11 Private vs Public Network Private network individually managed networks Network deployed for single application purpose Public network Telecom/operator managed networks Connect multiple applications (multi-tenant) into a single network Consolidate fragmented wireless applications to improve ROI for entire market Private Network Public Network 11

12 First Public Network Deploying Country wide LoRa networks being deployed and evaluated in many countries around the world by major telecom companies Applications secured to guarantee ROI of network deployment 12

13 Target Applications: 2014 US Market Estimates SMART ENVIRONMENT & INDUSTRIAL Forest fires Air pollution Earthquake sensors Avalanche and flooding Heating and AC Equipment status Factory control 75M SMART METERING Electric Water Gas Infrastructure & production 450M SMART CITY Smart parking 200M Traffic sensors & control Street lighting Infrastructure monitoring Trash and waste containers Public events location services Advertising displays TRACKING Motor bikes Cars Bicycles Kids Pets 250M Insurance valuable assets Find My Stuff AGRICULTURE Irrigation control Environment sensing Animal tracking 25M Animal sensing ovulation, birth SECURITY/ SMART HOME Smoke detectors Security systems Smart appliances 250M Heating control / monitoring 13

14 LoRa Technology LoRa utilizes a spread spectrum based modulation Advantages Demodulate below noise floor 30dB better than FSK Better sensitivity than FSK (better Eb/No) More robust to interference, noise, and jamming Spreading codes orthogonal multiples signals can occupy same channel Tolerant to freq offsets (unlike DSSS) 14

15 LoRa Network Attributes Key Features 157 db link budget >15 km range Minimal infrastructure Concentrator with capacity >10 yrs battery lifetime RX - 10 ma, sleep <200 na Attribute/Benefit Long range Ease of deployment Long battery life Unlicensed spectrum Low infrastructure cost Low cost Low end-node cost A long range star architecture with high capacity Supports both mobile and fixed nodes Supports variable data rates and multi-channel simultaneously Complete solution with both end node (SX127x) and concentrator (SX1301) 15

16 LoRaMAC System/Security Long range star network (same architecture as cellular) Easy to deploy/maintain, reduces cost of infrastructure, optimizes battery lifetime Complete solutions for gateway and network server available from Semtech partners Large ecosystem of available applications and modules from market leaders 16

17 What is LoRaMAC Open source MAC protocol Developed by IBM, Semtech, Actility, and Microchip Different classes of nodes to optimize different application profiles End node source code distributed for free Microchip MPLABx and through ARM MBed End-node unique ID allows IPVx and 6LoWPAN systems Full AES encryption to end application server through network Includes provisioning, security, and roaming IBM 17

18 Network Options LoRa system solutions available for both Macrocell/Microcell deployment Telecoms and others deploying LPWAN public networks (multi-tenant) Country wide deployments starting in multiple countries in early 2015 LoRa Microcell or Private Network (Macrocell) 18

19 Complete LoRa Ecosystem Complete ecosystem who are ramping to production with LoRaMAC compliant solutions Applications and ecosystem help make business case for nationwide public network deployments 19

20 Relationship Among LoRa Partners Semtech selling end-node and gateway IC Contributing to LoRaMAC system definition Reference designs for ecosystem partners Support of end-node source code and application development IBM and Actility offering complete commercial offerings based on LoRAMAC for nationwide deployments IBM Contact: Thorsten Kramp: Contact: Nicolas Jordan: Contact: Brian Ray: 20

21 Wrap Up LoRa TM enables the Internet of Things Disruptive technology for IoT and tracking of assets Provides outdoor and deep indoor connectivity Very low cost of ownership development and deployment Supports both local area network and nationwide deployments Scalable architecture makes it future proof for capacity and interference Strong ecosystem of partners and applications 11/4/
