Whether the ZigBee gateway needs to be connected to the Internet depends on your actual needs. Normally, a ZigBee gateway needs to be connected to the Internet to communicate with other devices. This is because the ZigBee protocol itself does not support remote communication.
However, in some cases, you can connect the ZigBee gateway with the local network to control and manage local devices. In this case, the ZigBee gateway does not need to be connected to the Internet. In addition, ZigBee gateway is not a network interconnection device, but a middleware for managing wireless sensor networks. Therefore, it does not need to be connected to the network like a traditional router.
How does a ZigBee gateway work?
ZigBee gateway is a middleware used to manage wireless sensor networks. Its main function is to forward data from wireless sensor nodes to other devices or systems.
Specifically, when the wireless sensor node sends data to the gateway, the gateway will convert the data into a standard protocol format and send it to the receiver. At the same time, the gateway can also perform some additional functions, such as data filtering, routing, security management, etc.
In order to realize these functions, ZigBee gateway usually contains multiple modules, such as wireless transceiver module, data processing module, network management module, etc. Through the combination of these modules, ZigBee gateway can achieve efficient and reliable data transmission and management. In general, when using a ZigBee gateway, you need to pay attention to its networking requirements and make a choice based on the specific situation.
