The main advantages of ZigBee are:
- Power saving, as a result of the short working period, low power consumption of communication, and standby mode
- Reliability: Collision avoidance is adopted, with a special time slot allocated for those communications that need fixed bandwidth so that competition and conflict are avoided when transmitting data. The MAC layer adopts completely confirmed data transmission, that is, every data packet sent must wait for the confirmation from the receiver
- Low cost of the modules, and the ZigBee protocol is patent fee free
- Short time delay, typically 30 ms for device searching, 15 ms for standby to activation, and 15 ms for channel access of active devices
- Large network capacity: One ZigBee network contains one master device and maximum 254 slave devices. There can be as many as 100 ZigBee networks within one area
- Safety: ZigBee provides a data integrity check and authentication function. AES-128 is adopted and at the same time each application can flexibly determine its safety property.
The main disadvantages of ZigBee include short range, low complexity, and low data speed. Due to their high cost, GSM and GPRS are normally used in concentrators to transmit data to the main station, or in high end multi-function meters. ZigBee is used mainly in the concentrators, data collectors, repeaters, and meters installed in the urban distribution AMR systems and prepayment systems. Because of the good real time capability of RF, meters are often equipped with a remote control function.

Advantages and disadvantages of zigbee technology?
Zigbee technology has many different advantages and not a lot of disadvantages. Some advantages include lower costs and it can work in any type of market even with low power sensors. A disadvantage is that it is a bit slower than other technologies.
Who introduce the zigbee?
yale was introduced zigbee in 25 sep 2010
Programming languages that control zigbee?
quoting from stack exchange: "Zigbee", or IEEE 802.15.4, is a protocol. As such, it has no "programming language".
What are advantages and disadvantages of zigbee wireless technology?
Advantages 1. low cost 2.low power consumption 3.highly reliable 4.secured Disadvantages 1.low transmission rate 2.smaller distance
Zigbee is full duplex?
Yes. Actually we can communicate with ZigBee module through UART. So UART itself is a full Duplex communication. So we can use ZigBee for full Duplex communication.
Who invented zigbee?
IEEE
What is cost of zigbee transceiver in India?
500000 ...........
What is the Zigbee Module for?
The ZigBee module is a collection of high level protocols used for communication that can be used to create personal area networks from digital radios.
What is the comparison between ZigBee and RFID?
It depends on the application. RFID usually means passive tags, low cost and no battery needed but maximum range only a few inches. Zigbee ia a PAN network (the nodes all have batteries) range is many yards. RFID tags generally cost less ($5?) than Zigbee nodes ($25?) but prices vary with quantity. With RFID to locate something you must scan it from a few inches away. With Zigbee you can detect it from anywhere in the building. But, Zigbee does not inherently give any location information
What is zigbee?
ZigBee is a standard (rules, specifications, etc.) of a wireless network. This network aims specifically for home devices and appliances by making each 'node' 'speaks' with another, and benefit from each other.
Operating range and frequency of zigbee?
2.400 Ghz - 2.483 Ghz
What are the waves used in zigbee communication?
ZigBee operates in the industrial, scientific and medical (ISM) radio bands: 868 MHz in Europe, 915 MHz in the USA and Australia, and 2.4 GHz in most jurisdictions worldwide.
