NB-IoT: The Need for Scanner Based Testing

NB-IoT, (Narrow Band Internet of Things), also known as Cat NB1, is a standard for connecting “things” to the internet through the cellular network. This is a standard focused on machine to machine communications. The range of applications are vast, with key applications including asset tracking, intrusion detection, utility meter reporting, smart parking areas, and… Read more »

eBook: What you need to know about NB-IoT technology and testing

Cellular wide area network technologies, in particular for security and mission critical use cases and applications, require very high network reliability and availability where proper device testing and also network testing is a must to always ensure the essential quality of service.

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 »
