Identifying and Locating Short-Duration Interferers

The ability to efficiently detect, analyze and locate sources of radio-frequency interference has become increasingly important in modern wireless networks. Unlike constant or near-constant sources, so-called short-duration interferers can only be detected for brief periods of time and therefore special tools and techniques are often required when searching for these types of signals.

Voice Quality with ITU P.863 ‘POLQA’

ITU P.863 ‘POLQA’ is a new measure for objective speech quality assessment. In this white paper, we discuss in-depth the development and working of P.863 and its implications for quantifying speech quality in mobile networks.

An Introduction to Measuring Quality and MOS Testing

Obtaining an accurate estimate of voice or video quality depends on many factors. First and foremost, it depends upon how the ‘experiment’ is defined and executed. Many techniques for assessing voice and video quality exist today with the most popular – and least understood – being the Mean Opinion Score (MOS). This white-paper takes a… Read more »

Testing and Benchmarking of Video Services

Popular video services such as NetFlix, Hulu, iTunes, etc, are transitioning from cable and satellite delivery systems to mobile technologies. Cisco Systems predicts that 66% of all mobile data will be video by 2014. This paper discusses challenges and implications for mobile operators in delivering high quality video services.
