The increasing demand for ultra-high throughput in ultra-dense networks might\ntake a toll on 5G capacity. Moreover, with Internet-of-Things (IoT) and the\ngrowing use-cases for indoor killer-applications, it will be necessary to look\nbeyond 5G technologies. One such promising technology is to move higher in the\nfrequencies, such as the THz (300 GHz-10 THz) spectrum. THz has a\nmassive number of greenfield-contiguous channels ranging from 10 GHz to\n200 GHz (best case), which was not available in the traditional radio\nfrequency (RF) or millimeter wave (mmWave) bands. Although THz has immense\npotential to cater to such demands, it comes with numerous challenges revolving\naround hardware, link budget, mobility, blockages, scheduling, and deployment.\nTerahertz access points (THz-APs) are sensitive to deployment and can\ncritically impact a system textquotesingle s dynamics (i.e., coverage,\nthroughput, and efficiency). In this paper, we present Strategies for\nHigh-frequency INdoor Environments or SHINE, which focuses on efficient AP\ndeployment in the THz spectrum and draws motivation from approaches used indoor\nto improve lighting conditions. Due to THz textquotesingle s limited coverage\narea of a few meters, the number of THz-APs required to satisfy a densely\npopulated room will be higher compared to today's single router/box/AP model.\nThis increased number of THz-APs will not only increase the operational costs,\nbut also (in some cases) can make the system inefficient. Through SHINE, we\nexplore the deployment-related challenges and propose strategies to mitigate\nthe same.\n
