Cohere Technologies, the innovator of spectrum multiplier software for Open Radio Access Networks (O-RAN) and 4G, 5G and emerging 6G mobile networks, has evolved its spectrum software functionalities to deliver up to 2X spectrum performance boost for both 4G and 5G networks simultaneously when spectrum is being shared using Cohere’s Universal Spectrum Multiplier (USM).
Today’s Dynamic Spectrum Sharing (DSS) approach penalizes 5G mobile performance to accommodate 4G devices. Cohere’s USM now enables mobile operators to share spectrum between 4G and 5G subscribers to double performance, and take full advantage of Multi-User, Massive MIMO and cloud economics.
Cohere enables a graceful transition from 4G to 5G by facilitating full performance spectrum sharing that will improve ROI and ease 4G to 5G migration. Cohere’s patented Delay Doppler channel detection method facilitates orthogonal beam management which leads to breakthrough MU-MIMO performance in both FDD and TDD spectrum, using the same time and frequency resources. The Delay Doppler channel engine is waveform independent, thus facilitating multiple dissimilar waveforms to operate in the same spectrum band. The outcome is improved performance and maximized value of all spectrum assets.
Universal Spectrum Multiplier software can be integrated by network equipment suppliers in the RAN or as an xApp in the Telco Cloud. Cohere has already demonstrated 2X performance improvement for 4G FDD and 5G TDD for leading mobile operators such as Vodafone along with VMware, Intel, and CapGemini.
Cohere’s Spectrum Multiplier xApp is proven on VMware’s industry-leading Radio Access Network Intelligent Controller (RIC) telco cloud platform and leverages Intel’s FlexRAN reference architecture.
Cohere will conduct customer field trials for 5G FDD and 4G + 5G USM in the first half of 2022. This year Cohere will also demonstrate a 6G system using the Orthogonal Time Frequency Space (OTFS) waveform and show 6G and 5G co-existence with OTFS and OFDM waveforms.
