PPT On Zigbee
Zigbee Presentation Transcript:1. WHAT IS ZIGBEE?
Technological Standard Created for Control and Sensor Networks Based on the IEEE 802.15.4 Standard Created by the ZigBee Alliance
2. SENSOR/CONTROL NETWORK REQUIREMENTS
Large networks (large number of devices and large coverage area) that can form autonomously and that will operate very reliably for years without any operator intervention Very long battery life (years off of a AA cell), very low infrastructure cost (low device & setup costs) and very low complexity and small size Device data rate and QoS needs are low Standardized protocols are necessary to allow multiple vendors to interoperate
3. WHY ZIGBEE?
Reliable Mesh networking Low data-rate applications Very long battery life Secure Scalable Low cost Global applicability
4. HOW DOES ZIGBEE WORK?
Engineers feel Wi-Fi and Bluetooth may be unsuitable. This spawned the idea of digital radio networks via direct-sequence spread spectrum coding. ZigBee-compliant radios may operate on one of three different radio bands: the 800 MHz, 900 MHz, or 2.4 GHz frequencies. Follows the internationally recognized radio standard for the MAC and PHY Layer.
5. PC And Peripherals Desktop
PCs and Home Entertainment Systems (Home Theatre TV) Computer peripherals; HID devices Video conference equipment Remote control Video gaming equipment Multi-player PC & video games Remote controls for audio and video equipment
6. Human Input Devices (HID)
Keyboard Mouse / Pointing Device Remote Controls (controls for audio & video equipment) Gaming device Double Joystick
7. PATIENT MONITORING
May allow more patient freedom Monitors vital statistics and sends via internet Patient can remain in their own home Lowers cost and improves comfort Can be used in hospice care Patients are allowed greater movement Reduced staff to patient ratio Light way to bathroom when they get out of bed Reduces patient confusion
8. LIGHTING CONTROL
Wireless Lighting Control Dimmable ballasts Light switches anywhere Customizable lighting schemes Energy Saving on bright days
9. ZIGBEE VS BLUETOOTH ZIGBEE AND BLUETOOTH
ZigBee Smaller packets over large network Mostly Static networks with many, infrequently used devices Home automation, toys, remote controls, etc.
Bluetooth Larger packets over small network Ad-hoc networks File transfer Screen graphics, pictures, hands-free audio, Mobile phones, headsets, PDAs, etc.
