The importance of a “QoS oriented” testing approach
The concept of “Quality of Service” is well known by Service Providers, Vendors and professionals, but very few understand its impact on the user experience. Referring to QoS is easy when this concept applies to a single network element or a Circuit Switched service, such as a Voice call under a GSM cellular network.
The concept of QoS impacts dramatically on all the latest generation networks, such as UMTS/HSPA+ and LTE/LTE-Advanced. Thanks to a QoS driven approach, these networks make an important leap forward evolving from generic access technologies to Next Generation Networks.
