Debated in Parliament on 17 Feb 2014.
Ms Lee Li Lian asked the Minister for Communications and Information in comparison with the nationwide outdoor signal service coverage survey conducted by IDA in September 2012 that is performed with an average of 524,875 signal strength sample readings for each cellular network (a) how many sample readings are taken for the latest coverage survey in 2013; and (b) what is the time interval between each sample reading.

Under IDA's 3G Quality of Service framework, the nation-wide outdoor service coverage is tested with a minimum sample of 100,000 test signal strength readings per month, per cellular network. When samples are taken, an average of three sample readings is collected every two seconds by the test equipment for each of the three cellular networks.
September 2012's 524,875 signal strength readings per cellular network were higher than the minimum sample of 100,000 test signal strength readings as it was the first time IDA was performing an audit to validate the mobile operators' performance after the standard was revised upwards in April 2012.
IDA has also stepped up the frequency for its collection of signal strength readings. It is now conducted on a monthly basis starting from Q2 2013. The total number of sample readings taken over the second and third quarters of 2013 was more than 800,000 per cellular network. The survey results for the fourth quarter of 2013 are currently being compiled.
