Phased array beamforming can be used to increase the range and field of view of backhaul, access points and home units. The use of Pharrowtech technology could be used to eliminate the cost of connecting individual premises by optical fibre, Pharrowtech claims.
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.”
Pharrowtech designs could also be suitable for wireless VR/AR and other wireless links.
