A Hypersonic, Multi-G World?
WHAT? Mobility Can Go Hypersonic?
Yes, OTFS Delay-Doppler channels are immune to doppler effects. OTFS communications exhibits outstanding performance while operating within the high velocities of Low Earth Orbit (LEO) satellite constellations. Other valuable characteristics of OTFS such as a higher SNR, better immunity to fading or interference, and MIMO beamforming are also vital for satellites to process weak signals from terrestrial devices. At last, OTFS is the waveform our industry has been seeking that can apply to almost any conceivable venue from ground to space.
WHAT? I can do things in O-RAN that I cannot do in RAN?
O-RAN affords, for the first time, the ability for innovators to inject innovation into RAN technology. Older monolithic RAN appliances are tightly controlled and very slow moving platforms. O-RAN virtualizes the majority of the RAN into software hosted in commercial off-the-shelf (COTS) servers and enables injection points for innovation called the RAN Intelligent Controller (RIC).
Cohere leverages O-RAN xApp capabilities:
- Cohere first showcased its advantages in Feb. 2020 at Deutsche Telekom’s Headquarters in Bonn (Germany), as part of a public O-RAN showcase.
- In June 2021, Vodafone announced the results of a 5G Open RAN lab trial leveraging a SW solution from Cohere Technologies in partnership with Intel, VMware and CapGemini Engineering.
- Cohere’s Universal Spectrum Multiplier platform is an xApp in a near-Real Time RIC within a telco cloud or O-RAN, without any changes to handsets, radios or antennas.
WHAT? I can have 4G, 5G AND OTFS?
Our Universal Spectrum Multiplier xApp that has demonstrated up to 2x gains in spectral capacity is based on the Delay-Doppler channel model. The same Delay-Doppler principles that enable the “spectrum multiplier effect” can schedule orthogonal beams from multiple DUs: 4G, 5G, and OTFS, in the same spectrum.
WHAT? Double your Network Performance?
Cohere’s Universal Spectrum Multiplier (USM) software platform improves the strength and efficiency of any generation (“any G”) mobile network. Cohere’s 3GPP standard-compliant USM platform for the Radio Access Network (RAN) and Telco Cloud delivers on the promise of 5G by extending a mobile network’s spectral efficiency by as much as 2x, meaning a 5G user experience can be quickly and easily provided to end-users on all networks.
Cohere Technologies is the innovator of software which improves spectrum and user experience with channel detection, estimation, prediction and precoding deployed within a standard-compliant 4G, 5G or open Cloud RAN.
Cohere Technologies is headquartered in San Jose, California and is backed by leading investors such as NEA (New Enterprise Associates), Lightspeed Venture Partners, Telstra Ventures, Koch Investments Group (KSP), VMware, Intel Capital and Juniper — among others.

What Do We Do?
Cohere’s software-based solution significantly improves spectrum and capacity for 4G and 5G.
The pioneering work in the Delay Doppler domain enables robust channel estimation and accurate channel prediction into the future. It alleviates handset feedback requirements by leveraging geometric reciprocity and reduces computation complexity through concise channel representation. All of these features combine to deliver significant spectrum multiplier effect for 4G and 5G networks in both FDD and TDD.
Cohere’s software-based solution offers significant MU-MIMO benefits with no changes to existing handsets, and can work with existing base stations. The Cohere solution works in all available spectrum. Moreover, it allows 4G and 5G co-existence via a vendor neutral approach to dynamic spectrum reuse.
Cohere Technologies Universal Spectrum Multiplier
The Delay Doppler channel representation is predictable into the future given that its geometric nature is slow changing. This allows disaggregation of functions which enables Cloud RAN. Cloud RAN creates the foundation for improving cell edge performance via intercell coordination (CoMP).
