Interdigital, IMEC and Peraso show first WiGig mmwave mesh backhaul

Collaboration integrates 60GHz phased array, WiGig baseband and software

Interdigital, a mobile technology r&d company, the research centre Imec, and SiGe WiGig chip developer Peraso Technologies have announced the integration of their technologies into the world's first WiGig-based millimeter wave mesh backhaul system.

The technology has been designed to enable easier deployments for small cell mobile backhaul resulting in lower cost solutions for high-speed data delivery in 4G and 5G networks.

The system developed by the Interdigital Labs team includes Imec's 60GHz PHARA4 radio and phased array antenna with fast electrical beam steering in azimuth and elevation, and Peraso's SiGe PRS4000 WiGig baseband chip, operating at multi-Gbps data rates. InterDigital's software provides self-configuration and data routing for  the multi-hop mesh backhaul. 

The architecture uses radio  and baseband components targeted for high volume consumer electronics rather than proprietary architectures found in existing millimeter  backhaul solutions. Multi-sector rapid beam steering enables many links  to be supported with the same equipment for added cost-reduction,  reliability, and simple network scaling with additional nodes. InterDigital calls the solution EdgeHaul, and aims to bring it to industry field trials in the second half of 2015.

 "Millimeter wave is the only spectrum with enough available bandwidth to  provide fibre-like data rates," said Doug Castor, principal engineer,  InterDigital Labs group. "Cost-effective backhaul is a huge challenge  for small cell deployments and our approach will enable network  operators to rapidly deploy denser networks to meet growing capacity  demands. We're also excited about the opportunities to bring this  platform to other markets such as residential broadband and 5G mmW access."

"Peraso has been a significant contributor in the standardisation of 60GHz technology for many years. Our solutions are designed with a  low-power and modular software MAC that enable customer value-add  features and differentiation across a wide-variety of WiGig  applications," said Ron Glibbery, CEO of Peraso.  "We are extremely  pleased with the continuing emergence of WiGig eco-system products and  solutions utilising our chips as critical components."

"Our phased-array radio module is the result of more than ten years of 60GHz R&D at Imec. Initially developed for consumer-oriented WiGig  markets, the technology is inherently cost-effective and scalable.  Moreover, it features fully-integrated fast electronic beam-steering for  easy installation, adjustment without human intervention, and  reconfigurable mesh networking. The record energy efficiency of over 65 percent  (16 antenna) finally means a lower number of antenna needed and a small,  low-cost form factor," said Charlotte Soens, program manager millimeter  wave technologies at imec.
