5. • 距離・消費電力・通信速度のトレードオフ • 距離を伸ばす ⇒ 消費電力を上げる・通信速度を下げる • 消費電力を下げる ⇒ 通信速度を下げる・距離を短くする • 通信速度を上げる ⇒ 距離を短くする・消費電力を上げる • 全てに優れた通信規格は存在しない • アプリケーションの要件と実環境に合わせて選択 IoT向けのコネクティビティ
6. • 距離・消費電力・通信速度のトレードオフ • 距離を伸ばす ⇒ 消費電力を上げる・通信速度を下げる • 消費電力を下げる ⇒ 通信速度を下げる・距離を短くする • 通信速度を上げる ⇒ 距離を短くする・消費電力を上げる • 低消費電力ながら、冗長性と狭帯域により、長距離通信 • 長距離通信により、公衆回線網が成立 • 通信速度を下げることで、低消費電力の公衆回線網を実現 Sigfoxの特徴
7. Sigfoxの特徴 通信速度 上り（デバイス ⇒ クラウド）: 12 Byte（最大140回／日） 下り（クラウド ⇒ デバイス）: 8 Byte （最大4回／日） ➢ 通信速度が低い ➢ 通信が非対称 非対称な物理NWが前提、 IP通信をサポートしない （プラットフォームが仲介し、IP通信を実現） デバイスの低消費電力・低コスト化に貢献 想定される用途：大量のデバイスをばらまいてデータ収集 通信技術の制約に合わせたシステム設計が重要

36. 36 How are some of these Massive IoT use-cases thriving?
37. NCU Space Hotaru designed by UnaBiz Smart Gas Metering Nicigas is a gas supplier in Japan who wants to digitalise their gas consumption data collection. The Challenge Increase productivity with a 40% savings on distribution costs Delivery route optimisation Real-time billing Network Control Unit Space Hotaru is bringing these meters online: ✔ A full bespoke device created by UnaBiz ODM services ✔ Cost effective & scalable supply chain ✔ Optimised battery life leading to a TCO that is 4X better than other technologies ✔ Secure data transfer Solution • Offline LPG gas meters are costly to read manually • Lack of manpower in Japan The Results Efficient cash & inventory management Enhanced feature (to turn valve on/ off remotely) Utilities Japan
38. Belgium Smart Water Metering Water-link is a Belgian water utility supplying 640,000 residents across 190,000 households in Antwerp with a focus on customer service providing reliable water supply in the easiest way possible. The Challenge Increased billed water usage by 2% Detected 4,000 leaks and 375 backflow incidents Reduced water consumption for 18% of customers Smart meters and smart valves that communicate over Belgium’s 0G Network powered by Sigfox: • Daily meter readings • Remotely turn on and off water • Leak and reverse-flow detection • Restrict supply in response to non- payment of bills or general water scarcity caused by long periods of drought. Solution It was challenge for water-link to get accurate and timely data on water consumption when meters are read manually, and to detect water loss through leakage and fraud. The Results Real-time online access to consumption data for all residential customers Utilities
39. DHL is a global logistics company that deals with supply chain management that wishes to improve their inventory management The Challenge Improved customer satisfaction Reduce loss rate of Roll Cages Solution • Handling of their Roll Cages can cost up to 10x of their $300 cost throughout their lifespan • Inefficient data on the demand & supply of the cages increases costs and causes revenue loss • Untracked cages sometimes results in loss of parcels and delay in deliveries The Results Improved inventory management & better asset utilisation ✔ A powerful tracking device with ultra long battery life ✔ Low infrastructure costs and speedy set up within 1 day ✔ Collects data to deliver assets efficiently reducing costs ✔ Reliable tracker that does not need to connect to WiFi to track location (sniffs surrounding WiFi SSID instead) Smart Returnable Transport Packaging Supply Chain & Logistics Germany
40. Australia & New Zealand Konvoy is a beer keg rental company struggling to keep tabs on the whereabouts of its fleet. The Challenge Optimise distribution route Reduce lost and stolen kegs Reduce to 3 kegs in circulation for every keg in use Tracking of kegs within Australia & New Zealand: ✔ 7 year battery life bespoke keg trackers ◦ Wi-Fi sniffing for geo-localisation ◦ Temperature sensor & accelerometer Solution • Keg fleet not utilised to its full potential a.k.a. ‘Lazy Kegs’ • Loss of ~5 - 10% of kegs each year • CAP-EX issue - For every keg filled, 3 more are needed: 1 in-market, 1 in the warehouse, and 1 in storage. Total 4 in circulation. The Results Smart Returnable Transport Packaging Supply Chain & Logistics
