4G Measurement Survey Results for October to December 2018

4G Mobile Service Coverage for October to December 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.
