Network equipment suppliers in China The leading international suppliers of network equipment - Alcatel-Lucent, Cisco, Ericsson, Huawei, Nortel and Siemens - as well as the major international suppliers of portable phone sets - Ericsson, Motorola, Nokia, Samsung, and also Siemens - are well known in China.

Datang is the main TD-SCDMA manufacturer, and UTStarcom, the main PAS/PHS manufacturer. Huawei leads the SMS market and Great Wall stands out in the broadband sector. Other recognized Chinese equipment suppliers are Shanghai Bell (subsidiary of Nokia) and Zhongxing Telecommunications Equipment (ZTE).

More Chinese cities followed in 2005. There has been development of database software, interoperability consoles and data management systems. There has been an increasing use of Internet of Things (IoT) to install wireless intelligent fire, smoke and gas detection systems nationwide and China Mobile has installed over 100,000 NB-IoT intelligent fire alarm systems, including smoke, gas and temperature sensors, and
