Service quality monitoring explained in an interactive infographic

With the provision of robust wireless connectivity to people and machines becoming a critical element, a new way of efficiently and independently monitoring the network 24/7 is required. Service quality monitoring empowers businesses and government organizations to independently verify the performance of their network in real time and 24/7. Organizations that rely on the availability, capacity, and latency of the…

Proofing and optimizing a network’s readiness for video transmission

In previous entries of this blog series about the challenges of mobile video services, we discussed video quality as a perceived metric, how it can be measured, and how quality measuring algorithms work. To conclude the series, this post focuses on how to apply a video quality measure to quantify video services as consumed by subscribers. What are the challenges…

The true view of your and your competitors’ networks

Hand in hand with the ever increasing demand for more network capacity and the soaring popularity of applications, particularly in real-time, mobile operators in mature markets are also facing a virtually flat subscriber penetration for the next five years. To win new customers, mobile operators are left with no other option than to beat the competition by providing better services…

What different models for predicting visual quality exist? What models are applicable for which test cases?

In a previous blog entry about the challenges of mobile video services, we discussed video quality as a perceived metric and how it can be measured subjectively in viewing sessions. In this post, we will take a closer look at automated video quality measurement methods, often called objective measurements, which are applied in real field video quality measurements. An objective…

Harmonizing user interfaces: single sign-on (part 2 of 3)

We all know the burden of having to remember the myriad of usernames and passwords we use to log in to various systems and applications. User accounts, e-mail, web sites, online banking – the list goes on. Some platforms require a username, others an e-mail address. Many applications have different password complexity requirements and password expiration times, and of course, you…

Smart macro network enhancements: antenna tilt optimization

Antenna tilt optimization is a cost-efficient and smart approach to increase the capacity in mobile networks. Today, operators have to focus more and more on data capacity and network densification. Also, particularly in urban and dense urban environments, macro cells need to be smaller and coverage needs to be limited. One important method to achieve this is antenna downtilting. It…

Identifying passive intermodulation

Passive intermodulation is nothing new. It has been an issue since the first commercial networks. In GSM, for example, whenever a PIM issue was present, network operators could easily re-allocate frequencies without affecting the service. With 3G and 4G, however, frequency re-allocation is no longer possible. PIM problems have to be dealt with. They have become even more important as…

Searching vs browsing: why the SmartMonitor is smarter

Good navigation and quick access to features are vital for the success of any web application. On the Internet, browsing is the primary navigation method on most sites, but as content grows it can become quite difficult to solve UX (user experience) challenges with a structured navigation alone. Creators and designers – whether of websites or other software user interfaces…
