The document discusses the ZigBee wireless technology standard. It describes ZigBee as a standard created for low-power wireless networks to control sensors and other devices. Key points covered include that ZigBee operates at low data rates and power consumption, uses the IEEE 802.15.4 standard, and is designed for personal area networks and device-to-device communication between small packet devices like lights, switches and thermostats. The document also provides details on ZigBee frequencies, topology, states of operation, device types, and current uses in environmental and agricultural monitoring.

 915 MHz North American Band at
40kbps

6. What Does ZigBee Do?
 Designed for wireless controls and
sensors
 Operates in Personal Area Networks
(PAN’s) and device-to-device
networks
 Connectivity between small packet
devices
 Control of lights, switches,
thermostats, appliances, etc.

patterns of bees between flowers
 Symbolizes communication between
nodes in a mesh network
 Network components analogous to
queen bee, drones, worker bees
