ABSTRACT
The article reports on the launching of Medius, a platform that secures the data from "Sentry" network management system of Mixed Signals Inc. in the U.S. This program can deal and consolidate information for up to 15 Sentrys. Moreover, it can cover bandwidth at the Quadrature Amplitude Modulation level.
