  2. Market needs overview

  3. Markets overview • Water, Gas, Electric SUN • Smart City applications that would leverage SUN infrastructures • Environment sensors • Public lighting • Public watering • Traffic Monitoring

  4. Market needs for Water & Gas SUN • One transmission per day • on-request reading (few bytes only) • data logging (<256 Bytes data / 24h) • energy counter + alert flags (leak, tampering, backflow) • Spontaneous alerts • Typical radiated Tx power • 10mW up to 500mW • Up to 20 years autonomy • with a non rechargeable battery • battery size adapted to output power which impact cost

  5. Market needs for Elec SUN • C&I & Residential: x1 Tx per day typ • On-request readings • Profiles • Packet size typ small • Can be large for data logging • Spontaneous alarm/alert notification • Typical radiated Tx power • 10mW up to 500mW • Supply options • Continuously power devices for meters • Solar panel, rechargeable battery, backup battery for repeaters

  6. Smart City beyond meter vision Water Smart Gateway Provider Firewall Multi Utility Customer Display Unit Smart Access GSM Base Station Elec Gas Consumer Access Point

  7. Coronis/FTRDPreliminary Technical Proposal

  8. Sub-GHz wireless connectivity platform • To meet battery powered devices (water&gas meters, sensors) • Low amounts of data with low radio traffic • Ultra-low power management to reach multi-year operation • Long range (high link budget) for cost effective network infrastructure and long operating range in real world environments • To meet AC powered devices (elec meters, other sensors) • Low amounts of data with low radio traffic (typical) • Can be larger amounts of data with higher radio traffic • Long range (high link budget) for cost effective network infrastructure and long operating range in real world environments

  9. Sub-GHz wireless connectivity platform • To support reliable communications • Spread spectrum • To support programmable parameters • Data rate, carrier frequency, output power • To offer both fixed and walk-by monitoring capabilities • Walk-by for installation and maintenance • To be compliant with regulations over the world • NA, Europe, Asia, Japan • To be cost effective with reasonable ROI

  10. Wireless network capabilities • Star, tree, and mesh topology • Self-discovery services, self-organizing and self-healing algorithms • Prevent over-hearing • Reliable transmissions for robustness against interferers and jammers • Efficient medium access system for coexistence of co-located networks in the same area • Encrypted communications

  11. Fundamentals – RF features • Sub-GHz ISM license free bands 915MHz, 868MHz, 316-433MHz • 2 classes of features: low data rate & higher data rate • GFSK modulation • Fast FHSS spread spectrum for low data rate • Programmable output power (power savings) • QoS management (RSSI, energy counter, class of device, …) • Automatic Frequency Control (top performance over full lifespan) • Automatic Sensitivity Control (robust to interferences in noisy area) • Both asynchronous and synchronized network operation

  12. Fundamentals – RF features - Cont’d • 2 classes of data rate • Low data rate for water, gas, elec: ~20kbps // 50kHz BW • Higher data rate for controls: 100kbps or more // 300kHz BW or more • Highly sensitive receiver • -113dBm @ 20kbps • -103dBm @ 100kbps or more • Programmable output power • Low data rate: +14dBm/+27dBm for end-points & +27dBm/+30dBm for range extenders & AP • Higher data rate: up to +30dBm for end-points, range extenders and AP • High link budget • 127dB with +14dBm > 1km LOS @ -3dBi coil antennas • 140dB with +27dBm > 3-4km LOS @ -3dBi coil antennas • Radio range extender • Native repeater function in all devices (truly mesh with all devices) • All devices are Full Function Device while cost is similar to Reduced Function Device

  13. Fundamentals – Reliable Comms • Fast FHSS: Fast Frequency Hopping Spread Spectrum • Fast hopping every 2 bytes for low data rate • x16 channels in EU • x50 channels or less to comply with FCC15-247 regulation (power dependent) • FEC: Forward Error Correction : BCH(31,21) coding (1/3 redundancy) • Data interleaving + LSFR data scrambling (whitenning) • Maximize transmission success on the first attempt • Encryption if needed // application dependent (session layer 5)

  14. Fundamentals – Cont’d • Operating Mode • Rx, Standby Mode with programmable period (duty cycle) 1sec typ • Support pseudo-synchronized network (beacon every 90mn) • Push mode with TDMA management to limit overhearing • CSMA-CA • Tx, Rx at any time from any device (alert notification) • Data logging • Power Consumption • Target of 15µA operating current based on 1s period (duty cycle)

  15. Real world deployment • Over 3 million devices deployed around the world based on similar features have given field-proven confidence • 60,000 points in France (water) • 50,000 points in Europe (water) • 100,000 points in China (gas) • 60,000 points in Balkans (water & gas) • 50,000 points in the USA water market (installation on-going) • 5,000 points in Spain (gas) • 10,000 points in Europe for lab temperature tracking • Open standard initiative is up and running • IEEE 802.15.4g would be a positive step
