What is ZigBee technology?
Zigbee is a standards-based wireless technology developed to enable low-cost, low-power wireless machine-to-machine (M2M) and internet of things (IoT) networks. Zigbee is for low-data rate, low-power applications and is an open standard.
Which one of the modulation techniques is used in ZigBee technology?
Zigbee uses DSSS as a spreading technique. DSSS is used to increase the frequency of the signal in order to increase its power and reduce the influence of noise from nearby networks. The 2.4 GHz band uses the Orthogonal Quadrature Phase Shift Keying (OQPSK) technique for chip modulation.
What is ZigBee technology explain its features and technical specifications?
Zigbee is a wireless technology developed as an open global standard to address the unique needs of low-cost, low-power wireless IoT networks. The Zigbee standard operates on the IEEE 802.15. 4 physical radio specification and operates in unlicensed bands including 2.4 GHz, 900 MHz and 868 MHz.
What is Zigbee technology PDF?
Zigbee is one of the most widely utilized Wireless Sensor. Network standards with low power, low data rate, low cost. and short time delay characteristics, simple to develop and. deploy and provides robust security and high data reliability. Name of the Zigbee came from zigzagging patterns of honey.
What is Zigbee architecture?
Zigbee protocol architecture consists of a stack of various layers where IEEE 802.15. 4 is defined by physical and MAC layers while this protocol is completed by accumulating Zigbee’s own network and application layers.
What are ZigBee protocols?
How many types of ZigBee are there?
ZigBee specifies three different device types: the ZigBee Coordinator (ZC), the ZigBee Router (ZR), and the ZigBee End Device (ZED). These three devices play different roles in a ZigBee network as shown in Figure 19.1.
Where is ZigBee technology used?
ZigBee is commonly used for wireless control and monitoring applications such as wireless sensor networks (WSNs), industrial plant monitoring, building control, hospitals, smart metering and home automation. There are public profiles defined in the ZigBee specification for many of these use cases.
What is application of ZigBee?
Zigbee is typically used in low data rate applications that require long battery life and secure networking. (Zigbee networks are secured by 128 bit symmetric encryption keys.) Zigbee has a defined rate of 250 kbit/s, best suited for intermittent data transmissions from a sensor or input device.
How do ZigBee devices communicate?
Zigbee smart devices communicate with each other using a radio transceiver. The chip operates on the IEEE 802.15. 4 protocol, over 2.4 GHz, which you might recognize as the same band used by Wi-Fi and Bluetooth. Unlike Wi-Fi, Zigbee has a shorter range of about 10-20 meters indoors because it uses less power.

What is ZigBee example?
A typical example is when you have a Zigbee-enabled light bulb and a Zigbee-enabled light switch and you want the light switch to control the light bulb. With Zigbee, the two devices – even if they’re from different manufacturers – speak a common language, so there’s no barrier to communication.
Why Zigbee is used?
Zigbee devices can transmit data over long distances by passing data through a mesh network of intermediate devices to reach more distant ones. Zigbee is typically used in low data rate applications that require long battery life and secure networking. (Zigbee networks are secured by 128 bit symmetric encryption keys.)
