Pulsone Technology, Powered by the Zak-OTFS Waveform, Resolves Challenges With Non-Terrestrial Networks And Works With 5G and Emerging 6G Networks
SAN JOSE, CA, OCTOBER 20, 2025 — Cohere Technologies, the innovator of Universal Spectrum Multiplier (USM) software for 4G and 5G networks, and Orthogonal Time Frequency and Space (OTFS) waveform, today announced that it is launching its new Pulsone™ Technology business to develop wireless solutions for Non-Terrestrial Networks (NTN) and 5G/6G Integrated Sensing and Communications (ISAC) networks. The company first started work on OTFS in 2011 and in recent years, the company evolved the waveform to make wireless work better in complex Delay-Doppler channel environments at high-speeds to enable situational and operational awareness.
“The wireless industry is at a critical juncture as 5G continues to evolve but new use cases demand performance and functions that are beyond the capabilities of a standard that’s based on a twenty-five-year-old technology,” said Ray Dolan, Chairman and CEO at Cohere Technologies.
Pulsone Technology, powered by Zak-OTFS, enables performance improvements that assure the success of high-speed, multi-satellite connectivity, wireless communications using higher band spectrum, AI-powered networks, and ISAC for critical defense capabilities. Pulsone operates natively in the radar sensing domain, providing a fundamentally new way of interacting with the wireless channel by carrying information in the Delay-Doppler domain. This leads to superior predictability and stability in dynamic environments.
Situational Awareness is a cornerstone benefit of 6G, merging radar-like sensing with communication to create a platform that delivers real-time awareness of the environment. The ISAC framework enables networks to detect and analyze high-speed objects and movements, the conditions in the surrounding environment — by mapping reflective energy. This has profound implications for:
- Defense: ISAC can enhance surveillance, drone swarm detection, and battlefield situational awareness by combining high-resolution sensing with secure communication.
- Enterprise Automation: Factories, warehouses, and smart cities can use ISAC for real-time monitoring of equipment, traffic, or pedestrian movements, enabling autonomous systems and predictive maintenance.
- Consumer Applications: From augmented reality (AR) to autonomous vehicles, ISAC can provide precise environmental data, enhancing user experiences and safety.
The first showcase of Pulsone is a demonstration of the industry’s first real-time Neural Receiver, in collaboration with Duke University and Virginia Tech, taking place at NVIDIA’s GTC government conference on October 27-29 in Washington D.C.
About Pulsone Technology powered by the Zak-OTFS waveform
Zak-OTFS Is a configurable waveform that is a generalization of all existing 3GPP waveforms. It supports 5G (CP-OFDM). It has the ability to evolve into a flexible “mother of waveforms” for 6G. Pulsone Technology allows mobile network operators (MNOs) to use existing 5G hardware initially and transition to enhanced 6G performance through parameter tuning, enabling Pulsone to work with 5G without immediate hardware upgrades – thus giving customers the flexibility for waveform evolution from 5G to 6G based on network and device readiness. Earlier this year Cohere introduced Zak-OTFS to the wireless standards bodies.
