Zigbee is an IEEE 802.15.4-based specification for a series of high-level communication protocols used to create personal area networks with small, low-power digital radios such as home automation, data collection of medical devices and other devices low-power, low-bandwidth needs, designed for small-scale projects that need wireless. Therefore, zigbee is a wireless ad hoc network of low power, low data rate and close (ie personal area).
The technology defined by the zigbee specification is intended to be simpler and less expensive than other wireless personal area networks (WPANs) such as Bluetooth or more general wireless networks such as Wi-Fi. Applications include wireless light switches, home power monitors, traffic management systems, and other industrial and industrial equipment that require low-speed wireless data transfer.
Its low power consumption limits transmission distances to 10-100 meters line of sight, depending on output power and environmental characteristics. Zigbee devices can transmit data over long distances by passing data through a mesh network of intermediate devices to reach distant ones. Zigbee is typically used in low-speed data applications that require long battery life and secure networks (zigbee networks are protected by symmetric 128-bit encryption keys). Zigbee has a defined speed of 250 kbit / s, ideal for intermittent data transmissions from a sensor or input device. Zigbee was conceived in 1998, standardized in 2003, and revised in 2006. The name refers to the waggle dance of honey bees after their return to the hive.
