Abstract

As the cellular networks continue to progress between generations, the expectations of 5G systems are planned towards high capacity communication links that can provide users access to numerous types of applications (e.g., augmented reality, holographic multimedia streaming). The demand for higher bandwidth has led the research community to investigated unexplored frequency spectrum, such as the terahertz-band for 5G. However, this particular spectrum is strived with numerous challenges, which includes the need for Line-of-Sight (LoS) links as reflections will deflect the waves as well as molecular absorption that can affect the signal strength. This is further amplified when high Quality-of-Service (QoS) has to be maintained over infrastructure that supports mobility as users (or groups of users) migrate between locations, requiring frequent handover for roaming. In this paper, the concept of mirrorassisted wireless coverage is introduced, where smart antennas are utilised with dielectric mirrors that act as reflectors for the terahertz waves. The objective is to utilise information such as the user's location, and to direct the reflective beam towards the highest concentration of users. A multi-ray model is presented in order to develop the propagation models for both indoor and outdoor scenarios, in order to validate the proposed use of the reflectors. An office and a pedestrian walking scenarios are used for indoors and outdoors scenarios, respectively. The results from the simulation work shows an improvement with the usage of mirror-assisted wireless coverage, improving the overall capacity, received power, path loss and probability of line of sight.
