About us

Keima is the HetNet design and optimization specialist.

We are the company behind Overture, a powerful design software that delivers a holistic approach to modern network design. Overture has supported many of the largest HetNet deployments in North America. In fact more than 85% of all small cells in the US have been deployed using Overture.

For more than a decade, Keima has collected global social media and other usage data so that our software can provide precise modelling of outdoor data usage across the planet.

We have designed our software to support clients from business planning through to deployment, with accurate data that leverage the potential and mitigate the risks of network expansion.

We believe that in this new era of 5G densification, the industry requires changes in mindset and more efficient approaches to network design and rollout that are scalable and low-cost. We believe that in this new era of 5G densification, the heavy lifting needs to be done not on the ground but in the planning.

We believe this new era of 5G densification needs Keima’s Overture.
