ZigBee Wireless Technology The BAS Market Place is Readily Adopting ZigBee as the Primary Wireless Technology

ZigBee is the name of a specification for a suite of high level communication protocols using small, low-power digital radios

ZigBee technology is intended to be simpler and cheaper than other Wireless Personal Area Networks (WPANs) such as Bluetooth

ZigBee is targeted at radio-frequency (RF) applications that require a low data rate, long battery life, low cost, and secure networking

ZigBee utilizes the IEEE 802.15.4 physical layer

7

Why ZigBee? Standards Based, Reliability, Low Cost ZigBee is a standards based, committee regulated, international protocol “The ZigBee Alliance is a global ecosystem of companies creating wireless solutions for use in home, commercial and industrial applications. It is the only global wireless communications standard enabling the development of easily deployable, low-cost, low-power monitoring, and control products.”

Membership: The Power of Many ZigBee Alliance members come from a broad spectrum of industries Alliance has more than 200 member companies.

Standards-Based The ZigBee Alliance standardized its specification on top of the Physical (PHY) and Medium Access Control (MAC) layers of the IEEE 802.15.4 global standard; adding the application profile layers, security and network layers to create ZigBee. The intent is that vendor-independent product solutions will be interoperable. Not there yet…Stack is continually evolving just as BACnet implementation was in the 90s.

Mesh Network Features The continuous flow of communication exacted by a mesh network topology provides the reliability required for wireless-based connectivity of remote monitoring and sensing controls.

Served Markets ZigBee is designed to address the unique needs of low-cost, low-power, wireless sensor networks for remote monitoring, home control, and building automation network applications.

Why ZigBee? Rapidly Adopting Customer Base, Multi-sourced Chip Providers

Quickly becoming industry standard for wireless peripheral communication  Southern California Edison will have in place 5 million ZigBee wireless nodes for electric, gas, and water utility meter reading in homes, 2009-2012

ZigBee radios and integrated microprocessors are available from multiple vendors  Texas Instruments™  Oki™ Semiconductor  Ember™  Freescale™ Semiconductor Processor Radio

ZigBee and BACnet The Partnership Solidifies ZigBee in the Commercial Building Industry

“BACnet is partnering with ZigBee because we see a number of strengths by working together and creating a mutually beneficial relationship by marrying our technologies. Our teams are dedicated to working very closely to deliver long-term value for the commercial building industry.” Bill Swan, BACnet Committee chair

Just this year, BACnet added ZigBee as it’s FIRST wireless data link!

Overview of ZigBee Technology Origin Of ZigBee Name The name ZigBee comes from the domestic honeybee, which uses a zig-zag type of dance to communicate important information to other hive members. This communications dance (the "ZigBee Principle") is what engineers are trying to emulate with this protocol -- a bunch of separate, simple organisms that join to together to tackle complex tasks.

11

Overview of ZigBee Technology Based Upon IEEE 802.15.4 Physical Layer

Up to 16 different channels on the 2.4 GHz band to secure non-interference with other wireless devices.

12

Overview of ZigBee Technology Secure - DSSS and Last But NOT Least, MESH

Multi-frequency Direct Sequence Spread Spectrum technology - DSSS  “Chipping” of communication data to filter out competing RF signals…equates to more reliable RF transmissions  Turns data into white noise…making it indecipherable for non 802.15.4 radios, aka WiFi

13

Overview of ZigBee Technology ZigBee Mesh – Node Types

ZigBee Mesh Networks Have 3 Types of Nodes Coordinator  Starts the network  ZFR1810, TEC Coordinator, WRZ7860

Routers  Creates the Mesh by routing data ..i.e BACnet messages  ZFR1811s, Wireless TECs

End Devices  Sleeping nodes  WRZ series Sensors

14

Overview of ZigBee Technology Wireless PANs

Wait a second… What if you have multiple Coordinators in close proximity operating on the same radio channel?

PANs solve this dilemma  A Personnel Area Network is a local area network identifier that supports up to 64,000 unique addresses  PANs are similar to LANs and WANs in wired IP based networks  Each Coordinator Owns the PAN
