4G Will Drive the Need for Class 4 Backhaul Antennas in India

2013 saw an 87 percent increase in Indian mobile data traffic. With 4G services launching throughout 2014, we can only expect that this number will grow even more. With India seeing over 28 million new mobile subscriptions in Q1 2014 and the penetration rate still only at 63 percent (based on figures from the June 2014 Ericsson Mobility Report), carriers are facing unprecedented pressure to maintain a backhaul network that is robust enough to support this growth while meeting consumers’ high expectations on quality of service.Class_$_Threshold_Degradation

Back to Basics in Microwave Systems: Cross-Polar Discrimination

Microwave_Tower_AndrewIn the last “Back to Basics” blog post, Derren Oliver wrote about the ability of an antenna to focus the radio waves in the main beam, hence maximizing the signal level and reducing the interference to and from other links. Here, I’ll be explaining the microwave antenna’s ability to maintain radiated or received polarization purity between horizontally and vertically polarized signals. This is called cross-polar discrimination, or XPD.

In transmit mode, XPD is the proportion of signal that is transmitted in the orthogonal polarization to that which is required. In receive mode, it is the antenna’s ability to maintain the incident signal’s polarization purity.

For example, if a perfectly vertically polarized signal (containing no horizontal component) were incident upon a single polarized receive antenna, electrical and mechanical imperfections will introduce a small amount of ellipticity to the polarization of the signal. The signal can be thought of as having both vertical and horizontal components. The ratio of the consequential horizontal to vertical components is the XPD.


Infrastructure CapEx Versus OpEx

IABlogIntelligentBuildingsImageWhen people ask me what they should look for in a network infrastructure solution, I always tell them to consider performance and quality. Our studies have shown that these are the top two concerns; however, price or cost is never far behind. "No surprise there," you might say; however "price," "cost" and "value" can all mean different things depending on the scope and vision of what the user is hoping to achieve.

To determine the optimum choice when comparing relative costs of different solutions, organizations must evaluate their own application needs. They must also consider the various advantages of each solution and their relative importance. Cost, ease of installation, moves and arrangements, current and anticipated applications, and the expected life of the system are typically major decision factors.


Today’s IT Landscape Described by Philosopher 2,500 Years Ago

HeraclitusThe philosopher Heraclitus once said, “Nothing is permanent except change.” Given the rapid evolution of technology and the way information is accessed, it seems to me that the philosophy of Heraclitus certainly applies to today’s IT industry.

As usage of mobile devices increases, we are seeing a rise in the demand for anywhere, anytime connectivity. Mobile devices have become critical to people’s work lives. They are used by: professionals in business enterprises to work on-the-go, patients and doctors to access medical records remotely, companies to showcase their products and solutions, video streaming, and students for better collaboration with peers and teachers for exam preparation. Enterprises are starting to take notice of the growing bring your own device (BYOD) trend and redefining their IT policies to accommodate it.

College-Wireless-compressedBesides satisfying LTE demand in the macro network, wireless operators are facing challenges in meeting customer expectations at large venues such as stadiums, arenas and on college campuses. It is estimated that up to 80 percent of mobile data connections take place inside buildings—homes, businesses, restaurants, arenas, you name it.

To improve wireless network performance inside buildings, operators often rely on distributed antenna systems (DAS). DAS is simply a network of antennas, distributed throughout the building, which improves network performance inside (and in some cases, also outside) the venue. The various amplifiers, or remote units, are typically connected to the DAS head-end system using single-mode fiber-optic cable. Most DAS installations including CommScope’s ION series support multiple bands, operators and technologies in one platform and infrastructure.


Consider a World without Standards

World without StandardsHave you ever wondered what it would be like if the world operated without the common standards? Most standards are developed by independent organizations with representatives from many of the vendors who sell or manufacture products. These standards bodies meet at regular intervals and create work groups to develop common standards that all the vendors adhere to. Can you imagine a world without cross-vendor interoperability?  Wouldn’t that be a nightmare?

A typical work day, in a world without standards, would probably look something like this:


Protect Your Wireless Network from PIM

Tower ClimberNo wireless operator can afford to ignore pervasive and system-wide problems that impact network performance—especially those that will only get worse over time as networks become more complex. One such disruptive problem that continues to grow is passive intermodulation (PIM).

PIM results when two or more wireless signals mix together and create disruptive frequencies that cause interference or degrade signal transmission in wireless networks. This common phenomenon is well known in the industry and recognized by RF engineers as a real obstacle to network efficiency.


What Is Meant By “Purpose-Built” Data Centers?

Purpose-Built Data Center on DemandLike many of you, I live in a house designed by someone else. It was built almost three decades ago to the specifications of the previous owner; however, the layout is something my wife and I felt was comparable to our vision of what we wanted our home to be. We did not have the money to purchase the land and design our home from the ground up, so we have spent the past few years upgrading and outfitting the house to meet our tastes and needs.

In the data center world, I am familiar with modular data centers but was not familiar with the term “purpose-built” data centers. This is a term used to describe CommScope’s Data Center on Demand™ solution. Today - as hard as it may be to believe- you can have a data center built from the ground up, to your specifications and needs, in only a few weeks. This is the meaning behind the “purpose-built” data center.   


Broadband Success in Michigan

Merit Network 1In remote rural areas of Michigan, a lack of backhaul infrastructure limited the availability and performance of affordable Internet service. Community institutions (i.e., schools, hospitals, libraries and government organizations), businesses and homes were left with Internet speeds far below their needs. Something had to be done—enter Merit Network, Inc. 

Merit Network stepped in to solve the problem with the Rural, Education, Anchor, Community and Healthcare—Michigan Middle Mile Collaborative (REACH-3MC) initiative. When the American Reinvestment and Recovery Act of 2009 was signed into law, Merit saw the available federal funding as an opportunity to address the broadband shortfalls throughout Michigan. This non-profit organization could finally realize its nearly 50-year dream of bringing state-of-the-art broadband services across thousands of acres to rural areas of Michigan.

To accomplish such a feat, Merit Network selected CommScope as its fiber-optic partner for the 2,300 mile build-out. Prior experience and a diverse range of solutions ultimately convinced Merit that CommScope understood complex broadband deployments.


Supporting Wireless Subscribers in Times of Crisis

COW solutionWireless communications are an intrinsic part of life almost everywhere in the world. Hopefully your service is so good that you almost never have problems and can take it for granted. That’s what wireless operators strive to achieve. But in many parts of the world, especially those experiencing natural disasters or war, wireless service is anything but certain and reliable.

Sadly, news reports are filled daily with stories of armed conflicts, earthquakes, hurricanes, and other natural disasters disrupting people’s lives. Such situations often force people to flee conflict zones and devastation areas as refugees. Among other major concerns such as shelter, food and water, refugees need their mobile devices to work in order to stay connected with family. Large migrations of people challenge operators with sudden, highly concentrated numbers of users in one area. Operators often turn to COWs (Cell on Wheels) or other temporary cell site solutions to bolster wireless coverage and capacity in these areas.
