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. [1] [2] 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. [5] [6] The pair patented the OTFS waveform in 2010. [7]

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. [8]

Cohere Technologies’ first trials of OFTS with a carrier took place at Telefónica in 2018. [9]

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. [10]

In 2020, Cohere Technologies won a GSMA GLOMO award for "Best Network Software Breakthrough,” [11] [12] [13] and was also shortlisted for the award in 2023. [14]

In February 2023, Cohere announced a collaboration with telecommunications company Mavenir. Cohere will assist Mavenir in its transition to open RAN technology, including OTFS. [15]

Cohere co-announced the Multi-G O-RAN initiative in April 2023 in collaboration with Intel, Juniper Networks, Mavenir and VMware. [16] [17] The initiative will provide frameworks and interfaces to support the coexistence of 4G, 5G, and other waveforms in the future. [16] Carriers supporting the initiative include Vodafone, Telstra, and Bell Canada. [16]

Cohere currently holds more than 300 patents relating to 4G, 5G, and OTFS. [18]

Co-founder Shlomo Rakib currently serves as Cohere's CTO. [19]

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. [20] [21] [22] This technology has been tested by mobile operators such as Vodafone, [23] Deutsche Telekom, [24] and Telstra. [25]

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. [26] [27]

<span class="mw-page-title-main">3G</span> Third generation of wireless mobile telecommunications technology

3G is the third generation of wireless mobile telecommunications technology. It is the upgrade over 2G, 2.5G, GPRS and 2.75G Enhanced Data Rates for GSM Evolution networks, offering faster data transfer, and better voice quality. This network was superseded by 4G, and later on by 5G. This network is based on a set of standards used for mobile devices and mobile telecommunications use services and networks that comply with the International Mobile Telecommunications-2000 (IMT-2000) specifications by the International Telecommunication Union. 3G finds application in wireless voice telephony, mobile Internet access, fixed wireless Internet access, video calls and mobile TV.

3G mobile telephony was relatively slow to be adopted globally. In some instances, 3G networks do not use the same radio frequencies as 2G so mobile operators must build entirely new networks and license entirely new frequencies, especially so to achieve high data transmission rates. Other delays were due to the expenses of upgrading transmission hardware, especially for UMTS, whose deployment required the replacement of most broadcast towers. Due to these issues and difficulties with deployment, many carriers delayed acquisition of these updated capabilities.

It was first used for fixed wireless, and is now a contending waveform for 6G technology due to its robustness in high-speed vehicular scenarios.

Delay Doppler coordinates are coordinates typically used in a radar technology-inspired approach to measurement. When used in wireless communication, the Delay Doppler domain mirrors the geometry of the reflectors comprising the wireless channel, which changes far more slowly than the phase changes experienced in the rapidly varying time-frequency domain.
