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,
• 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.

Huawei to unveil 4.5G at its MBB Global Forum in Shanghai BY November-2014

Huawei is in preparation of strategic solution in order to bridge the gap between 4G & 5G and use it as a steppingstone to develop a own proposal for 5G Contender.

During the recent GSMA Middle East 360, Hauwei unveiled the summary of the proposed 4.5G development plan to attract regional players to commit for candidature in deploying the Huawei solution in widespread.

The term "4.5G" created a HUGE buzz, but with very small detail on technological aspects it is not clear enough to conclude the expected improvement on existing 4G/LTE solutions.

In summary, Huawei's aim for 4.5G to achieve....

>  10 Gbps
>  100K Subscribers within a km² coverage
>  To serve the evolution between 2016 to 2020

Also willl support...

>  D2D in addition to M2M
>  4K Video Quality
>  3D Video
>  Complete control/service layer in cloud architecture
