- 1. Zigbee communication Presented by RABIN CHANDRA SHIL BWU/MCA/18/049 Course code : 502B 1
- 2. What is zigbee ? Zigbee is an IEEE 802.15.4-based specification for a suite of high-level communication protocols used to create personal area networks with small, low-power , Low cost wireless connection made for Internet of Things and Machine to Machine Network. Created by the ZigBee Alliance . Philips, Motorola, Intel, HP are all members of the alliance . 2
- 4. Why Zigbee is needed ? No wireless network standard that meets the unique needs of sensors and control devices. wireless systems don’t require high data rates but do require low cost and very low current drain. proprietary systems are creating significant interoperability problems with each other and with newer technologies 4
- 5. Features of Zigbee Low power consumption High density of nodes per network Simple protocol, global implementation Network Flexibility Small size-less than 9 mm*9 mm Hundreds of devices per Network 5
- 6. Zigbee characteristics Data rates of 20 kbps and up to 250 kbps Star or Peer-to-Peer network topologies Support for Low Latency Devices Handshaking Low Power Usage consumption 3 Frequencies bands with 27 channels Extremely low duty-cycle 6
