Open Wireless Technologies Creating New Opportunities Wireless Integration Where are we with wireless? How does Wireless integrate into your building Operations Points to consider when choosing wireless The different types of Wireless for Buildings Enocean Wi-Fi ZigBee Z-Wave Applied Technology Use Case’s

Wireless Integration Buildings have many Different Connection Layers

Wireless Integration value proposition Get control Ideal for retrofits and new buildings Integrate HVAC, lighting & metering wireless control and networking options Get efficient Simplified engineering (application specific) Open, scalable and programmable Get value Reduce installation time and cost Expand your business into the small buildings market Supervision HVAC management Lighting management Energy management

How does wireless Integrate into your building operations? Wired/Wireless Wireless Enterprise & web servers TCP/IP TCP/IP Field controller Bus BACnet or LON BACnet IP/Ethernet BACnet MS/TP (B) Echelon (E)* ZigBee Pro (P) ZigBee Pro (P)

Where we are with Wireless? Mobile devices have changed our perception of Wireless Cellular 3G : 4G LTE WiFi Bluetooth Multiple Standards – We will focus on four EnOcean 6LoWPAN Wi-Fi DASH7 ONE-NET ZigBee Wibree WirelessHART ISA100.11a OCARI Z-Wave MiWi

Points to consider when Choosing a Technology Security What types are available with each technology Do they meet the needs of my organization? Installation Do I need special tools? Do I need special labor? What are my limitations for deployment? Point to Point Master Unit broadcasts to all others Distance and Obstructions critical Mesh Master Unit broadcasts Some units repeat to extend range Requires a good understanding of device ranges Hopping Allows extension of networks over longer ranges Need to be aware of hop limitations 3, 5 etc..

Points to consider when Choosing a Technology Self Healing What happens when a device looses power Power What will my power source be? Battery life How often do I have to change batteries? Who do I purchase batteries from? Range what are the distance restrictions? Bandwidth Will it interfere with my current networks Is network speed an issue Cost How does the cost compare with competitive technologies? Interoperability is it open and do I care?

Mesh Topology LAN

Network Hops – Related to Mesh Networks Hopping allows us to extend the network range In this example we are showing a Network with 5 hops If design range is 65 feet we can push the network out 325 feet from the coordinator Mesh Networks have limitations > Number of allowed Hops > Number of addresses a node can give out > Amount of resources (storage) available at the “coordinator” > More devices slower network speed

Value Proposition Wi-Fi devices allow for higher data throughput. They are easily connected to the Internet allowing access to data through remote servers. They provide pre-packaged easy to deploy wireless solutions/applications to the customer. Technology Adopters: Universal

Additional considerations -Open communication protocol -high data rates -Plug and play integration -Range 300 feet line of site

ZigBee Communication Protocol Self Healing Mesh ZigBee operates in the industrial, scientific and medical (ISM) radio bands: 2.4 GHz in most jurisdictions worldwide Applications HVAC, Lighting, Metering Power Battery and Powered Devices (24vac) Long life cycle battery (has to be 2 years or more) Security 16 channels 2 completely out of WiFi 128 bit encryption ZigBee Alliance 400 members ZigBee Devices For more information: www.zigbee.org

Value Proposition ZigBee enables low cost communicating devices that use self healing mesh technology to create more robust communication networks. Technology Adopters: Phillips Schneider Electric AT&T GE Honeywell

Additional considerations -Open for developers -Used Primarily for Metering, lighting and HVAC control -More than 7 manufacturers of ZigBee radios (lowers production cost) -Robust networks -Powered high power radio/battery (minimum of 2 years) for low powered radios (affects range) -Longer range 100-300 yards

Z-Wave Communication Protocol Mesh Z-Wave operates in the 908.42MHz band Applications Lighting, Access, appliances, consumer electronics Power Long life cycle battery Security Minimal security Z-Wave Alliance 250 members Z-Wave Devices For more information: www.z-wave.com

Value Proposition Z-Wave communicating devices use mesh technology to create more robust communication networks Technology Adopters: ADT Ingersol Rand

Additional considerations -Currently proprietary, an open standard is in the works - In the commercial space, used Primarily for Lighting and Access Control - typically battery powered -can operate in a power save mode transmitting 0.1% of the time -shorter range 100 feet and up to 4 hops (total of 400 feet)

Sensor Level Networks Enocean 902.4 MHZ Point to Point requires an EnOcean Chip Typical ranges are 45-65 feet through constructed walls No hopping Point to point WI-Fi 2.4 GHZ, 5GHZ Mesh, Open Protocol Typical reported ranges are around 100 meters (300 feet) in the open air Most deployments are point to point ZigBee 2.4 GHZ Mesh, self healing, Open Protocol Typical reported ranges are around 30 meters (90 feet) through constructed walls and 100 meters (300 feet) in the open air, 5 Hops (repeated signals) Star or tree topology Hopping Mesh Z-Wave 908.42 MHZ Mesh, requires a Z-Wave Chip Typical reported ranges are around 30 meters (90 feet) open air, 4 Hops (repeated signals) Star or Tree topology
