Abstract. The paper discusses the principles of building digital cellular networks of the McWiLL standard to ensure network interaction between the components of an automated environmental monitoring system. The analysis of the construction of the core of the McWiLL network, the interaction of individual modules of the core of the McWiLL network was carried out, their main functions were described. The main parameters to be configured for the base station of the digital cellular communication system of the McWiLL standard are given. A description of the software and hardware implementation of a wireless communication network using the concept of virtualization of network functions is given. A test stand for digital cellular communications for an automated environmental monitoring system has been developed, and the main parameters of the communication network have been measured. The obtained data rates meet the requirements of AEMS and are 400 kbps in the downlink and 630 kbps in the uplink with a 2:6 time interval configuration, which allows for periodic data collection from connected sensors.
Keywords: automated monitoring, McWiLL network core, virtualization of network functions.
