5 key wireline network improvements needed for 5G
By Brian Lavallee – Ask an end-user about how their phone connects to the network, and they’ll likely only talk about cellular or wireless technology, which is also where most of the current 5G industry hype is focused, and for good reason, as this is the first part of the network to be upgraded. However, the reality is that RAN (Radio Access Network) only makes up a small portion of the end-to-end path that data from a connected device must travel to provide connectivity. The rest of the path is primarily a fiber-optic transport network.
With 5G coming soon, featuring data rates as much as 100 times faster than what’s currently available, the wireline infrastructure that connects end-users (man and machine) to accessed content residing in data centers, must be ready to support upwards of 1,000 times more data flowing across it.
How can network operators prepare? Well, here are five key areas within the wireline network that will need to be upgraded and modernized to support 5G.
- Network Slicing
The move to 5G won’t be a simple network upgrade. It’s a long journey with a high-performance wireline network as the critical component to commercial success for both 4G strategies and the evolution toward 5G. more>

By Nitin Dahad – A manufacturer of III-V photonic devices claims to have proven the feasibility of 60-GHz radio over fiber (ROF) transmission at a 1,270-nm wavelength, paving the way to potential solutions for 5G networks.
CST Global, a Scotland-based subsidiary of Sivers IMA Holdings AB in Kista, Sweden, carried out the feasibility study as part of an EU Horizon 2020 research project. The project, iBROW (innovative ultra-broadband ubiquitous wireless communications through tera-hertz transceivers), was led by the University of Glasgow and managed within CST Global by research engineer Horacio Cantu.
The company says that ROF networks are emerging as a completely new and promising communication paradigm for delivering broadband wireless access services and fronthaul at 60 GHz, relying on the synergy between fixed optical and millimeter-wave technologies. ROF technology enables RF signals to be transported over fiber across kilometers and can be engineered for unity gain RF links. Hence, it is thought that it could do a lot to ease spectrum constraints, and it can replace multiple coax cables with a single fiber-optic cable. Among several benefits, ROF could also enhance cell coverage. more>

How is change management the key to successful cable infrastructure modernization?
By Susan Friedman – The winds of change are blowing for the Cable/MSO Industry. And it’s all happening faster than anyone thought. Last month, cable industry gurus met in Denver for Light Reading’s 11th annual Cable Next Gen Technologies and Services conference, and it was clear embracing change is critical to meeting the end-user’s needs.
We’ve heard a lot about the impact of streaming services and cord cutting. But it was clear from discussions at the show that consumers are not abandoning cable, they are changing their consumption habits. They are now buying fast and reliable internet services, and lots of it. Consumers just can’t get enough of connected devices and the Smart Home is only smart when connected to the internet.
Here is a big change, the internet is now the epicenter of a cable operators network, not video delivery. According to Leichtman Research Group, cable rules U.S. broadband more than ever, with subscribers up 2.7 million in the last quarter of 2017. That’s 64.4% of the total market for internet services.
Technology change is also a disruptive cycle for the cable workforce, subscribers, or anyone trying to navigate thru a utility work zone. more>

datacenter.com – Cloud direct connect allows enterprises to access public cloud services (i.e. Amazon, Google, Microsoft, TencentCloud, etc) over a dedicated, private connection rather than over the public Internet. The benefits of direct cloud connections to your own network include greater reliability, better performance (better speed, lower latencies) and a higher security than typical connections over the Internet.
The costs of WAN and public Internet connectivity can be significant. The cost of moving a lot of data to your cloud provider vary per provider, but often are expensive. By using a neutral data center, you have access to multiple carriers who can provide you the necessary public Internet connections and direct cloud connect services. By segmenting the various network workloads, you can often realize savings in bandwidth and reduce the costs of moving data to your public cloud provider.
By replacing a “best effort” network, such as the public Internet with a direct connection to your cloud provider, you gain consistency in throughput and performance. As the mathematical principle states, “the shortest distance between two points is a line.” By using cloud direct connect services you’re connecting to the cloud provider in a straight line and increasing your performance. more>

By Tom Wheeler – “Here’s how the telecom industry plans to defang their regulators,” a September 12, 2013 Washington Post headline announced. “[T]elecom giants including Verizon, AT&T and Comcast have launched multiple efforts to shift regulation of their broadband business to other agencies that don’t have nearly as much power as the FCC,” the article explained.
The companies’ goal: to move regulatory jurisdiction from the Federal Communications Commission to the Federal Trade Commission (FTC). Strategically, it is a brilliant sleight of hand since the FTC has no rulemaking authority and no telecommunications expertise, yet the companies and the policymakers who support them can trot out the line that the FTC will protect consumers.
With this vote, the FCC walked away from over a decade of bipartisan efforts to oversee the fairness and openness of companies such as Comcast, AT&T, Charter, and Verizon. These four companies control over 75 percent of the residential internet access in America, usually through a local monopoly. Henceforth, they will be able to make their own rules, subject only to very limited after-the-fact review.
The assertion that the FTC will be able to provide that protection adequately is an empty promise. The people at the FTC are good people, but they have neither network expertise, nor the authority to make rules. more>

By Sasha Cohen O’Connell – Resolving today’s most pressing cyber security and Internet governance challenges is dependent on the tech industry and the government working together on both policy development and policy implementation.
Specifically, collaboration is required to successfully research, design, debate, and ultimately implement effective solutions.
While there is overwhelming consensus on the need for collaboration, it remains a huge challenge. Why?
While many factors contribute to the problem, including differing incentive structures, cultures and business models, one critical element—organizational structure—is a significant and often overlooked hurdle that needs attention and creative solutions.
Most collaborations today are done by ad hoc teams of operational personnel, lawyers, government affairs departments, and/or trade associations or other outside third parties. This setup is neither efficient nor effective. more> https://goo.gl/B0j8RA
