2 Welcome! The goal of TridiumTalk is to share with the Niagara community timely content on sales, products and technical topics. Each session will last between minutes and will be a mix of presentation, demonstrations and Q&A. This session and past sessions will be posted on our community web site at The content presented here is representative of Tridiums Niagara technology and products in general, please contact your channel partner for specific details and pricing. As a courtesy to others in the conference, please place your phone on mute until the Q&A portion of the program

3 Sedona Framework and 6loWPAN The Sedona Framework and 6loWPAN - A Platform for Small Devices / The Internet for Wireless Devices This session of TridiumTALK is an educational forum focused on wireless technologies, the benefits of wireless networks in real world building automation applications, and an introduction to the Sedona Framework, Tridium's newest embedded device technology that distributes decision making control and manageability to any device and brings intelligence and connectivity to the network edge and back.

4 Agenda Wireless Technologies Wireless Microcontroller IPV6 6LoWPAN Sedona Framework

5 Wireless Technologies Power Lighting HVAC Enterprise Applications Server Cellular Networks PAN Networks Security WiMAX & WiFi Networks PDA/Smart Phone Browser Client Building Controller

6 Wireless Technologies Cellular (2.5G & 3G - > 10,000m) –EDGE/HSDPA (Cingular) –EV-DO (Verizon,Sprint/Nextel) MAN (Municipal Area Network - 10,000m) – WiMax - Worldwide Interoperability for Microwave Access LAN (Local Area Network – 30 to 100m) – a,b,g,n WiFi PAN (Personal Area Network > 30m) – / Zigbee / 6loPAN –RFID & Bluetooth

7 Multiple Wireless Protocols Controllers will need to support multi- wireless protocols Multiple ports and multiple antennas Same story as wired world multi protocols just no wires! Need for both a gateway and integration platform

8 Wireless Value Proposition Installation cost Resource savings Implementation time Ideal for moving and movable assets Operational Savings –Travel, Labor

9 Wireless Issues & Concerns Batteries –Replacement labor –Environmental Issues –New battery and power technologies Loss of Service –We deal with it every day –Must be considered –Self healing networks and smart routing

10 What is ? IEEE standard for low cost, low speed, low power wireless communication Targeted at device to device communication Supports multiple frequencies, including the worldwide unlicensed 2.4 GHz band –Sixteen channels –Shares spectrum with (WiFi) and Bluetooth 250 kbit/s data 2.4 GHz 127 bytes max packet length Each device has a unique 8 byte identifier (MAC address)

11 Networks specification defines methods by which devices can form networks –Networks are known as Personal Area Networks (PANs) –Each network has a unique PAN ID –Three type of nodes – coordinator, routers, end device Network is managed by the coordinator –When end devices start up, they broadcast a request to associate with a network –Coordinator will respond to association request and assigns address to device, updates routing tables throughout the network Multiple network topologies supported, but not specified by standard. –types include star, tree, linear and mesh –Each topology requires a different routing algorithm

12 Star Network Simplest network All traffic routed through coordinator Limited coverage and quantity since all nodes must be within RF range of the coordinator Requires smallest code and memory footprint End devices can sleep to conserve power

13 Tree Network Larger coverage area than star network Messages between nodes must get routed to first common ancestor End devices (G & H) can sleep Moderate code and memory requirements A self-healing tree can re-route automatically if link to parent is broken –Example: If G loses communication with E, it could become a child of B

14 Linear Network Specialized version of the tree network with similar code and memory requirements Large coverage area Single path between all devices

15 Mesh Network Each node dynamically determines best path to other nodes, changing its routing as paths fail or degrade Most complicated routing algorithm, requires largest code and memory footprint All devices that perform mesh routing must be powered

16 Hotel Case Study Hotel PTAC Unit Control Cost Sensitive Product Cost Sensitive Industry Low Tech Install and Maintenance Potential for Savings –Energy and Operational Only cost effective solution was wireless Technology had to be Built-In –A PTAC Control Appliance

17 Front Desk Wireless Appliance Architecture Browser Web Based Controller Local Area Network Wireless Network Wireless Node

18 Gateway & Controller Gateway Node Full Function Node Orbital Node Gateway Node supports communication to the network via wireless protocol Full Function Nodes automatically form and manage the network as routers Orbital Nodes support the device application and are managed by Full Function Nodes



21 Wireless Microcontroller Wireless Microcontroller – More than a radio –32-bit RISC –Low Power –Long Range –Chips, Modules, Evaluation Kits Wireless Networking Software –Standards-based IEEE , ZigBee, IPv6 –Highly secure –Co-existence with other wireless infrastructure Applications –High volume consumer markets –RF Remotes, Toys, Gaming –Industrial, Building, Medical –Automotive, Metering, Asset Tracking

22 Wireless Connectivity Solution Wireless Microcontroller –Highly Integrated Single Chip Solution –Feature rich microcontroller + IEEE compliant transceiver Networking Stacks –Designed for flexibility, low power operation, co-existence, stability and robustness –For sensor and control networking

23 IPv6 Next generation of Internet Protocol (IP) addressing scheme Expands address space from 4 bytes to 16 bytes –2 128 bits worth of address space –~3.4 x addresses Lots of address space = well suited for addressing devices and M2M applications –Every switch, lamp, appliance, etc. in your home can now have its own IP address Uses different notation for specifying addresses –IPv –IPv :0db8:0000:0000:a526:2962:3960:c0e1

24 What is 6LoWPAN? 6LoWPAN = IPv6 over Low power Wireless Personal Area Networks Internet standard defined by IETF –RFC4944 – Transmission of IPv6 packets over IEEE – –Large open community concerned with evolution of the Internet architecture – network designers, operators, vendors, researchers Enables wireless devices to interoperate with other IP-enabled devices using standard protocols An extension of wired IP into the wireless domain….. –Benefits: global addressing / routing – its a Standard.. –Devices have globally unique addresses

25 6LoWPAN - Purpose To extend IP services down to low power, embedded wireless devices – sensors, controls, actuators Enabling IP and wireless to work together –Small packet sizes, low power consumption, a protocol stack suitable for embedded devices – small footprint, efficient 6LoWPAN defines IPv6 packets over IEEE –Packet fragmentation, header compression, multi-hopping –Compact and efficient implementation for low power wireless Clusters of wireless nodes connected to the wired infrastructure –Nodes within a cluster talk wirelessly –Nodes on different clusters talk through the wired domain Benefits from reuse of existing IP infrastructure –Simple integration and deployment

26 Why use 6LoWPAN? Leverages existing standards –IP is the field-proven protocol winner Generic solution regardless of device or application type –Permits integrating devices without requiring gateway cognizant of the application A programming tool can communicate directly to a device without special application software and mapping, communications are simply routed through the network! Works with wired and wireless devices, just like the computer world, just like the telecom world. A smart 6LoWPAN router can present an IPv4 address. In this case the router will have a configuration table to handle mapping the extended address to IPv4 addresses.
