San Jose, CA – July 16, 2026 – Cohere Technologies, the innovator behind the award-winning Universal Spectrum Multiplier (USM) software for 4G and 5G networks and Pulsone™ Technology powered by the Zak-Orthogonal Time Frequency and Space (Zak-OTFS) waveform, today announced support for the E3 interface. This will enable distributed applications (dApps), such as Cohere’s USM, to integrate more effectively with existing and new base stations, delivering improved spectral efficiency and network capacity. The E3 interface is designed for tighter integration of dApps with RAN nodes such as the CU and DU and will fuel new and innovative AI-RAN applications and services.
“We are pleased to join industry leaders who are committed to open networks. The establishment of the E3 interface marks a significant advancement for Open RAN ecosystems,” said Ray Dolan, CEO and Chairman of Cohere Technologies. “This commitment is an important step toward realizing truly open and AI-driven wireless networks.”
By enabling E3 compatibility, RAN vendors and operators can more easily leverage Cohere’s Delay-Doppler domain insights and Zak-OTFS innovations. This will accelerate AI-RAN capabilities, improve spectral efficiency, drive new use cases in ISAC, and support robust connectivity for NTN and defense applications.
Key benefits of E3 interface support include:
- Real-time programmability: USM, operating as a dApp, can optimize scheduling, precoding, and channel estimation for ultra-low latency performance.
- Seamless ecosystem integration: Full compatibility with O-RAN frameworks, enabling coordination with xApps and rApps via established interfaces while extending capabilities into the user-plane domain.
- Broad applicability: Enhanced support for 5G and future 6G networks, Massive MIMO, Open RAN deployments, Pulsone-powered ISAC capabilities, and improved satellite direct-to-device (D2D) communication.
- Developer-friendly deployment: Simplified onboarding for innovative dApps focused on AI inference, sensing, and dynamic resource management.
Support for the E3 dApp interface is expected to be available in upcoming releases of the USM, ECHO, and Pulsone platforms. The recently awarded government contract for the “Multi-Waveform Radio Access Network for Integrated Sensing and Communications” may also provide an opportunity to integrate the E3 interface into the OCUDU architecture as early as 2027.
