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.
I've seen them starting at $3. check out froogle and search.
868 MHz and 902-928 MHz.
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.
Invented is the past participle of the verb invent. verb /past /past participle = invent /invented /invented
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.
yale was introduced zigbee in 25 sep 2010
quoting from stack exchange: "Zigbee", or IEEE 802.15.4, is a protocol. As such, it has no "programming language".
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 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.
