Channel characterization for indoor environment at 17 GHz for 5G communications

The increasing demand for the extremely-high capacity and connectivity in wireless communication systems has motivated the researchers to explore the fifth-generation (5G) mobile communication. Owing to the wide bandwidth demand to increase the capacity, current spectrum bands below 6 GHz allocated for cellular mobile communication are congested and insufficient to support the services envisioned for 5G. Therefore, extensive on-going studies are investigating the feasibility to implement 5G systems at frequency above 6 GHz. In this paper, the propagation path loss at 17 GHz in indoor environment is characterized through series of continuous-wave channel measurements. Measurement results in typical Malaysian indoor propagation environment for both line-of-sight (LOS) and non-line-of-sight (NLOS) scenarios are presented.
