¿µ¹®³»¿ë¿ä¾à In order to efficiently support various application services with different characteristics through a single network, a differentiated network connection control technology according to the characteristics of each service is required.
This standard defines priority-based competitive channel access technology and reservation-based contention-free channel access technology for providing the differentiated network connection control. In addition, it defines the functions and interfaces of a device, RF gateway, and network controller constituting a LPWAN based on differentiated channel access.
