Cohere Technologies

Cohere Technologies is a telecoms software company based in San Jose, California that develops technology for boosting the network performance of 4G and 5G spectrum in wireless networks. Cohere holds the patents for the Orthogonal Time Frequency Space (OTFS) 2D modulation technique used to improve the performance of 4G and 5G networks and is being considered as a waveform for the future 6G wireless standard.

History
Cohere Technologies was founded in 2011 by Shlomo Rakib, a serial entrepreneur, and Ronny Hadani, an associate professor of mathematics at the University of Texas, Austin. The pair patented the OTFS waveform in 2010.

Ray Dolan, co-founder of Flarion Technologies (acquired by Qualcomm in 2006), joined Cohere Technologies as the company's chairman and CEO in October 2018.

Cohere Technologies' first trials of OFTS with a carrier took place at Telefónica in 2018.

In 2018, the company changed its focus to the use of Delay-Doppler-based channel detection, estimation and prediction, as well as precoding software to improve 4G and 5G wireless systems with its Universal Spectrum Multiplier software.

In 2020, Cohere Technologies won a GSMA GLOMO award for "Best Network Software Breakthrough,"  and was also shortlisted for the award in 2023.

In February 2023, Cohere announced a collaboration with telecommunications company Mavenir. Cohere will assist Mavenir in its transition to open RAN technology, including OTFS.

Cohere co-announced the Multi-G O-RAN initiative in April 2023 in collaboration with Intel, Juniper Networks, Mavenir and VMware. The initiative will provide frameworks and interfaces to support the coexistence of 4G, 5G, and other waveforms in the future. Carriers supporting the initiative include Vodafone, Telstra, and Bell Canada.

Cohere currently holds more than 300 patents relating to 4G, 5G, and OTFS.

Co-founder Shlomo Rakib currently serves as Cohere's CTO.

Products
Announced in 2021, Cohere's Universal Spectrum Multiplier (USM) software is designed to boost the performance of  4G and 5G FDD or TDD networks and can be integrated by network equipment suppliers in the radio access network (RAN) or as an xApp/RIC in the telco cloud. This technology has been tested by mobile operators such as Vodafone, Deutsche Telekom, and Telstra.

Cohere also announced the Dynamic Network Alignment (DNA) tool  in 2023, which is an automated MU-MIMO beamforming solution for calibrating 4G and 5G networks using existing network and spectrum assets.
