Today the IoT Gateway is frequently defined as the artificial intelligent bridge between a network (or its components) and the cloud (or business applications or anything external, where the information goes to/from) on one side and the actual edge (the human end) on the other. With the latter, the use of software to control and manage industrial IoT networks becomes a lot easier. Consider this scenario. You want to open a coffee shop within an industrial area, but you are hesitant because the local regulatory commission does not allow for such a business because of the security implications.
This is where the industrial iot gateway comes in handy. Through this hardware, you can enable your smart phones or tablets to act as digital IP cameras so that you are able to capture images of the front door and the property line. You can then connect this data to the cloud using public cloud servers and load such data into the cloud in real time – meaning that the images can be accessed by the customers sitting at any location in the world and the business can be transacted even while they are on vacation.
There are several types of industrial iot gateways that you can choose from. The first one we will discuss is the packet switch or the STP iot gateway. In this type, the device receives all the signals and then sends them through a collection of devices. These devices are called forwarding devices or servers. They first verify if all the signals are valid and then determine the best path to take thus forwarding the data to the right device.
One of the advantages of using the STP smart edge devices is that they are connected to the internet without the need for any additional hardware. This is why they are quite popular among industrial device operators. Also, STP devices are able to use different protocols so that they can work with different network topologies. An example of this is the High-speed Transport Protocol (HSTP) which is used by Ethernet over ATM devices.
Aside, from forwarding data, STP industrial gateways can also help with time and geographical intelligence. This is because they can detect routes based on geographical proximity. The information gathered can include travel time and routes, traffic jams, traffic lights, and other factors that an operator would want to use in order to plan their operations. In order to do this, the iiot gateway uses Real Time Traffic Analysis (RTA).
On the other hand, the On-board Computer Architecture (OCA) allows remote service providers to access on-board sensors and functions via internet or radio frequencies. With the OCA, the gateway can be configured to forward signal requests to the relevant devices. Then, once the request is received, the information is transmitted over either radio or internet frequencies to the on-board sensor. Through this process, real-time analytics is provided to operators. Overall, an industrial OCA is made up of a router, an edge device, STP gateway, and an application service provider.
