Testing Perceived Video Quality in Mobile Networks – Part 2

As a continuation of the earlier video, Arnd Sibila explains in more detail how video quality can and should be tested using J.343.1. As a very robust algorithm, J.343.1 takes into account all video characteristics into a single score; e.g., coding, compression, rescaling artifacts, perceived freezing, etc.


Remote Radio Heads in Today’s Evolving RAN Environment

Radio Access Networks (RAN) have evolved considerably from mobile access networks of the past and are helping to drive the “densification” of mobile networks allowing mobile operators to keep up with the heavy traffic demands brought on by 4G/LTE. In this webinar, we look at the forces behind the evolving wireless access network and the… Read more »
