Millimeter-wave (mmWave) technology has been well studied for both outdoor long-distance transmission and indoor short-range communication. In the recently emerging fiber-to-the-room (FTTR) architecture in the home network of the fifth generation fixed networks (F5G), mmWave technology can be cascaded well to a new optical network terminal in the room to enable extremely high data rate communication (i.e., >10 Gb/s). In the FTTR+mmWave scenario, the rapid degradation of the mmWave signal in long-distance transmission and the significant loss against wall penetration are no longer the bottlenecks for real application. Moreover, the surrounding walls of every room provide excellent isolation to avoid interference and guarantee security. This paper provides insights and analysis for the new FTTR+mmWave architecture to improve the customer experience in future broadband services such as immersive audiovisual videos.

毫米波（mmWave）技术已针对室外长距离传输和室内短距离通信进行了深入研究。在第五代固定网络（F5G）的家庭网络中最近出现的光纤到房间（FTTR）架构中，mmWave技术可以很好地级联到房间中的新光网络终端，以实现极高的数据速率通信（即> 10 Gb / s）。在FTTR + mmWave场景中，长距离传输中mmWave信号的快速衰减以及对壁穿透的重大损失不再是实际应用的瓶颈。此外，每个房间的围墙都具有出色的隔离性，可以避免干扰并确保安全。
