which maintains the integrity of the information flow. A diagram of a possible ZigBee
network is shown in the figure.
Pic.1. ZigBee network diagram
The IEEE 802.15.4 standard allows the use of multi ple frequency bands to organize
communication channels. In addition, the 2.42.48 GG transmission speed is the highest
and provides the best noise. For these frequencies, 16 channels were tuned at 5 MHz.
Additional data transfer rate, including data rate, is 250 kbit / s. The ZigBee protocol
allocates 16 bits of data per device address, allowing a single coordinator to manage up
to 65,536 devices.
Like any protocol, ZigBee has its drawbacks. Major updates in 2006 and 2007 caused
compatibility issues with devices with different protocol versions. In particular, this
problem occurs when ZigBee 20062007 devices are combined with ZigBee Pro devices.
Devices that support one version of the protocol, if they are the last device, may work
properly with other devices in the network that have a different protocol version. This is
due to differences in routing princi ples.
In addition, devices running on ZigBeed must be assigned one of the standard target
profiles: Industrial plant monitoring; enterprise monitoring; Home automation; Automation
of commercial buildings; Telecom programs; outpatient or inpatient treatment at home
and in the hospital, and so on.
Due to the low power consumption and high interruption resistance of devices
operating under the ZigBee protocol, their coverage includes various systems of building
automation, industrial control and monitoring. The ZigBee protocol is very flexible and
has a wide range of capabilities for setting up local wireless networks. Ease of installation,
safety, reliability, low power consumption, and cost of components make it one of the
most popular protocols for creating room automation devices.
Conclusion
The article discusses the technical and practical features of the ZigBee wireless data
transmission protocol. The device network built on this standard, its scope, advantages
and disadvantages were discussed in detail. To be more specific, descri ptions are given
that are comparable to other popular protocols such as WiFi and Bluetooth.
