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,
• Technology MIMO 4×4.

5G Trials - KT Korea and Ericsson

• 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.
