Liberty Global, Ericsson enable DAA, FTTH over wireless backhaul DetailsJoseph O'Halloran | 08 July 2019 Ericsson and Liberty Global have announced a successful trial to deliver gigabit broadband and linear TV to residential customers over a wireless trunk link.The trial aimed to prove the benefits of faster network build, reduced build costs and high-speed broadband in rural or low capacity areas. It was said to demonstrate how service providers can significantly reduce build costs and avoid civil engineering works by using a wireless trunk link instead of laying a traditional fibre trunk underground.Ericsson said that with the cable industry showing rapid growth within the FTTH domain, there is increased pressure on service providers to deliver more connections in a minimum amount of time and at the lowest possible cost. In addition, the industry migration to digital access networks in the coming years will also require the ability to connect a much broader set of technology applications.Liberty Global carried out the trial within their Virgin Media UK business. Virgin Media believes that build costs can be reduced by up to 90% as a result of the wireless trunk link.The distributed access architecture (DAA) decentralises and virtualises certain network functionalities to create a more software-defined network and bring digital fibre signals closer to premises.
