Eartec Ultralite is a complete, wireless send/receive system operating in the DECT 1.8 GHz (1800 MHz) range. Eartec DECT intercom systems are free of charges and registration in most European countries, including Germany. DECT is a global standard for wireless, digital telephones and intercom communication, primarily used in Europe and the USA. Transmission on these frequencies in the 1.8 GHz range is not affected by other devices operating in the 2.4 GHz range (e.g., Wi-Fi, microwaves, etc.). Operating at 1.8 GHz provides uninterrupted and interference-free radio communication, and DECT encryption ensures the necessary security. No base station or relay station is required. Eartec systems operate directly from headset to headset. With a wide range of applications, these intercom systems have almost no limits and are the ideal solution for crane operators, maintenance personnel, machine operators, casinos, referees, theaters, TV and music studios, stage technicians, restaurants, industry, assembly companies, security services, electrical construction, sports and event companies, forestry, rallying, and many others.
