SOFTLINK operates in the European market as a technology integrator in the field of online measurement of energy, water, heat, etc. We develop and manufacture our own hardware for data transmission using various technologies - IoT SIGFOX or NarowBand, our own WACO 868 MHz. In the area of smart metering we also use the frequency 169 MHz, which is an unlicensed band intended for remote readings, widely used throughout the EU. For work with data, we supply SW solutions suitable for a wide range of customer needs - from the LDN (Local Distribution network) operator to shopping center or logistical parks.
