As it attended TMN’s Mobile Network Innovation Summit in London, Cohere Technologies announced ECHO, a new feature for its Universal Spectrum Multiplier (USM) software.
The company said that ECHO, which stands for Enhanced Channel Insight with Holographic Observability, “leverages USM to generate unprecedented real-time wireless channel insights,” enabling operators to see, understand, and act on the physical radio environment with “unprecedented precision”.
Cohere added that because of these capabilities, ECHO can enable Integrated Sensing and Communications (ISAC) for consumers and national defense, Digital Twin Networks, and improved network resilience and performance.
“For the first time, mobile operators can map the physical reality of antennas, connectors, radios, and other equipment on the tower to the actual radio channel. This enables tracking of system drift caused by aging hardware and environmental changes, pinpointing Delay-Doppler origins, and building accurate geometric models of channel state information for every user (UE),” said Ray Dolan, Chairman and CEO of Cohere Technologies.
“By logging 200 distinct attributes every second and generating more than 400 million lines of telemetry per day/sector, Cohere’s ECHO solution reveals the rich, continuous data needed to optimise network performance and predict issues before they occur.”
According to Cohere, conventional systems see only a fraction of this data, whereas USM with ECHO maps the entire channel, thus enabling AI to turn what appear to be random channel characteristics into the building blocks of a deterministic wireless connection.
Data for AI RAN
Dolan continued: “At scale, ECHO delivers the data to realise AI RAN today. By revealing the geometry of the wireless reflective environment, ECHO forms the basis for digital twins for enterprise and public safety. It also unlocks entirely new use cases such as ISAC (Integrated Sensing and Communications). Sensing is the overwhelming objective driving 6G development and Cohere is at the forefront of sensing with the combination of our USM solution and our OTFS waveform.”
ECHO’s network insights are achieved through a high-resolution view of channel dynamics, including:
• Latency, motion vectors, amplitude, and visibility for every device in the sector
• MU Gain Estimate: Multi-user gain above the single-user baseline
• Angle of Arrival Distribution: Precise traffic direction from each device
• Phase and Gain Adjustments: Continuous calibration of the transmission chain by USM, via Cohere’s DNA technology for USM, to maintain optimal performance
• Spectral Efficiency: Bits per second per Hz, calculated in real time
• MU-MIMO Percentage of FDD traffic scheduled as multi-user MIMO.
Cohere said the ECHO feature was used in recent field trial and production networks as part of testing the Universal Spectrum Multiplier software, to present how the USM software was working in joint schedule coordination with an existing third-party base station.
A statement from Cohere said:
ECHO’s insights enable AI-enabled layered inference, in which massive site-level telemetry streams are distilled into compact, high-value insights and actions that flow efficiently between network layers. AI training engines gain continuous knowledge of network changes, allowing dynamic optimisation of scheduling, beam management, and coordination across multiple base stations in borderless cell environments. Digital-twin models become dramatically more accurate and responsive because they are fed rich real-time data from the physical channel rather than sparse and aggregated statistics. ECHO enriches ISAC bi-/multi-static sensing on today’s 5G base stations.
“Operators and partners can monetise this unique radio-environment dataset to fuel next-generation operations, automation, and value-added services,” said Robert Curran, Consulting Analyst with Appledore Research. “Cohere’s USM with ECHO feature may have a transformative impact on AI-RAN, ISAC, and Digital Twin Networks.”
