U900 can meet VNPT expectation?
Page 4
VNPT
Expectation
Coverage Improvement
U900MHz 2.5~3 times larger than UMTS 2.1GHz
TCO saving - TCO (UMTS 900MHz) is less than TCO (UMTS
2.1GHz) because 30%~50% sites can be save to
cover the same area compared with UMTS 2.1GHz
- Can reuse existing equipments
U900
U900 can satisfy VNPT expectation

Principles to deploy 3G in Thai Nguyen
Urban Area
U2100 to keep capacity
Rural and Sub-urban Area
U900 to improve coverage
Re-use existing equipment as much as possible

How to deploy?
Page 7
1 Frequency Planning
Planning for all 2G frequency, dedicate 5 MHz for U900
2 Deploy U900 in rural area
Improve coverage, reuse equipment
3 U2100 Re-planning
Move U2100 to urban area to expand the capacity
HUAWEI TECHNOLOGIES CO., LTD. Huawei Confidential
All Area ( G900 S221+ U900 S111)
Remain 5MHz for UMTS900 within all the province.
Keep 3.4MHz for GSM900. GSM can support S221.
In this case no need buffer zone any more.
During the implementation we need to evaluate existing GSM capacity and do GSM frequency planning
for the whole network.
Huawei will cooperate with VNPT finalize the U900 quantity based on real requirement.

Simulation Result: UMTS RSCP Comparison after deploy U900
After deploy U900, RSCP is much better than existing U2100 simulation result
Existing U2100 result
U2100&U900 after planning
1. Total 27 U2.1G NodeB
move to Urban
2. Deploy 161 U900 site in
Sub-urban & Rural
3. The site quantity for
reference only.

Summary for Thai Nguyen Province
Page 16
Choose U900 5MHz and GSM 3.4MHz, No Buffer zone solution.
U900 co-exist with existing G900, separate antenna solution.
Re-planning GSM to S221for whole Thai Nguyen province.
Reuse RF board ,cabinet and feeder from Hanoi project.
Reuse existing RNC/OMC hardware and expand software license.
Huawei will cooperate VNPT finalize U900 quantity based on VNPT requirement.
