GU850/900MHz Refarming is the Best Solution for MBB • Wide Coverage: UMTS 850/900MHz 2.5~3 times larger than UMTS 2.1GHz

Coverage

•

Indoor Coverage : UMTS 850/900MHz 10dB better than UMTS 2.1GHz

Capacity

• UMTS spectrum efficiency is much higher than GSM

TCO

• TCO (UMTS 850/900MHz) is less than TCO (UMTS 2.1GHz) • 30%~50% sites can be save to cover the same area compared with UMTS 2.1GHz

Evolution

• Release more 850/900MHz frequencies for U850/900 to improve the user experience

G900 User Migration

G900 User Migration Proposal Transfer traffic from G900 to other bands to guarantee the G900 network quality

Method:  G900&G1800 joint capacity plan  G1800 Extension

Traffic to G1800

Method:  G900, U900 & 2100 Joint Capacity plan  GU interworking solution  UMTS multi-carrier solution

Traffic to UMTS

Method:  HR/AMR HR  RF Hopping  VAMOS  UISS+IBCA  ICC/EICC/SAIC

G900 TFR solution

Sabafon have enough 900M bandwidth to do refarming, Huawei suggest to keep the existing G900 site configuration and no need user migration.
