Editing Mobile QoS (section)

==Factors affecting QoS==
Many factors affect the quality of service of a mobile network.<ref name=Miao/> It is correct to look at QoS mainly from the customer's point of view, that is, QoS as judged by the user. There are standard metrics of QoS to the user that can be measured to rate the QoS. These metrics are: the '''coverage''', '''accessibility''' (includes GoS), and the '''audio quality'''.<ref name="qos">{{Cite web |title= Quality of Service Indicators |work= GSM Mobile Networks - Quality of Service Survey (July 2002) |date= October 2002 |publisher= Autoridade Nacional de Comunicações |location= Portugal |url= http://www.icp.pt/template12.jsp?categoryId=48949 |archive-url= http://arquivo.pt/wayback/20051120114948/http://www.icp.pt/template12.jsp?categoryId=48949 |url-status=dead |archive-date= 2005-11-20 |accessdate= October 14, 2011 }}</ref> In '''coverage''' the strength of the signal is measured using test equipment and this can be used to estimate the size of the cell. '''Accessibility''' is about determining the ability of the network to handle successful calls from mobile-to-fixed networks and from mobile-to-mobile networks. The '''audio quality''' considers monitoring a successful call for a period of time for the clarity of the communication channel. All these indicators are used by the telecommunications industry to rate the quality of service of a network.<ref name="qos" />
