1 IoT – Connecting Everything, A Trillion Dollar Market
The Internet of Things (IoT) is the core technology for connecting everything. It endows objects with perception, control, and decision-making capabilities, driving various life scenarios towards continuous intelligent development. The main application areas of IoT include smart homes, vehicle networking, public services, smart agriculture, smart logistics, and smart industry, integrating previously isolated terminals into a network system, which can also create a large number of new application models and business models.Many IoT business models are linked to the number of connections, for example, charging based on the shipment of sensors and network modules in the perception and transmission layers; charging based on the number of connections in the platform layer; generating economic benefits in the application layer based on user scale, etc. GSMA predicts that by 2025, the number of global IoT device connections will reach 25.1 billion, and the global IoT market size will reach 1.1 trillion USD.
2 Perception Layer – The Hub of Physical Perception
Sensors are the starting point for connecting objects, serving as the basic hub that converts received physical perceptions into electrical signals. After decades of development, sensor technology can now collect and convert most physical state information in various scenarios into electrical signals that electronic information systems can process. Information such as temperature, humidity, pressure (weight), atmospheric pressure (tire pressure), light intensity, gas composition, fingerprints, facial recognition, speed, and displacement can all be collected through sensors. These sensing functions closely cooperate with downstream scenarios such as smart homes, logistics, vehicle safety monitoring, energy conservation and environmental protection, and security, forming a rich array of application models.The core of controlling and implementing IoT terminal functions is the MCU chip. The MCU, also known as a microcontroller, consists of a CPU, memory, various ports, etc., and is the core component of intelligent control, which can be simply understood as a miniature computer. The information collected by the sensor, commands input through interfaces (buttons, APP remote control, etc.), are analyzed and processed by the MCU, which then controls the execution mechanisms (motors, variable frequency compressors, audio devices, etc.) to realize the final functions of the IoT.
3 Transmission Layer – The Pipeline for Information Transfer
3.1. Mainly Wireless Transmission, Short and Long Distances Each ExcelThe transmission layer of IoT is mainly based on wireless transmission. Depending on the transmission distance, wireless transmission can be divided into local area networks (LAN) and wide area networks (LPWAN). Local area networks include well-known technologies such as Bluetooth and WiFi, characterized by relatively short communication distances, generally within 200 meters, suitable for indoor and low mobility scenarios (smart homes, smart warehouses, etc.). Wide area networks include NB-IoT, Sigfox, etc., characterized by a large communication range, which can exceed 15 km, suitable for large-scale, mobile scenarios (vehicle networking, logistics tracking, asset positioning, etc.).3.2. More Low-Speed Scenarios, High-Speed Value is HigherAccording to the different transmission rates, IoT services can be divided into high-speed, medium-speed, and low-speed services. High-speed services mainly use 3G, 4G, and WiFi technologies, applicable to scenarios such as video surveillance and in-vehicle navigation; medium-speed services mainly use Bluetooth, eMTC, etc., applicable to high-frequency usage scenarios such as smart homes and storage lockers; low-speed services, namely LPWAN (Low Power Wide Area Network), mainly use NB-IoT, LoRa, Sigfox, and ZigBee technologies, applicable to low-frequency usage scenarios such as smart parking and remote meter reading.About 60% of the global IoT market belongs to low-speed services, which require capabilities to support massive connection numbers, low terminal costs, low terminal power consumption, and strong coverage. Due to their own development and cost issues, various enterprises are moving towards low-cost, low-power directions. In the low-speed domain, China mainly focuses on developing NB-IoT (Narrowband IoT).3.3. The Core of the Transmission Layer: IoT ModulesIn the actual implementation of the industry chain, due to the complex standards, patents, and radio frequency technologies involved in wireless transmission, professional manufacturers generally produce IoT modules that integrate the overall functions related to wireless data transmission. Downstream manufacturers of home appliances can quickly achieve network connectivity after installing and debugging the IoT modules.IoT modules are modular components that integrate chips, memory, and other electronic devices on a circuit board, serving as the basic hub for achieving device networking. Depending on the network standard, wireless modules can mainly be divided into 4G modules, 5G modules, NB-IoT modules, etc. Depending on the application scenario, wireless modules can also be divided into smart modules and automotive-grade modules.
4 Platform Layer – The Bridge for Application Realization
Billing, activation, application realization, backend data management, etc.Once the hardware has IoT capabilities, a platform is needed to realize the entire network and application. Platforms can be roughly divided into four types based on functional types, and many generalized platforms actually have multiple functions.1) CMP/DMP Management Platform: Management of device connections. For example, buying a robot vacuum cleaner, turning it on at home, activating it, binding it with a mobile APP, etc., are all realized through the management platform.2) AEP Application Enablement Platform: Many traditional companies (such as power strip factories) want to upgrade to IoT remote-controlled power strips but lack the corresponding technical personnel; they can pay to use the AEP platform, which aggregates many IoT solutions. The power strip factory can set product parameters (how many sockets), functional modules (mobile control switch, timed switch, etc.) on the platform to directly generate the required IoT functionality.3) BAP Business Analysis Platform: The IoT collects a large amount of user data, and there are specialized platforms to analyze user data. Through big data, the functionality of devices can be made smarter, and customized marketing can also be done by analyzing user habits, etc. (for example, if a smart lock used by the elderly does not open the door all day, it can alert family members to check if they have fallen).

Industrial Software – CAX Carries the Design and Manufacturing of Various Industrial Products in IoTCAX Field: CAX consists of CAD, CAM, and CAE, which are core components of R&D design. In simple terms, CAD is software that replaces manual drawing to design the structure and appearance of products; CAM is software that simulates the running trajectories of tools during the production process of components and products; CAE, also known as simulation, is software that simulates the stress, heat, and other conditions of products in various scenarios to test whether the designed product meets relevant mechanical and electromagnetic standards. CAX integrates CAD, CAM, and CAE to simulate the entire industrial design and manufacturing process.Relationship with IoT: All industrial products, from large airplanes, ships, and cars to small headphones, tablets, and mobile phones, require R&D design software for design. Without R&D design software, there would be no existence of various devices in IoT, so R&D design software can be said to be the ‘mother of industrial products’.5.3.2. The Launch of HarmonyOS Marks the Beginning of a New Decade of Innovation CycleHarmony: HarmonyOS is a next-generation operating system for the IoT era, aiming to achieve connectivity and intelligence for everything. In the future, it will gradually cover 1+8+N all-scenario terminal devices: ‘1’ represents smartphones, ‘8’ represents PCs, tablets, smartwatches, smart screens, AI speakers, secondary devices, AR/VR glasses, and in-car systems, while ‘N’ represents IoT ecological products, providing intelligent services for consumers in all aspects of life.
