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

Method:

G1800 Extension
Method:
G900, U900 & 2100 Joint Capacity plan
GU interworking solution UMTS multi-carrier solution
Method:
HR/AMR HR RF Hopping VAMOS UISS+IBCA ICC/EICC/SAIC
Sabafon have enough 900M bandwidth to do refarming, Huawei suggest to keep the
existing G900 site configuration and no need user migration.
G900 User Migration
Traffic to G1800 Traffic to UMTS G900 TFR solution
Transfer traffic from G900 to other bands to guarantee the G900 network quality
