Analyzing the impact of ITS mobile node antenna HPBW on primary network SINR

Abstract

<p>The development of communication systems worldwide provides an additional load on both licensed and unlicensed spectrum. One of the biggest segments influencing the unlicensed one is Intelligent Transportation Systems (ITS) as part of the Smart City paradigm. One of the potential solutions to reduce the interference picture is by improving the spatial reuse of the system, i.e., by utilizing directional antennas on the vehicle side. This work aims to analyze the radiation pattern spatial characteristics of the antenna installed on the vehicle to be developed for cases when static ITS infrastructure nodes are located on the roadside light poles and primary network operating in the same frequency range is located in different locations: same light pole; roadside unit; or building. As a result, the recommendations regarding the antenna parameters are given for each case.</p>
