IoT Gateways are hardware and software devices that act as intermediaries between IoT sensors and the Internet. They are responsible for collecting data from connected devices, managing communication between devices and the cloud, and processing and analysing the data before sending it to the cloud for further analysis.

Various industries use IoT Gateways to act as a central hub that connects IoT devices to the cloud. This means that daily operations, communication, and data transfer are done through the gateway.

Some of the common industries that rely on IoT Gateways include:

  • manufacturing
  • healthcare
  • IT and networking
  • retail
  • transport and logistics
  • smart buildings

The use of IoT Gateways is becoming increasingly popular as more devices become connected to the internet.

If your business does not yet use IoT Gateways, it is definitely worth it.

Read this article, where we’ll explain what IoT Gateways do, how they work, and why they are essential for any business looking to implement an IoT strategy. As a bonus, we also have a list of some of the top IoT Gateways available on the market today!

What Does An IoT Gateway Do?

In simple terms, they act as a bridge between connected IoT devices and the internet.

But let’s break it down further:

  • Data Collection: IoT Gateways collect data from sensors, devices, and other connected equipment. This is done using various communication protocols such as Wi-Fi, Bluetooth, and cellular networks.
  • Data Processing: Once the gateway has collected the data, it processes it before sending it to the cloud for further analysis. This can include data filtering, aggregation, and transformation.
  • Communication Management: IoT Gateways manage communication between devices and the cloud, ensuring a smooth flow of data without any hiccups or delays.
  • Security: As with any internet-connected device, security is a top priority. IoT Gateways provide secure connections between devices and the cloud, protecting sensitive data from cyber threats.
  • Protocol Translation: IoT devices often use different communication protocols, making it difficult for them to communicate with each other. Gateways act as translators, converting data from one protocol to another so that all devices can understand and work together.

How Do IoT Gateways Work?

Picture a Wi-Fi router—it connects all your devices to the Internet, allowing them to communicate with each other and access online services.

Similarly, but a bit more complex, IoT Gateways connect IoT devices to the cloud, enabling data transfer and communication between devices.

Here’s how it works:

  • The IoT Gateway is connected to a network.
  • Connected sensors and devices send data to the gateway through various communication protocols such as Wi-Fi, Bluetooth, or cellular networks.
  • The gateway processes the data and sends it to the cloud for further analysis.
  • The cloud then stores and analyses the data, providing insights and actionable information to users.

Why Your Business Needs It

The use of IoT Gateways provides many benefits for businesses, especially businesses looking to implement an IoT strategy.

An IoT strategy is a plan or framework that outlines how a business will use IoT devices and data to improve operations, reduce costs, and drive innovation.

Some of the key reasons why your business needs an IoT Gateway include:

1. Improved Communication

As mentioned earlier, IoT Gateways act as translators between devices using different protocols. This enables seamless communication and data exchange between devices.

2. Enhanced Security

With the rise of cyber threats, security is a top concern for any business with IoT devices. IoT Gateways provide an extra layer of security by securing connections between devices. They can also act as firewalls, preventing unauthorised access to sensitive data.

3. Reduced Costs

IoT Gateways can help businesses reduce costs by optimising processes and reducing downtime. For example, industrial manufacturers can use IoT Gateways to monitor equipment health and schedule maintenance before a breakdown occurs, saving time and money.

In 2018 SAB approached Brandwagon to discuss a custom tailored implementation
of our Digisign HMI Console workstation. After meeting with SAB's system manager and team we identified and implemented new and innovative solutions as outlined below:

The Challenge

To provide an integrated solution in an industrial environment by replacing the highly expensive Siemens and Allen Bradley HMI’s and PLC’s with a specifically tailored HMI for the bottling plant.

The Solution

Develop and engineer a cost-effective HMI panel to help the operator achieve higher levels of efficiency and increased performance by strategically placing HMI consoles on the floor where the operators can control and access the processes without having to walk to the control room.

Results of Implementation

The HMI workstations were tailored to their specific processes and needs and resulted in a greater level of plant automation.

The team has managed to integrate all the information on the condition of the bottling plant into the plant control system.


August 2018
  • SAB made contact with Brandwagon and elaborated on some of their HMI workstation needs.
  • The Brandwagon team realised a viable opportunity and setup a site visit at the Rosslyn plant. We met with the systems manager and his team to understand their requirements and took the opportunity to demo some of our state-of-the-art hardware components.
  • We did a thorough examination of the environment and positioning of their machinery on-site and received the initial scope on what was expected.
  • SAB required a custom-tailored HMI workstation and expressed their
    willingness to partner up with Brandwagon to start developing their own
    Digisign HMI Console.
September 2018
  • We incorporated all the components into a proposal with our concept drawings at our second meeting with the team.
  • We also submitted the first components costing breakdown and got
    confirmation to commence with the proof of concept.
  • Mid-September we discussed the design of the sheet metal enclosure with 2mm high-quality stainless steel 316 as the industry standard.
  • We briefed our draughtsman to start with the technical drawings and submitted the first drawings to the team for review.

Example of one our first concept drawings

October 2018
  • The drawings went back and forth with small changes made to ensure that the prototype will be safe to implement on one of the bottling lines. During October the first unit was signed off by SAB and in placed into production.
  • During the stainless steel fabrication, we delivered some of the hardware components to SAB for testing. This would ensure that the software will run seamlessly.
December 2018
  • The fabrication of the steelwork was completed and some of the hardware components passed the tests successfully.
  • SAB made provisions for a square tubing post for mounting and pulled
    network and power cables to the point of installation.
January - February 2019
  • SAB informed us that they are in the process of getting the point of installation ready.
  • Brandwagon staff did the safety induction, method statement and risk assessment.
  • SAB planned for the electrical and network contractors to be present for installation and the team came together on the 27th of February 2019 to install the first prototype on line 6 filler.
  • The prototype was successfully installed and tested until May 2019. It worked well but there were a few design changes on the stainless steel enclosure such as removing the ventilation slots and the HMI front to open upwards with a locking hinge to ensure safe inspection or maintenance of the HMI.
June, July and August 2019
  • We went back to the drawing board to implement the design changes. Changes were made and we brought in a versatile back plate for different mounting options:
September 2019
  • The final technical drawings of the HMI Console were submitted to the team and signed off for fabrication & production.
October 2019
  • Our vendor registration was completed; we submitted our final quotation and a PO were raised for the first IP65 19 inch HMI Keyboard Console to be installed on line 5.
  • By end of October 2019 fabrication of the Stainless steel 316 Console was complete and Brandwagon moved on to assembly, testing and packaging. On the 25th of October we delivered the first ordered unit to SAB Rosslyn.
