GREENSPHERE UNIPESSOAL LDA

Their core work

GreenSphere is a Portuguese technology SME specializing in wireless network design, self-organizing radio systems, and 5G/beyond-5G communications. They develop solutions for autonomous network management, heterogeneous network optimization, and IoT connectivity — applying these capabilities to domains ranging from underwater robotics to aerial-terrestrial networks. Their work bridges the gap between academic wireless research and practical deployment, with particular strength in simulation modelling and software-defined radio (SDR) prototyping.

What they specialise in

How they've shifted over time

GreenSphere started in 2015 with underwater robotics communication (SWARMs) and LTE-era self-organizing radio networks (SONNET), focusing on context-aware, coordinated multipoint transmission. From 2018 onward, their work shifted decisively toward 5G/B5G heterogeneous networks, distributed AI, and aerial IoT — reflecting the broader industry move from LTE optimization to intelligent, multi-domain 5G infrastructure. Their most recent projects show growing interest in AI-driven network management and trustworthy cross-domain systems.

GreenSphere is moving toward AI-driven, multi-domain wireless systems — expect future work combining autonomous networks with trustworthy AI for aerial, terrestrial, and IoT applications.

How they like to work

GreenSphere balances leading and contributing: they coordinated 2 of their 5 projects (both MSCA-RISE staff exchange programmes), while participating as a partner in larger RIA consortia. With 89 unique partners across 19 countries, they maintain a broad European network rather than relying on a small circle of repeat collaborators. This makes them an accessible partner — experienced in both running international research exchanges and contributing specialist wireless expertise to large consortia.

GreenSphere has built a remarkably wide network for an SME: 89 unique partners across 19 countries from just 5 projects. This breadth is partly driven by their MSCA-RISE coordination, which involves large international staff exchange networks spanning academia and industry.

What sets them apart

GreenSphere stands out as a small Portuguese company from Águeda that punches well above its weight in wireless communications research, coordinating international MSCA networks while also contributing to major RIA projects. Their rare combination of deep 5G radio expertise with applied experience in robotics (underwater, aerial) and distributed AI makes them a versatile partner for projects needing wireless connectivity in unconventional environments. For a company of their size, their 19-country partner network is exceptionally broad.
