What keeps IoT networks glued together?

An IoT gateway is a centralized intelligence hub for Internet of Things (IoT) devices. IoT gateways connect devices and the cloud, translating data between them and filtering it into useful information.

An IoT gateway connects end devices to backend platforms, such as sensors, actuators, or more sophisticated devices. IoT gateways have a computing platform that allows pre-installed or user-defined programs to manage data (for routing and processing at the gateway), devices, security, communications, and other aspects of the gateway.

IoT Gateways are essential in establishing strong IoT networks and allowing for computational power for edge computing scenarios. IoT gateways handle data processing at the source, or "edge," to distribute the burden, rather than depending on central servers.

An IoT gateway can be a dedicated hardware appliance or a software program

What is an IoT gateway?

An IoT gateway is a physical device or software program that connects the controllers, sensors, and intelligent devices to the cloud. All data transfers between IoT devices and the cloud must go through an IoT gateway.

An IoT Gateway is comparable to a home or office network router or gateway. Such a gateway allows your devices to communicate, keeps them relatively secure, and offers an admin interface where you can perform basic tasks. An IoT Gateway accomplishes these and much more for IoT networks.

How does an IoT gateway work?

An IoT gateway is similar to a Wi-Fi router in function. An IoT system connects to the gateway using a Wi-Fi connection and transmits device data to the cloud. However, IoT gateways are typically far more complex.

Another reason an IoT gateway is much more complex than a Wi-Fi router is that numerous different IoT protocols exist. Z-Wave, BACnet, Bluetooth Low Energy, and Zigbee are just a few of the protocols employed by IoT devices. As a result, an IoT gateway must be capable of handling many protocols.

The gateway must be able to route each type of IoT traffic to the correct destination in addition to supporting these protocols. Data from various industrial sensors may need to be electronically transferred to a cloud database. In contrast, data from building security sensors might require transferring to a SaaS vendor that offers a cloud-based security portal.

IoT gateways need to cache data locally in the event of an internet outage or if the gateway receives too much information. Furthermore, IoT gateways frequently include failover clustering or the ability to scale up to support increasingly huge workloads.

Benefits of IoT gateways

IoT Gateways have evolved to perform various functions, from simple data filtering to sophisticated analytics. These intelligent devices are playing a crucial role in the current IoT revolution.

Device and cloud connection

An IoT gateway is a hub for data sent to and from devices. This communication comes from other gadgets via the cloud. When you give data to an IoT device, such as a protocol change, you interact with it through IoT gateways powered by cloud-enabled applications.

IoT gateways can also connect to simplify and expand their capabilities across a physical location, and they're becoming increasingly popular among IoT gadgets and smart sensors. You may add devices effortlessly while saving time and effort by adopting unified IoT gateways early in your technology plan.

Data filtering

IoT gateway allows your devices to communicate with one another, but it also reduces the number of steps required for them to do so by filtering data into useful chunks. Because IoT gadgets can capture new bits of information in a fraction of a second, seeing every record would be useless and slow down how quickly the systems operate and talk. IoT gateways can work at the edge. This implies that rather than sending everything to the cloud, it should consider and analyze the data it receives before merely delivering necessary, filtered information to the cloud, improving communication and reaction times.


As IoT devices increase in numbers, so do the security risks they present. You've heard stories about the Internet of Things going wild, including Wi-Fi baby monitors that allow intruders to eavesdrop and smart automobiles that go out of control. IoT devices are vulnerable to outside influence and hacking; however, an IoT gateway adds another barrier between the internet and the device. Even if your firm doesn't plan to spend much on IoT, a gateway allows for further investment in the future while also increasing security for existing IoT gadgets.


The term "intelligent edge" refers to devices capable of receiving and interpreting data from the Internet of Things (IoT) independently, without the need for a third party or human intermediary. IoT gateways are an illustration of the intelligent edge in operation.

What is IoT edge computing?

The internet of things can benefit from more computing power closer to the physical device or data source. Rather than sending data back to a central location before it can be analyzed, it must be examined at the edge since IoT devices cannot react faster or solve problems independently.

IoT devices' data and computing needs can be covered locally with edge computing. Here are a few advantages to integrating IoT and edge technologies:

  • Increased efficiency of data transmission between Internet of Things (IoT) devices and enterprise IT networks

  • Better response times and increased operational efficiency

  • Improved bandwidth

  • When a network connection is lost, the system operates, albeit offline

  • This approach is based on local data processing, aggregation, and rapid decision-making via analytics algorithms and machine learning

IoT gateways can send data from the edge to the cloud or a centralized data center and edge systems for locally-processing.
