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.

  1. Fronthaul
  2. Scalability
  3. Densification
  4. Virtualization
  5. 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>

Radio Over Fiber Paves Way for Future 5G Networks

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>

Why you should use cloud direct connect

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>

A goal realized: Network lobbyists’ sweeping capture of their regulator

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>

Broadband gaps impact every member of Congress

By Adie Tomer – Digital connectivity is the glue of the modern American economy. From rural farmers to city business leaders, every industry relies on broadband to track markets, connect with customers, and sell their products. The American household is equally reliant on broadband, whether its kids bringing home their digital classrooms, adults telecommuting to their jobs, or whole families streaming video content to their televisions. And governments at all levels can use digital platforms to improve service delivery and reduce costs.

Yet for all of broadband’s economic benefits, the country continues to face a significant digital divide at the household level.

Without seamless digital connectivity, many households are at-risk of falling further behind in the country’s advanced economy.

While Congress considers policies related to expanding broadband availability, there is little to no legislative activity related to broadband adoption. more>

You Can’t Solve These Problems on an Ad Hoc Basis

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

In 2017, Cost Per Bit Exceeds Revenues

By Carol Wilson – This is the year when most telecom network operators will see their revenue-per-bit fall below their cost-per-bit, says a veteran industry analyst, and that financial reality is going to reverberate through the industry for at least the next two years, prompting further consolidation and cuts by network gear makers, as operator capex budgets shrink.

Companies such as AT&T Inc. (NYSE: T) have been very open in saying the revenue-cost crossover drives their aggressive transformation efforts, because they recognize it is impossible to meet bandwidth requirements of the future doing things the way they’ve been done in the past.

That will mean continued price pressure on equipment vendors, CIMI Corp. CEO Tom Nolle, maintains. He points to declining revenues, quarter over quarter, for companies such as Cisco Systems Inc. (Nasdaq: CSCO), and to the fact that Huawei Technologies Co. Ltd. is alone among vendors in growing its revenues because it is a price leader in many categories.

The analyst expects 2017 and 2018, at minimum, to be pretty bleak years for the telecom equipment space. more> https://goo.gl/ayoS7W

ITU releases annual global ICT data and ICT Development Index country rankings

ITU – The Measuring the Information Society Report is widely recognized as the repository of the world’s most reliable and impartial global data and analysis on the state of global ICT development and is extensively relied upon by governments, international organizations, development banks and private sector analysts and investors worldwide.

“To bring more people online, it is important to focus on reducing overall socio-economic inequalities,” said ITU Secretary-General Houlin Zhao. “Education and income levels are strong determinants of whether or not people use the Internet.”

An increasingly ubiquitous, open, fast and content-rich Internet has changed the way many people live, communicate, and do business, delivering great benefits for people, governments, organizations and the private sector. However, many people are still not using the Internet, and many users do not fully benefit from its potential.

  • Most people have access to Internet services but many do not actually use them.
  • The full potential of the Internet remains untapped.
  • Access to the Internet is not enough; policy-makers must address broader socio-economic inequalities and help people acquire the necessary skills to take full advantage of the Internet.
  • Many people still do not own or use a mobile phone.
  • Affordability is the main barrier to mobile-phone ownership.
  • Asia and the Pacific has the lowest average purchasing power parity (PPP) $ price for mobile-cellular services of all regions.
  • Fixed-broadband prices continued to drop significantly in 2015 but remain high – and clearly unaffordable – in a number of LDCs.
  • Mobile-broadband is cheaper and more widely available than fixed-broadband, but still not deployed in the majority of LDCs (Least Developed Countries).

Mobile phone adoption has largely been monitored based on mobile-cellular subscription data since these are widely available and regularly collected and disseminated by regulators and operators.

At the end of 2016, there are almost as many mobile-cellular subscriptions as people on earth and 95% of the global population lives in an area that is covered by a mobile-cellular signal. However, since many people have multiple subscriptions or devices, other metrics need to be produced to accurately assess mobile uptake, such as the number of mobile phone users or mobile phone owners. more> https://goo.gl/L3Nh90

AT&T opens itself up to activist attack

By Rob Cox – AT&T’s $85 billion takeover of Time Warner looks like a deal from another era. Back around the turn of the millennium, corporate chieftains roamed the global capital markets freely, buying rivals at random and running roughshod over shareholders, unencumbered by vigilant boards or uppity investors.

In this profligate epoch, the Hollywood studio was a popular plaything.

In most sensible acquisitions, a buyer promises to reduce expenses in the combination, diluting the financial impact to its owners. AT&T does say it will target $1 billion in savings, but given the absence of overlap, it’s a dubious pledge.

“Most of these,” posits Cowen analyst Colby Synesael of the synergies, “will come from what will likely be meaningful headcount cuts within AT&T that were likely to occur regardless of whether AT&T was acquiring Time Warner.”

What can embittered AT&T shareholders do? They don’t get to vote on the Time Warner deal, thanks to the crafty workings of Stephenson and the board. Beyond a rival bid that rescues them or regulators squashing the plan, investors determined to put a stop to the madness could enlist the services of a modern-day white knight of sorts: an activist. more> https://goo.gl/qH2Vfl
