Pulsone Technology is a wireless communications technology and business unit developed by Cohere Technologies for Integrated Sensing and Communications (ISAC) networks and Non-Terrestrial Networks (NTN).[1][2] Launched in October 2025, Pulsone is based on the Zak-OTFS (Zak-Orthogonal Time Frequency Space) waveform, which operates in the delay-Doppler domain rather than the traditional time-frequency domain used by OFDM (Orthogonal Frequency Division Multiplexing).[1][2][3]
The technology is designed to address challenges in high-mobility communications, satellite links, and radar applications.[1][3]Unlike OFDM-based systems that struggle with Doppler shifts and delay spread in Non-Terrestrial Networks, Pulsone Technology leverages the inherent stability of the Delay-Doppler domain for improved performance in dynamic environments.[1][3]The name combines “pulse” (radar sensing) and “tone” (communications), reflecting the technology’s dual-use capability for ISAC applications.[3]
Pulsone is positioned for 5G enhancement, 6G networks, defense applications, and satellite communications.[1][2][4] The technology has attracted interest from defense sectors for applications including drone swarm detection, missile defense systems, and secure military communications.[1][4][5]
History
Cohere Technologies began development of OTFS technology in 2011, with the Pulsone Technology brand trademarked several years prior to its commercial launch.[3]The company announced Pulsone as a distinct business unit on October 20, 2025, focusing on ISAC and NTN applications separate from its existing Universal Spectrum Multiplier (USM) product line for 4G/5G networks.[1][3][4][2][6]
The first public demonstration occurred at NVIDIA‘s GTC government conference in Washington D.C. from October 27-29, 2025, featuring a real-time neural receiver running on NVIDIA’s Jetson platform.[1][4][6][2]This demonstration was conducted in collaboration with researchers from Duke University and Virginia Tech.[1][4][2]In January 2026, Cohere announced accelerated development efforts for NTN applications and expanded academic partnerships including the 6G@UT Research Center at the University of Texas at Austin.[7]
