Engineers, not resellers.

ACTA was founded in Athens in 2002 to bring proper test & measurement practice to the networks rolling out across South-East Europe. Two decades later, that's still the job.

— Who we are

A specialist house with a generalist's curiosity.

Founded in October 2002 in Athens, ACTA Ltd is a Test & Measurement provider focused on Telecoms, IT, Electronics, and EMF/EMC technology. We serve operators, integrators, universities, public bodies and service centers across Greece, Cyprus, Albania and North Macedonia.

Our team is small, deliberately. Every engineer here has spent time in the rack, on the tower, or alongside a research consortium — which is why we don't sell instruments we wouldn't trust ourselves. We carry calibrated kit from world-leading manufacturers, configure it to the job, and stay on the line after delivery.

That same posture is why we co-author research with European Commission–funded programmes. Bringing measurement rigor to consortium-scale work is how we keep our edges sharp — and how the next generation of instruments lands in the field properly tested.

— Milestones

Two decades of measurement.

A short, honest version. We've left out the trade shows.

2002
ACTA Ltd founded
Established in Athens to bring test & measurement specialization to the SE European telecom market.
2006
EMF safety practice
First broadband and selective-probe deployments with public-body customers — early non-ionizing radiation surveys.
2011
Regional expansion
Sustained support presence in Cyprus, Albania and North Macedonia. First multi-country FTTH rollout support.
2016
First H2020 consortium
Joined an EU-funded research programme as the measurement partner — beginning of our R&D track.
2021
5G commissioning at scale
Commissioning kits and KPI workflows for 5G rollouts at OTE-class operators across the region.
2024
6G-PATH kickoff
Joined a 36-month Horizon Europe / SNS-JU programme on 6G path-aware experimentation.
2026
Wideband 0–90 GHz EMF
First field deployments of a new generation of digital-probe wideband meters, with city-authority partners.
