Abstract: High data rate communication is gaining attention to comply user demand, especially in an indoor environment. In a future fifth generation (5G) communications system, the need for broader spectrum bandwidth motivates the researcher to explore new carrier frequency range from centimetre-wave (cm-Wave) to millimetre-wave (mm-Wave). The paper presents the characterization of penetration loss measurement and modeling for four interior materials typically used in Malaysia building construction, such as concrete, clear glass, tinted glass, and drywall. The measurement campaigns were conducted at 6.5 GHz, 10.2 GHz, 15 GHz, 20 GHz, 28 GHz and 38 GHz in an office environment in Universiti Teknologi Malaysia (UTM- Kuala Lumpur) campus. From the measurements campaign, the result of penetration losses is extracted and modeled. As consequences, it specifies Malaysia building is an environmental friendly for 5G communication due to low attenuation observed compared to existing studies conducted in temperate regions countries. Moreover, the unique characteristic of 15 GHz and 20 GHz distinguished the most potential frequencies for building penetration, especially in Malaysia building environment.
