The Flemish business subsidies agency Vlaio has agreed to support a trial of fixed-wireless internet access 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 commercialisation 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.
