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

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
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
