Making Things Smart ISN Conference Long Range Connectivity Networks for Sensors November 4 th 2014 1
Low-power RF : A new option for M2M M2M Conquers new domains! Mobile Broadband (Mobile, SIM Card) Low Power RF (Smart metering, Smart city ) c Fixed Broadband (Security, Confort, Safety ) 2
Need for Low Power, Long Range Connectivity Autonomy Traditional ISM (FSK)??? Wifi Cellular Range 3
A bit of theory Probability of Gaussian variable to exceed value x The IoT Graal : Ultra-long range bidirectional communication within ISM power limits Bit error rate Received power Information rate (bit/s) For a given reception power: When D (bit/s) decreases, Pe also decreases Low bitrate means longer range 4
The spread spectrum approach (1) Originally used for military communication, spread spectrum transceivers transmit a known pattern of bits for each information bit. «0» «01001011101001110101011101111011» «1» «10011011011010101111101101110111» RF spectrum is «spread» accordingly Channel becomes wide enough for a quartz receiver : symmetrical bidirectional communication becomes possible UNB Spread Spectrum 5
The spread spectrum approach (2) Receiver : incoming signal is multiplied by the known pattern Rx chips = spreading sequence chips + noise chips Chips +1/-1 «1» reference pattern Spreading sequence chips add up while noise chips cancel each other Information is recovered with negative SNR (-22dB)! High complexity (synchronization, Doppler effect ) 6
This brings new applications in Smart Grid/Building/City/ a unique network for low-power sensors and long range applications such as Smart Grid, Smart Building, Smart City and Smart Factory applications 7
Need for Standardization o The M2M market is taking off but is fragmented o Each industry vertical has its own set of protocols, authentication and security mechanisms o Economies of scale necessary for fast roll-out of M2M and Internet of things are difficult to achieve o The legacy world of sensors presents hardware embedded with specific applications o No model for developing incremental applications on existing sensors Business Application#1 Device Business Application#1 Business Application#2 Business Application #N Common application infrastructure Transport Network o Revenue models now shifting to supporting business decisions with M2M data intelligence Device Fast and Global standardization is a key enabler to ensure interoperable services and networks 8
What is ETSI M2M? o ETSI M2M defines a service capability layer on top of connectivity layers o It presents an API for application development based on REST principles M2M Applications ThingPark Cloud ThingPark OSS NMS ACS o ETSI M2M key assets include: o Standard API for messaging, FIFO storage, Access Control ThingPark Wireless Net GSC NSC o Standard Access to any REST interface o Standard interface to local M2M gateways o Standard and uniform resource designs for major automation protocols: ZigBee, WMBUS, KNX, ModBus LRC LRR Device Local Gateway (GSC) 9
