's network infrastructure. The position requires balancing near-term network demands with investments that must support future traffic growth.

His career progression is an indication of long-term specialization in network engineering. As CTO from 2024, he was a Network Engineering Director and also took part in roles that entailed the management of the development of mobile networks. This makes his appointment even timelier, considering the technological challenges faced by telecommunications companies.

Turning Coverage into Everyday Connectivity

Coverage figures can be used to measure the network expansion process, but the harder part would be to guarantee performance consistency when it comes to connectivity.

Di Costanzo has publicly associated advanced connectivity with development in general terms. The remarks made by him in relation to the 5G deployment at TIM Brasil underline the necessity of moving beyond big cities to achieve better digital connectivity.

The challenge extends beyond deploying infrastructure. Telecommunications networks must accommodate changing traffic patterns, new digital services and rising data consumption. Technical leadership, therefore, involves determining where capacity should be added, how infrastructure should evolve and which technologies justify long-term investment.

Those decisions carry particular weight within TIM Brasil, one of the country's largest telecommunications providers. The scale of the network increases both the opportunity and the complexity attached to technology planning.

Preparing Infrastructure for the Next Cycle

Networks created by technology companies are seldom created based on current demands alone. The infrastructure choices being made today may very well define service offerings in the future.

Di Costanzo is involved in preparations for future needs when it comes to the infrastructure of TIM Brasil. In recent times, some of the more notable initiatives from the public sector related to his field of expertise include efforts to modernize the existing network and using intelligent antennas.

The public statements he made about these initiatives contain an important common element. Instead of treating improvements in network infrastructure as engineering problems, he presented them as preparations for future needs.

His experience across multiple Latin American markets appears to have reinforced that long-term view. Throughout his career, he has worked in environments where network investment decisions required balancing technological ambition with execution discipline.

The role of an executive in the telecommunications industry goes well beyond introducing the latest technological advancements. In fact, decisions regarding infrastructure must be made based on needs that will hold true far into the future. This is something Di Costanzo has been doing throughout his career, from network planner positions he held early on, all the way up until the position of helping create one of Brazil’s largest telecommunications networks.
