Converging the Access Network

Most of the hot trends in telecom transformation are software-based -- software-defined networking (SDN), network functions virtualization (NFV), orchestration, automation, software-defined wide area network (SD-WAN), analytics, edge/fog computing, network slicing and more.

Yet hardware isn't completely out of the picture. Operators are evolving the fiber access infrastructure that will be the foundation of the transformed network. A confluence of drivers and enablers lead to evolving business models and architectures for the fixed access infrastructure and renewed investment in fiber access networks.

Difficulty in building a compelling business case for new access fiber helps feed the digital divide. Part of the problem has been that large operators historically tended to silo their access fiber assets along the lines of their internal organizational silos. Thus, there were purpose-built fiber networks for fiber-to-the-anything (FTTx), business services, and wireless backhaul/fronthaul/DAS. These practices are sub-optimal from a capex and opex perspective.

More importantly, fiber access network builds that are considered not viable -- based on the revenue projections and risks of one business -- are often viable if based on revenue projections and risks of multiple businesses. By not sharing infrastructure, operators forego revenue-generating opportunities and good margins.

Acute needs for 'x-haul' for 4G mobile densification and 5G, Internet of Things (IoT), business services upgrades and Gigabit broadband is driving a resurgence in access fiber construction. Operators have come to recognize the inefficiency of siloed infrastructure. A converged, fiber-based fixed access platform has become a strategic necessity.

A new Heavy Reading report, Converged Access Infrastructure, examines the trend toward converged infrastructure in the access network, exploring:

  • Evolution of the fiber access network, past and future

  • Drivers and enablers for access network convergence

  • Financial models for building new access infrastructure

  • How innovation in the outside plant reduces capex for new construction

  • Architectural trade-offs for converged access

  • Why converged access is joined at the hip with SDN/NFV/white box and XGS-PON/NG-PON2

  • Strategic implications for operators, vendors, local governments and investors

Access network convergence is one of the key trends that will define the network of the 2020s and beyond. While it might not be as visible as some of the others, its impact will last for many decades, and its ultimate demise will be from ageing rather than obsolescence. This infrastructure will be the foundation for 5G, IoT, Gigabit broadband, SD-WAN and other services yet to come.

How Many Years Until Positive ROI?
While this sounds great, the cost of fiber and actual installaton will probably mean it's several years before most telecoms show a positive ROI from this type of investment.

Understanding the full experience of women in technology requires starting at the collegiate level (or sooner) and studying the technologies women are involved with, company cultures they're part of and personal experiences of individuals.

During this WiC radio show, we will talk with Nicole Engelbert, the director of Research & Analysis for Ovum Technology and a 23-year telecom industry veteran, about her experiences and perspectives on women in tech. Engelbert covers infrastructure, applications and industries for Ovum, but she is also involved in the research firm's higher education team and has helped colleges and universities globally leverage technology as a strategy for improving recruitment, retention and graduation performance.

She will share her unique insight into the collegiate level, where women pursuing engineering and STEM-related degrees is dwindling. Engelbert will also reveal new, original Ovum research on the topics of artificial intelligence, the Internet of Things, security and augmented reality, as well as discuss what each of those technologies might mean for women in our field. As always, we'll also leave plenty of time to answer all your questions live on the air and chat board.
