Pozyx vs Sewio — when each UWB platform wins.
Two of the most-asked-about UWB vendors in the mid-market. Both deliver production-grade UWB. The differences that matter for procurement are integration architecture, anchor sync, ecosystem maturity and commercial structure.
At a glance.
Pozyx: Belgian UWB platform; developer-friendly architecture and integration SDK; widely used in research, sport analytics and mid-scale industrial; accuracy 10–30 cm production-grade.
Sewio: Czech UWB platform; production-line industrial focus with RTLS Studio for floor-plan modelling; widely used in automotive and manufacturing; accuracy 30 cm @ 95th percentile.
Neither vendor reseller-locks the install. Both publish RF design parameters openly enough to support independent audit. The decision is fit-to-use-case, not technology-quality.
Where Pozyx wins.
Developer-centric integration: clean Python SDK and REST API; rapid prototyping; preferred for organisations building custom location intelligence on top of position streams.
Research and sport analytics deployments where flexibility matters more than turnkey rollout.
Mid-scale industrial where in-house IT absorbs the integration work.
Where Sewio wins.
Production-line industrial deployments where turnkey RTLS Studio for design, anchor management and live visualisation is the requirement.
Large automotive WIP and process-flow deployments where platform maturity decides.
Procurement teams that want packaged solutions with vendor-led commissioning rather than SDK-led custom build.
What the comparison costs.
Both price anchors at €200–€300. Install at €1,000–€1,500 per anchor. Cost differentiator is platform tier — Pozyx is closer to "raw platform + SDK", Sewio is closer to "platform + visualisation + management".
Total programme cost is rarely decided by anchor price; it is decided by anchor count and install bill. Independent audit typically saves 30–50% on either platform vs the vendor reference design.

Frequently asked questions
Is Pozyx accuracy better than Sewio?
Comparable. Both hit 10–30 cm at 95th percentile in production environments with correct anchor design. Differences come from anchor density and commissioning rigour.
Can we mix Pozyx and Sewio in the same deployment?
Not on the same RF stack. Different anchor sync architectures. You can run them in different zones if zones do not need to be position-continuous.
Which is easier to integrate into MES / WMS / ERP?
Pozyx is more SDK-first and faster for custom integration if you have in-house engineering. Sewio is more turnkey and faster if you want vendor-led integration packages.
Which has the stronger reseller / integrator network?
Sewio has the more established channel in DACH automotive. Pozyx has a broader research and developer community globally. Both can be installed independently.
