getSignalLevel

public int getSignalLevel()

Obtains the number of signal bars of the LTE network.

The number of signal bars ranges from 0 to 4 or from 0 to 5. A larger value indicates better signal quality. The maximum value (4 or 5 bars) is determined by the lower-layer configuration.

指定者:

getSignalLevel 在类中 SignalInformation

返回:

Returns the number of signal bars, which ranges from 0 to 4 or from 0 to 5.
