On December 27, OPPO announced the latest technological progress in the four major areas of AI, performance, communication, and privacy security, including the first handset/hands-free dual-mode satellite call for smartphones, the first end-to-side application of 7 billion parameter large model, the debut of the tidal architecture and many other cutting-edge technologies. The new technology portfolio announced this time will fully land the next generation flagship product Find X7 series, setting a new technical benchmark for flagship phones in 2024, and bringing consumers a new standard of innovative flagship experience.
Released handset/hands-free dual-mode satellite calls, leading the evolution of satellite walkie-talkies to satellite mobile phones
OPPO launches Satellite antenna pattern control technology that will enable the innovative experience of handset/hands-free dual-mode satellite calling for the next generation flagship. This technology can dynamically regulate the radiation pattern of the satellite antenna, so that the antenna beam can be dynamically aligned with the satellite, and ensure that the user can maintain the connection and the state of communication with the satellite in both the handset and the hands-free posture.
OPPO Hardware Engineering Terminal antenna expert Lu Bao said: "We are very happy that through continuous research and accumulation, using a series of innovative technologies and patents, for the first time in the next generation flagship product to achieve the latest breakthrough in satellite antenna technology. With satellite communications technology and fully upgraded antennas, smart communications and near-field communications, we expect users to have a consistently reliable communication experience in all scenarios."
Traditional satellite communication mobile phones use a single antenna design, and cannot meet the needs of the transmission power in the head-hand state, and can only support the use of a hands-free mode, which will lead to problems such as unable to communicate clearly in severe weather environments such as strong winds. OPPO's new handset/hands-free dual-mode satellite call for the first time allows the mobile phone satellite call experience to evolve from the "satellite walkie-talkie mode" to the "satellite phone mode" that conforms to the user's intuition, helping users obtain more efficient communication efficiency in extreme environments.
