The main advantages of ZigBee are:
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.
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.
Zigbee components include Zigbee coordinator, Zigbee router, and Zigbee end devices. The coordinator is the main controller in a Zigbee network, the router helps in relaying data between devices, and the end devices are usually sensors or actuators that communicate with the coordinator or router.

quoting from stack exchange: "Zigbee", or IEEE 802.15.4, is a protocol. As such, it has no "programming language".
Advantages 1. low cost 2.low power consumption 3.highly reliable 4.secured Disadvantages 1.low transmission rate 2.smaller distance
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.

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.
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
To create a Zigbee network in OPNET, you first need to select the appropriate Zigbee protocol stack from the library or create a custom one. Then, set up the necessary network topology by placing Zigbee devices (coordinator, routers, and end devices) on the simulation canvas. Configure their parameters, such as transmission power and data rates, and define the application layer settings. Finally, run the simulation and analyze the results to evaluate network performance.
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.
