I. What is Internet of Things (IoT) application technology?
The Internet of Things (IoT) refers to a network concept that connects any object to the internet through information sensing devices such as RFID, infrared sensors, GPS, and laser scanners, via IoT domain names, enabling information exchange and communication to achieve intelligent identification, location, tracking, monitoring, and management. Ubiquitous networks, IoT, and sensor networks are sequentially related. Sensor networks focus on end-point connections between things, emphasizing the perception and collection of information from the physical world, and prioritizing efficient network distribution and aggregation; they also focus on low speed, high efficiency, and low power consumption. The IoT is a network oriented towards both things and people, encompassing various sensing units (sensors, RFID, etc.) and supporting one or more network communication methods to provide services and applications for the real world. Ubiquitous networks encompass and transcend the IoT, emphasizing the integration of multiple networks and technologies, exploring seamless connections between communication and services, and exploring new ways of communication and service between people.
II. How to choose the right IoT module?
The Internet of Things (IoT) is revolutionizing and improving the way we work and live, but this can only be achieved through ubiquitous, flexible, and long-term wireless connectivity. At its core is a small device called an IoT module, responsible for connecting virtually anything to a wireless network. IoT modules utilize a wide range of wireless technology standards, offering a variety of features that can significantly impact the success of IoT applications. So, how do you choose the right IoT module for your solution? Let's start with the basics.
(I) What is an Internet of Things (IoT) module?
IoT modules are small electronic devices embedded in objects, machines, and devices that connect to wireless networks to send and receive data. Sometimes referred to as "radio chips," IoT modules contain the same technology and data circuitry found in mobile phones, but lack features such as displays or keyboards. Another key difference between IoT modules and their counterparts is that they provide constant connectivity. This is because IoT applications require data to be sent automatically in real time without anyone clicking a send button. Furthermore, they are designed for extreme durability and lifespan, requiring continuous operation for ten years or more to prove the technology's commercial viability and cost-effectiveness.
(ii) Why is durability so important in IoT modules?
Unlike consumer devices, which are typically carried by end-users and used in controlled environments, IoT devices are often deployed in extreme environments and remote locations, such as seawater in containers or port management solutions. IoT environments can be extremely harsh, with extreme temperatures, vibrations, and humidity levels. Furthermore, they are often located in remote, hard-to-reach locations, making it prohibitively expensive to send technicians for repairs. IoT modules must be rugged and durable, providing reliable connectivity without service interruptions, regardless of location or wireless network used.
(III) Designing IoT solutions or connected prefabricated solutions from scratch?
IoT solutions are designed to meet unique customer needs, with each use case having specific connectivity requirements. For example, a large project connecting tens of thousands of endpoints globally is significantly different from one connecting only a few hundred devices. Large projects with complex infrastructures typically require custom connectivity solutions tailored to specific needs and integrating IoT modules. However, smaller projects can leverage pre-designed and pre-certified IoT endpoints, providing plug-and-play connectivity and saving time and development costs.
(iv) Which wireless technology standard is the best?
IoT modules and IoT devices utilize a variety of wireless technologies to maintain seamless connectivity. These include 5G, 4G, and 3G cellular solutions for high-bandwidth applications such as automotive connectivity; low-power, wide-area (LPWAN) solutions such as MTC (Machine-Type Communication); Bluetooth and LoRa for smart road systems; and smart city and enterprise applications. Selecting IoT devices with the optimal features, bandwidth, and price point for each use case is a crucial step in achieving business and revenue goals. These choices may initially seem daunting, but experienced OEMs and developers can help solve the best-match problem for each customer through connectivity considerations.
