en.Wedoany.com Reported - TIM has begun deploying new telecommunications infrastructure in the historic site of Olinda, Brazil, to expand 4G and 5G network coverage and capacity in this UNESCO World Heritage area. The project plans to install three new transmission sites at strategic locations in Cidade Alta, including Alto da Sé, Quatro Cantos, and Varadouro.

Due to the UNESCO designation and federal legal protections for Olinda's historic site, conventional tower installations are restricted. To address this, TIM will use camouflaged antennas integrated into building facades to enhance network capacity without compromising the protected urban landscape. The deployment was carried out with permits from the Olinda City Hall, the Municipal Heritage Secretariat, the National Institute of Historic and Artistic Heritage (Iphan), and the Heritage Preservation Council, with coordination among stakeholders beginning in November 2025.

The 3.5GHz frequency band used by the 5G network offers higher transmission capacity but has a smaller coverage range compared to previous generations, posing challenges in protected areas. According to TIM, the adopted solution combines small antennas integrated into local buildings with a transmission network based on high-capacity fiber optics. The new transmission points carry traffic generated by the antennas via fiber backhaul.

Gustavo Maciel, TIM's Network Operations Manager for the Northeast region, stated that this modernization will significantly expand available capacity in the historic center. The new infrastructure is expected to increase the current mobile network capacity in the service area by up to ten times, with physical equipment installation handled by IHS Brasil. The new transmission points can also be used by other operators to reduce the need for additional installations within the historic area, aligning with the telecom industry's trend of infrastructure sharing.

In addition to serving daily residents, businesses, and tourists, the project is designed for periods of high user concentration, particularly during Olinda's Carnival. TIM expects that during the 2027 Carnival, traffic generated by the 5G network will exceed 50% of total mobile data volume in the region for the first time. Bruno Talento, TIM's Sales Director for the Northeast region, stated that the goal is to combine network capacity with historic heritage preservation, providing a robust and nearly invisible network.
