**Abstract:** With the increasing adoption of NB-IoT chips, a growing number of companies involved in this technology have emerged. This article highlights several listed companies that are actively engaged in the NB-IoT ecosystem, focusing on their innovations, applications, and contributions to the Internet of Things (IoT) industry.
**NB-IoT Related Listed Company – China Telecom**
At the 2017 Tianyi Intelligent Eco Expo, China Telecom announced its plan to achieve full network commercialization of VoLTE by 2018. Alongside this, technologies like NB-IoT and eMTC were also expected to reach commercial deployment. During the event, China Telecom showcased its end-to-end IoT solutions, from M-IoT chip modules to platform applications, covering smart cities, vertical industries, and personal consumption sectors. The company formed a comprehensive M-IoT ecosystem.
At the Tianyi IoT Industry Alliance Summit Forum, China Telecom introduced 12 IoT warehousing modules, including six NB-IoT modules and six Cat.1 modules. The alliance’s membership has grown significantly, from 95 to 177 members. Its solution library covers over 40 IoT scenarios, ranging from smart cities and transportation to industrial energy and healthcare.
Several alliance members have already implemented NB-IoT-based projects. For example, Huizhong Instrument completed a pilot for NB-IoT smart water meters in Shunde, while Zhejiang Jinka expanded its smart gas meter pilot to over 1,000 units across three locations. Additionally, Ningxia Auto deployed NB-IoT cow monitoring systems in four provinces, including Heilongjiang, Inner Mongolia, and Xinjiang.
Shen Shaoai, Deputy General Manager of China Telecom’s Technology Department, emphasized that the company's NB-IoT network based on 800M spectrum has a global advantage. He noted that IoT applications are fragmented, with a long-tail effect, making it difficult for a single technology to meet all needs. NB-IoT and eMTC, developed under 3GPP, were tailored for different IoT use cases.
**NB-IoT Related Listed Company – China Mobile**
China Mobile recently established the OneNET IoT Alliance, collaborating with MediaTek to launch an NB-IoT universal module based on the MT2625 chip. This module integrates China Mobile’s “eSIM card,†a software-based alternative to traditional SIM cards. As part of a smartphone’s internal functions, eSIM eliminates the need for a physical card, enhancing convenience and security.
One practical example is the shared bicycle smart lock. A single battery can last over six years, and users can track the bike’s location in real time. If the bike is moved, tampered with, or attacked, the system immediately sends an alert with the location to ensure safety. Unlocking takes only 2–3 seconds, supporting multiple methods such as app buttons, QR code scanning, or card swiping.
The Chinese government has been actively promoting IoT development. In June 2017, the Ministry of Industry and Information Technology issued a notice urging the accelerated deployment of NB-IoT networks. By the end of the year, 400,000 base stations were planned to be built, with the three major telecom operators leading the effort.
The IoT is being applied in public services, such as smart metering for water, electricity, and gas, public parking management, and environmental monitoring. These initiatives support the broader goal of smart city development. On the consumer side, IoT is used in smart homes, wearables, elderly care, pet tracking, and consumer electronics.
**NB-IoT Related Listed Company – Huawei Technologies Co., Ltd.**
In 2014, Huawei first proposed the narrowband technology NB-M2M, which later evolved into NB-IoT through collaboration with Qualcomm, Ericsson, and others. In June 2016, the NB-IoT core protocol was approved by 3GPP, marking its recognition as a global standard. It represents a significant advancement in both technological innovation and market demand.
Huawei is currently the largest NB-IoT chip manufacturer in China, offering a wide range of products, including wireless and fixed network chips, digital media solutions, and more. These have been successfully deployed in over 100 countries worldwide.
In the digital media sector, Huawei has launched SoC network monitoring chips, videophone solutions, DVB chips, and IPTV chips. The company also provides various communication modules, vehicle networking terminals, and IoT solutions, earning recognition for quality and innovation in both domestic and international markets.
