5G - Long Tail Use cases

Post Link

Gateway Function - DeComposition

Transforming GW Function in NFV, helps to decompose the GW Layer's Control and User Plane. The aim is to make the User Plane to be handled by simple infra than a stringent mobility gateway node.

A CAPEX saving opportunity is always good to adopt.

Like to find whether it is a vendor specific initiative or is it part of any existing 3GPP / ongoing proposal ?

A detailed take on GW Decomposition....

The basic concept :-

Qualcomm's - 5G New Radio prototype Planning

• The 3GPP 5G NR study item has begun as part of Rel14 and will feed into Rel15.
• Sub-6 GHz spectrum bands
• OFDM-based 5G air interface
• Supports wide RF bandwidths over 100 MHz

Telco Cloud : Hardware - Trends

Will post the industry trends, available products like HP,Dell, E///'s HDS, Cisco's UCS

SK-Telecom is developing some of the Cloud Infra. They are deploying these solutions in their network. There can be some more improvised products on the way..lets wait and watch.

May be they have the intention to develop their own HW platform.

The need for this strategic step is explained in following picture in terms of the key requirements !!

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.
