Why Refarming? Demands from Data Growth
Data services offset the falls of voice revenue and becomes the key driver to growth
• Voice ARPU falls in 4 countries
Coverage Requirement
• No 3G service in rural area• Coverage gap between 2.1GHz and 900MHz
ServiceRequirement
• Poor or No data service in rural area (inc. fixed data access)
CapacityRequirement
• 2.1GHz spectrum insufficient for 3G capacity
CostRequirement
• TCO (UMTS 900MHz) << TCO (UMTS 2.1GHz)
EvolutionRequirement
• partial 900MHz frequencies spared as GSM subscribers moving to UMTS gradually
• UMTS grows as GSM turns down

Refarming Get Better Network on Lower Cost
Cell Coverage Comparison
Radio planning U900 vs. U2100: about 6dB better link budget in U900, Cell Coverage of U900 2.5~3 times larger than U2100
Radio planning U900 vs. G900: Link budget +6-9dB, Better receiver sensitivity Capacity planning: Co-site for higher capacity sharing, 50% fewer sites with U900 than U2100

Flexible Huawei UMTS Refarming Solution
Sandwich frequency solution Sandwich allocation flexibly puts U900 carrier i
nto the proper spectrum location based on the UU solution and interference consideration with other operators.
Edge allocation solution Edge allocation solution has lower frequency u
tilization since the more frequency guard bandwidth shall be reserved to avoid the risk.
Min. frequency gap (f1): 2.2MHz separation Min. frequency gap (f2): 2.6MHz between
UMTS900 and the GSM900 of neighbour operator
Sandwich frequency solution is preferred

Scenarios GSM 1800M is available and continuously covered;
GSM 1800M has rich frequency;
G900 and G1800 are deployed with Co-site
Migration Strategy Active HR, raise its proportion configured up to
50%~70% Transfer traffic from G900 to G1800 by add site configuration

Better cell handover

Traffic sharing Strategy Camp on G1800 and G900 randomly in the idle state,
UE prefers to make the cell selection to G1800. Allow intra-frequency better cell handover; Load handover is performed according to the traffic
HUAWEI Confidential Page 20
2G traffic migration Strategy-2 ( G900->U900)
Migration Strategy Active automatically the U900 service for all the existing 2G users Dual-mode terminal and 3G rate policies appeal to the transferred 2G user Voice traffic shared on UMTS900 shall be dimensioned, and the experience shall be good. Transfer traffic from G900 to UMTS900 with the above preconditions.
Traffic sharing Strategy Terminal camp on UMTS as long as it support G/U dual-mode Dual-mode UE camp on GSM in no UMTS coverage area Voice calls remain in individual RAT cells PS service on dual-mode UE shall perform Cell Reselection or HO if it enter into UMTS coverage area

Proposal for buffer zone plan:Buffer zone distance is commonly 2~3 layer sites or the distance of twice cell diameter,
RF optimization or obstructed topography will deduce the size of buffer zone
The co-frequency interference signal received in the A or C shall below -110dBm

3dB insertion loss (DL/UL) 30% coverage reduced Not support RET
New sites needed to retain existing GSM coverage
Advantage of SASU
negligible loss on UL < 0.6 dB loss on DL Support RET function (with 10dB Gain)
Negligible Impacts to GSM

Antenna Solution Summary
Solution Advantages Disadvantages
Independent antennaEasy to implement RF optimization
respectively.much additional cost needed
Co-antenna with SASU Save the installation space and cost for
antenna and feeder
1) 3G and 2G system can not adjust the down tilt angle and
azimuth independently;
2) downlink increase less than 0.6dB loss.
Co-antenna with 3dB
combiner
Save the installation space and cost for
antenna and feeder
1) 3G and 2G system can not adjust the down tilt angle and
azimuth independently;
2) downlink increase more than 3 dB loss.
Co-antenna
with GU mRRU/mRFU
1) save the space and cost of antennas
and feeders;
2) No insertion loss;
3) Easy RF tuning for 2G/3G co-coverage
objectives;
3G and 2G system can not adjust the down tilt angle and azimuth
independently;

Mobile strategyIn idle state, bidirectional reselection between U900
and U2100, Bidirectional handover based on coverage from UMTS2100 to UMTS900 is recommended
In only U2100 F0,F1,or F2 overlapped coverage area, UE camp on UMTS2100 F0 as preference.
U2100 F1 and F2 have higher priority for HSPA service than U2100 F0, and such service accessing to F0 will DRD to F1,F2.
