Quality of Service (QoS) Standards for 3G Public Cellular Mobile Telephone Services for Jan - Jun 2007

The definition of service coverage is based on signal strength. The availability of service coverage is therefore the ability of a network in achieving a minimum signal strength of -100dBm. Of the successful calls established by the mobile networks along expressways, major and secondary roads/ streets, an average of 254,449 samples of signal strength were obtained for each network.

This indicator measures the success of a call attempt. A successful call attempt is when the calling party gets a connection to the called party either through a ringing tone or an engaged tone. The call success rate shown below is based on an average of 547 call attempts per network.

This refers to the average File Transfer Protocol (FTP) download speed of 5MB file from a reference server.
