Pulsone
From Wikipedia, the free encyclopedia
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]
