The portion of the Industrial, Scientific and Medical (ISM) unlicensed frequency bands below 1 GHz is widely used to implement wireless communication networks in industrial process control, home and building automation and automatic meter reading applications.

Users in this band can freely select the characteristics of the physical layer – transmitted power, modulation scheme, data rate and channel bandwidth – and network topology – either star or mesh – as well as use any proprietary protocol. This help users define an optimized solution to meet performance and system efficiency requirements for the real-time monitoring and control of thousands of nodes in a large industrial process control networks. This portion of the RF spectrum is then particularly suited to enable Internet-of-Things and smart city networks including street lighting, smart parking and traffic control systems.

ST offers a range of products including RF transceivers, baluns and STM32 microcontrollers as well as hardware and software evaluation and development tools to help design and deploy cost-effective network solutions.
