Micro operator driven 5G ecosystem for local service delivery

IEEE 5G-IoT Summit18th September 2017, Helsinki, Finland.

Introduction

Introduction

• Policy makers have recognized the importance of

widespread deployment and timely take-up of very high

capacity networks as the key enabler for digitalization.

• 5G will revolutionize the traditional mobile business

ecosystem to serve vertical sectors’ specific needs

connecting billions of devices.

• This development is based on local dense small cell

network deployments in specific high demand areas,

which will open the mobile market for new players.

‒ Small number of big mobile

network operators (MNOs)

dominate the mobile market

with equal service offerings

‒ Spectrum licenses are

auctioned for tens of years

with nation-wide coverage

obligations

‒ Market entry for new

players is high due to high

investment barrier

Today:

‒ Local service demand grows

in digitalization of different

verticals especially in

indoors

‒ There is growing need for

local indoor small cell

networks and spectrum

licenses

‒ Sharing economy allows

cost-efficient network scaling

according to demand

”Network as a Service”

Future:

Trends of change in mobile business ecosystem

‒ Existing regulation does

not support local operator

business

‒ Building of dense indoor

networks by all MNOs is

expensive => Who pays,

what are the incentives?

‒ There is a need for a new

mobile business ecosystem

with local players to speed

up digitalization

Challenges:

From outdoor macro cell deployments

From owning infrastructure

From a small number of nation-wide long-term spectrum licenses

To local indoor small cell networks

To buying required infrastructure as a service

To a larger number of sharing-based local spectrum licenses

To emergence of a large number of local micro operators

From a small number of dominant MNOs

Trends of change in network deployments


Micro operators enter mobile market

9/27/20176

• Micro operators deploy and operate local

small cell communication infrastructure

in specific areas and offer local context

related services and content to

complement existing MNOs’ offerings.

• Micro operators can serve MNOs’

customers (neutral host), own restricted

set of customers, or both.

Spectrum sharing solutions

Regulators have approved spectrum sharing

9/27/20178

• The US regulator FCC:n has introduced a three-

tier model in 3.55-3.70 GHz that enables market

entry for new players with local access rights.

for entrants

• In Europe the Licensed Shared Access (LSA) concept

was standardized and trialed in 2.3-2.4 GHz band to

enable local mobile network deployments and is

extended to 3.4-4.2 GHz bands.

• Spectrum sharing solutions are cricital in

making new spectrum available for mobile

communications while protecting inbumbents’

rights in the long term.


5G spectrum authorization models

Spectrum authorization in 5G

• Spectrum authorization decisions determining who is allowed to use 5G bands including rights and obligations will shape the entire future mobile market.

• Serving of vertical sectors’ tailored needs in specific high demand areas is based on local small cell network deployments in the higher frequency bands.

Who is allowed to deploy and operate 5G radio access networks?

All this in a fair and transparent way to promote competition and innovation.

10


Micro licensing for granting local access rights

• Micro licensing can open the mobile market for new entrants to

deploy and operate local 5G networks in a specific areas.

• Micro licensing exploits horizontal spectrum sharing by protecting

micro licensees from harmful interference in their license area.

Vertical spectrum sharing protects the potential incumbents.

11

Exclusive licensing:Small number of license holders,

long-term availability, high price,

wide coverage

=> Free from harmful interference

License-exempt:Anyone can access, no fee,

potentially a large and varying

number of users

=> No protection from interference

Micro licensing:Local access rights for a large

number of new entrants

Coordination with other licensees

=> Free from harmful interference

=> Efficient protection of incumbents

which makes spectrum available

Conclusion

• Spectrum authorization decisions shape the

5G mobile business ecosystem where

traditional stakeholder roles are changing.

• New local micro licensing models are needed

to allow entrant micro operators to deploy

local small cell networks to serve vertical

sectors’ needs and promote competition and

innovation in the market.
