The Radio Link solution covers the design, sizing and deployment of point-to-point or point-to-multipoint communication systems based on radio-frequency technology, intended to interconnect remote units, buildings, industrial plants and critical infrastructures.

It is a technical alternative for medium- and long-distance links, especially in contexts where the deployment of cabled physical infrastructure is unfeasible, economically restrictive or operationally complex.

A3A Engenharia de Sistemas structures each solution based on technical feasibility studies, topographic profile analysis, line-of-sight calculations, Fresnel zone evaluation, attenuation modeling and expected availability targets, ensuring predictable performance and operational reliability.
