Rohde & Schwarz, a global leader in test and measurement solutions for wireless communications, has announced that MediaTek is leveraging the Rohde & Schwarz CMP180 radio communication tester to test and verify TC-DFT-s-OFDM, a proposed waveform technology for 6G networks. The collaboration underscores the critical role of advanced testing equipment in developing foundational technologies that will power next-generation wireless communications.
TC-DFT-s-OFDM (Trellis Coded Discrete Fourier Transform spread Orthogonal Frequency Division Multiplexing) is being proposed to 3GPP as a candidate technology for 6G standardization. MediaTek’s research indicates that TC-DFT-s-OFDM provides superior Maximum Coupling Loss (MCL) performance across multiple modulation orders, including advanced formats like 16QAM.
According to MediaTek, the proposed 6G waveform offers enhanced cell coverage through reduced power back-off requirements and improved power efficiency via optimized power amplifier operation techniques, such as Average Power Tracking (APT). TC-DFT-s-OFDM enables up to 4dB higher transmission power compared to traditional modulation schemes while maintaining lower interference levels—representing up to a 50% increase in coverage area.
“MediaTek’s selection of our CMP180 for their 6G waveform verification work demonstrates the instrument’s capability to support cutting-edge research and development,” said Fernando Schmitt, Product Manager at Rohde & Schwarz. “As the industry advances toward 6G, we remain committed to delivering test solutions that empower our customers to push the boundaries of wireless innovation.”
The collaboration will be showcased at the Brooklyn 6G Summit, taking place from November 5–7, where industry leaders will discuss ongoing progress in defining the technical specifications for future wireless communications. As TC-DFT-s-OFDM moves through the 3GPP standardization process, precise testing with advanced tools like the CMP180 will play an essential role in validating performance and accelerating development.
The CMP180 radio communication tester is part of the comprehensive test and measurement portfolio from Rohde & Schwarz, designed to support wireless technology development from early research through commercial deployment.
