This is the third article in a four-part series on IoT basics. Part 1 introduced IoT devices, and Part 2 explored the details of IoT device management. If you’ve made it this far, you might be ready to start your IoT development project. Here, we’ll walk you through device design and deployment.
Many companies that manufacture IoT devices start out as legacy manufacturers. Suppose you already have a product on the market. You’ll soon be falling behind the “smart” versions of the same. So we need to add a little bit of ‘internet’ to ‘things’ to update the product for his IoT era.
You might think that your experience in designing and manufacturing products and devices will give you an advantage when moving to IoT. Maybe so. But don’t make the mistake of applying standard design principles to your connected devices. IoT products require a different approach.
why? Because we don’t just make products. We are also building a computing ecosystem. Whether he’s adding IoT capabilities to an existing product or building smart devices from scratch, here’s what you need to know about designing, building, and deploying IoT products.
Four Elements of IoT Product Design
By definition, IoT products connect to networks. Share data and leverage that data. They consist not only of products, but also of user platforms, backend data infrastructure and connectivity that create powerful new capabilities. This requires at least four areas of development and expertise in each.
So IoT product development is inherently interdisciplinary. Here are his four areas of development needed to bring an IoT device to market and the expertise he needs on his team.
“In short, IoT product development is inherently interdisciplinary.”
1. IoT hardware
This is a truism, because it is true. IoT hardware puts “things” into the “Internet of Things”. This is the physical product you sell.
Many of the principles of good product design apply to IoT hardware. You need to take a holistic, user-centric approach. You have to imagine how the user will interact with the device and build it for a pleasant experience. It must be designed with available manufacturing capacity within budget.
However, unlike non-connected devices, additional space must be planned for sensors, radios, and chipsets that enable data collection and transmission. IoT hardware engineers also need to consider security at every stage of the design process, including tamper-proof designs and chipsets with secure cryptography built-in. (these are crypto processor.)
Who will be responsible for designing the IoT hardware? IoT Hardware Engineer.
2.IoT software
IoT devices need some kind of software to work.
- IoT device firmware. Technically, firmware is different from software. This is the microcode that controls the basic functionality of the device (boot process, basic input/output system (BIOS), basic security, etc.).
- Software for embedded devices. IoT device software adds additional functionality, including important capabilities such as applying over-the-air (OTA) updates and effectively communicating with the broader IoT ecosystem.
- Web/mobile application software. Users interact with IoT data through platforms running on the web or mobile devices. These applications also need to be designed to complete the IoT product experience.
Each of these areas requires expertise and expertise in various programming languages and frameworks such as React, Ruby on Rails, Python, Elixir, Phoenix, Nerves, and more.
Engineers must learn these tools separately. In other words, creating an IoT device requires a full team of developers, each with their own specialties, working together.
Who is responsible for designing IoT software? Firmware engineers, software developers, app designers, web developers.
3. Connectivity solution
Connectivity is at the core of IoT capabilities. Early in the IoT development process, you need to establish the connectivity and networking technologies your product will use. There are many options, from Bluetooth to Wi-Fi to cellular Low Power Wide Area Network (LPWAN) systems.
You don’t have to pick just one, but your choice of connectivity technology will dictate which radios and chipsets you include in your device.
Who is responsible for connectivity solutions for IoT products? Network engineers and connectivity providers.
4. Data infrastructure
IoT products can only collect, process, and transmit data. The backend data infrastructure is responsible for turning that data into insights. A data scientist can help you make decisions about: how It is necessary not only to build IoT products, but also to guide the process of building the systems that drive the IoT ecosystem.
Here are some areas of expertise that design teams need in the data department.
- database architecture
- data engineering
- cloud development
- Machine learning and AI
Who is responsible for data development for IoT projects? Data scientists, cloud developers, and often AI engineers.
As you can see, IoT product development requires diverse skills and a team that fits. All these experts must work together to design effective IoT products. Fortunately, you don’t have to have all this expertise in-house to start manufacturing IoT devices. The right IoT development partner of his provides the team and strategy your company is missing, so you can focus on the customer experience.
Once you have a plan, the challenges, of course, are: Build and deploy your device.
Understand the IoT device deployment process
There are several competing methodologies for developing IoT products. Agile approach is recommended. More on this later. However, regardless of the development method, all his IoT product deployments follow a few key steps. Assuming the design and planning are in place, this includes:
- prototyping. The purpose of the prototype is to check if the product works as expected. A fully engineered model of hardware is not required. There are multiple prototyping platforms you can use instead. At this stage, we develop a prototype and connect it to the network.
- under test. Laboratory testing can’t tell you everything about how a product actually behaves, but it’s a necessary first step. Connect your prototype to a network, see how it sends and receives data, and see how it responds to different situations that may arise after deployment.
- Initial product. IoT product development is a series of small steps. The first production should not be for the market. Instead, manufacture a small number of devices based on your design. Distribute it to beta testers. This real-world test introduces many problems, but gives you the opportunity to fix them before going into large-scale manufacturing.
- Expansion of production. Say you manufacture 100 devices for beta testing. If we can fix the problem, we can increase production to 1,000 devices. Get feedback from testers and early adopters before you move forward, and eventually move to market.
Admittedly, this list is an oversimplification. As mentioned earlier, IoT projects tend to be more successful when developed through an Agile framework. Agile methodology divides the development process into small iterative phases, each with a minimal viable product. Over time, these will be incorporated into successful deployments.
