ZTE Satellite Terminal S60 Pro: Enabling All Smartphones to Make Satellite Calls and Send Satellite SMS. The ZTE S60 Pro utilizes advanced left-hand circularly polarized (LHCP) wave antennas. Compared to conventional linearly polarized antennas, these antennas offer approximately four times the alignment angle range with satellites, resulting in higher antenna gain, making it easier to accurately align with and quickly locate satellites. Equipped with an all-new domestically developed and self-researched chip, the S60 Pro integrates baseband and radio frequency (RF) functions into a single unit, showcasing independent innovation, high integration, exceptional reliability, and ultra-low power consumption. It supports voice rates of 2.4kbps, 1.2kbps, and 800bps, enabling clear phone calls even at signal levels as low as -125dBm, demonstrating its outstanding performance and stable signal reception. Designed for extreme environments, the product boasts an IP68 rating, the highest level of dust and water resistance, ensuring reliable operation in temperatures ranging from -40°C to +70°C. Furthermore, the S60 Pro includes a location check-in feature and a one-button SOS emergency call function, providing users with comprehensive safety and security. The entire device is made of 95% recyclable plastic, with a metal material used for the hanging strap at the bottom. Dimensions of the whole device: 101.946320 (mm).
