When a new copper or fiber cabling technology is developed, it’s only natural to assume it was designed to carry higher speeds in support of the seemingly endless need for more bandwidth. While that is usually a safe assumption, there are instances where new media types are developed to provide more cost-effective transport for lower speed applications.
Such is the case with the activities around single pair Ethernet applications standards. This is certainly not a new topic, as this technology has been standardized and is in use in the automotive industry and in several industrial applications.

A colleague told me last week that his kids weren’t
interested in data centers and fiber network intricacies. “As long as this
works, I couldn’t care less,” said one teenager, holding up his cell phone. That’s
the attitude we’ve developed about electricity, clean water, air or car
transportation, shipment logistics, even food supplies and public safety. These
services are so common they’re considered utilities, and we rarely think about
them. A massive construction effort is underway: the digital infrastructure
project is as important as the foundation of a house, yet most people don’t
know it’s there.
Foundations are critical in any industry. The original
masons were builders, skilled tradesmen who guided their craft, networked, trained
others, and exchanged knowledge and techniques to help improve the trade. The
institutions that stood on the foundations built by the masons conducted the
business, entertainment, culture, economics, and information exchange that have
driven human advancement and prosperity for the last thousand years.
It’s no secret that rural
fiber deployment has always been tough. It’s the age-old equation: not a lot of
people=higher cost to connect. There is no question that demand is there;
however, what’s a carrier to do?
For one, they need to be willing to invest in
the time and money it takes to deliver the services. The “big guys” usually
have both, but don’t want to take the leap because the return on investment is
not there. That means the smaller telecommunications companies that normally
can’t compete with the larger ones now have an opportunity to swoop in and save
Think about all the challenges capacity planners must face when it comes to forecasting and planning for efficient mobile networks. Over-dimensioning with too much network capacity is unforgivably wasted cash—while under-dimensioning is a catastrophic revenue loss!
As per the Shannon-Hartley theory, capacity dimensioning is a three-dimensional model. One should address the densification, efficiency and spectrum domains simultaneously to deliver a complete and optimized solution.
While researching for my blog
on consumer interest in the Internet of Things (IoT), I came across numerous
statistics and examples highlighting increased industry investment in smart
devices. For example, Accenture
estimates that by 2020 corporations will invest a total of $500 billion per
year in IoT technology. So, as consumers crave IoT technology to save time,
quickly access information and enhance efficiency, corporate enterprises are
becoming more and more interested in IoT. They want to exceed consumer expectations
by quickly and efficiently providing products, services and positive customer
experiences—with real-time access to insightful consumer data.
One of the great things
about my job is that I get to visit with customers and see how they solve
problems. People are so creative! When faced with difficult challenges, tight
budgets and short timelines, human beings are marvelous problem solvers. But even
genius quick-fixes don’t always produce the most reliable long-term solutions
to difficult engineering challenges like deploying network devices in outdoor
environments. The outside world, which can include weather, interference or
poor design, can truly be brutal on electronics devices.
Case in point: recently a
major university in the U.S. called CommScope to help with a network of
security cameras in a section of campus causing almost daily problems. When we
arrived, 10 of the 38 cameras were down, and the customer had been trying for a
week to bring them back up with no success. They told us that was common, and it
made the system almost unusable for the police department who needed these
cameras to work.
We all want to be connected. At home and at work. The ability to access content whenever we want and wherever we are is the new expectation. But as we connect more Internet of Things (IoT) devices to the network, the challenges increase.
One of the questions that is still unanswered is, “Who owns the network in the building?” According to a survey conducted by CommScope on in-building wireless, although 87 percent of building professionals say that it is imperative to have coverage in-building, 37 percent say network operators should be responsible while others say IT managers or building managers (23 percent and 21 percent, respectively). You can see that there is little agreement on ownership, which adds to the challenges.
In the below video, I talk more about these challenges and our upcoming educational seminars to help building managers and owners understand some of the expectations placed on building networks. See today’s press release about the “Evolution of the Workplace” workshops to register for these free events.
After about 10 months, and four stages of forward and reverse auctions, the 600 MHz incentive auction concluded on February 10, 2017 with the block assignment phase wrapping up on March 30. Once the dust settled, the final band plan ended with 70 MHz of spectrum divided among 50 wireless licensees for a gross price of nearly $20 billion.
Are you a movie fan? If you are, then you may assume that IMF
stands for Impossible Mission Force, led by Ethan Hunt in his Mission
Impossible movie series. However, it has a different meaning within the
networking industry, which is facing another seemingly impossible mission:
removing in-band interference. For this reason, CommScope has designed interference
mitigation filters (IMF). But don’t forget, “As always, should you
or any of your I.M. Force be caught or killed, the Secretary will disavow any
knowledge of your actions. This message will self-destruct in five seconds.
The Leakage Problem
Cordless phones, baby monitors, garage door openers, wireless home
security systems, keyless automobile entry systems, and other types of common
electronic equipment rely on low power non-licensed transmitters, or unlicensed
spectrum, to function. This can be a
headache for Wi-Fi users because the closer the non-licensed transmitter, the
greater the chance for interference, according to High
Tech Forum. No wonder you may have had
a bad connection the last time you were in the airport!
This blog post is part of our blog
series—Fiber Friday. Our subject matter experts will provide you with some
insight into the world of fiber optics, covering various industry topics.
With 5G on the way, service providers need to get the most bandwidth out of their current fiber networks.
One recent development in fiber technology is the increased use of passive
wavelength division multiplexing (WDM) devices. These devices allow carriers to get the most out of their valuable fiber assets.
Who can benefit from using WDMs? That’s an easy question to answer—all service providers. It helps best utilize their entire infrastructure and get it ready for 5G deployments.
In this vlog, I explain how this technology has evolved and the advantages it has created for service providers.
