Making GSM Base Station Measurements
Making the Phase and Frequency Error Measurement
a receiver to correctly demodulate, especially in marginal signal
conditions. This ultimately affects range.
Occasionally, a Phase and Frequency Error measurement may fail the

beginning. This could indicate a problem with the transmitter power
ramp or some undesirable interaction between the modulator and
power amplifier.
