XBee et Zigbee

There is often confusion between modules XBee company And agreements ZigBee company, usually referred to as a module ZigBee company, considering the module XBee company-Yes. However, the latter does support the agreement ZigBee companyBut not just:

XBee companyAnd ZigBee companyIt has many things in common. XBee is a family of radio modules and is a registered trademark of digi international. ZigBee is a wireless communication protocol, which is the trademark of ZigBee alliance. Many people confuse the two names because they are both involved in the radio network and have "bee" in their brand name. But they are totally different. Let's compare XBee and Zigbee to better understand what they are, what they are different, and the relationship between them.
 
ZigBee company It is a kind of wireless communication protocol suitable for low-power wireless local area network. It has the characteristics of modern security, standard-based, and global operation. It is widely used in home automation, intelligent energy, wireless sensor and industrial automation.
 
XBee company Refers to the brand name of digi international equipment family. Digi XBee wireless modules share common shape factors, standard host interfaces, support tools and software, and a set of protocols, including Wi Fi, cellular LTE, number And ZigBee company -Yes. Therefore, there are XBee modules that implement ZigBee protocol, but not all xbees are ZigBee, and vice versa.

ZigBee introduction

ZigBee logo
agreement ZigBee company It's a standard, just like Bluetooth is a standard. A fully ZigBee enabled manufacturer device can communicate with any other company's ZigBee device. So just as Apple's Bluetooth beat headset can be connected to Samsung's Galaxy smartphone, any of GE's ZigBee lighting switches can communicate with Phillips's ZigBee lights or any other ZigBee certified device.
 
How does it work? Well, like a good cake, robust network protocols are about layer-Yes. Each layer has added features and functions with enough independence, so the implementation changes in one layer do not need to modify any other layers. ZigBee company Is the protocol layer that defines wireless network elements, such as how to start the network, perform address resolution, and route packets. It also specifies how to use predefined means of communication to implement certain applications, such as lighting control, intelligent energy system management or environmental monitoring.

The lower layer ZigBee company Supporting its advanced functions is called IEEE 802.15.4. This is a set of standards that define how to use the radio spectrum and many other operations that facilitate reliable transmission. Brand radio module XBee company Digi can configure ZigBee or not. There is even a configuration that directly supports the native form of 802.15.4.
 
ZigBee company It adds three important functions:
  1. Grid routing -Use the routing table to define how the radio sends messages to There is also a series of other radios on the way to the final destination.
  2. Creating ad hoc network -An automated process to create a complete radio network in flight without any human intervention.
  3. Self healing mesh -The process of automatically detecting whether one or more radio stations are not in the network and reconfiguring the network to repair the interrupted route.
Per network ZigBee company Assign different roles to wireless modules or nodes. These include:
  1. Coordinator -The station is responsible for the formation of the network, address assignment and management of other functions that define, protect and maintain the network. Each network must consist of a coordinator and There will never be more than one coordinator in your network.
  2. Router -The router is a complete ZigBee node. It can join the existing network, send information, receive information and route information. Routing is to act as a messenger between other devices that are too far away to transmit information by themselves. Routers are usually plugged into power outlets because they have to be permanently turned on. ZigBee networks usually have multiple radio routers.
  3. terminal equipment -The final device is basically a simplified version of the router. They can join the network, send and receive information, but that's all. They don't act as messengers between other devices, so they can use lower cost hardware and shut down intermittently, saving energy by temporarily switching to mode Standby (none) answer. Terminal devices always need a router or coordinator as their parent device to help them join the network and store messages during sleep. ZigBee network can have any number of terminals.

ZigBee on XBee

XBee ZigBee products

ZigBee company Is a sharing protocol, so chips and modules are available from many manufacturers. This kind of standardization is the key element of its value. What makes ZigBee Digital XBee especially? First of all, digi created an excellent implementation, one with the highest engineering quality, and fully passed the interoperability certification of ZigBee alliance. These basic elements are just the foundation.

Standardized host interfaces facilitate fast, easy to understand configuration, control, and communication. Users can choose a simple human-readable at command or a structured API for machine-to-machine interaction. The combination of module shape factors means that Digital XBee It can be inserted into temporary socket or permanently welded on PCB. These standard dimensions include a very small micro size that integrates the power of XBee into a module no bigger than a nail.

Digi extends its security framework Trust fenceOn the module, including security guidance, security identification and confidentiality. Each module is user programmable, so it can support application logic, sensor input, power management and so on without additional microcontrollers. Finally, there is the power of the digi XBee ecosystem. If a part of the project needs to be migrated to different communication protocols in the future, there is no need to change the module schematic diagram, shape factors, host interface or embedded program, which makes the change between standards very simple.

Let's take a closer look Digital XBee Understand how this happens.
