GSM Frequency Analysis Application
Scenarios
Scenarios of GSM frequency analysis are as follows:
Perform frequency optimization for some key cells after frequency planning on
the entire network.
Perform frequency optimization for cells with poor network quality or VIP cells.
Select frequencies for capacity expansion of cells.
Output the interference matrix to be used by other tools for frequency analysis.

Subtract the level of the
neighboring cell from the
level of the service cell. Ifthe obtained value is
smaller than 12 dB, and
they are configured as

Meanings of values in the frequency
separation rule table are as follows:
Difference values of absolute frequencynumbers of two frequencies must be
greater than the set value:
0: Difference value of absolute frequencynumbers must be greater than or equal to
0 (that is, there is no restriction).
1: Difference value of absolute frequency
numbers must be greater than or equal to
1 (that is, the cells must not be configured
as intra-frequency cells).
2: Difference value of absolute frequency
numbers must be greater than or equal to
2 (that is, the cells must not be configured
as intra-frequency or inter-cell cells).

Tip: The function is used together with the neighboring cell, MR,
frequency, and uplink interference analysis functions to improve
the efficiency of solving subscribers' complaints.
Measurement information before call release:
1. For complaints of common subscribers, the Nastar provides the function of analyzing a few measurement reports before call release.For complaints of VIP subscribers, the Nastar provides the measurement analysis of the entire call process.
2. The measurement information analysis function provides two analysis methods, namely, measurement information table and measurement
information trend chart.
