Call Success Rate
This refers to the number of successful calls established over the total number of mobile call attempts.
Service Coverage (Street-Level)
The definition of service coverage in this case 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 132,615 samples of signal strength were obtained for each network. Samples of signal strength were taken at approximately 0.5-second intervals.
Voice Quality
This refers to the network's ability in achieving an acceptable level of voice quality using the Mean Opinion Score (MOS) measure and is a complementary indicator to the service coverage indicator.
Call Dropout
This refers to the unintended disconnection of the mobile calls by the network during a 100 second call holding period for each call.
