Zigbee
ZigBee is a standard technology (IEEE 802.15) for communicating in a personal area network using
small, low-power digital radios.
It operates in the 2.4 GHz ISM band and utilizes a mesh network to provide low-power, wide-range
communication.
It has a transmission rate of up to 250 kbps and is best suited for data transmission in applications requiring
long battery life and security, periodic or intermittent data transmission, or simple signal transmission such
as sensors and input devices.
Applications include wireless light switches, remote meter reading, home automation, and personal and industrial
devices.
It provides security using 128-bit symmetric key encryption. The communication distance is about 10 to 100
meters.
