Light Cluster description

Type of cluster : Urban

This cluster started with some sites down and the Sites Shake Down

not ready, the Preliminary works (Neighbour list Check, Parameters

Check) were not done by WFI Engineering group. The reason to start

the cluster under theses condition was due to the Schedule.

Sites/Sectors:

15 Sites/36 Sectors available for the First Pass.

18 Sites/42 Sectors available for Second Pass.

18 Sites/42 Sectors available for Third Pass.

21 Sites/51 Sectors planned.

Sites Indoor were not taken in to the count : Palais des Congress on

air, and 2 VLA

OUTSTANDING ACTIONS AND COMMENTS TO IMPROVE PERFORMANCE

RESULTS

Action Comment

New Sites

integration

Since we have 3 Macro sites as VLA, the Cluster still needs aditional sites

to improve overall coverage and Site dominance. As an example: Marseille

Grande Bastille, Marseille David and Le Cabot.

Nlist Optimization

working on the Neighbour list Optimization is a necessity since it is a trade

off between Overshooting and Coverage reduction

Overshooting

St Loup UMTS (Cluster H), Garibaldi (Cluster D), and Marseille ST Julien

(Cluster B) were overshooting in areas with missing sites or poor coverage.

Re design

Is recommended a special study for the following sites: Le Frioul (Is

overshooting everywhere) and Marseille La Cadenelle (the Configuration

should be changed from 2 sectors with 65 degrees beamwith antennas to

just one sector of 90 degrees Beamwith antenna.
