  The reconfigurable intelligent surface (RIS) technology is a potential
solution to enhance network capacity and coverage without significant
investment into additional infrastructure in 6G networks. This work highlights
the interest of the mobile communication industry on RIS, and discusses the
development of liquid crystal-based RIS for improved energy efficiency and
coverage in the millimeter-wave band. Furthermore, the paper discusses
perspectives and insights from an industry R\&D point of view, addressing
relevant use cases, technical requirements, implementation challenges, and
practical considerations for RIS deployment optimization in the context of 6G
networks.
