  The increasing demand for ultra-high throughput in ultra-dense networks might
take a toll on 5G capacity. Moreover, with Internet-of-Things (IoT) and the
growing use-cases for indoor killer-applications, it will be necessary to look
beyond 5G technologies. One such promising technology is to move higher in the
frequencies, such as the THz ($300$ $GHz$-$10$ $THz$) spectrum. THz has a
massive number of greenfield-contiguous channels ranging from $10$ $GHz$ to
$200$ $GHz$ (best case), which was not available in the traditional radio
frequency (RF) or millimeter wave (mmWave) bands. Although THz has immense
potential to cater to such demands, it comes with numerous challenges revolving
around hardware, link budget, mobility, blockages, scheduling, and deployment.
Terahertz access points (THz-APs) are sensitive to deployment and can
critically impact a system\textquotesingle s dynamics (i.e., coverage,
throughput, and efficiency). In this paper, we present Strategies for
High-frequency INdoor Environments or SHINE, which focuses on efficient AP
deployment in the THz spectrum and draws motivation from approaches used indoor
to improve lighting conditions. Due to THz\textquotesingle s limited coverage
area of a few meters, the number of THz-APs required to satisfy a densely
populated room will be higher compared to today's single router/box/AP model.
This increased number of THz-APs will not only increase the operational costs,
but also (in some cases) can make the system inefficient. Through SHINE, we
explore the deployment-related challenges and propose strategies to mitigate
the same.
