Neighboring Cell Analysis Principle
• The overall score of a neighboring cell is calculated by Ec/Io and the appearance
times of the neighboring cell (Y axis)
• Neighboring cell is sorted in descending order of the overall score (X axis)
• Missing neighboring cell: recommended priority <recommended number of
neighboring cells
• Redundant neighboring cell: recommended priority >recommended number of
neighboring cells

Nastar
Based on the MR data, ICDM (inter
cell dependency matrix) is
calculated, and is applied in
frequency optimization.
Accurate, High efficiency, Low cost
ICDM:
• Co-frequency ICDM
• Adj-frequency ICDM
Frequency Table :
• Whether to meet the spacing rules
• Interference to the VIP cells
Interference Chart:
Directly display interference of each frequency on the histogram and line chart

Remote Uplink Interference
Analysis by Nastar
Traditional Method
Nastar
Manual test site by site
The time and the type of interference could not be identified
Remote analysis is based on RTWP data
The time and the type of interference are identified according to RTWP trend chart and main-diversity difference chart
Accurate, Low cost, Low difficulty

Background:• Brunei is covered with dense vegetation and has a large
population, which results in great difficulty in radio
coverage.
• The investment is limited. The number of sites is
insufficient. With poor coverage, the network also
contains a great number of missing neighboring cells.
The call drop rate ranges from 2% to 3%, which is quite
high.
• The operators in Brunei have little wireless network
operation experience. They are also lack of operation
and maintenance engineers.
After the Nastar is used:• The configuration of co-channel frequency neighboring
cells is checked to one hundred percent. Therefore, the
problem of missing neighboring cell configuration
solved.
• The problem of high call drop rate is solved while the
coverage rate and coverage quality are ensured. All the
KPIs reach the requirements.
• The entire optimization requires three engineers
working a day. Compared with the traditional
optimization method, the efficiency is improved 20
times.
