Q-band Millimeter Wave Communication: Enabling 10 Gb/s Home Network in Fiber-to- The-Room Scenario

Millimeter wave (mmWave) technologies have been well studied in both long range outdoor communication and short range indoor communication. Owing to the high propagation loss and blockage of walls, the coverage of mm Wave for indoor scenario is greatly limited. In these two years, with the evolution of the fifth generation fixed network (F5G), the deployment of Fiber-to- The-Room (FTTR) provides a powerful tool to improve the coverage of indoor mmWave communication. Based on the fiber connection between rooms, it is possible to supply extremely high data rate backhaul channels for mmWave communication in every room by FTTR. Furthermore, the large attenuation of walls eliminates the interference between wireless communication systems in different rooms, thus making it possible to build a non-interference home network which significantly outperforms traditional WiFi mesh networks. To verify the performance of Q-band mmWave communication in indoor scenarios, a prototype was designed and data rate higher than 10 Gb/s could be achieved when 4×4 MIMO technology is adopted. To the best of our knowledge, this is the first Q-band communication prototype achieved data rate higher than 10 Gb/s.
