Urban M2M applications • Actual "Urban M2M applications" already do exist, a few examples are • Air quality and soil monitoring • Traffic & parking monitoring • Container track and trace • The backend connectivity is assured via the cellular network (GSM/GPRS/EDGE) or landline • Clearly sub-optimal (costly, power hungry) • Waste of precious resources (SIM card, phone number..) • Not able to handle a huge increase of devices • But there isn't any valid alternative for the moment • Despite all these drawbacks, applications do exist and demand is growing • Do we need a dedicated network for those M2M applications?
Services, soft & applications , , End User Urban WSN management - M2M Telecom Carrier Carrier infrastructure network Urban WSN - Sensor , actuator , meter Urban services and M2M applications • Actual market: • Small • Specifically designed for a given application • Why a Urban WSN ? • Leverage the network (WSN concentrator and WSN backbone) • Share some higher level tools (like application framework for ex.)
Some possible services A tool for a better City For better City management Urban infrastructure ( public lighting, watering) Water, gas metering Waste management Noise and pollution Monitoring Car traffic analysis Citizen information Monitor and analyze water and electricity consumptions Compare with citywide statistical data Better information on transport, congestion and pollution
A standardized utility network for carrier applications • Standardization ensures WSN infrastructure longevity • Standardization creates multi-sourcing opportunities to keep cost low • Standardization enables compatibility & interoperability for the adopter community • Best way to get a field proven technology with millions of devices installed worldwide

Wireless sensor network technology & backgroundWavenis Wireless Technology
Physical Layer : Wavenis • A wireless connectivity platform optimized for applications that: • Manage only low amounts of data with low radio traffic • Require ultra-low-power management to reach multi-year operation in battery-powered devices • Require a high link budget to attain acceptable/long operating range in real world environments • It supports a wide variety of application protocols • It provides both fixed and mobile monitoring capabilities
Trade-off Low Cost Ultra-Low-Power Wavenis technology Reliability Long Range
Fundamentals of Wavenis AdministrationTool Customer’s Data Center GPRSGSMCellular InternetEthernetWi-Fi Concentrator Repeater End-Point In-home Display • Network features • Star, Tree & Mesh topologies • Self-organizing • Self-healing
Fundamentals of Wavenis – Cont’d • RF features • Sub-GHz ISM licence free bands 868MHz, 915MHz, 433MHz • GFSK modulation • FHSS spread spectrum @ 50kHz bandwidth channels • Programmable output power (power savings) • QoS management (RSSI, energy counter, class of device, …) • Automatic Frequency Control (top performance over full lifespan) • Automatic Sensitivity Control (avoid false wake-up in noisy area)
Fundamentals of Wavenis – Cont’d • Long range (high link budget) • Low data rate // 4,8kbps min < 19,2kbps typical < 100kbps max • Highly sensitive receiver // -113dBm @ 19,2kbps • Programmable output power // +14dBm (25mW), +27dBm (500mW) • Radio range extender // native repeater function in all devices • Link budget // 127dB with 25mW >1km LOS & -3dBi coil antennas
Fundamentals of Wavenis – Cont’d • Reliable Transmissions • FHSS: Frequency Hopping Spread Spectrum • Fast hopping: every 2 bytes • Min x16 hops (out of x50 channels) • FEC: Forward Error Correction : BCH(31,21) coding with 1/3 redundancy • Data interleaving => Maximize transmission success on the first attempt • Flexibility • The Wavenis Specification today defines the wireless connectivity platform only • Any application can run over the Wavenis connectivity stack
Real world deployment • Over 3 million Wavenis-enabled devices are deployed around the world • Some Large scale deployments • 60,000 points in France (SAUR) • 50,000 points in France (VEOLIA) • 50,000 points in China (HowDeep, gas) • 60,000 points in Balkans (CMC, water & gas) • 50,000 points in the USA water market • 5,000 points in Spain (Gas Natural, gas) • 10,000 points in EU for lab temperature tracking
