    In future mobile communication systems, more users will rely on mobile data services while riding public transportation vehicles for either working or entertainment. To serve these vehicular users effectively, the deployment of moving base stations on public transportation vehicles is considered as one of the most promising solutions. Each public transportation vehicle forms a moving network (MN) inside the vehicle to serve the users on board. In this paper, we study the deployment of MNs in an ultra-dense urban scenario, and we identify that one of the key challenges is the inter-cell interference, which is worsen by the street canyon effects. In order to address this problem, we employ and compare various solutions to enhance the performance of MNs. We show that by using MNs that have advanced multi-antenna systems, the quality of service at the vehicular users is noticeably improved without obvious influence on the performance of regular outdoor users.
