Vlaio has agreed to support a trial of fixed-wireless internet access (FWA) in the 60 GHz band using semiconductor start-up Pharrowtech’s mmWave technology. Belgian cable operator Telenet and wireless equipment supplier Unitron are also participating, with the trial services expected to start for homes and businesses in 2022.

The trial will focus on validating the performance of Pharrowtech’s mmWave technology, to help the company move towards commercialization of its products. Pharrowtech said its CMOS process technology makes mmWave services in the 60 GHz band a cost-effective, high-performance alternative to fibre roll-outs. The technology is reliable and robust enough to cope with the outdoors environment, while delivering superior performance compared to alternatives in the market, in urbran or rural areas, the company said.

The Vlaio grant will be used to support preparation and execution of the Telenet field trial of Pharrowtech’s mmWave RFIC technology using Unitron’s network elements. Beamforming and mesh control software developed by labs at the Flemish research institute Imec will also be used in the trial.

Telenet, which is controlled by the Liberty Global group, said it has multiple use cases in mind where FWA could bring benefits such as reducing installation and roll-out costs. The operator last year started exploring a cooperation on FTTH roll-out in Flanders, but has yet to commit to a technology for its next network upgrade after Docsis 3.1. In the US, operators such as Mediacom and Alaska Communications are already exploring FWA services.

Pharrowtech was founded in 2018 as a spin-off from Imec, where the founding team led CMOS IP generation and prototype development in mmWave wireless systems for more than fifteen years. In 2019, the company secured more than EUR 6 million in seed funding from imec-Xpand, Bloc Ventures and the KBC Focus Fund, and in June this year the company released its first evaluation board.

Pharrowtech CEO and Co-Founder, Wim van Thillo, said: “We are extremely pleased that VLAIO is supporting us to roll out our technology with these leading partners. This field trial perfectly represents the massive business opportunity that mmWave FWA offers. Even in areas as densely populated as Belgium, operators struggle to deploy gigabit internet services fast enough. This project will establish our technology as a key complement to fiber for fast and economical high-speed internet deployments everywhere.”

Unitron CTO, Stephen Deleu, said: “With this VLAIO project, UnitronGroup will expand its knowledge in the higher frequency ranges and discover new wireless applications for ultrafast broadband communication. UnitronGroup is the market leader in multiple high frequency technologies, and collaborating with knowledge partners helps us strengthen our position. As a key technology partner for multiple telecom operators, our role in this ambitious project is to provide the FWA customer and distribution node elements. We are excited to be part of this consortium and looking forward to the insights and outcomes of this VLAIO project.”

Telenet, Director Network & Infrastructure, Luk Bruynseels, said: “For Telenet it is paramount to keep on investing in innovative ways to deliver digital services to our customers. We have multiple use cases in scope where FWA technology brings opportunities and important benefits by reducing installation and roll-out costs. This VLAIO project is a great opportunity for Telenet to gather and share all required knowledge and expertise within the consortium to ensure we meet the expected outcome of the project.”
