Novamint – Who we are

4

Telecoms & Verticals have their own Reality and Language

IoT: we connect Telecoms & Verticals

We connect them

5

Promoting 5G and IoT to Verticals & Companies (Smart City, Utilities, Transport

& Logistics, energy...)

Bringing vertical use cases and requirements @ 3GPP

Acceleration of NB-IoT and Prioritisation of power consumption features for

Release 15/Release 16 (RAN / RAN1 / RAN2)

Massive IoT market growing steadily

But far away from projections

No Swiss Army Knife

Strong demand but market still confused and expecting right solution

Billions of devices not addressed yet (Asset Tracking…)

Main barrier: no global standard ecosystem meeting verticals’ expectations.

Universal coverage, easy deployment and power savings are paramount.

Mesh & Satellite IoT are coming to complete existing solutions

Massive IoT - Trends

9

Emergence of Mesh / WSN – mostly proprietary using unlicensed ISM bands

Bluetooth – improving Mesh

Mesh/Multi Hop relays IoT: coverage & power consumption

➔ Metering➔ Asset Tracking➔ Industrial WSN

➔ Asset Tracking

➔ Asset Tracking

Common aspects:• Address coverage issue• Optimized Power consumption (10 times lower

power combined with adaptive multi hop relays)

BL5 + Atmosic (Low power radio + On Demand Wake Up)10 to 100 times lower power to support Mesh

10

Plethora of low satellite IoT in horizon

LEO constellations mostly

Connectivity in remote areas with limited terrestrial coverage

o Sea

o Mountains

o Maritime, rail, road corridors

o Rural / Deep rural

Mostly complementary to existing low power IoT technologies

Satellite IoT

11

Massive IoTIssues & Requirements

12

• “Blackspot” – no coverage for deep indoor meters (> 5%)

• Battery of Meters positioned at edge of the cell

(high level of Coverage enhancement - CE)

drastically reduced and not in line with

service requirements (3y instead of 15y - not sustainable).

• Must have requirement:

– Enhanced UE relays to provide extensive coverage & better energy efficiency

Key issues for metering

13

Key issues for containers

Challenges:

• All containers must provide their information and

optimize battery usage to maintain a maximum

duration of a life.

• Capability to connect & battery usage change all the

time (depending on its position when shipped for

example and previous usage)

Containers A, B, E & F cannot use WAN directly

Containers C & D better positioned for WAN communication

Containers C & D can be used as relay by A, B & E through

Container F (multi-hop) or with single hop to communicate

depending on their battery usage

Or

A B

CF

D

E

=> Requirement: Dynamic UE relaying and multi hop is the only solution to address both aspects

Massive IoT at 3GPP

16

Scope Release 17 for NB-IoT/LTE-M in discussion (decision in Dec 19)

Multi hop relays and Satellite currently considered

But many hurtles and topics not yet prioritized

o Massive IoT not hype anymore (NR light, Home IoT, Industrial IoT more attractive)

o Several players would like to slow down the process for massive IoT

o Lack of correlation between standards and market needs (if not initiated by vertical)

o Many Telecom players mostly motivated by R&D / IPR driven activities

o Gap between release process / existing deployments: no feedback on last releases hindering

motivation for next steps

o History of relay in 3GPP /Existing D2D not created with IoT in mind (Sidelink)

Massive IoT @3GPP

Demystifying Multi Hop relays / Satellite IoT 1/3

Multi Hop Relays Satellite

This is complex to integrate in 3GPP FALSETechnos exist

Can be supported on existing NB-IoT design

Solutions exist - Very limited specification

impacts (Ligado/Sequans, Mediatek...)

It will take time to integrate in 3GPP FALSEAchievable in one release

as not that complexAchievable in one release

as not that complex

Will increase the power consumption FALSE

Quite the opposite – can lower 10 times and more

power consumption(better than connectivity

protocol)

Same as Terrestrial with LEO

Better power consumption combined

with relays & aggregation

3GPP shall not look into this FALSE

This is the 5G promise to change towards a system approach rather than just

simple connectivity protocols

5G promiseOr proprietary solution

will emerge

18

Multi Hop Relays Satellite

This type of access will bypass the operators

FALSE

If integrated, the traffic will go always to the

cellular network(remember Wi-Fi)

Satellite as complement to terrestrial when cannot

access other way(remember Wi-Fi)

This type of access will bypass the operator

TRUE

If not integrated, proprietary solution will

not use cellular (Amazon…)

If not integrated, proprietary solution will

not use cellular as primary or at all

(Amazon…)

There is no urgency to do that FALSEIf not done now, will come by proprietary solution –

everyone will lose

If not done now, will come by proprietary solution –

everyone will lose

Will increase TCO FALSE

Better power consumption increase

duration of lifeNo specialized devices

If integrated in same chipset – volume will

create economy of scale

Demystifying Multi Hop relays / Satellite IoT 2/3

Multi Hop Relays Satellite

There is nothing for me as an operator FALSE

Will enhance cellular Help to better

dimension/optimize network access (example

containers)SIM card key role to play

in the security (SE)

Will complement terrestrial

Provide network access when not possible by

terrestrialSIM card will play a role in security and connection management (operator

models winning –policies…)

There is nothing for me if I have my private spectrum or high frequencies

FALSE

Will provide enhanced coverage in area which

couldn’t be reached (Indoor/deep indoor)

Will provide enhanced coverage in area which

couldn’t be reached (not covered by network)

Summary

21

Multi-Hop Relay & Satellite needed/mandatory – to complement cellular IoT for massive IoT

Main benefits: Coverage + Low power consumption

Standardization in 5G strong ecosystem is key for success

The right time is…now!

Achievable in a reasonable time frame

Only possible if verticals demand it

Be vocal – challenge all players in & beyond 3GPP (Operators, vendors, ETSI, GSMA…)

Key takeaways
