A communication gateway is a device or software system that acts as an intermediary between different networks or communication protocols, enabling data to be transmitted between them. The purpose of a communication gateway is to enable devices or systems that use different communication protocols to communicate with each other seamlessly.
For example, a communication gateway may be used to enable communication between devices that use different types of wireless communication, such as Bluetooth and Wi-Fi. Similarly, a communication gateway may be used to enable communication between devices that use different network protocols, such as TCP/IP and UDP.
Communication gateways are commonly used in industrial automation and control systems, as well as in smart homes and Internet of Things (IoT) applications. They play a critical role in enabling interoperability and communication between devices and systems that may use different communication technologies or protocols.
