2 Agenda ZigBee Overview IEEE 802.15.4 Radio
Network Topologies, Security, Battery Life Modules Description Driver Software Performance Sales Info 10/26/2006 Cores Electronic LLC

3 ZigBee Overview ZigBee is a wireless standard that aims to do for embedded command-and-control applications what Wi-Fi did for wireless networking. 10/26/2006 Cores Electronic LLC

4 ZigBee Overview The ZigBee standard and the lower level IEEE standard, are open standards targeted at home and building automation, consumer electronics, PC peripherals, measurement , medical applications and toys. 10/26/2006 Cores Electronic LLC

5 ZigBee Overview What these applications have in common is: 1) the need for low-power operation, and 2) the scalability to enable networks with thousands of devices. The IEEE is responsible for the standard, which defines the physical layer (PHY) and the media access layer (MAC). 10/26/2006 Cores Electronic LLC

6 ZigBee Overview The ZigBee Alliance is a global nonprofit consortium of over 60 industry leaders including Philips, Motorola, Honeywell, Invensys, Samsung, Mitsubishi, Microchip Technology, Freescale Semiconductor, Texas Instruments, etc. 10/26/2006 Cores Electronic LLC

7 IEEE Radio The IEEE standard specifies operation in the 2.4 GHz band which is available worldwide, and is also used by Wi-Fi and Bluetooth. 10/26/2006 Cores Electronic LLC

8 IEEE Radio The 2.4 GHz PHY employs offset quadrature phase-shift keying (O-QPSK). Direct sequence spread spectrum (DSSS) is used to improve receiver sensitivity through processing gain, and to ensure robustness in multi-path environments and in the presence of interfering signals. 10/26/2006 Cores Electronic LLC

9 Reduction in POWER implemented using SLEEP time
Network Topologies The simplest network is a STAR network with a single network coordinator connected to a number of slaves. Reduction in POWER implemented using SLEEP time 10/26/2006 Cores Electronic LLC

10 Network Topologies A second type of network is a cluster tree or connected star network. This type of network may be employed to extend the range of a star network or to link two networks. 10/26/2006 Cores Electronic LLC

11 Network Topologies The third type of network is a MESH network. A mesh network may extend over a large area and contain thousands of nodes. 10/26/2006 Cores Electronic LLC

12 Security The standard provides three levels of security: no security, access control lists and 32-bit to 128-bit AES encryption with authentication. The security mechanisms prevent data from being compromised, stolen, replayed or tampered with. 10/26/2006 Cores Electronic LLC

13 Battery Life ZigBee was designed from the ground up for ultra-low-power consumption. Many sensors will be battery powered. Taking advantage of the power-saving mechanisms built into the radio protocol and low-power microcontrollers (MCUs) can result in several years of operation from a single battery. 10/26/2006 Cores Electronic LLC
