Debated in Parliament on 14 Apr 2014.
Ms Lee Li Lian asked the Minister for Communications and Information whether IDA uses technologically advanced and more accurate methods to audit mobile network traffic logs besides drive and walk tests and, if so, what are these methods.
The Member is incorrect in suggesting that the IDA audits mobile network traffic logs by using drive and walk tests. It is illogical to use network traffic logs to measure network coverage since by definition, network data logs can only measure performance within the network and cannot possibly measure coverage in an area if it is not covered by the network. Hence, to measure network coverage, IDA uses drive-walk-cycle tests. Measurements for call success rates and drop call rates are based on the operators' network traffic logs.
