IoT– Long Range Access (RAN) • 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 • Univers fini applicable • Desserte du domaine public (Smart Metering/Grid/City vs Smart Home) • Réseaux privés virtuels industriels (EMS, process indus)
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
IoT Long Range concept LAN RF ISM – Long Range WAN Costoptimization : hardware, installation, supervision and maintenance Star network : reliable system (cost, MTBF...)
IoT– Long Range Access avantages • Tech • Single hop: no repeater/booster • star network: no complex/dynamicroutingprocedure, 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)
IoT– Long Range Access disadvantages • Tech • No standard/Open specifications • Scalability management (specific management) • Radio capacity (shared ressource) • €€ • Network to deploy – site
IoT – Long Range Access - objections • Why is LoRa relevant ? Short Range Long Range FSK ISM Autonomy Wifi Cellular Low Cost Low Energy Consumption Long Range Robustness Range Low Cost Low Energy Consumption Long Range Robustness Low Cost Low Energy Consumption Long Range Robustness
IoT – Long Range Access - focus • Wide Area Network Coverage • Up to 2 km (indoor) to 25 km (outdoor) (up to -137dBm @300bps) • Bidirectionnalsymetriccommunication • 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)
IoT – Long Range Access – radio performances • Long Range Performances
IoT- long range access – THE scalabilty Nb_EP/Station = F(data_rate, packet_size, TXRX_freq, nb_channel, duty_cycle) 30bps to 6kbps,dynamic Limitprotocoloverhead and allows fragmentation Application dependant Typical 8 Typical 1% for ISM868MHz E.g.: Utility water meter use case => 16600 meter/station
