1.Indicate
where is our scope of work as a Cell Planner and Cell Optimizer.
2.Network planning work will follow
GSM network which progress in cyclic mode
The
macro view of GSM network planning is divided into 2 parts – Planning and
Optimization. It is a cyclic action
throughout the network expansion.
The
micro view of GSM network planning involved the planning work. It involves at
the pre-installation phase.
Steps
of GSM Network planning
The
left oval shape depict the work done in the initial planning and site
survey. Data collected in the left oval
shape is input into the middle oval shape.
Using the 3-D digital map as the basis, the middle oval provide 5
outputs.
The
outputs of the middle oval shape confirm the configurations for our right oval
shape’s design.
Work
involved in GSM Network planning
-Planning working contain
Planning
working contain：BTS
distribution、channel
allocation、cell
parameter planning。It is important to provide a full
design to construct network. This plan
may differ from the as-built.
1)The
location of BTS.
2)The
channel distribution.
3)Example
of cell parameter planning/BSC Network features --- Cell load sharing, Double
BA list and etc
…..
Joke
: What is meant by “ as built “.
Key
points in planning
• Provide a good coverage
prediction.
•Influence of site distribution to
network coverage and capacity.
•network long-term development and
on the whole planning.
Interference
from all kinds of sources ( building, Environmental, co-channel, adjacent
channel and etc ) has make the nominal cell planning
difficult.
During
the engineering design, the above interferences have to be taken into account
carefully.
As
the network capacity increase, the limited allocated number of frequencies is a
challenge for cell planning and cell optimization engineer.
The
network capital investment is an important consideration.
