An IoT gateway is an intelligent central hub for IoT devices, that connects devices within the IoT to each other and to the cloud. This translates to communication among the devices, thereby filtering data to useful, relevant information.
An IoT gateway contains communication technologies that connect end-devices such as actuators, sensors & more complex devices. It also connects backend platforms such as data, device & subscriber management to the gateway. The integrated computing platform facilitates pre-installed or user-defined applications for data management, routing, computing at edge, devices, security, communication and other gateway functionalities.
Some of the most common uses of IoT Gateways are as follows:
Connection of devices to one another
Connection of devices to the cloud
Translation between IoT devices manufactured/operated by different firms
Data filtration
Security risk mitigation
Intelligence at the edge
Advantages of IoT Gateways utilization:
Inter-Device Connection & Connection to the Cloud
IoT Gateways allow for individual, remote control of devices from a centralized location that saves you time and effort. They can be programmed to work together and can be controlled individually.
The central hub provides a singular location where data is transmitted to and from devices, which comes from other devices and users via the cloud. The information that is transmitted or received from an IoT device is communicated to devices through IoT gateways via cloud-enabled software.
Data Filtration
The IoT gateway allows for devices to communicate with simplification. The data which is communicated is filtered into useful bits of information. IoT gateways are intelligent and have the capability to work at the edge, which means that each gateway can detect and filter through available data prior to dispatching the filtered data through the cloud, which improves communication as well as response timings.
Data Security & Risk Mitigation
With the expansion of IoT devices comes various security risks. IoT gateways provide added layers between the internet and the device, which allows for protection against security breaches and unwarranted hacking and attacks. A gateway enables additional security for your IoT devices.
Intelligence at the Edge
Data can be processed and interpreted by IoT Gateways, which eliminates the need for a third party or human intervention to decipher and process information. It is therefore more smart and autonomous to invest in IoT Gateways.
