1 Internet des Objets Réseaux d’accès Long Range
Yannick Delibie –

2 IoT – Long Range Access (RAN)
Univers fini applicable Desserte du domaine public (Smart Metering/Grid/City vs Smart Home) Réseaux privés virtuels industriels (EMS, process indus) Marchés cibles: Services à QoS Facturations (eau, gaz, elec), suivi qualitatif (alertes, performances énergétiques) pour les marchés régulés et contrôlés Optimisation des process industriels Modèle économique tendu Détecteur, alarme

3 IoT: Complex Radio Access Network
Radio Home Access network LAN RF-ISM, PLC, Wired WAN (PLMN...) Repeaters/router : complex network access – interoperability, supervision, network MTBF

4 IoT Long Range concept LAN RF ISM – Long Range WAN
Cost optimization : hardware, installation, supervision and maintenance Star network : reliable system (cost, MTBF...)

5 IoT – Long Range Access avantages
Tech Single hop: no repeater/booster star network: no complex/dynamic routing procedure, simple addressing plan low power 14dBm (25mw) vs GSM (2000mW), Wifi (100mW) Scalability management (optimised) €€ No License (ISM Band) Limited network infrastruture Scalability management (number of end point/station)

6 IoT – Long Range Access disadvantages
Tech No standard/Open specifications Scalability management (specific management) Radio capacity (shared ressource) €€ Network to deploy – site

7 IoT – Long Range Access - objections
Why is LoRa relevant ? Short Range Low Cost Low Energy Consumption Long Range Robustness Long Range Low Cost Low Energy Consumption Robustness FSK ISM Wifi Cellular Range Autonomy Low Cost Low Energy Consumption Long Range Robustness

8 IoT – Long Range Access - focus
Wide Area Network Coverage Up to 2 km (indoor) to 25 km (outdoor) (up to Bidirectionnal symetric communication ISM frequency band Error-tolerant and high performance radio Spread spectrum modulation TX Low power (14dBm) Adaptative link rate L1/2: MAC Security (AES128), identification(MAC ADDR), mobility/routing, PHY mngt (ADR)

9 IoT – Long Range Access – radio performances
Long Range Performances

10 IoT - long range access – THE scalabilty
Nb_EP/Station = F(data_rate, packet_size, TXRX_freq, nb_channel, duty_cycle) 30bps to 6kbps,dynamic Limit protocol overhead and allows fragmentation Application dependant Typical 8 Typical 1% for ISM868MHz E.g.: Utility water meter use case => meter/station
