The Wi-Fi Networks solution includes the design, sizing, and deployment of wireless connectivity infrastructure for corporate environments, industrial facilities, and critical infrastructures.

The architecture is structured to ensure adequate coverage, predictable performance, interference control, access security, and scalability, considering user density, traffic profile, and operational criticality.

A3A Engenharia de Sistemas develops each solution based on technical radiofrequency studies, coverage modeling, spectrum analysis, and definition of segmentation and security policies, ensuring full integration with the logical network and existing physical infrastructure.
