OPINION ACCESS NETWORKS
in 2015, titled, ‘Working Together: Te Synergies of Fibre and Wireless Networks’. As soon as those airwaves hit an antenna, they have to be combined and piped down a fixed connection as soon as possible. ‘Te common misunderstanding we see
when comparing the economic benefits of 5G and fibre broadband is that they are treated as two separate, independent technologies when in fact they are interdependent. Te future of very-high-capacity wireless networks will result in much more fibre being deployed, rather than less,’ stated Ronan Kelly, president of the FTTH Council Europe. Felten agrees. ‘From what we currently
know about 5G, it cannot exist without fibre,’ he said. ‘Te density of 3G antennas was roughly one per 10 square kilometres, the density of 4G is near to one per two square kilometres and projections for some possible 5G implementations suggest it will be one antenna for 500 square metres or even denser. Tese antennas need to be backhauled, and if they are to deliver speeds comparable to today’s fibre broadband offerings, they will have to be backhauled with fibre.’
Tis means 5G will emerge first and be
deployed faster in areas where fibre is already deployed, he says. It also means fibre will need to be deployed in areas where it is not available before 5G can deliver better service quality than 4G. Widespread deployment of fibre access networks will make the business case for 5G a lot easier as latest technologies, such as NG-PON2, are designed to allow multiple service types to share the same physical fibre. Pitching fibre and wireless technologies
Ronan Kelly
The future of very-high- capacity wireless networks will result in much more fibre being deployed, rather than less
against each other isn’t constructive, Kelly declares. ‘We won’t get 5G unless we have fibre available to support that technology … assertions to the contrary only serve to cause further confusion and misinformation. Te FTTH Council Europe believes far greater gains will be achieved when proponents for 5G deployment work together with the proponents of fibre to the home. Working together, the Gigabit Society vision – and all of the benefits that go along with it – will be realised much sooner.’ I wholeheartedly agree. Our broadband
future encompasses both wireless and fibre.l Pauline Rigby is editor of Fibre Systems

This white paper explores strategies to address the challenge of providing the highest level of network availability at the optimal cost for each service.
Simplifying Tier 2 Certification in Fibre Optic Cabling
By IDEAL Networks
The iOLM greatly simplifies Tier 2 OTDR certification and allows technicians with relatively little experience to certify and if necessary, analyze and troubleshoot fibre cabling regardless of the complexity of the link.
