Coverage target – Coverage area of each phase according to the roll out

strategy.

– Area type information such as Dense Urban, Urban, Rural, etc.

Coverage availability – Seamless coverage service.

– Indoor coverage consideration.

– Area coverage probability.

AMR 12.2K VP 64K PS 128K PS 384K

Coverage Requirements Collections

Which service to be selected as continuous service?

Continuous Service Dense Urban

Voice 450m

VP 380m

PS128 410m

PS384 280m

HSDPA 500kbps at cell edge 400m

HSUPA 150kbps at cell edge 380m

– PS384 will cause to many new sites to provide continuous coverage.

– VP can perfect meets both voice and HSPA PS coverage requirement.

– HSPA is suggested to be launched in all sites.

--- to obtain the average cell throughput

--- based on HSDPA simulation result

--- the maximum data rate is limited by the available

power, available codes resource and UE capacity

--- higher cell target load can be available for HSDPA

apart from that of R99 HSUPA will use the spare load apart from

that of R99, HS-DPCCH and A-DCH in uplink

--- based on HSUPA simulation result ;

--- the maximum data rate determined by the
