IOT - choosing the right technology (part I)

In recent years, the number of IoT devices and technologies has skyrocketed, and this trend shows no signs of slowing down. As the IoT landscape continues to expand exponentially, choosing the right IoT solution has become a critical challenge for businesses and developers alike.

When embarking on the creation of an IoT solution, it is essential to consider the requirements from the perspective of the end device. By asking a series of upfront questions, you can gain valuable insights that will shape the direction of your IoT implementation:

Power Source

Determine whether the device will be powered by a direct power source or operate on standalone batteries. If batteries are utilized, it is crucial to establish the desired autonomy. Should the device be recharged weekly, monthly, or should it have an extended lifespan of several years (e.g., 2, 5, or 10 years)? This decision will influence the device's power management capabilities and overall maintenance requirements.

Connectivity Requirements

Understand the type of connectivity required for your IoT solution. Does the device need direct connectivity to the internet, or can it leverage a gateway or companion device for communication? This consideration will impact factors such as network coverage, data transmission protocols, and potential limitations or dependencies.

Data Transmission

Evaluate how frequently the device needs to send data and estimate the size of each transmission. This information will help determine the appropriate communication technology and bandwidth requirements. Understanding data transmission patterns is crucial for optimizing network resources, managing costs, and ensuring efficient data transfer.

Environment

Determine whether the device will be deployed in an indoor or outdoor setting. This knowledge is essential for selecting components that can withstand varying environmental conditions, such as temperature, humidity, and potential exposure to dust or water.

Location Accuracy

Assess the importance of precise device location for your IoT solution. If location accuracy is crucial, define the required level of precision and specify the scenarios in which it is necessary (indoor, outdoor, or both). This consideration is vital for applications such as asset tracking, geolocation services, or environmental monitoring.

Addressing these questions is fundamental to gain a comprehensive understanding of your IoT solution's requirements and ensure a well-aligned design approach.

Let's first dive into the area of communication technologies employed in IoT, as they have a profound impact on several aspects, including power consumption, scalability, security, and the overall system architecture.

Short range connectivity:

When it comes to short-range connectivity, two perspectives emerge: Wi-Fi and traditional low-power protocols.

Wi-Fi has experienced significant advancements in recent years, particularly in terms of connectivity speed. It has become the de-facto standard for replacing Ethernet in homes and offices, with approximately 3-4 billion Wi-Fi devices being produced each year. While Wi-Fi is not inherently designed for power efficiency, there have been notable improvements. For IoT applications, Wi-Fi is a suitable option if the devices can be continuously connected to a power source. Annually, around 800 million IoT devices are connected through Wi-Fi. Furthermore, the Wi-Fi 6 standard introduces Low Power Wi-Fi capabilities, accommodating approximately 200 million low-power devices per year.

In the realm of "traditional" low-power protocols, there have been significant advancements. Notably, the emergence of the Matter standard, a collaboration among industry giants such as Google, Apple, and Samsung. Matter operates on top of Thread and Wi-Fi protocols and offers seamless configuration and automation capabilities. Thread and Bluetooth Low Energy (BLE) have also evolved, providing improved coverage and efficiency for short-range IoT communication.

Long range options

For long-range IoT solutions, Low Power Wide Area Networks (LPWAN) come into play. These networks enable communication over several kilometers while maintaining low power consumption. However, they have a tradeoff in terms of transmitting small amounts of data, which aligns well with the requirements of IoT sensor networks.

In the realm of regulated or closed frequencies, mobile providers have extended their traditional offerings with technologies like nb-IoT (Narrowband IoT) or the latest evolutions of 5G. These technologies allow for resource allocation based on traffic patterns, specifically catering to IoT applications characterized by a low number of packets but frequent transmissions.

On the other hand, for non-regulated frequencies, LoRaWAN stands out as one of the most well-known technologies. LoRaWAN is an open, long-range communication technology that can be implemented by individuals or companies similar to Wi-Fi. It specifically focuses on use cases requiring long-range, low-transmission communication.
