5G Vision: key e2e operator requirements

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.

5G Technology Candidate :- Access Optimization

View S.Sunil Kumar's profile on LinkedIn

Traditional concept of having a Uplink / Downlink channels irrespective of TDD/FDD mode is the major  point that defines how the spectrum is well utilised and also the ability for further aggregation.

3GPP RAT development team is working on existing Radio Network Coding to enhance the way of using the Channel without decoupling Logically (TDD) or band wise (FDD).

With this improvement, the Career Aggregation will be simpler than before and bandwidth can be provided on demand depending upon the availability with simple access procedure across different bands/RATs.

5G Technology Objectives

View S.Sunil Kumar's profile on LinkedIn


BIG DATA analysis has proven that it can add value to existing business and provide innovative solutions. This leads to revolutionize the business ideas across globe.

It requires a natural partner in terms of broadband connectivity on the fly to help business community in thriving the world economy. ICT Community's main aim to serve this requirement and  empower the growing demands of rural communities. This relationship outlines required objectives for 5G Technologies as stated below.


  • 5G Networks will be able to serve 100 billion connections.
  • 10 Gb/s will be the data rate per user,
  • 5G Netwoks will have new RAT + LTE+LTE-A+WiFi+GSM+HSPA.
  • 5G Netowkrs may serve 3 folds of world population in M2M connections.
