The Importance of PIM – and How to Safeguard Your Network Against It

Pankaj Gandhi
Posted by Pankaj Gandhi on November 27, 2014

PIM-SureGuardIndia is home to one of the world’s fastest-growing and most dynamic mobile networks, with mobile subscriptions heading towards one billion and end-users demanding more bandwidth and capacity than ever. We are also seeing increased expectations for service levels and data usage rates.

Yet competition in the market compels us to keep capital expense (CapEx) and operating expense (OpEx) budgets under check even while addressing growth. This challenge drives operators towards better network performance management and optimal deployment of available resources. The limited availability of spectrum and spread across various bands further adds to challenges. One problem that grows hand in hand with network complexity is passive intermodulation, or PIM.


What You Need to Know about Non-traditional PON Architectures

Posted by Tom Anderson on November 26, 2014

PON-extenderAs the deployment of FTTH (fiber-to-the-home) solutions increases, real world network topologies are challenging the abilities of traditional passive optical network (PON) architectures. PON technology was conceived and standards were developed within the Institute of Electrical and Electronics Engineers (IEEE) and International Telecommunication Union (ITU) around a centrally located optical line terminal (OLT) delivering services over a single-fiber architecture to 32 optical network units (ONU) at a 20 kilometer range. Standards-based optics have been developed to extend that range to 30 and 40 kilometers, providing good solutions for simple range extensions while keeping the optical distribution network (ODN) truly passive.

Now, it should be noted that 64 and 128 splits are supported in the traditional PON architectures as well. Those traditional PON architectures are quite suitable for delivering the benefits of PON to the majority of network operators’ subscriber base; however, there are situations for which those solutions are not a perfect fit. For example, areas with limited fiber availability and deployments needing to provide service beyond the range of traditional PON are driving the need for alternative answers. This challenge demands a solution and here are three ways CommScope is actively engaged in solving these problems.


Hot Topics in Wireless Networks

Two things stood out to me at LTE North America in Dallas, Texas last week: small cells and 5G. I heard those words a lot and saw a number of presentations and panels related to them. Questions remain to be answered for both subjects. Will small cell deployments accelerate rapidly in the near future? If so, where and how and by whom? What about 5G? Who will define it first? And who will deploy it first?
 

Making Splitters and Couplers Easier to Deploy

Tom Nyman
Posted by Tom Nyman on November 24, 2014

Nyman_Splitter_ImageThe pressure on multiple system operators (MSOs) has never been greater because subscriber expectations have never been higher. Whether streaming digital video, high-speed broadband internet, or Voice over Internet Protocol (VoIP) telephony, the expectation is 100 percent uptime – 24/7 – wherever and whenever. It’s no surprise that service reliability is one of the biggest variables when it comes to increasing average revenue per user (ARPU) and decreasing churn.  

At the headend, MSOs have invested heavily in upgrades to increase redundancy and eliminate service interruptions; however, unless the same criteria and careful considerations are used in selecting the best home connectivity components, the investment will not pay off. This means that even the least expensive components, like splitters and couplers, must be chosen based on their reliability, RF performance and ease of use, and not just their price. 


Time to Take Fiber Optic Technicalities Seriously

James Donovan

Scattering_Bending_ImageWhen it comes to optical transmission, it is easy for discussion about data rates, bandwidth, loss, fiber core size and the distances supported to be misleading. To make the right choice, it pays to know the language. I would like to identify and explain some of the terminology one might use if he or she is a fiber optic infrastructure specialist.

Channel or link loss is the total path loss or attenuation between the transmitter and receiver. It is the sum of various loss mechanisms: scattering, microbending, macrobending and interconnection. These limit the maximum system length and the number of connections allowed. 

Scattering causes the intrinsic fiber loss dominated by what is known as Rayleigh scattering, which results from variations in density and compositions of the glass. This loss varies with the wavelengths of light applied.


Asia Pacific Could Lead the Way in Intelligent and Green Buildings

GreenBuildingThere is an increasing awareness and support for the growth of green and sustainable buildings in the Asia Pacific region. This is a result of government initiatives and a large number of enterprises that are putting more emphasis on the development of buildings that are both intelligent and green. These buildings would be more resource efficient, occupant smart and optimized for space. They will also bring about cost savings in the long run and achieving high levels of energy efficiency. All this would impact the environment in a positive way.

 


How to Sharpen Your Data Center Intelligence

DataCenterIntelligenceThe human mind is an extraordinary instrument for knowledge and insight. Keeping the mind sharp requires exercising its critical thinking ability. In fact, there are several products on the market to help exercise the mind and keep a good sharp focus. Some of these products come in a pill form and some are games or puzzles. Believe it or not your data center, like the mind, can lose its focus and lack a true understanding as to what it needs to function at its best.

 


The Art of Sector Sculpting

Mike Wolfe
Posted by Mike Wolfe on November 13, 2014

Sector-SculptingSector sculpting. That’s a term we use at CommScope for the art of delivering precise antenna patterns that define the sectors of a wireless cell site. We sculpt sectors by supplying antennas with different types of radiation patterns, including multibeam antennas, and with remote electrical tilt (RET).

What’s the benefit? More precise delivery of sector patterns improves the signal to noise ratio (SNR), which improves network performance especially for LTE technology. The types of antennas chosen impact the amount of weight and wind load on cell towers, which are also important considerations.


Unleashing the Real Value of DCIM

Posted by James Sherrin on November 11, 2014

DCIMValueTo unleash its true value as a management tool, a data center infrastructure management (DCIM) solution must be able to share information with a plethora of other systems that exist inside and outside of your data center. Integration capabilities are an absolute necessity for a truly broad-based DCIM platform. Many organizations may not fully understand the importance of this aspect to a DCIM solution.

 


Investing in Wireless Network Resilience

China-Reliability-CenterAt CommScope, we know how important it is to our customers to have reliable, resilient RF Path solutions. Those solutions are the backbone of their wireless networks and their subscribers’ overall wireless experiences. Poor reliability means more network performance issues, more costly maintenance work and more subscriber churn.

In our ongoing campaign to offer highly tested, resilient RF Path infrastructure, CommScope has recently opened its newest reliability center in Suzhou, China. For the first time in the region, all our antenna testing can be done on site in one location—a great time-saver for us and our customers. The new reliability center supports our product design and manufacturing operations in China, India and Australia. It joins our other reliability testing centers located in Buchdorf, Germany; Agate, Italy and Richardson, Texas.
