- Abstract
The use of millimeter-wave for 5G connections seems ready to be implemented. The high-path loss problem as a consequence is solved by the use of antenna arrays and the reduction of cell coverage with a small cell concept. Aligning beams to the best directions is then a selected concept of antenna arrays implementation. Numerous research has addressed the concept to obtain optimal beam alignments. In addition to those, this paper investigates the impacts of antenna positions to the beam alignment in urban road scenarios. Optimizing Line of Sight (LOS) connections and investigating Nonline of Sight (NLOS) are two concerns in the scenarios. A straight road is chosen to be an example of small cell implementation in an urban environment. Furthermore, the main goal of this paper is to characterize LOS and NLOS connection for proposed antenna positions i.e. wall-mounted and lamppost scenarios. These scenarios are then carefully evaluated. The results show that the installation of the antenna on the lamppost gains more LOS connections compared to that in the wall-mounted scenario. Its installation improves EM field strength by around 5dB. In addition, the basic concept of LOS and NLOS in terms of connection due to the use of antenna arrays should be modified. A user in the LOS region is potentially served by an NLOS connection.
