ZTE Corporation, a leading global provider of telecommunications equipment and network solutions, has successfully partnered with Thailand’s leading telecommunications operator AIS to accomplish the world’s first dynamic Reconfigurable Intelligent Surface (RIS) trial in an mmWave network at the AZ center in Bangkok.
This collaboration explores new possibilities in the field of millimeter-wave communication, offering a low-cost, low-carbon solution for deploying millimeter-wave networks at scale. RIS is an innovative multi-antenna technology that utilizes electromagnetic metamaterials. RIS enables the extension of base station coverage by intelligently reflecting or transmitting base station signals, resulting in improved coverage at a low cost and with low carbon emissions. By incorporating dynamic functionality, ZTE’s dynamic RIS technology achieves beam sweeping and user tracking, effectively enhancing the coverage range of base stations and ensuring an optimal user experience, even when the user is on the move.
During the trial, ZTE adopted the dynamic RIS product in the AIS millimeter-wave network with a 400MHz bandwidth. This implementation led to a substantial enhancement in millimeter-wave signal coverage. Users were able to consistently maintain a peak downlink rate of over 1.6G bps and an uplink peak rate of over 260 Mbps while moving within an office room larger than 400 square meters.
Through the collaboration between ZTE and AIS, dynamic RIS technology has been successfully implemented in millimeter-wave networks. This technology effectively overcomes propagation obstacles and enhances coverage range and transmission speed. The implementation of this technology is predicted to have significant applications in future smart cities, industrial IoT, and other domains.
