Mobile Traffic Increase

ITU-R M.2290 is future spectrum requirements estimate for IMT

Data traffic increased rapidly from 2009 to 2011 in Korea

Expect 13-fold increase in 2020 compared with in 2011

Mobile traffic is rapidly increasing due to deployment of smart devices and development

of communications technology.

Prediction of mobile traffic in Korea: maximum 349,622 TB in 2020, 444,016 TB in 2023

2015 Secure 170 MHz

Bandwidth at least

(700 MHz / 1.8 GHz / 2.5-2.6 GHz)

2018 Secure 290 MHz

Korea Mobile Broadband Plan

Corresponding to rapid increase of mobile data traffic

Additional bands of

1 GHz bandwidth by 2023

Securing 1190 MHz band-

width including bands

already allocated (390 MHz )

IMT bands below 6 GHz

Additional IMT bands

below 6 GHz -> WRC-15 AI 1.1

above 6 GHz -> WRC-19 AI

Discussion on IMT band below 5 GHz (WRC-15 AI 1.1)

Sharing studies and evaluation of availability

Sufficient bandwidths: wider than 10 MHz bandwidth

Service coverage: national or local

Global harmonization: channeling arrangements

Coordination with neighboring countries: harmonized use to

reduce mutual interferences

Easy relocation/re-farming: available bands for relocation, clearing

schedule and expenses

Support 3600-3800 MHz and 1452-1492 MHz

9

IMT bands above 6 GHz

Future Works for IMT to solve:

Congested use of incumbent services below 6GHz

Heavy traffic in dense urban area (e.g., ‘hot-spot’)

Demands on maximized efficiency of data delivery

IMT in the bands above 6 GHz with advantages:

Wide contagious bandwidth

Development of semiconductor technology

Facilitation of multi-beamforming in higher frequency

Tolerable path loss within small cells

5G Vision

Mobile Bands in the RR on a primary basis in 6-100 GHz

Stage 1: Mobile bands in all Regions on a primary basis

Stage 2: by additional allocation or upgrade to primary service

Exclude bands for passive services (Earth Exploration Satellite service or Radio

astronomy)

Exclude Planned bands for satellite service

Preferably, bands with less operating stations

Wide contiguous bandwidths (at least 500㎒ bandwidth)

Korea supports:

27-29.5 GHz, 31.8 - 33.4 GHz, 37 - 42.5 GHz, 45.5 - 52.6 GHz (Exclusion of 50.2

– 50.4 GHz), 66 - 74 GHz

Criteria for candidate band above 6GHz

1/1.1/4.1.10 Frequency bands within the range 5 350 - 5 470 MHz

Korea proposed WRC-19 AI to APG15-5

“ To consider identification to IMT in the frequency range between 27 ㎓ and 74 ㎓ including possible additional allocations to mobile service on a primary

service in accordance with Resolution YYY (WRC-15)”

APT common Proposal

“to consider identification of frequency bands for IMT including possible

additional allocations to the mobile service on a primary basis in accordance with

Resolution [ASP-B10- IMT_ABOVE_6GHz] (WRC-15)”

Resolution [ASP-B10- IMT_ABOVE_6GHz] (WRC-15) “Studies on frequency-

related matters for IMT identification including possible additional allocations to

the mobile services on a primary basis in portion(s) of the frequency range

between 25.25 and 86 GHz for the future development of IMT for 2020 and

beyond”
