F1 &F2 with 30 watts in each carrier
F1 &F2 support R99+HSPA
F1 support R99,F2 support HSPA
Coverage (pilot channel)
If pilot power is set 36dBm, then pilot coverage is same
Coverage (dedicated channel)
Capacity
if there is no power congestion, the capacity increase 48%
Throughput
Advantage
HSDPA throughout is better

60% sites are multi-carrier sites
Even use three carriers in very hot spots
Service assignment strategy
Performance of multi-carrier network
Typical IFHO KPI (e.g. voice handover success rate) is around 96% to 97%.
All other related KPIs (such as RRC connection success rate, HSDPA PDP activation success rate) have not degraded after adding second/third carriers
