An IoT gateway is a hardware or software component that connects controllers, sensors, and other intelligent devices to the cloud. An IoT gateway, either a specialized hardware appliance or software program, is where all data traveling between IoT devices and the cloud is routed through. An intelligent gateway or control tier is another name for an IoT gateway.<\/p>\n\n\n\n

What is an IoT gateway?<\/h2>\n\n\n\n

Data is sent between IoT devices and the cloud using IoT gateways, which also serve as network routers. Early on, the majority of gateway devices just transmitted traffic from IoT devices to the cloud. A gateway device now frequently manages both inbound and outgoing traffic. IoT data is sent to the cloud using outbound traffic streams, and device management operations like firmware updates use incoming traffic.<\/p>\n\n\n\n

Some IoT gateways do tasks other than traffic routing. Sometimes the data can be preprocessed locally at the edge using a gateway device before being sent to the cloud. In order to reduce the amount of data that needs to be sent to the cloud, the device may deduplicate, summarize, or aggregate data as part of this process. This may significantly impact response times and network transmission expenses.<\/p>\n\n\n\n

An additional layer of security for the IoT network and the data it transfers is another advantage of an IoT gateway. The security of IoT devices has frequently been proven to be lacking, despite improvements. For instance, the TCP\/IP library, which is used by hundreds of millions of IoT devices, was found to include the Ripple20 vulnerability in 2020, rendering such devices vulnerable to attack.<\/p>\n\n\n\n

Adopting an IoT gateway with capabilities like tamper detection, encryption, hardware random number generators, and crypto engines is one method a business may use to secure its IoT network. These and other characteristics can help protect individual devices from assault and secure an IoT gateway.<\/p>\n\n\n\n

How does an IoT gateway work?<\/h2>\n\n\n\n

A straightforward IoT gateway performs similar duties to a Wi-Fi router. The gateway receives a Wi-Fi connection from an IoT system and then routes the data from the IoT device to the cloud. IoT gateways, however, are typically much more complicated.<\/p>\n\n\n\n

The fact that IoT devices use a variety of different protocols contributes to the fact that IoT gateways are typically more complicated than Wi-Fi routers. These protocols include Bluetooth Low Energy<\/a>, BACnet, Zigbee, and Z-Wave. As a result, in order to support all the IoT devices in an enterprise, an IoT gateway may need to handle a wide range of protocols.<\/p>\n\n\n\n

The gateway must be able to route every form of IoT traffic to the right location in addition to supporting these protocols. While data from building security sensors may need to be transmitted to a SaaS provider that runs a cloud-based security interface, data from a group of industrial sensors may need to be transferred to a database in the cloud.<\/p>\n\n\n\n

IIoT and edge computing are gaining traction in many industries<\/strong><\/a><\/p>\n\n\n\n

\n\n\n\n

IoT gateways may need to locally cache data in the event of an internet outage or if the gateway is inundated with more data than it can process, which is another reason why they may be more complex than Wi-Fi routers.<\/p>\n\n\n\n

IoT gateways frequently offer failover clustering or the capacity to scale out in order to handle growing workloads.<\/p>\n\n\n\n

Edge computing and IoT gateways<\/h2>\n\n\n\n

Some IoT devices generate enormous amounts of data. If a company has a sizable IoT ecosystem of devices and wants to send data from all of those devices to the cloud, this could be an issue. The IoT gadgets might possibly use up all of the company’s internet capacity and cost a lot to store data in the cloud.<\/p>\n\n\n\n

Using edge computing for at least some of the essential data processing can help prevent these kinds of issues. By lowering the amount of data that must be transferred to the cloud, this method aids in lowering costs and bandwidth usage.<\/p>\n\n\n\n

Let’s say a company has a collection of IP-enabled security cameras that are all transmitting real-time data. Sending all of the unprocessed surveillance footage to the cloud for data processing definitely wouldn’t make much sense. This is particularly true if some of the cameras mainly focus on vacant spaces.<\/p>\n\n\n\n

It is more effective to process the video footage at the edge rather than uploading all of the surveillance footage instantly. The edge device may distinguish between security film that the company deems worthy of keeping and footage that is inconsequential, such as video of an empty room. The footage that has to be evaluated can be sent from the edge device to a gateway device, which uploads the information to the cloud.<\/p>\n\n\n\n

IoT gateways are crucial for controlling and protecting IoT devices, and they could also aid a company in lowering the bandwidth usage associated with IoT.<\/p>\n\n\n\n

IoT gateway architecture<\/h2>\n\n\n\n

Four architectural layers can be found in IoT infrastructure. These consist of the following:<\/p>\n\n\n\n
