M2M/IoT via satellite -
developments in ESA’s satellite telecommunications group
ETSI IoT/M2M Workshop 2016 featuring the Smart World 15-17 November 2016 [email protected]

What do we do?
1. We fund research and development in satcom via a program called ARTES (Advanced Research in Telecommunications Systems)
2. We issue tenders for long-term developments – we fund
100%
3. Industry can always submit a proposal for a mid-term development you see a market opportunity for – we co-fund 75 to 50%, you bring 25 to 50%
4. We fund developments or studies in ground segment, space segment, payload and system – including in-orbit validation
5. We build partnerships with operators to validate innovative technology, equipment and services in-orbit and on-ground

Why use satellite for M2M/IoT applications ?
1. For remote, highly mobile, highly dispersed of wide geographical areas (maritime, aero, railway, vehicular)
2. Address a massive number of devices simultaneously – e.g. for software updates or activities from deep-sleep mode, alarms ( Narrow band Point-to-Multipoint (nP2M) ETSI TR 103 102)
3. Stable and controlled QoS – not necessarily low latency 4. Increased control over the network and not dependent on
MVNO/MNO’s 5. Backup to terrestrial connectivity 6. Very predictable power-usage of the end-nodes 7. Very low-power transmissions required due to regulatory
constraints – i.e. less than some terrestrial solutions 8. Benefit from the integration with GNSS data transmission
applications 9. Benefit from already satellite connected platforms (e.g. maritime)

Satellite M2M/IoT future requirements
1. A number of initiatives to offer Machine-to-machine (M2M) or Internet-of-Things (IoT) communication services via small satellites
2. Recent workshop at ESTEC in June 2016
3. Issues a. Spectrum – where is some frequency band left with a reasonable
chance of successful coordination? b. Communication protocols to have millions of low-power units
accessing the satellite simultaneously c. Lack of standards – no interoperability – ETSI?
ESA UNCLASSIFIED – For Official Use
Advances in low-power & massive uncoordinated access – millions of UE’s…
1. Low Power UE (< 25 mW or 7dBm)
2. If you have an “eNB” with only 50 kHz bandwidth – 100.000 UE could send 20 bytes every hour – 1.000.000 (one million) UE could send a 2 bytes measurement, 4
times a day. – 100.000 UE could send a 140 bytes SMS every 4 hours
3. ETSI TS 102 721 4. With existing satellites in orbit

M2M satellite terminal – modular phone module – planned in 2017
• Satcom Module for modular phones
We think well suited in combination with M2M satellite telecom missions for niche markets

Makerspace for satellite M2M/IoT
1. A half-million € activity which is meant to scout (together with ESA) a large number small tasks to implement quick and dirty
proof of concepts in the field of satellite M2M/IoT
2. Implemented with a minimum amount of paperwork
3. Small tasks could be e.g. prototyping new concepts, organise a mini-challenge for most wearable satellite M2M/IoT device, best energy harvesting M2M/IoT terminal, complement an Kickstarter campaign, experiment with an in-orbit payload…. LTE-NB1 over satellite
4. All ideas related to satellite communication prototyping welcome!
5. For ham radio amateurs/hobbyists/academia/garage-companies/individuals/hackers/inventors/….

Other M2M/IoT projects we will initiate in 2017
1. Prototype for efficient satellite backhaul of remote LTE-M1/LTE-NB1 cells
2. Study on integration aspects of M2M/IoT satellite networks with the future core networks
3. Study on satellite specific security aspects of M2M/IoT
4. Satellite M2M technologies live demonstration – 500 k€ a. Evaluate M2M protocols using in-orbit satellites b. Modify/adapt terminals c. Test campaign with background traffic
5. Large-scale real-time live 5G integrated satellite-terrestrial network Proof-of-Concept that enables the satellite terrestrial convergence - 1500 k€

Conclusions
1. New developments allow M2M/IoT services over satellite for massive amounts of uncoordinated UE’s using very low power
2. Various parties are proposing new innovative systems for satellite based M2M/IoT – often based on smaller satellites
3. There is a lack of standardisation for low power satellite M2M (to be included in ETSI ERM TG28 LTN ??)
4. Integration of satellite and terrestrial may still need some work – need for larger trials
5. No specific oneM2M to satellite network interfaces yet being considered
6. ESA is prepared to fund and co-fund any development in the satellite M2M domain
