Overview of the IoT Industry Chain and Key Players

IoT development requires first establishing connectivity before discussing value‑added applications.

1. Major players entering the IoT market

Intel: released Edison wearable/IoT micro‑system‑on‑chip in 2014 and Curie chip in 2015 with low‑power Bluetooth and motion sensors.

Google: launched Project IoT and the Brillo operating system (derived from Android) in 2015, supporting ARM, x86 and MIPS hardware.

Cisco: acquired Jasper in 2016 for $1.4 billion to strengthen the IoT ecosystem.

SoftBank: planned a $31 billion acquisition of ARM to secure IoT chip patents.

Huawei: promoted NB‑IoT standards, released LiteOS and NB‑IoT solutions, and built the OceanConnect ecosystem.

Baidu: launched Baidu IoT in 2015, collaborating with ARM, MTK, TI and others.

Alibaba: issued an IoT strategy in 2016 integrating Alibaba Cloud, Alibaba Smart, and YunOS; co‑launched the MICO OS in 2014.

Tencent: introduced the QQ IoT Open Platform in 2014, offering account, messaging and device‑link capabilities.

China Mobile: created IoT and vehicle‑IoT subsidiaries, built dedicated networks, SIM services and development platforms.

2. The IoT industry chain consists of eight major segments

Chip suppliers, sensor suppliers, wireless module (including antenna) manufacturers, network operators (including SIM providers), platform service providers, system and software developers, smart‑hardware manufacturers, and system‑integration/application service providers.

3. IoT chip suppliers – the "brain" of IoT

Low‑power, high‑reliability semiconductor chips are essential for almost every IoT link. They include chips embedded in sensors and modules as well as system‑on‑chip (SoC) or MCU processors that act as the device’s brain. International giants: ARM, Intel, Qualcomm, MediaTek, Freescale, Texas Instruments, STMicroelectronics, etc. Domestic Chinese vendors: Huawei HiSilicon, Spreadtrum, Beijing Junzheng, Allwinner, Beidou Xingtong, Tongfu Microelectronics, Huada, Liyuan, Runxin, etc.

4. Sensor suppliers – the "senses" of IoT

Sensors detect and convert physical, chemical or biological phenomena into electrical signals, covering identity, motion, location, temperature, humidity, light, sound, and more. Major global suppliers include Bosch, STMicroelectronics, Texas Instruments, Honeywell, Freescale, Infineon, Philips, and others. In China, foreign firms hold about 70 % of the market; notable local players are Hanwei Electronics, Goer Audio, Gaode Infrared, Nawei Technology, Huagong Technology, and Yuanwang Valley.

5. Wireless module manufacturers – the "key" for connectivity and positioning

Wireless modules enable network access and positioning. They are divided into communication modules (Wi‑Fi, Bluetooth, ZigBee, 2/3/4G, NB‑IoT, LoRa, SigFox) and positioning modules. Global leaders: Telit, Sierra Wireless. Chinese providers include Huawei, ZTE, Huanxun, Quectel, Xinwei, China Mobile IoT, Shanghai Qingke, Li Erda, Bo Pengfa, Xinweitong, Shuo Beide, and Beidou Xingtong.

6. Network operators – the "channel" of IoT

Network operators supply the communication infrastructure (cellular, LAN, private networks) and related components such as SIM cards. Key domestic SIM manufacturers: Dongxin Peace, Hengbao, Tianyu Information.

7. Platform service providers – managing IoT resources effectively

Platform providers offer device management, data collection, analytics, and application enablement services.

8. System and software developers – the "arteries" of IoT

Major OS providers include Google, Microsoft, Apple, Huawei and Alibaba. Application development is still nascent, focusing on automotive, smart home and endpoint security (e.g., Shenglu Communications, Haier, VenusTech).

9. Smart‑hardware manufacturers – the "terminal" of IoT

Smart hardware integrates sensors and communication modules to become IoT endpoints. It can be B2B (smart meters, industrial monitors, vehicle‑mounted units) or B2C (wearables, smart home devices). Representative Chinese vendors: Sanchuan Smart, Xintian Technology, Hanwei Electronics.

10. System integration and application service providers – the "implementers" of IoT solutions

These firms deliver end‑to‑end IoT projects, integrating hardware, connectivity, platforms and vertical applications.
