GATEWAY and BEACON have specific meanings in the field of Internet of Things (IoT) and wireless communication.

เกตเวย์ :
GATEWAY in the Internet of Things usually refers to devices or systems that connect different networks or protocols for data exchange and communication between them. For example, in smart home, GATEWAY can connect home LAN and Internet, so that home devices (such as smart light bulbs, smart plug, etc.) can communicate with cloud services. GATEWAY usually has the functions of data conversion, protocol conversion, data caching and network security.

บีคอน :
BEACON usually refers to a low-power and small wireless sensor device in the Internet of Things, which is used to send broadcast signals to identify its existence. These devices usually communicate using Bluetooth or similar wireless technology. BEACON can be used in many applications, such as indoor positioning, object tracking, environmental monitoring and so on. By receiving the signal sent by BEACON, other devices or systems can determine their position or exchange other data. BEACON usually has the characteristics of low power consumption, long battery life and self-organizing network.

To sum up, GATEWAY is used to connect devices or systems with different networks or protocols in the Internet of Things, while BEACON is a wireless sensor device used to identify the existence and exchange data. They usually work together in Internet of Things applications to achieve more efficient data exchange and object tracking.
