GCF Certification

Global Conformance Validation for Mobile Devices & Wireless Technologies

GCF Certification ensures that mobile devices, modules, and wireless equipment comply with globally recognised interoperability and network performance standards. Our certification support framework covers end-to-end testing, documentation, and validation to ensure devices meet industry, operator, and regulatory requirements before entering the market.

We work across all major radio technologies—2G, 3G, 4G, 5G, LTE-Advanced, NB-IoT—and enable manufacturers to achieve fast, reliable, and fully compliant certification outcomes.
