Lets cover the concept, use cases, requirements - Technology/Elements..etc...
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 :-
- 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,
- Technology MIMO 4×4.
- Tested speed 25.3 Gbps
- Millimeter Wave (mmWave) with Multi-user, Multiple Input, Multiple Output (Mu-MIMO)
- It is over 80 times faster than the current LTE-A.
- KT is aiming to provide 5G trial services for the PyeongChang 2018 Winter Olympics.
