Devices such as IOT gateways enable communication between IoT devices, sensors, equipment, and systems. Basically, an IoT gateway is a central HUB for all IoT devices. It connects the IoT devices to each other and to the cloud, converting communication among the devices and analyzing data to create useful information. Several critical functions are performed by an IoT gateway, including translating protocols, encrypting, processing, managing, and filtering data. As part of an IoT ecosystem, gateways sit between devices and sensors to COMMUNICATE with the cloud.  

IoT gateways are commonly used for the following purposes:   

  • INTERCONNECTING devices
  • Connecting devices to the cloud
  • Transforming IoT communications
  • Data filtering
  • Reducing SECURITY risks, etc.
