LEUVEN (Belgium), OCTOBER 16, 2018 — Pharrowtech, a spin-off initiative from the world-leading research and innovation hub imec, announces that it will demonstrate a prototype of a 60 GHz active phased array at the Telecom Infra Project Summit in London (October 16-17, 2018). Pharrowtech’s solution paves the way for telecom OEMs to dramatically increase range and field of view of backhaul nodes, access points and home units. It is fully built using low-cost, high-volume chip and antenna technology. This marks an important step towards accelerated deployment of cost-effective high-speed internet in rural, urban and suburban environments.

Fiber-to-the-home roll-out has proven prohibitively costly and slow. Wireless high-speed connections, known as fixed wireless access and enabled by the Pharrowtech technology, can ensure fast and reliable deployment in a broad range of scenarios where fiber-to-the-home is not feasible. It eliminates the extremely high CAPEX of connecting individual premises by fiber. Leveraging the unlicensed 60 GHz band further reduces OPEX, resulting in a highly favorable total cost of ownership for telecom operators.

Wim Van Thillo, program director at imec and Pharrowtech co-founder, said: “At imec, we have been pioneering low-cost mm-wave systems since 2005. Today, our modular design offers operators full flexibility to deploy in different neighborhood types having diverse building and vegetation densities while still meeting all regulatory requirements. Our prototype’s long range and large field of view are achieved through 256 antenna elements driven by 128 power amplifiers. Its proprietary chips are fully realized in high-volume CMOS technology to ensure low cost and power consumption.”
