IMDA just published it’s quarterly report of QoS for mobile operator in Singapore for Jan to Mar 2024.
IMDA’s 4G Service QoS framework, mobile operators are required to achieve Nationwide Outdoor Service Coverage of > 99%. In order to better measure the end users’ experience*, IMDA uses mobile phones to collect the signal strength data points.
The four MNOs all performed above the 99% level mark.
As for building coverage, the same sixty buildings (not listed) were tested across the four mobile operators. The performance of each of the mobile operator varies for each of the building tested. All passed. IMDA’s 4G QoS framework, mobile operators are required to achieve a service coverage of > 85% per building.
As for tunnels and MRT, Tunnel service coverage measures the percentage of data points collected in a tunnel from a 4G cellular mobile network that achieve a minimum signal strength of at least -109dBm. The tunnel areas surveyed by IMDA include all road and MRT tunnels in Singapore. Under IMDA’s 4G Service QoS framework, mobile operators are required to achieve a service coverage of > 99% for all road and MRT tunnels.
All 4 telcos passed all MRT and road tunnels.
