Small Cells and the Evolution of Backhaul Assurance
Mobile-network bandwidth demands continue to increase with no end in sight, driven by the proliferation of newer mobile devices such as smartphones and tablets. With powerful processors and operating systems, mobile applications require considerable network resources. In recent years, the Google Android™ operating system has further accelerated new product introductions from a variety of device manufacturers, resulting in a quadrupling of processor speeds. Averaging hundreds of thousands of new activations per day, Android and other powerful mobile platforms such as the Apple iOS and Windows have fostered an environment enabling the rapid introduction of new, interactive, video-based applications. Emerging machine-to-machine requirements, including sensor networks and connected car platforms, will add further traffic load to today’s mobile networks. READ MORE
Increasing the Lifespan and Reliability of Electrical Components
Heat is both a by‐product and one of the greatest enemies of electrical and electronic components. If not dissipated, this heat has the potential to cause early failures and malfunctions. Components commonly packaged in electrical enclosures, computer server racks, and other product compartments are the vital controls for drives and displays used in many industries.
The primary purpose of these electrical enclosures is to provide protection and safety for the components they house. If an enclosure is properly cooled, the components within can have a long and useful life. Without proper cooling, however, the components in these enclosures can be subject to damaging heat, shortening their longevity and reliability. READ MORE
Evolution of the Wireless Home
The connected home continues to evolve from basic connected home networks to a feature rich collection of CE devices, broadband-enabled services, and multifunctional set-top boxes and residential gateways. Existing and traditional services are continually offering more: more functions, more speed, and more consumer benefits. CONSUMER PREFERENCES AND DEMANDS are in large part driving the technological advances in devices and services. READ MORE
The Real Healthcare Changes On The Way
Healthcare has been a hot topic since the passage of the Affordable Care Act, now referenced by both parties as “OBAMACARE.” Efforts to repeal it ebbed briefly after an unsuccessful Supreme Court challenge in June 2012, and all sides turned to the November elections as the ultimate referendum on the fate of the legislation. With President Obama’s successful reelection, Obamacare will remain largely intact and have a sweeping impact on the U.S. healthcare system when most terms are phased in during 2014. However, the healthcare industry was bound to experience funda¬mental changes, regardless of the election’s outcome. READ MORE
Reducing the Cost of Fiber Deployment With Pushable Fiber
Few would argue that it is important to ensure that your network is strong, reliable and quickly restorable. However, the debate centers on how to build a network that isn’t too costly to deploy or operate.
With 80% of a telecommunications build being spent on labor, it is critical to the containment of deployment costs that a thorough analysis of how to control labor costs be undertaken. A deployment will require a staff of planners, engineers, field crews and construction forces that are knowledgeable about the type of services to be offered and how they are to be delivered.

Take the Bite Out of Broadband Networks
Logical, Cost-Effective Solutions, Practices and Methodologies Across the Entire Passive Network
FTTH deployment technologies are many and additional are in development. Service providers must evaluate and determine which technologies are best for them, whether its BPON, GPON, and Active Ethernet or the emerging technologies of GPON-10GB, WDM-PON, NG-PON, All-IP triple play, and even RFOG. Within this evaluation, the service provider must be aware and carefully weigh the cost associated with these technologies against the insatiable thirst for bandwidth that their subscribers demand. The FTTH provider is faced with many choices. Do they put in the safe and generally accepted infrastructures – but then worry about the costs and timing of future upgrades? Or, should they put in the cutting edge technologies and deal with the costs and challenges of being an early adopter? Or, do they do something in between? READ MORE
T-BERD(r)/MTS-4000 Class of Service (CoS) Test Suite
The development of new Internet Protocol (IP)-packet based, so call Triple-Play, services (voice, video, data) delivered over the telco Access Network places new demands on network designs. Each of the services has their own specific quality of service (QoS) requirements, and all have varying bandwidth demands that are dynamic in nature, and, as a result, require prioritized treatment of the three services. In the access network, where bandwidth (BW) is often limited (digital subscriber loop [DSL] links, for example), BW allocation and control is critical. Furthermore, the mix of services supported must match the customer subscriptions and thus expectations: the number of high definition (HD) video streams, standard definition (SD) video streams, and voice calls supported simultaneously, and the amount of BW is provided for data service.

Fuel Cell Basics for Communications Industry Professionals
Fuel cells are used today in a variety of applications ranging from backup power for telecommunications and government industries to material handling vehicles and recreational vehicle support systems. They are touted as a clean, green alternative to batteries and combustion engines, capable of passing the most stringent air quality standards. They are famous for their role in the Space program since the late 1950’s as a source of both power and water for crew consumption. But what are fuel cells, how does it work, who uses them and why should you care? READ MORE
Multi-Dwelling Unit Fiber Unit Deployment
Billions of dollars are spent annually delivering high speed fiber networks to Multi-Dwelling Units (MDUs) — apartments, condos, and student-housing — across North America. Service providers recognize the rich potential returns on a fiber investment in such high-density markets. Fiber connections will bring fast, reliable, content-rich services to millions of households. However, poor planning of fiber network interfaces and service delivery to a consumer's media devices can leave everyone, from the builder/developer and building owner to the service provider and tenants/subscribers, frustrated.

Understanding Power Factor and Input Current Harmonics in Switched Mode Power Supplies
The proliferation of AC-DC switched mode power supplies has resulted in strict limits being imposed on AC input current power factor and harmonic content. The electronic system designer must take these into account in developing hardware requirements. A sound understanding of typical power factor correction circuit performance and dynamics as a function of line and load will aid in this task. READ MORE
Fiber Optic Electrical Protection for Stand Alone PCS and Other Radio Sites
There are four major reasons to use fiber optic systems for radio tower communications:
- Fiber optic links eliminate transferred potentials 1 during lightning induced Ground Potential Rise (GPR) conditions.
- Fiber optic links are immune to high energy Electro Magnetic Pulse (EMP) induction from lightning; both within and external to the radio site.
- Fiber links provide total dielectric isolation for all circuits (backhaul) between the tower radio and the serving telco copper based network.
- Fiber optic links provide the highest level of worker safety and service reliability.
This paper addresses these four major reasons for using fiber, and the basic principles for providing overall electrical protection for stand alone radio towers. READ MORE