41. Cold Chain Monitoring Loca Service is a leading refrigerated furniture rental company in France who needs to monitor their refrigerators' temperature and energy consumption. The Challenge Decreased Food Wastage Lower CAPEX & less operational disruption Real-time data improving management of assets A cost-efficient, low-power industrial-grade tracker with a temperature sensor that lasts for at least 2 years allows timely intervention of anomalies while adhering to HACCP standards. Solution • Manual reading are subjected to human error, not cost-efficient and labour intensive • Readings cannot be done when retail shops are close • Improper temperature conditions can lead to food poisoning The Results Supply Chain & Logistics France
42. Australia & Singapore The Challenge • Creates visibility into air quality across all indoor spaces • Capture CO2 levels in real-time, 24/7 • Utility data allows Operations team to plan indoor capacity, and regular ventilation • Enhancing productivity and end-user experience Solution • No data collection • Manpower intensive • Expensive The Results Smart Facilities Management (IAQ) Reduce the risks of transmission airborne diseases such as COVID-19 Real-time optimisation & better resource management Real-time data to ensure timely interventions Facilities & Building Management
43. Security Alarm Backup Connecting over 5.1M Devices Verisure is the leading provider of professionally monitored security solutions in Europe with presence in 16 countries. The Challenge 100% protection against radio frequency interference. Customers can be assured that their alarms will go off, even if their telephone networks are down. An enhanced solution at zero cost to the customers, as a simple firmware update is all that is required Differentiating product feature against other security alarm systems Verisure integrates Sigfox 0G Network in its security system as a backup to GSM network when there are outages and jamming attempts. When interference or jamming is identified, the control panel sends an alert via Sigfox which prompts the security protocol from the Verisure central command station. Solution Independent GSM networks used by most security alarm systems are threatened by jamming devices which are cheap and easy to acquire, so burglars have easy access to them. The Results “Sigfox’s communications-jamming protection is very robust compared to GSM. The RF power required to jam Sigfox communication with conventional jammers is huge and far beyond the power capability of jammers available on the market,” said Christophe Fourtet, co-founder of Sigfox 0G technology. “The security service also stays connected in the event of a network or power outage thanks to connectivity with the Sigfox network.” - Qiara Security Spain
44. Stolen Vehicle Recovery COYOTE Secure is a solution which relies on IoT trackers to enable the recovery of stolen vehicles as quickly as possible. The Challenge Proven to recover 91% of stolen vehicles in less than 48 hours The COYOTE Secure tracker is autonomous and resistant to jamming, and hidden in customers’ vehicles. The autonomous tracker can operate for 4 years without maintenance and relies the low-power Sigfox 0G technology instead of a cellular, GPS or Bluetooth technologies, that are often rendered useless with jammers. Solution About 3.5 million vehicles are stolen every year worldwide, including 700,000 in Europe. One vehicle is stolen every four minutes in France, and the value of stolen vehicles is estimated to be around €1 billion. The Results Security France Coyote Secure customers pay a monthly subscription fee of 14.99€ or 179€ per year for the service.
45. Smart Agriculture Monitoring Sencrop is a Sigfox partner that measures data such as air temperature, humidity, rainfall, wind speed, pests in individual plots of agriculture. The Challenge Solution • Weather can be hard to predict and measure • Insufficient time for contingencies can cause damage to crop and revenue loss The Results ✔ A monitoring system that provide 24/7 data to farmers so that they can decide on the best course of action for handling their plots ✔ Additional data that is provided helps to prevent and mitigate diseases and blights, increasing harvest Real-time management of plots of agricultural crops Increased control over crop management Decrease in pest related crop incidents Smart Farm & Agriculture France
