Webinar report: identifying and eliminating interference in mobile networks
In mobile networks, interference is an unwanted unlicensed signal affecting the licensed channels, causing extra noise. Interference on the RF level translates into a lower Signal-to-Noise-Ratio (SNR), Received Signal Strength Indicator, Ec/Io, etc. From a subscriber’s point of view, interference is perceived as distorted audio or video, low data rates or dropped calls. In short: a bad user experience. For…Read More
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…Read More
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…Read More
The network never sleeps – how service quality monitoring ensures connectivity 24/7
Do you ever wake up in the middle of the night worrying whether your subscribers, critical staff, emergency services, and remote sensors still had connectivity with the mobile network? Many businesses and organizations rely on wireless connectivity for the security and efficiency of their organizations. They care passionately about connectivity and, with the emergence of IoT and 5G, their number…Read More
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…Read More
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…Read More
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…Read More
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…Read More
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…Read More
