Who is Cohere?
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).
