DSS - Dynamic Spectrum Sharing Related Articles

There are many negative comments on DSS, where some vendors are declaring it affects existing LTE and its performance a lot. In a way, yes, but there are solutions to optimize that. It requires some thought process in your network build. One Key Decision point will be, It supports smooth evolution from sub-3G bands/resources to 5G. Is there is any other method?

DSS - Dynamic Spectrum Sharing #5G & #4G, has its share of performance issues due to certain limitations in the underlying technologies. However, there are efforts to address them with some enhancements.

Lets cover the concept, use cases, requirements - Technology/Elements..etc...

Regular Updates @ Linkedin Post

5G Uses Cases :-

5G Requirements :-

5G System and Packet Core - Requirements

• A RAN technology agnostic packet core 

• Independent Changes and enhancements to one equipment/network domain s

• A decoupling of Hardware and Software functions of network elements in all network domains [ToC/NFV]

• Optimized Cost and effort, to achieve smoother upgrade path and leverage existing infrastructure

• Real-time and on demand network - SDN/NFV

• Flexible and cost efficient network operation

• Maximize utilization efficiency of available network resources (new/existing)

• Dynamic relocation of network resources depending on current and local needs, fully controlled by operator with automation

5G Key Technologies :-

5G RAN Evolution - Expected :-

5G RAN Evolution - by NOKIA :-

5G RAN Evolution - by Huawei:-

5G Trials - Megafon Russia with Huawei

• Huawei and prototype devices based on Qualcomm Snapdragon X16 LTE.
• The peak download speed during the test is 1.24 GB/s.
• Aggregation of 3 carriers: 20 + 20 MHz Band7 (2600 FDD)

and 20 MHz in Band 3 (1800 MHz, FDD),

• Modulation 256 QAM,
