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.
