Guangzhou Jixiang Technology

Guangzhou Jixiang Technology, also known as Techphant, is a high-tech enterprise established in December 2018 as a result of the commercialization of scientific and technological achievements from the Guangzhou Communications Research Institute. The company's legal representative is Xu Xin, who also serves as the founder and chairman. The co-founder, Vice President, and CTO is Dr. Zheng Rin, who started the venture at the age of 40 and leads the TPUNB project. Dr. Wenwen Kun serves as the Chief Engineer. The firm focuses on developing core technologies for the Internet of Things (IoT).

The core of Jixiang Technology's business is its independently developed TPUNB® (Techphant Ultra Narrow Band) wireless narrow-band communication system. This full-stack system, with 100% proprietary intellectual property rights, operates from the physical and link layers up to the platform layer, addressing a critical gap in China's IoT infrastructure, which has historically relied on foreign technologies like LoRa. The TPUNB technology is designed to provide wide-area coverage (3-5 km in cities, over 10 km in suburbs), support a massive number of concurrent connections, and offer high security and low-power operation, extending the battery life of sensor terminals. This technology is positioned as a key enabler for digital transformation across various sectors by providing a secure and domestically controlled communication foundation.

Jixiang Technology's business model revolves around providing comprehensive IoT solutions and equipment. The company serves a diverse client base across vertical industries by offering complete IoT communication solutions and project construction. Its business strategy focuses on two main areas: large-scale government and enterprise projects, and the energy sector, while also enabling a wide range of other industry applications. Key application scenarios include smart cities, smart parks, intelligent power systems, industrial IoT, smart security, and smart water management. For instance, in the energy sector, the company has developed smart gateway and monitoring systems for power distribution rooms to automate inspections and data collection. Recently, the company has expanded into the smart home market through strategic partnerships with home furnishing companies like Holike and Homi Technology to develop new applications and products.

The company's product portfolio includes chips, modules, and gateway products based on its TPUNB technology. A significant milestone was the development of the "Xiangxin No. 2" chip, with mass production anticipated. The firm has also developed a series of "Dianhong IoT" products, including various sensors that have passed technical appraisals and support smart power grid applications for major clients like Southern Power Grid. The company has received significant financial backing, completing a Series C funding round of nearly 200 million yuan in late 2023 and a subsequent C+ round of 106 million yuan in July 2025. These funds are allocated to continued core technology development and the commercialization of its TPUNB products.
