Teco Company has developed a family of wireless modules, remote working in the radio network RFox. Bandwidth is dedicated to operating the equipment installed in ISM / Industrial, Scientific, Medical / environments occupying the frequency channel  868.3  -50kHz. Wireless communications in the radio network RFox takes place in the master-slave mode, one master module supports up to 64 Slave peripherals. The scope of propagation is approximately 30m. in the halls and construction of buildings with heavy walls and ceilings, which actively suppress wireless communication, to around 50 m. infrastructure in facilities with lighter construction and about 100 or even 150m. in the open air with good visibility of communicating modules. Applications eliminate the need for wired networks, which is particularly helpful for technological lines with a large number of sensors and actuators and in case of distributed installation of automation systems for the construction of infrastructure /HVACR/, especially in historic buildings.
