Estimation of QoS Dynamics in the Wireless Networks

An important performance aspect of widespread networks is the quality of perceived conversational speech of voice calls and data services. Today these networks belong to 2-2.5 generation. Third generation (3G) networks were created only in the last decade. Currently 3G technologies are standardized. Equipment manufactures and network operators are in the process of deployment of 3G networks. Scientific institutions pay attention to 4G and generally to next-generation telecommunication networks. The QoS for individual network user is becoming the main question of nowadays research. In this paper we investigate the possibilities and means to create special purpose module for the evaluation of perceived service quality. It is presented that demand for such module can be justified since the quality perceived by individual users varies greatly. The paper also shows that QoS depends on user location, time, network load etc. The aim of the presented work is to find better relations between ISP and enduser from QoS point of view.
