  Intelligent surface (IS) is envisioned as a promising technology for the
sixth-generation (6G) wireless networks, which can effectively reconfigure the
wireless propagation environment via dynamically controllable signal
reflection/transmission. In particular, integrating passive intelligent surface
(IS) into the base station (BS) is a novel solution to enhance the wireless
network throughput and coverage both cost-effectively and energyefficiently. In
this article, we provide an overview of IS-integrated BSs for wireless
networks, including their motivations, practical architectures, and main design
issues. Moreover, numerical results are presented to compare the performance of
different IS-integrated BS architectures as well as the conventional BS without
IS. Finally, promising directions are pointed out to stimulate future research
on IS-BS/terminal integration in wireless networks.
