Cohere Technologies

Cohere Technologies is a privately held telecommunications software company headquartered in San Jose, California. Its business focuses on improving the performance, capacity, and observability of mobile wireless networks, particularly 4G and 5G radio-access networks. The company’s technology work is associated with Orthogonal Time Frequency Space (OTFS), a two-dimensional wireless waveform and channel-representation approach intended to provide more stable communications under difficult mobility, Doppler, and multipath conditions. The company was founded in 2011 by serial entrepreneur Shlomo Rakib and mathematician Ronny Hadani, an associate professor at the University of Texas at Austin. Rakib and Hadani had patented the OTFS waveform in 2010, and Cohere initially concentrated on commercializing that research for mobile-network applications. Rather than positioning itself primarily as a conventional radio-equipment vendor, Cohere developed software intended to work with existing network infrastructure, base-station systems, cloud platforms, and open radio-access-network architectures. A significant change in the company’s commercial direction occurred in 2018. Cohere began emphasizing delay-Doppler channel detection, estimation, prediction, and precoding software as tools for improving deployed 4G and 5G systems. That year also brought the company’s first reported carrier trials, conducted with Telefónica. Raymond Dolan, a co-founder of Flarion Technologies and former executive associated with the development of advanced mobile-network technology, joined Cohere as chairman and chief executive officer in October 2018. Cohere’s principal commercial platform is the Universal Spectrum Multiplier, or USM. Announced in 2021, USM is designed to increase spectral efficiency and improve multi-user multiple-input, multiple-output performance in both frequency-division duplex and time-division duplex networks. It can be integrated into radio-access-network equipment or deployed as an application in a near-real-time RAN intelligent controller and telco-cloud environment. The platform uses cloud-based architecture, delay-Doppler channel modeling, machine-learning-assisted scheduling, and beamforming to coordinate network resources across sites. The company has reported testing or demonstrations involving operators and technology partners including Vodafone, Deutsche Telekom, and Telstra. Cohere has expanded its product portfolio beyond the core USM platform. Dynamic Network Alignment, announced in 2023, is an automated MU-MIMO beamforming and calibration tool intended to use existing network and spectrum assets. In 2025, the company introduced Pulsone Technology, a product family based on the Zak-OTFS waveform and aimed at integrated sensing and communications, non-terrestrial networks, satellite communications, and future 6G systems. In 2026, it announced ECHO, or Enhanced Channel Insight with Holographic Observability, a feature designed to transform operational USM data into detailed, real-time information about wireless channels and radio environments. Potential applications include sensing, digital-twin networks, network resilience, and AI-supported radio optimization. The company has participated in the development of open and disaggregated mobile-network ecosystems. In February 2023, it announced cooperation with Mavenir in support of Open RAN. In April 2023, Cohere joined Intel, Juniper Networks, Mavenir, and VMware in announcing the Multi-G O-RAN initiative, with support from operators including Vodafone, Telstra, and Bell Canada. In March 2026, it joined the OCUDU Ecosystem Foundation, a Linux Foundation initiative focused on an open, multivendor, software-driven ecosystem for AI-RAN innovation. Cohere reports holding more than 300 patents related to 4G, 5G, and OTFS technologies. Its current positioning combines wireless intellectual property with deployable software for network operators and equipment suppliers. The co…

Cohere Technologies emerged from research into Orthogonal Time Frequency Space, or OTFS, a wireless waveform and channel-representation technique developed by mathematician Ronny Hadani and entrepreneur Shlomo Rakib. The pair patented the technique in 2010 and founded Cohere Technologies in 2011. OTFS represents wireless channels in the delay-Doppler domain, allowing systems to model signal delay and frequency shifts more explicitly than conventional time-frequency approaches. The company’s initial objective was to translate that research into practical improvements for mobile communications operating under mobility, multipath, and rapidly changing channel conditions. During its early period, Cohere concentrated on the commercialization of OTFS for 4G and 5G networks. The company’s first reported carrier trials took place with Telefónica in 2018. That year marked a broader strategic emphasis on delay-Doppler channel detection, estimation, prediction, and precoding software rather than on waveform research alone. Raymond Dolan, a co-founder of Flarion Technologies, joined as chairman and chief executive officer in October 2018, bringing experience from the development and commercialization of advanced wireless-network technologies. Cohere subsequently developed software intended to work with existing radio-access-network infrastructure. Its main platform, the Universal Spectrum Multiplier, was announced in 2021. USM is designed to improve spectral efficiency and multi-user MIMO performance in both FDD and TDD networks. It can be integrated into network-equipment supplier products or deployed as a RAN-intelligent-controller application in a telco-cloud environment. Its architecture combines cloud-based processing, multi-site visibility, delay-Doppler channel modeling, machine-learning-assisted scheduling, and beamforming. The approach is intended to allow operators to increase capacity using existing spectrum and network assets rather than relying solely on additional spectrum or major hardware replacement. The company broadened its product scope in 2023 with Dynamic Network Alignment, an automated MU-MIMO beamforming and calibration tool. It also increased its participation in the Open RAN ecosystem. In February 2023, Cohere announced a collaboration with Mavenir, and in April it joined Intel, Juniper Networks, Mavenir, and VMware in the Multi-G O-RAN initiative. Operators identified as supporting the initiative included Vodafone, Telstra, and Bell Canada. These activities reflected Cohere’s preference for software that can operate across disaggregated network environments and interact with equipment from multiple vendors. Field activity provided further demonstrations of the USM approach. Vodafone and Cohere reported completing a field test in February 2024 in Vodafone’s 5G network in Ciudad Real, Spain, following earlier laboratory demonstrations. In February 2025, Cohere and Bell Canada reported a brownfield field test conducted during December 2024 and January 2025 near Bell’s technology laboratories in Mississauga, Ontario. The test used Bell’s 850 MHz FDD spectrum on a 5G standalone network. Cohere described USM as operating on a server alongside the gNodeB and coordinating scheduling with a third-party base station to improve MU-MIMO capacity. In October 2025, Cohere launched Pulsone Technology as a distinct family for integrated sensing and communications, non-terrestrial networks, satellite communications, and 6G research. Pulsone is based on the Zak-OTFS waveform and uses delay-Doppler processing rather than the conventional time-frequency orientation associated with OFDM systems. The family also includes a real-time neural receiver developed with academic collaborators and demonstrated on an NVIDIA Jetson platform at a government-focused GTC event. In 2026, Cohere announced ECHO, or Enhanced Channel Insight with Holographic Observability. ECHO is designed to capture operational data from USM and make it available for real-time channel analysis and wireless functions. The company presents the feature as a foundation for integrated sensing, digital-twin networks, AI-assisted inference, adaptive scheduling, beam management, and improved resilience. In March 2026, Cohere also joined the OCUDU Ecosystem Foundation, a Linux Foundation initiative focused on an open, multivendor software ecosystem for AI-RAN. Cohere has stated that it holds more than 300 patents related to 4G, 5G, and OTFS.
