Further, the course incorporates cybersecurity approaches from the ITU viewpoint, and security aspects of emerging cloud computing and Internet of Things (IoT).

In the telecommunications industry, price is no longer the sole factor in purchasing decisions. Service quality plays a key role to all stakeholders and, particularly, in achieving consumer satisfaction. The measurement of Quality of Service (QoS) and Quality of Experience (QoE) is, however, becoming increasingly complex to obtain as quality can be compromised by various factors along the value chain such as with the network infrastructure, the devices and/or applications a consumer is using and other factors influencing a consumer's experience.
