The Internet of Things (IoT) is revolutionizing the way we interact with the world around us. IoT devices are becoming an integral part of day to day processes, from healthcare to industrial applications. However, to fully tap into the potential of IoT's power, you’ll need make sure your backend is robust and secure.

This post will guide you through best practices for setting up your IoT backend, with a focus on connectivity.

What is an IoT backend?

IoT backend refers to the server side of an IoT system. It’s where the data from various IoT devices is gathered, processed, stored, and managed. It's an essential component of an IoT system, and it encompasses multiple functions, including:

  • Data storage and management
  • Device management
  • Data processing and analysis
  • Security
  • Integration and interoperability

By setting up an effective IoT backend, organizations can better handle the complexities of an IoT system, making it easier to manage and gain valuable insights from the vast amounts of data generated by their connected devices.

Connectivity: The heart of your IoT backend

Connectivity is the lifeblood of any IoT system. It allows devices to communicate with each other and the backend. Several connectivity options are available for IoT devices, including Wi-Fi, cellular, and satellite. However, each option has its own advantages and disadvantages. The choice largely depends on your IoT system’s specific requirements.

Cellular connectivity

Cellular connectivity is a popular choice for IoT systems due to its comprehensive coverage and reliable connection. It's beneficial for IoT devices that are mobile or located in remote areas.

Private LTE networks

Private LTE networks are an excellent option for IoT systems that require a high level of security. These networks provide a dedicated and secure connection for your IoT devices, isolating them from the vulnerabilities of the public internet.

Wi-Fi connectivity

Wi-Fi is a prevalent and affordable option for IoT systems in fixed locations like homes or offices. Its capacity for high data transfer rates is a strength. Yet, its range is limited, typically up to 100 meters and its reliance on unlicensed spectrum can result in interference.

Satellite connectivity

Satellite connectivity is optimal for remote IoT systems due to its global reach. However, it comes with high deployment costs, potential latency issues, and increased power consumption.

The choice of IoT connectivity—be it cellular, private LTE, Wi-Fi, or satellite—should be guided by your system's specific needs. Each option offers unique benefits and limitations, so choose wisely to ensure an efficient, reliable IoT system.

IoT connectivity best practices

When setting up your IoT backend, there are a few best practices you should keep in mind:

Choose the lowest power network that will do the job

Power consumption will always be at odds with range and throughput. The more range and throughput you need, the more power your IoT devices require. Since power is one of the things you’re paying for when you operate an IoT network, a lower-power network will be more cost-efficient.

Plan for device maintenance and updates

Every IoT device on your network represents an access point to that network. One of the most common causes of security breaches is IoT devices with outdated software. It’s easy to forget to update the software and firmware on your IoT devices, especially when they’re small things like sensors. Before setting up your network, establish policies and procedures for updating and maintaining your IoT devices.

Never use default passwords and credentials

Most IoT devices ship with default access credentials. These default credentials often get used because people don’t think to change them or don’t even realize there’s a way to access the device with a username and password. Make sure you check and secure every IoT device before deploying it on your IoT network.

Build a strong IoT backend with the right partner

Setting up an IoT backend can be a complex task, but with the right partner, it doesn't have to be. By following the best practices outlined in this article, you can set up a robust and secure IoT backend that can handle the demands of your IoT system. However, the stakes of not doing things right can be high. A poorly set up IoT backend can lead to connectivity issues, security vulnerabilities, and scalability problems.
