¿µ¹®³»¿ë¿ä¾à ITU 5G vision present the 3 usage scenario and 8 key capabilities. 3 usage scenario is the Enhanced Mobile Broadband (eMBB), Ultra-reliable and low latency communications (URLLC), Massive machine type communications (mMTC). Considering the mobile communication market is already governed LTE technology, 5G technology would extend its areas to Internet of Things, Public Safety, Vehicle to Vehicle communication, etc., and could be used for social basic infrastructure. Although 4G vision is just highlight the mobility and peak data rate, 5G vision includes the more key capabilities such as user experienced data rate, latency, connection density, energy efficiency, spectrum efficiency and area traffic capacity. Also, this 5G vision includes the observation of trends, relationships of IMT technologies, timelines, etc.
