Case Study: NTT DOCOMO achieves faster, lower-cost O-RAN validation with Spirent Communications

Spirent O-RAN solutions with industry-leading 5G Core emulation make multi-vendor network validation faster, easier, and less expensive

NTT DOCOMO, Japan’s largest telecommunications company, faced the challenge of validating multi-vendor Open RAN (O-RAN) systems for its global operator customers. They needed to quickly and cost-effectively demonstrate that these open solutions could deliver carrier-grade performance, requiring comprehensive testing capabilities for proof-of-concept demonstrations without building expensive, full-scale infrastructures for each test. Spirent Communications provided the testing solution to address this.

Spirent implemented its O-RAN solutions, featuring industry-leading 5G Core network emulation. This allowed NTT DOCOMO to rapidly configure tests, generate real-world traffic conditions, and conduct comprehensive validation of performance and security. The results included increased customer trust, global reach to address diverse carrier requirements, and lower costs with a faster time to market due to built-in automation in the Spirent solution.
