Notice

If consider HSPA+ evolution, better to use U5.0MHz solution;

Continuous coverage(GSM 4*3) supported;
Suggest to deploy in rural area;
Continuous coverage supported with multi RRU sharing one cell
feature;
 No gain from evolving to HSPA+;


No GSM continuous coverage;
compared to U4.2MHz, U3.8 can increase the GSM 20% coverage
 No gain from evolving to HSPA+;


<5M
No Refarming

Because UE TX BW is 5MHz, can’t deploy UMTS network

Increase UMTS
Bandwidth (+)
Description:
 GSM spectrum can be dynamically shared to
UMTS according to the traffic load or operators’
strategies.
 Site level spectrum switching.
 The shared spectrum can be 4.2M/ 4.6M/ 5M
according to UMTS carrier’s requirement.
Benefits:
 Lower the cost of spectrum refarming
 Refarming based on SDR
 Refarming based on hours
 Increase MBB throughput
5MHz of UMTS Shared BW can bring 50% throughput gain
2.0MHz Central Frequency point separation between
GSM and UMTS mode(UMTS)– RAN13.0
Driver： Lacking of the frequency resources for UMTS refarming
UMTS3.8MHz refarming solution for 850/900MHz.
Saving more frequency for GSM.
Benefits:
• More frequency saving for heritage network.
• Higher throughput compared to GSM
HUAWEI TECHNOLOGIES CO., LTD.
Description:
Compared to 5MHz UMTS, UMTS3.8MHz can save
1.2MHz bandwidth used for GSM . The central
frequency gap is 2.0MHz.
Dependency:
• 900M MRRU V1/ V2/V3
• 900M MRFU V2/V3
• 850M MRRU V2

Challenges and Needs
 “Connect Australia” plan
• Compulsory data coverage for rural and remote area
• Unaffordable to deploy nationwide 3G network on 2.1GHz spectrum
 Lack of 900MHz spectrum
• Optus has only 8MHz spectrum
Solutions and Benefits
 Expanded to 98% population coverage
• G900(nationwide) + U2100 (Urban & Suburban) + U900(Rural).
• Rural area download rate speed up to 7.2Mbps.
 60% sites reduction compare with U2100
 4.2MHz for UMTS, 0.8Mhz saved

 GSM spectrum is limited, only 5Mhz band in 900Mhz is available.
Deploy U900 and G900 in 5Mhz band at
the same time
Develop rural 3G market with less competition, but low population

Operator’s strategy
•Competition Strategy:
Develop rural 3G market to arrest rural users.
•Step by step deployment strategy:
First step: 50 U900 sites was deployed as trial in 2010.
Second step: 700 U900 sites was deployed in large area after
successful trial in 2011.
Third step: in 2012, it’s planed to cover all the rural area
seamlessly
