NT has been operating for years in the internal communication sector, designing and building specific applications to improve mobility and safety in the workplace. NT's modern communication systems are aimed at users for whom communication does not boil down to simple telephone conversation. These systems allow, in fact, the integrated management of voice, messaging and security. The main users of NT systems include hospitals and rest homes, small and large companies, hotels and shopping centers. For each of these realities, customized solutions are developed that have as their common denominator the ability to connect to each other, even wirelessly: people, machines, computers and entire systems.
