Innovation is a cornerstone of the Proef Group, and so, added value products with customer tailored specificities are being developed in this field such as: All-in-One Power Solution – Telecom Site, RDS - Rapid Deployment, Light Cabinet Solution.

All-in-One Power Solution - Telecom Site
A solution for energy management in telecommunications stations that combines different sources of energy (solar panels, batteries and electrical generators), thus ensuring continuous operation and reduced energy waste.

RDS - Rapid Deployment
A solution that enables a rapid implementation and reduced maintenance requirements, allowing operators to significantly reduce their OPEX - CAPEX. When combined with renewable sources of energy, it becomes operational in places that are not connected to power grids.

LCS - Light Cabinet Solution
Multifunctional cabinets with the ability to expand, with access from the side and thermal and acoustic insulation. This solution is ideal for small sized telecommunications stations in urban environments, where limited space is the main obstacle.

The possibility to be placed on the rooftop of buildings and the ease of installation/removal minimizes costs in terms of renting spaces.
