How to design connectivity solutions while ensuring medical data remains within the country?
Patient data generated by cross-border medical devices within China must be stored locally. Connectivity solutions should be designed around two principles: onshore deployment and layered data export, with self-audits covering location, channel, and export compliance.
Multinational medical device manufacturers face a critical constraint: patient and clinical data generated in China must be stored within the country. Since devices are global models and data cannot leave China, connectivity solutions must be designed specifically for this requirement—not as an add-on, but as a foundational design constraint.
1. Two Design Principles
Deployed locally: Storage and compute use domestic nodes; device access, firmware updates, and log backhaul are fully closed-loop within China.Roaming SIM cards exit abroad, creating an inherent conflict with data sovereignty requirements.Avoid medical scenarios.
Layered data export: Overseas headquarters access only to anonymized statistical insights; raw data remains domestic. Where actual cross-border transfer is required, follow the official data export assessment process and retain documentation for audit purposes.
II. Self-Check: Three Key Questions
Before submitting your proposal, self-check using these three questions:
Query the drop pointWhere is the data stored and processed? Are all nodes located within China?
Inquire about channel: Integration, upgrade, and log localization—ensure logs remain within China with no cross-border export.
Ask about leaving the countryDo you have data cross-border transfer requirements? Are the assessment materials complete?
Data sovereignty isn't a feature limitation—it's a design principle. Define it early, and you avoid costly rework.
