Radio equipment at conventional cell sites is located at the base of the tower, transmitting RF signals via coax to antennas at the top of the tower. However, these coax-based feeders produce most problems in cell sites due to their inherent loss and susceptibility...
The communications industry's big push towards virtualizing network equipment, services, functions and applications is certainly much more than a fad.
Telecom carriers, cable operators and other service providers are increasingly seeking ways to trim capital and operating expenses, improve customer service,bring products to market quicker...
Self-organizing networks (SON) have interested the cellular industry for many years. Work in this area started in 2006 at 3GPP with initial studies on the general concepts and requirements. There was a clear impetus to study SON—networks were becoming larger and more complex, and...
Spectrum monitoring is a powerful tool that can be used to ensure that the RF communications we all depend on for both civilian and defense applications work, and work well. The need to make more effective use of our RF spectrum comes from a number...
Small cells are expected to be a central part of Ultra-Dense Networks and support more capacity, coverage and speed - but this can only come to fruition if they are financially viable for large-scale deployment. This requires a two-pronged approach: a new paradigm of...
Mobile data usage is on the rise – subscribers all over the world churn through gigabytes of streaming video, music, and social networking every month. Mobile network owners are scrambling to stay ahead of data demand by densifying their radio access networks with small...
Network functions virtualization (NFV) has made remarkable progress on many fronts. This includes market acceptance, architecture definition and supporting specifications. As a result, the industry will very soon move into the commercialization phase, leveraging the many business and technical lessons learned in proof-of-concept (PoC)...
Small cells, ranging from femtocells in consumer applications, through pico, metro and micro cells in enterprise, and urban applications, are revolutionizing the coverage, capacity and availability of wireless data services. The insatiable demand for more and faster data is driving increasingly rapid deployment of...
The use of the 60-GHz (V-Band) goes back to 2001, when the US regulator (FCC) adopted rules for unlicensed operations in the 57 to 64GHz band for commercial and public use. This very wide frequency band, with over a 7-GHz of continuous spectrum, makes...
The Internet of Things (IoT) holds a great deal of promise for the future on many levels. With projections for anywhere from 20 billion to 100 billion connected things by the year 2020, there is a great deal of revenue at stake over the...
Critical communications are moving with the times. Having been largely based on systems that support ultra-reliable voice, such as Tetra, they are now shifting to IP and broadband. The choice of platform is not a simple one when a lost connection could mean a...
Today, DNS needs to be flexible and dynamic to adapt to the existing network and application conditions and to deliver the best experience for subscribers and their content. With Intelligent DNS services, service providers can drive greater reliability, availability, flexibility, and security within the...
When it comes to determining the best fit for in-building or outdoor wireless needs, it is best to discount the hype and really think about what you are trying to accomplish. In all good practices we can come back to the fundamentals that say...
The MW82119A/B PIM Master from Anritsu is a family of high power, battery operated PIM test instruments designed for maximum portability. These instruments utilize a filter combiner to maximize RF efficiency and minimize battery consumption during use. The F1 and F2 frequency range for...
The radio access network is becoming more complex, with cell-site fronthaul architectures ranging from conventional coax to modern fiber. Fiber is increasingly prevalent in all types of cell sites including macrosites, distributed antenna systems (DAS), and small cells.
Spectrum congestion compounds this complexity. Congestion creates interference problems,...
Although smartphone users are quite satisfied with the multiple functionalities and the convenience brought by their devices, more and more users express concerns about the rather poor battery life compared to the previous generation of feature phones. For consumers, the battery life is one...
Service providers face the constant challenge of rolling out new technologies and upgrading networks while maintaining customer experience using existing tools and processes.
With the massive growth in data traffic driven by high speed broadband, social media and streaming video services, service providers are under...
BYOD: Evolving Best Practices for Validating APs and Controllers
This white paper takes a timely look at the mobile “Bring Your Own Device” (BYOD) phenomenon and what wireless LAN (WLAN) manufacturers and administrators are doing to mitigate its impact on application performance. Includes insights into...
Passive Intermodulation (PIM) testing is becoming more critical as cellular systems age and the carrier count increases. Anritsu’s PIM Master™ MW82119B combines a portable, powerful PIM analyzer with an optional Cable & Antenna Analyzer. With a large outdoor screen and easy-to-use user interface, the...
The rapid spread of smartphones and many new Cloud services in the last decade has led to explosive growth in mobile data traffic. Simultaneously, the new LTE and LTE-Advanced mobile technologies with faster data throughput are driving dramatic increases in mobile data traffic as well, naturally...
The use of multiple input multiple output (MIMO) severely complicates the process of measuring eNodeB power and modulation quality in LTE systems. The difficulties include the fact that spectrum analyzers have just one receiver, while two or more receivers are needed for complete demodulation...

Next Generation wireless networks (4G/LTE/LTE-Advanced) are being based on the premise of
100 Mb/s data transmission to the handset. Imagine being able to live stream 1080P HD video
to your device any time, anywhere, even as you are traveling by car (though not while in the
driver's...
