GU 3.8M/4.2M/5M Refarming Policy for Operator Spectrum Bandwidth

Recommendation

>=7.4MHz

UMTS 5MHz or UMTS 4.2MHz

6.6MHz~7.2MHz

UMTS 4.2MHz

6MHz~6.4MHz

U3.8MHz

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+;

5MHz~5.8MHz

U3.8MHz

 

<5M

No Refarming



Because UE TX BW is 5MHz, can’t deploy UMTS network

10M Frequency bandwith GSM900 5M

GSM900 5M UMTS900 5M

Frequency Sharing Between GSM and UMTS

With Low GSM traffic (-)

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


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

“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
