Thailand’s telecommunications operator Advanced Info Service Public Company Limited (AIS) and ZTE Corporation have accomplished the world’s first dynamic RIS (Reconfigurable Intelligent Surface) trial in a mmWave network at the AZ centre in Bangkok. According to the statement, this collaboration explores new possibilities in mmWave communication, offering a low-cost, low-carbon solution for deploying mmWave networks at scale.

Dynamic RIS Technology
RIS, or Reconfigurable Intelligent Surface, is a multi-antenna technology that uses electromagnetic metamaterials to intelligently reflect or transmit base station signals. It is said to extend base station coverage, improve coverage quality, and does so at a low cost with minimal carbon emissions.
ZTE’s dynamic RIS technology incorporates dynamic functionality for beam sweeping and user tracking, enhancing base station coverage even for users on the move, said the statement.

Performance Results
During the trial, dynamic RIS technology was implemented in the AIS millimeter-wave network with a 400 MHz bandwidth. This implementation enhanced millimetre-wave signal coverage, enabling users to achieve a consistent peak downlink rate of over 1.6 Gbps and an uplink peak rate of over 260 Mbps, even in a large office room of over 400 square meters.
According to ZTE, this performance was more than three times better than what could be achieved without RIS in obstructed scenarios.
