Cohere Technologies is making strides toward commercializing its universal spectrum multiplier (USM) as it conducts a live pilot in Bell Canada’s network, CEO Ray Dolan disclosed in an interview with Mobile World Live. This pilot exemplifies the ongoing collaboration between Cohere, Bell Canada, and Vodafone, all of whom are investors in the technology, aimed at enhancing the spectral efficiency of their open RAN networks.
In 2024, Vodafone tested the USM across a greenfield network in Spain, achieving a notable 50 percent increase in spectral efficiency. The ongoing trial with Bell Canada is particularly significant as it tests the software on existing radio base stations for brownfield deployments, showcasing the adaptability of the USM in diverse network environments.
Dolan explained that the current pilot pairs USM with a third-party vendor to facilitate joint scheduling on Bell Canada’s live network, which is currently handling commercial traffic. “There’s a site where we have a server with our USM on it,” he stated. “It sits behind a large established vendor.” This setup positions Cohere’s technology to enhance performance in conjunction with existing systems.
By integrating the spatial capabilities of USM with the time-frequency elements of its partner, Cohere aims to extend the operational capacity of mobile vendors. Dolan emphasized the pilot’s importance, stating, “We’re demonstrating that whatever they see, we can improve upon by pairing our users spatially.” Although USM achieved a 50 percent improvement in a controlled environment, the CEO noted it is premature to predict the performance uplift in the current pilot.
The next few months are deemed crucial for Cohere as they refine their technology and aim for broader deployment. Dolan expressed optimism about the potential outcomes, saying, “The next month or two is going to be a great opportunity for us to scale and demonstrate what we do.” He anticipates that, based on the pilot results, Cohere could begin commercial deployments with additional investors within a year.
“First, we’ve got to deliver the performance in our existing system. I’m quite confident we will, but the pressure’s on. We’ve got the next month or so of work to do. We’ve got to deliver,” Dolan added. He envisions evolving from a single vendor landscape to a multi-vendor environment and expanding beyond a handful of operators to a global scale.
This pilot not only highlights Cohere’s technological advancements but also positions the company within a competitive landscape of telecom innovations. As the demand for efficient spectrum usage grows, the success of USM could play a pivotal role in shaping the future of mobile network infrastructures.
