Bring the value of Smart-Grid to end-users with Long range / Low power radio communications Aleksander TRACZYK Head of Business Services at Enel France «Making Energy user smarter» Olivier HERSENT CEO at Actility
The IoT Graal : Ultra-long range bidirectional communication within ISM power limits Probability of Gaussian variable to exceed value x Bit error rate Received power Information rate (bit/s) For a given reception power: When D (bit/s) decreases, Pe also decreases
The problem with low bitrate Range increases with energy per information bit. At given RF power budget, long-range implies low bitrate For traditional modulation technologies, low bitrate means narrow spectrum A 30PPM quartz may deviate as much as 25kHz on a 868MHz frequency FSK connectivity becomes somewhat random below 20kbps!
Spread spectrum backgrounder (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
Spread spectrum backgrounder (2) Receiver : incoming signal is multiplied by the known pattern Chips +1/-1 «1» reference pattern High complexity (synchronisation, doppler ) Signal bits add up, noise bits cancel each other the information bit is recovered
Tests in dense city : Paris 14dBm (ISM regulation), 868MHz, from rooftop GSM site 2km indoor range at ground level!
