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 the 47 routes and in the 20 HDB estates, an average of 221,160 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.

Notes:

Service activation and number of complaints are based on self-reporting results submitted by the service providers to IDA on a quarterly basis. Statistical reporting provided by the different service providers may differ.

1. Service activation time refers to the time taken between the receipt of the customer application from the dealer and the activation of the service. All service applications are to be activated < 4 working hours.
   
   
2. Figures are rounded up to 2 decimal places. Readings under "No. of Complaints Per 1000 Subscribers" will be rounded up to 3 decimal places
