+## SIG group work objectives and scope
+
+### work goals
+This SIG focuses on the management of cellular network devices in smart cities. Based on the OpenHarmony architecture, it develops basic capability components such as cloud components, device channel cloud components, device security and industry application components, enriches the OpenHarmony architecture, and promotes the formation of industry standards and specifications; Combine the characteristics of OpenHarmony's intelligent connectivity with the smart city cellular network device application scenarios to promote the prosperity of the industry's Internet of things products ecological .
+
+### work scope
+Complementary capabilities: complement key capabilities in industrial applications and expand the application scenarios of the Internet of things cellular devices;
+
+Ecological construction: cooperate with ecological partners in the industry, professional institutes, universities and developers, link with the government, and jointly improve OpenHarmony;
+
+Establish standards: formulate the application specifications and industrial application standards for the cellular IOT network, and introduce the OpenHarmony characteristic capabilities into the specifications and standards;
+
+Extensive replication: benchmarking projects are first tried, and OpenHarmony application scenarios are jointly innovated with ecological partners to drive the development of OpenHarmony industry with demonstration effect.
