Pros & Cons
Be inspiring
Be respectful
3G Sector Split
Sector Overlap
The sector Overlap in Downlink
results in poor EcNo and CQI in the
null areas near the site.
Neighbor Optimization
The cell splitting from 3 to 6 cells
per site require higher number of
neighbor relations to be defined per
cell and require more precision.

Antenna Pattern
(Twin Beam vs 3 Sector Antenna 6500)
Loss of Coverage in
Bore Direction due
to 5 dB low gain
650 BW
Antenna
Null.
Improved coverage in side lobes
due to 5~7dB higher gain in the
Direction of Twin Beams
EcNo degradation in Main lobes due
Degraded EcNo
due to overlap area
of Twin beams
