Wireless evolution has come a long way over the last 40 years, starting from a technology-centric all the way to a technology-transparent future, shifting the focus of innovation from components and radio transceiver technologies(e.g., MIMO) to resource allocation and interference management(e.g., CDMA, OFDMA) and to user-centric and device-driven communications, in the “internet of everything.” Wireless communications are expected to dominate everything, everywhere, and transform everyday life, mainly by means of revolutionary fifth-generation(5G) technologies. These are characterized by concepts such as, cell-less architectures, massive spatial processing, tactile response times, big data processing and virtualization. Many groundbreaking technological advances are currently considered as promising enablers for realizing the 5G expectations. To achieve the world’s first commercialization of 5G, mobile communication companies of Korea are preparing or performing dynamic activities including 5G wireless network design. Wireless network analysis and design are very critical processes, because initial network performance and QoS(Quality of Service) of 5G are mainly depend on these. We tried to develop the simulation tool(CellPLAN) for 5G wireless network design referred to 5G pre-New Radio(NR). In this paper, We want to emphasize the importance of Geographic Information System(GIS) in 5G wireless network design. To do this, we listed on the essential information for 5G wireless network design, such as GIS, candidate site information, and propagation model. To focus on the effects of building information(location, shape, height) in 5G wireless network design, we select the sample area and make the possible error intentionally in digital map of CelLPLAN. And we analyzed the difference between original case and error case in the respect of Reference Signal Received Power(RSRP). These works can give a good insight of necessity of one simulation tool to increase reliability and performance in the field of 5G wireless network design and optimization.
