4G Mobile Service Coverage for April to June 2018
In-Building Service Coverage
The indicator measures in-building service coverage for the 4G cellular mobile network. In-building service coverage measures the percentage of data points collected in a building from a 4G cellular mobile network that achieves a minimum signal strength of at least -109dBm. Service coverage is measured at randomly selected buildings and at publicly accessible areas within the tested buildings as a proxy for the coverage in the entire building to avoid disturbing residents. In order to better reflect end users' experience, IMDA uses mobile phones to collect the signal strength data points.
| M1 | Singtel Mobile | StarHub Mobile |
|---|---|---|
| IMDA’s Performance Survey Period - Q2 (April to June) 2018 No. of Buildings with 4G Service Coverage of >85% at a Signal Strength of -109dBm or better/ No. of Buildings Tested |
||
| 54/60 | 60/60 | 56/60 |
Note: The same sixty buildings were tested across the three mobile operators. The performance of each of the mobile operator varies for each of the building tested. End users' individual experience may differ due to different models of handset used, handset settings, number of users in the vicinity, etc.
Tunnel Service Coverage
This indicator measures the service coverage for the 4G cellular mobile network within road and MRT tunnels. Tunnel service coverage measures the percentage of data points collected in a tunnel from a 4G cellular mobile network that achieves a minimum signal strength of at least -109dBm. The tunnel areas surveyed by IMDA include all road and MRT tunnels in Singapore. In order to better reflect end users' experience, IMDA uses mobile phones to collect the signal strength data points.

| North East Line | 99.97% | 99.97% | 99.92% |
| North-South Line | 99.93% | 100% | 99.95% |
Note 1: For road and/or MRT tunnels without a published result, it means that the respective mobile operator has not completed its 4G service deployment at the particular road and/or MRT tunnel.
Note 2: End users’ individual experience may differ due to different models of handset used, handset settings, number of users in the vicinity, etc. The tunnel service coverage results are based on IMDA’s coverage performance surveys.
