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

• “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

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)

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

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)

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…)
