Not much attention

paid back then onto

LPWAN focus….

Hopefully since then

NB-IoT back-up!


Through the Lens of ITU’s IMT-2020 (5G)

LoRa™ would definitely fit into Usage

Scenarios of Massive MTC


Through the (Magnifying) Lens of 3GPP & ITU

Massive Internet of Things,

clearly borrow lot of features

from “Green Field” LPWAN

Pilars, thus resulting in

common Verticals.

Sharing some Directions of improvements

whilst ultimate targets might differ,

depending on Time-to-Market (TTM), and

Costs Trade-offs.

IoT LPWAN MUST maintain both a VERY

Low TCO, and fast Roll-out.

Through the lens of 3GPP & ITU:

initial enablers & Data Monetization..

Network slicing: offering dedicated virtual sub-networks,

each with different flavors tailored to each Vertical Market needs.

Green Field LPWAN can definitely benefit from both such common

understanding of additional Data Value/Monetization, and disruptive

enablers such as Network slicing….

Through the Lens of 3GPP TR 22.891 – Rel.14 – Feb.’16

– New Services & Markets Enablers

• Wide area sensor monitoring & event driven

alarms

• IoT Device Initialization

• Wearable Devices

• Multi-Access Network integration

• Network Slicing

• Context Awareness

• Content Caching (e.g. GW/FOTA)

• Device with variable data

• Domestic Home Monitoring

• Materials & inventory Mgt & Location

Tracking

• Enhanced Positioning

• Green Radio

• ….

Non-exhaustive list

Many identified services & enablers are of very high

interest to Green Field LPWAN, for current deployments

or for future releases.

Frequency Bands &

Spectrum usage…


5G will aggregate all bands

Higher Capacity & Massive Throughput Coverage, High mobility

reliability

The very foundations of 5G are tightly related with new

spectrum assets. Ultimate ‘full power’ 5G (Phase 2) will thus

depend on WRC-19.

Europe for now, is behind in terms of unlicensed bands availability…slowing

down disruptive alternative approaches & ecosystems


5G for All Spectrum Types

ASA: Authorized Shared Access LSA: Licensed Shared Access

Following FCC decision with 3.5GHz, any similar scenario

for other bands, for “Green Field” LPWAN?


Finding more appropriate spectrum….for ALL

Need for appropriate (Alternative) IoT LPWAN Spectrum:

- IoT LPWAN Service clearly identified & recognized

- Shared spectrum

- Unlicensed

- Sub-GHz - Rules of usage more appropriate (e.g. Duty cycle, Tx

Power,…)

Allow disruptive Innovation, sustainable investment, new

Stakeholders’ Landscape, New business Models, open

competition

AVOID LOCK-IN

5G Enablers…


5G Advanced Wireless Technologies

The Radio access part & technologies are the major differences from

“Green Field” LPWAN.


5G PHY Layer – Enablers…

F-OFDM

Source: Huawei

Current “Green Field” LPWAN do not plan any PHY Layer evolutions.

Besides, some of 5G PHY techniques are not appropriate (complexity,

power consumption, price, TTM) to systems only focused on IoT.

“One to Rule them All”

approach.

SCMA: Sparse Code Multiple Access / F-OFDM: Filtered OFDM


GeoFencing, GeoTargeting, GeoPositioning, Tracking…

Smart Cities

“Next generation high accuracy positioning

will require the level of accuracy less than

[1m] in more than [95%] of service area,

including indoor, outdoor and urban

environment. Specifically, network based

positioning in three-dimensional space

should be supported with accuracy from

[10 m] to [<1 m] at [80%] of occasions, and

better than [1 m] for indoor deployments

[2].”

3GPP TR 22.891

LoRa™ is sharing the same

understanding w.r.t (network)

positioning seen as disruptive

application for IoT…Now accuracy

requirements clearly differ.

End-to-end (E2E) « Green Field » IoT LPWAN architecture

Currently LoRaWAN™ does not specify

the Core Network Architecture.

Many stakeholders providing the Packet

Core (including IoT platform) are well

known & recognized actors, thus providing leading edge expertise and

technologies.

Some “Guidelines” are being drafted to

facilitate Roll-outs, together with APIs

specifications.


5G Flexible E2E Network Architecture

Many “Green Field” deployments have the advantage of lack of

constraints from existing IT…in a sense they could thus be perfect

playground to benefit from the latest advances (NFV/SDN/Slicing).


5G - Dynamic Creation of Tailored services

Source: Qualcomm

Within LoRa™ Alliance we believe COMPLEMENTARITY

and thus CONVERGENCE is the way-forward to take full

benefit from all systems.


5G - Radio Access Virtualization

Even though there is

no C-RAN in LoRa™,

end-points are not

associated with GWs.

Any GWs hearing the

Rx Packets forward

them directly to Core.

This is also a perfect

playground for

Infrastructure

Sharing.

Currently only 1

Downlink.

5G Networks will be deployed by a variety of entities

requiring many different

categories of products

to support their digital

For enabling IoT to

take-off massively, the

whole (value) chain

needs to be capable of

offering the best prices…since all layers

would ultimately add

their own costs.

Challenge of course is

to avoid a collapse of the value itself…

Chipsets & (certified) Modules costs

are Key, but bear in mind the costs

Wrap-up…


Wrap-Up

“Green Field” IoT LoRa™ Networks are definitely addressing similar use cases,

scenarios identified within the 5G Umbrella, with the name of “Massive IoT”. Within

the next 2-3 Years many innovations are coming in the Back-End…

Some of the investigations and enabling technologies driven by 5G enthusiasm

and promising global market will definitely also benefit “Green Field” IoT

LPWAN.

Indeed, LoRa™ Networks are “Cloud Friendly” and benefit from the latest

advances in that domain.

Since Most of the time, in the absence of existing legacy Network, this gives fresh

opportunity to design NEW efficient architecture fully tailored for IoT Needs, thus

offering cost competitive advantages.

Ultimately, it is truly believed in LoRa™ Alliance that COMPLEMENTARITY

with Cellular brings growth opportunities to both, and will be facilitated

thanks to new 5G Core technologies.
