What is an IoT Gateway?

Gateways can be an important part of an IoT solution, find out what they are and why they're useful. Nearly every IoT system requires some way to connect sensors/devices into the cloud so that data could be routed back-and-forth between them. IoT gateway can be essential in creating this connection potential because gateways act as bridges between sensors/devices and the cloud. Most sensors/devices will"speak" into a gateway and the gateway will then take all that information along with"talk" into the cloud.

At a high level, this is truly the way that mobile technology works too. Your telephone doesn't communicate directly with other phones, but instead communicates with the nearby cellular tower which then communicates with the mobile provider's (e.g. AT&T's) servers. Information then flows the opposite way, from the cellular provider's servers, to towers, to somebody else's phone. For IoT applications, the underlying concept is the specific same, simply change out gateway for mobile tower as well as the cloud for the mobile provider's servers. On top of this, IoT is generating unimaginable amounts of data. We may have heard the statistics.

A report from Gartner forecasts that by the end of 2019, a total of 14.2 billion things will be connected to the Internet. And this number will increase to 25 billion by 2021. Imagine billions of devices at the edge with various standards sending information to the Internet.This complex environment with enormous amounts of information is making IoT apparatus communicating challenging and slow!For now and later on, the IoT devices utilize a gateway as a central hub to fall sensed knowledge and communicate with external networks. The IoT Gateway stands as one of the key components in this ecosystem. It manages all communication together with sensors and remote connections like the world wide web, applications, or users.

In telecommunications, the principal purpose of a gateway is to provide a connection between different types of communication technologies. These technologies can alter in terms of connectivity types, interfaces, or protocols. This gateway links the WAN of the ISP through technology such as PPP or HDLC with your LAN with TCP/IP.The IoT Gateway follows the same principle of bridging communications for different technologies. It creates a bridge between the IoT sensors/actuators along with the Internet. The IoT gateway aggregates all data, translates sensor's protocols, and pre-process the information prior to sending it.
